These figures, though they include day as well as
evening students, but well repay analysis. Consider
first Machine Construction and Drawing, Building
Construction, Naval Architecture, and Principles of
Mining, and assume that all students in Applied
Mechanics and Steam are taking one or other of
these. Let it be granted that such students require
DIFFICULTIES AND SHORTCOMINGS 79
instruction in Mathematics and Geometry. In round
numbers we have :
Number of students taking Machine Con-
struction and Drawing, Building Con-
struction, Naval Architecture, and
Principles of Mining, ... 17,000
Number of students taking Mathematics, - 1 3,000
Number of students taking Geometry, - 3,000
Allowing for the fact that students in Machine
Construction and Drawing, Building Construction,
Naval Architecture, and Principles of Mining, are
almost entirely engaged in the respective industries,
while students in Mathematics are not necessarily
so engaged, the disparity is considerable. The case
of Geometry is serious. This subject has for
over thirty years been compulsory for Whitworth
scholarships and exhibitions, and the prospectus of
every technical school of note insists on a knowledge
of Geometry as a basis of successful work in the
subjects compared. If this regulation is not honoured
more in the breach than in the observance, the state
of affairs in the rest of the country must be bad
indeed. In fact, the writer's own observations lead
to the belief that teachers of this subject are
becoming scarce, and the following figures showing
the number of papers worked during three years fully
account for it :

became optional in 1901. The percentage drop in papers
worked in all subjects was 38, in Geometry, 60 per cent.
80 TECHNICAL EDUCATION IN EVENING SCHOOLS
Examine next the case of Steam. Notwith-
standing the fact that the syllabus includes a
considerable amount of Heat, few will deny that a
previous acquaintance with that subject is desirable
for rapid progress. The total number of students
examined in Elementary Sound, Light, and Heat,
or in the Advanced or Honours stages of Heat, was
roughly 1,500. Probably not more than half these
were engineering students. Yet the number sitting
for examination in Steam was more than 2,000.
Allow here for the students who have obtained some
knowledge of the fundamental subject by attendance
at a secondary school, and that still leaves at least
half the examinees with an unsatisfactory foundation.'
Again, by far the most popular subject in
Physics is Electricity and Magnetism. No real pro-
gress can be made in this subject without some
knowledge of Mathematics, Theoretical Mechanics,
and Chemistry ; no other subject requires such clear
conceptions of energy in order that accurate notions
may be developed. Thus : 2
" One of the most serious mistakes in the Science
teaching that is generally made is the choice of
subject. That most commonly taken is Electricity
and Magnetism, which is naturally very unsuitable
for students with no previous knowledge of Science;
The teacher, finding himself hampered by the fact
that his students know nothing of the fundamental
principles of Elementary Physics and Chemistry,
tends to fall back on generalities ; his teaching
1 This is, of course, wholly apart from the fact that both
types of student are found in the same class.

for 1902, p. 33.
DIFFICULTIES AND SHORTCOMINGS 8 1
becomes inexact, and the giving of information of
a more or less scientific character does duty for
Science teaching."
Twenty years ago there might have been some
justification for an elementary descriptive treatment
of Magnetism and Electricity. Little or nothing was
then known of the electro-magnetic field, which
concerned comparatively elementary students. But
progress has been enormous, and dynamical concep-
tions have permeated the whole subject. The standard
of the examinations has increased with the spread of
facilities for instruction and the multiplication of
text-books ; and to-day no student who aims at
exact knowledge can afford to regard it as an
independent subject. The figures on page 78 are
not without significance.
The unsuitability of choice is not only a common
result of taking up too few subjects, but occurs also
when the student has filled up his time pretty fully.
The student with too narrow a training has his
labours considerably increased, and is bound to
suffer from want of exactness and definition in his.
ideas. On the other hand, too wide a curriculum
leads to superficiality, and, occasionally, to mental
and physical breakdown. How much an evening
student can accomplish in any session depends upon
previous education, ability, and strength of purpose.
How much he can do with impunity — without serious
injury to health — is another matter, and one not
easily estimated before it is too late. In the pro-
gramme of. the Northampton Institute, Clerkenwell,
(p. 55) it is stated that : " It has been assumed that
an earnest student will be willing to devote three,
F
82 TECHNICAL EDUCATION IN EVENING SCHOOLS
or in some instances, four nights a week to study
during the winter months."
For the general run of students three nights a
week may be regarded as a maximum, and if satis-
factory progress is to be made, the greatest care is
needed in organising the curriculum. There must
be rational grouping and order of arrangement of
subjects ; the preliminary training of the students
should be known exactly, in order to prevent the
teacher groping in the dark ; the actual work on
which the student is engaged in the daytime should
be kept in view, and account should be taken of his
prospective career.
It is not intended to imply that these abuses exist
everywhere — that there is no active control of the
curriculum. There are indeed numerous instances
in which heads of technical schools exercise a
beneficent influence, and map out each student's
work with admirable care. But there are hundreds
of places in the country where there are no head-
masters, and many others where the headship is
nominal. In these cases each teacher is a "law
unto himself." There is no co-operation between
teachers, still less is there correlation of subjects.
Every subject stands on its own basis. There is
no guarantee of adequate preparation, no rational
order and grouping, and nothing but an attenuated,
ghostly caricature of a curriculum. For example:
"Even in the same town and under the same
Committee, one finds odd classes taken by inde-
pendent teachers, who are only responsible individu-
ally to the Committee. There is no one to advise
students what course to take, and indeed, the subjects
DIFFICULTIES AND SHORTCOMINGS 83
in which instruction is given depend on the teachers
locally available. To this absence of direct control
is due rivalry between classes in subjects which should
appeal to similar types of students, and even the
instinct of self-preservation does not prevent two or
three classes in different subjects, each of which
should be attended by the same students, being
held at the same hour on the same evening. The
distribution of classes amongst several schools in the
same town is frequently due to want of adequate
control and rival interests.
" Such distribution of classes leads to duplication
of apparatus and waste of money ; e.g., a piece of
apparatus is procured for illustration of Physiography;
it is equally useful for Mechanics, or Building Con-
struction, or Applied Mechanics, but these classes are
in different buildings, under independent teachers,
so each must have a similar piece of apparatus.
"As an example of lack of organisation, it may
be mentioned that in one town there are eighteen
classes in various subjects held at six different
schools, and though in the centre of the iron
industry, Metallurgy is not one- of the subjects.
The extreme distance between any two of the
schools is half- an -hour's walk. Classes in Practi-
cal Mathematics, Building Construction, Applied
Mechanics, and Steam are held at approximately
the same hour on the same evening; the most
central and comfortable school is only used for
three subjects ; though there is a good chemical
laboratory there, and suitable rooms for Art instruc-
tion, the former subject is taught elsewhere in a
laboratory cut out of half a chapel, and the latter
84 TECHNICAL EDUCATION IN EVENING SCHOOLS
in a basement room, used in the daytime for Manual
Instruction." 1
This is a picture more or less true for scores of
places. They are not schools, but mere segrega-
tions of classes, lacking in unity of aim and design,
in economy of money, time, and effort, bringing
technical education into disrepute, permitting the
growth of vested interests, and constituting a serious
stumbling-block in the path of progress.

CHAPTER IV
TENDENCIES IN EVENING TECHNICAL INSTRUCTION
If any justification is required in support of the
criticisms in the last chapter, it is to be found in
tendencies to their removal which are exhibited to
a greater or less extent by all the more important
Technical Schools. It will be convenient to describe
these under the titles : Admission Standard and
Age ; Adaptation of the Instruction to the Special
Requirements of Industry ; and Organised Courses
of Instruction.
A. Admission Standard and Age.
The evil which results from inadequate prepara-
tion is being grappled with in one of two ways.
Either the student is referred definitely to the
Continuation School, unless he can show that he
possesses the necessary qualifications, or preliminary
courses are held in the Technical School itself. The
following examples show how in one or another of
these ways an effort is being made to secure more
satisfactory material.
At St. Helens, a compulsory preliminary course
has been in operation for some years, and though
the innovation was accompanied by a reduction in
the number of new students enrolled, it has been
85
86 TECHNICAL EDUCATION IN EVENING SCHOOLS
amply justified by increased efficiency. The subjects
are Mathematics, Geometry, Elementary Science,
and English.
Rochdale has introduced a similar obligatory
course in Mathematics, English, Drawing, Physics,
and Chemistry.
The Blackburn Technical School held an entrance
examination in September, 1904, which is com-
pulsory for all those who do not hold scholarships
from the higher division of the Continuation Schools.
Candidates for admission are examined in English,
Arithmetic, Mensuration, Algebra, and Geometrical
Drawing.
Stockport provides a preliminary course in Arith-
metic, Freehand and Geometrical Drawing, and
Elementary Science, and students are only excused
if they can pass an entrance examination in these
subjects.
At Liverpool, students are recommended to join
the branch preparatory classes or the Continuation
Schools before proceeding to the Technical School.
Students at Huddersfield are advised to take a
course comprising Freehand and Model Drawing,
Arithmetic and Mensuration, and Practical Geometry;
at Derby the subjects are Mathematics, Machine
Drawing, and Geometry.
Swindon suggests a preliminary course in Practical
Mathematics, Practical Geometry, and Practical
Mechanics.
Bradford has arranged a preliminary course for
Engineering students in Mathematics, Geometry,
and Drawing (with workshop practice if desired).
West Ham provides several courses. Thus
EVENING TECHNICAL INSTRUCTION 87
students engaged in Mechanical and Civil Engineer-
ing, Naval Architecture, Foundry Work, and
Building, are recommended to do Preliminary
Practical Mathematics and Technical Drawing;
for those engaged in Electrical Engineering and
Applied Chemistry, a class in Preliminary Physics
is suggested in addition.
The standard of admission to the Manchester
Municipal School of Technology is the Seventh
of the Elementary School. In some cases where
special preparatory knowledge is required, students
must show that they are able to follow the
instruction.
At Preston, students are recommended to attend
the Continuation School unless they have a sound
knowledge of the three R's.
In certain subjects at West Hartlepool, students
are required to show that they possess the special
knowledge which is necessary to enable them to
follow the work, while Rutherford College, New-
castle-on-Tyne, follows the old plan of specifying
certain requirements in connection with each subject
of instruction.
No definite standard appears to be set up at
Bristol. The Continuation School Scheme was
described in Chapter II.
It may be noted that while there is considerable
diversity of opinion as to what constitutes a complete
preliminary course for technical students, there is
agreement on certain essentials. Thus the nine
cases given above, in which the subjects are specified,
include Arithmetic, Mensuration, Mathematics, and
some form of Drawing. Physics, Chemistry, or
88 TECHNICAL EDUCATION IN EVENING SCHOOLS
Elementary Science only occur in four schemes.
English would probably be an invariable constituent
of courses in Continuation Schools, and appears in
three of the courses mentioned above, which are
held in Technical Schools. A general discussion
of essentials has been given in Chapter II.
Comment has already been made upon the
variability of age in evening technical classes. The
lower limit imposed by the Board of Education,
provided the student has left school, is twelve.
While at present there is no uniformity in the
regulations of the schools on this point, there is
an indication of unwillingness to conform to the
minimum. At Birmingham, students must be
thirteen ; at Brighton, fifteen ; at Sheffield, Bristol,
and Bradford, sixteen. In the latter place, an
exception is made in favour of students who have
passed through the preparatory district textile
classes. There can be no doubt that but little
serious technical instruction can be given to students
under sixteen years of age.
B. Tendencies towards Adaptation to Industrial
Requirements.
Until quite recently classes throughout the
country have been conducted in accordance with
the syllabuses of the central examining bodies.
The growing specialisation of industry and the
development of new manufactures have rendered
new subjects necessary, and where these have not
been introduced, the gap between the classes and
the needs of neighbouring industries has .become
EVENING TECHNICAL INSTRUCTION 89
Avider. In other cases the additions to syllabuses
issued by central bodies (e.g., Building Construction)
have been met by special classes in which instruction
has been given to meet new requirements. Some of
the innovations may be briefly noticed.
At University College, Sheffield, there is a course
on Machine Tool Work, which deals with those
matters which a man may spend years in the shops
without learning. Students are not admitted unless
they have (a) been in the works for at least three
years, and have been engaged in working machine
tools during a portion of that time, or can pass
an examination in vice - work and the simple
manipulations of machine tools; (b) have attended
science classes for at least one year previously and
obtained a certificate in Machine Drawing, or can
show that they possess equivalent knowledge.
The syllabus is as follows :
The cutting of spur, bevel, worm, and other kinds
of wheels in the milling or planing machine.
The making of formed cutters for wheels and twist
drills. Making of forming tools for lathe work, or
work of an irregular shape.

Objection may be taken to these syllabuses on the
ground that they aim at teaching a trade, and that
therefore they are outside the scope of what the
Legislature has defined as legitimate subjects for
public expenditure. It has, however, already been
observed that it is extremely difficult to separate
the teaching of principles from the teaching of
practice, and in the eyes of some people, extremely
undesirable also. And it is, moreover, quite im-
possible in many cases to judge whether the
limitations are exceeded from a study of the syllabus.
G
98 TECHNICAL EDUCATION IN EVENING SCHOOLS
The question is determined entirely by the method
of treatment in class, and the syllabuses permit of a
thoroughly scientific method of presentation, while
they deal with subjects of the highest importance.
No one can read current engineering literature with-
out being impressed by the superiority of American
methods. American machine tools have had an
enormous effect in reducing the cost of production,
and have practically revolutionised some branches
of industry, of which watch- and clock-making may
be cited as an example.
The information contained in the above syllabuses
should be part and parcel of a shop foreman's equip-
ment. At the same time, the number of really
qualified men of this type available is small. Thus,
in a paper read at a conference of science teachers at
University College, Sheffield, on i ith January, 1900,
Professor Ripper said : 1
"It is clear from what has already been said that
we need the means of securing a steady supply of
skilled machinists and toolmakers with a competent
knowledge of up-to-date methods of turning work
out, and of the best types of machine tools — men, in
fact, who are competent to become, in course of time,
leading men and works' foremen.
" There are, of course, works' foremen in England
second to none in the world, but everyone knows,
who has any knowledge of works, that such men are
singularly scarce, and when a vacancy occurs, ex-
tremely difficult to replace. These men are the
brain of the workshop, and upon their skill depends
1 Nature, 8th February, 1900.
EVENING TECHNICAL INSTRUCTION 99
very much of the true success of any manufacturing
concern. Almost any man in the works could be
more easily replaced than the skilled works'
foreman."
A reasonable conclusion would be that there is
also a dearth of teachers capable of giving the
requisite instruction.
Another interesting course is that on Foundry
Practice at the West Ham Technical School. The
following subjects are treated of in the Lectures :
Properties and mixtures of pig iron ; fuel, furnaces,
refractory materials ; methods of blast production ;
crucibles, ladles, and foundry tools ; green sand, dry
sand, and loam, their preparation and moulding in
them ; drying stoves ; malleable cast iron ; chill
castings ; case hardening ; casting on to other
metals ; special methods of casting ; machine
moulding; cleaning and dressing castings.
Brass, gun-metal, and other common alloys, their
compositions and methods of melting and casting
in them.
Methods of costing work.
The freedom to draw up schemes and time-tables
conferred on local authorities by the Board of
Education, 1 together with the readiness of the City
and Guilds of London Institute to modify their
syllabuses as occasion may require, 2 will probably
lead to an increase in the amount of such instruction,
1 Regulations for Evening Schools, 1904, p. 3 et seq.
2 Report of City and Guilds of London Institute, 1902.
100 TECHNICAL EDUCATION IN EVENING SCHOOLS
but the provision of competent teachers who have
sufficient scientific knowledge to treat the subjects
from a proper standpoint will be a serious obstacle. 1
Of considerable interest, too, is the syllabus in
Sanitary. Engineering at the Manchester School of
Technology, which includes matter generally taught
under the separate heads of Building Construction
and Hygiene. The enormous growth of large in-
dustrial centres has created the need for numbers
of Sanitary and Building Inspectors, etc., in order
that the health of the community may not suffer
through carelessness or wilful negligence.
. One of the most serious defects in the instruction
of engineering and building students is the lack of
attention to the nature and properties of materials.
At the Birmingham Municipal Technical School
there is* an advanced course suited to the needs of
Civil and Mechanical Engineers and Architects
which to some extent supplies this deficiency. A
good deal of it might be described as descriptive
engineering. The syllabus is as follows :
Part i. Ironwork — The manufacture of cast iron,
wrought iron, and steel ; description of the plant .used
in modern iron and steel works ; the different kinds
and qualities of cast iron, wrought iron, and steel;
the commercial forms of iron and steel ; pattern-
making and moulding; iron and steel casting; the
mechanical properties of cast iron, wrought iron, and
steel, and the methods of testing ; the practical value
1 See also syllabuses of special trade classes held at the
Birmingham Municipal Technical School, the Northampton
Institute, Clerkenwell, and other institutions.
EVENING TECHNICAL INSTRUCTION IOI
of various metalloids in cast iron and steel ; the use
of iron and steel in engineering structures and
machinery ; the manufacture and erection of struc-
tural ironwork. Other Metals and Alloys — Their
strength and principal uses in engineering. Modern
Machine Tools — Description of modern machine tools
and labour-saving appliances ; general arrangement
of engineering works.
PART 2. Earthwork — Stability of earth ; effect of
water on stability ; cuttings, embankments, and dams ;
clay puddle, its preparation and use ; foundations for
buildings, bridges, and machinery ; methods of laying
submerged foundations ; sinking shafts ; tunnelling ;
dredging ; description of the plant used for earthwork
operations. Masonry — Strength and properties of
various stones ; different classes of masonry ; the
selection and preparation of stone for different kinds
of engineering work. Brick, Cement, and Concrete —
Their manufacture, properties, strength, methods of
testing, and use in engineering work. Timberwork —
The principal kinds of timber and their use in
engineering; strength of timber; preservation of
timber.
The strength and properties of the materials will
be demonstrated in the Engineering Laboratory.
The introduction of Mechanics into the Board of
Education Syllabuses in Building Construction has
been met in a number of instances by special
courses of instruction in graphic statics. An
arrangement of this sort has been made at Derby,
Birmingham, Manchester, Brighton, Darlington, etc.
At Salford there is a special course in Builders'
102 TECHNICAL EDUCATION IN EVENING SCHOOLS
Mechanics. In regard to the arrangement of classes
in Chemistry and Physics with reference to their
applications to particular trades, the most notable
examples are in connection with Plumbing. A
considerable number of Technical Schools now
provide special classes for this trade, in which an
elementary knowledge of Physical Science is of the
greatest importance. Examples of special classes
for Engineering and other industries are seldom
met with. At the same time large schools, such as
those at Manchester and Bradford, hold classes in
Physics — covering the whole ground of the subject
— which are specially recommended as forming a
necessary basis for advanced technical studies.
An attempt has been made in the larger institutions
to meet the particular needs of students by treating
highly specialised branches separately, and often in
short courses. Thus, Applied Mechanics may be
treated in sections, each dealing with a particular
part of the subject. The most remarkable example
of this method is probably to be found at the
Northampton Institute, Clerkenwell, where a limited
number of teachers give instruction in short " unit "
courses, which apparently can be grouped to suit
any need that has arisen, or is likely to arise.
Finally, the following list 1 of subjects, bearing
upon the industries considered, in which grants
were claimed from the Board of Education in
1902-3, will indicate the activity which is being
displayed throughout the country in meeting
the need which has been created by industrial
specialisation.

C. Organised Courses of Instruction.
Though for a number of years the larger Technical
Schools have done much in their Prospectuses, or
through the teachers, to encourage students to
attend such classes as will secure a more or less
104 TECHNICAL EDUCATION IN EVENING SCHOOLS
rational order and grouping of subjects, the tendency
has been more marked and widespread in recent
years. Most Technical Schools of any note, have
drawn up tables showing the order and grouping
of subjects for particular trades, but while in all
cases students are strongly advised to follow the
systematic courses of instruction, only three have,
so far as the writer is aware, made such courses
compulsory. As a general rule, the plan has been
to take subjects from the Board of Education
Directory and the Programme of the City and
Guilds of London Institute, and to weld these into
trade groups ; but in a few cases special courses of
Lectures and Practical Work have been instituted
in subjects which none of the Central Examining
Bodies have as yet recognised by the provision
of an annual test. In discussing the courses of
instruction, it will be convenient to consider them
under the titles of the trades, rather than of the
schools. This will be consistent with the attitude
adopted throughout this work, in which it is regarded
as essential that the instruction and organisation
should be based upon the industrial considerations.
I. — General Mechanical Engineering Courses.
The suggested duration of the courses is from
three to five years. In only three cases are
compulsory preliminary courses provided, viz. : at
Stockport, St. Helens, and Rochdale. So far as
the courses themselves are concerned, there is
considerable difference of standard, and no small
want of unanimity as to subsidiary subjects.
The following table is an analysis of the courses

given on pp. 1 10-120; the figures represent the
number of courses in which one, two, or more years
are devoted to each subject :

The general aim is to give the students a pro-
gressive course of instruction which shall culminate
in the second or third stages of Machine Drawing,
Applied Mechanics, and Steam. In order to attain
this, various views appear to be held as to the
amount of Mathematics and Geometry required to
render the more technical subjects intelligible.
So far as the first-named subject is concerned, it
is extraordinary that any teacher should regard
one year as sufficient, unless the standard on
entrance is exceptionally high. Even two years,
which the majority of courses entail, is little enough.
A particularly interesting feature is the number
of cases in which Practical Mathematics is taken,
no less than nineteen out of twenty-six courses
including that subject. In regard to Geometry, the
difficulty seems to be to decide whether anything
106 TECHNICAL EDUCATION IN EVENING SCHOOLS
beyond the elementary stage is essential. Of the
eleven courses in which two years are devoted to
the subject, about half are aiming at Stage I., and
the rest at Stage II. For most classes of work in
Machine Drawing, Stage I. of Geometry is ample,
while for higher work in Applied Mechanics, the
necessary graphics would fall on Stage II.
No one can read intelligently an engineering
text-book or journal without some knowledge of
Physical Science. This statement is truer every
day, and it is of interest to inquire what notice
has been taken of this point in arranging the
curricula under consideration. Only six courses
provide instruction in Sound, Light, and Heat, and
two in Advanced Heat. The introduction of Heat
has doubtless been delayed to a considerable extent
by its association in the elementary stage with
Sound and Light — subjects which have but a small
bearing upon the work of an engineer, however
important they may be as part of a liberal education.
Physics cover . a wide area, and the division into
Sound, Light, and Heat, and Electricity and
Magnetism, is almost universal. At the same
time, there is no inherent reason why Heat should
not be taught separately. One of the consequences,
however, is that out of twenty-four courses in which
Steam is taught, twelve 1 make no provision for
instruction in Heat. Of course, in most cases, the
teacher of Steam includes a certain amount of
Heat in his lectures. How far this may be sufficient
1 Elementary Science or Physics is part of Preliminary
Courses at Rochdale, St. Helens, and Stockport. Also
Practical Class in Steam at Salford is really Practical Heat.
EVENING TECHNICAL INSTRUCTION to;
depends largely upon the individual, and in any
case he would probably prefer students with a
satisfactory preliminary training.
The applications of Chemistry to Engineering
are now increasing, and the desirability of
students having some knowledge of Metallurgy
has occasionally been emphasised. Three schools
insist on Elementary Science (Physics and Chemistry)
in the preliminary course, but beyond that only
three courses contain Chemistry, and two of these
add Metallurgy. Birmingham has a course on the
Materials of Engineering and Processes of Con-
struction, which includes the essentials of Metallurgy,
Nature of Building Materials, and some Applied
Mechanics. To those whose duty it is to follow
closely improvements in Materials, this lack of
instruction in Chemistry cannot fail to be a serious
loss.
The fact that many classes, especially in large
towns, contain a fair proportion of students who
have passed through secondary schools is not here
lost sight of. But in the absence of a definite
standard of admission in these subjects, too much
should not be taken for granted. Most of the
courses give evidence of having been carefully
thought out ; a few are not only educationally
unsound, but have the misfortune of being at
variance with the time-table. The latter are inserted
as a warning.
The majority occupy three nights a week ; a few
only two nights; while several require every night
in the week. Thus out of twenty-three courses, for
which data have been collected, fourteen devote three
IOS TECHNICAL EDUCATION IN EVENING SCHOOLS
nights a week in the first year, thirteen three
nights a week in the second year, and thirteen
three nights a week in the third. There is thus
fair agreement as to the number of nights' work
a week which can be expected from the average
student. A greater number of nights per week
than three cannot be considered satisfactory unless
due to the inclusion of Laboratory or Workshop
instruction. Practical work is less fatiguing than
the close mental attention required to follow lectures,
and it does not as a rule increase the amount of
reading required from the student. To what extent
it should be introduced into Evening Technical
Education will be considered in Chapter VII.
Some of the courses deserve special mention. It
has been said that the general aim is to lead the
student through a progressive course -of instruction
in the specifically engineering subjects until he
reaches a standard of knowledge represented by
the second stage in a three or four years' course,
or the third stage, or higher, in a six years' course.
This is in the main true ; but there are some
points of difference. Thus the courses at Bolton
appear to aim at giving the student a general
grounding in the subjects which underlie Engineer-
ing, rather than to aim at a higher standard in
Mechanics, Steam, or Machine Drawing, as in
other five year courses (cf. Newcastle). The
extent of difference in providing instruction in the
fundamental subjects has been already noted.
West Ham follows the courses for the degree in
Engineering at the University of London. In
these syllabuses, subjects are grouped below the
EVENING TECHNICAL INSTRUCTION 109
senior stages : thus Mechanical Engineering includes
both Applied Mechanics and Steam, and Engineer-
ing Drawing, Geometry and Projection. This
simplifies the time-table. The senior stages are
broken up, and the special courses, B D and E, are
similar to those in the fifth year at Birmingham,
and the fourth and fifth years at Manchester.

EVENING TECHNICAL INSTRUCTION 121
II. — Minor Mechanical Engineering Courses.
In a number of schools it has been recognised
that the standard of theoretical instruction aimed
at in the general courses is too high for those from
whom will be chosen the minor officials. Courses
of instruction have therefore been drawn up in which
Mechanics and Steam, for example, are not carried
beyond the elementary stage, and the standard of
mathematical knowledge has been similarly restricted
so as to bring it within the needs and capacity of
the average shop foreman. The theoretical training
required by these men must of necessity be closely
associated with the ordinary operations and processes
of the workshop ; practical instruction is therefore
highly essential, and probably explains why the
courses have so far been arranged only in connection
with the larger institutions.
Engineering work, after the necessary drawings
have been completed, passes in order through the
pattern shop, foundry, or smiths' shop, fitting and
turning, or boiler shop, in the order given. These
represent, broadly, the divisions for which instruction
may conveniently be arranged.
All courses, it will be noted, provide for the
teaching of simple Mathematics and a fair amount
of Geometrical Drawing, with Machine or other
Drawing peculiar to the special branch of the trade.
Some Applied Mechanics is also generally included.
A point of interest is the essentially practical char-
acter of the instruction at Birmingham, which,
however, does not appear to be progressive.
In connection with the instruction for special
branches of the trade, it may be noted that the
122 TECHNICAL EDUCATION IN EVENING SCHOOLS
courses at Bolton grouped in the major division
really belong here. They are worthy of close atten-
tion because of the manifest attempt to give a broad
basis of scientific knowledge without too much
specialisation. At the same time, they do not include
practical teaching in the workshop, and exception
might be taken to the order of treatment on
educational grounds.
In smaller towns a course of instruction of this
type is really what is required. Only the larger
towns, as a rule, can supply a sufficient number of
men capable of following the general courses. It
is somewhat unfortunate, therefore, that the more
ambitious schemes are universal in smaller places,
where, but for the absence of workshops — and
probably workshop instructors also — the more modest
scheme would be desirable. This question will be
further discussed in Chapter IX.

This table is an analysis of fifteen courses, as
against twenty-six in Mechanical Engineering. It
will be noted that there is rather more uniformity
as to the number of years of study to be given to
Mathematics. The conclusion to be drawn is that
Mathematics is considered of more importance in
Electrical than in Mechanical Engineering. It is
interesting to note that ten of the fifteen courses
prescribe Practical rather than Pure Mathematics.
Geometry does not appear to be regarded as an
essential subject, and it is somewhat surprising to
find that only four courses include this subject, while
eleven propose Machine Drawing.
Electrical Engineering is commonly said to consist
of two-thirds Mechanical Engineering and one-third
128 TECHNICAL EDUCATION IN EVENING SCHOOLS
Applied Physics, and that this view is general is borne
out by the attention given to Machine Drawing,
Applied Mechanics, and Steam.
Electricity and Magnetism is recommended for
one or two years in all but three of the courses ;
those three — Bradford, West Ham, and Salford —
start right away with the more practical subject.
The educational value of this branch of Physics,
considered alone, is doubtful ; its connection with
Dynamics, Heat, and Light is so close, that some
general knowledge of Physics is essential. Yet only
four courses provide for this.
One other matter deserves notice. While in the
Mechanical Engineering courses only three out of
twenty-six include Chemistry, in the younger in-
dustry four out of fifteen contain it. In which
industry is a knowledge of Chemistry in its relation
to the property of materials of greater importance,
and in any case would the above figures express the
relative importance? Electro-metallurgy is not taken
into account, as for it special courses are provided.
IV. — Minor Electrical Engineering Courses.
The only Minor Electrical Industry that need be
mentioned is Electrical Wiring and Fitting. Three
courses are given, and there is a general similarity as
to grouping and order of subjects. Some knowledge
of Elementary Physics and Chemistry, similar to
that usually given to plumbers, might be thought
desirable.

EVENING TECHNICAL INSTRUCTION 141
VI. — Minor Courses in Building.
The recommendation in some of the General
Courses to attend the City and Guilds subject
bearing on the student's own branch of the trade is
in most cases considered a sufficient concession to
specialisation. A few schools have, however, drawn
up special courses, in which, while a general know-
ledge of the principles underlying the whole trade
are kept in view, the curriculum aims at giving the
student the highest possible knowledge of his own
particular division.
The two courses in Carpentry and Joinery call for
little comment. They are very similar, the extra
year required for the Salford course being balanced
by the Compulsory Preliminary Course at St. Helens.
The courses in Sanitary Science contain no par-
ticular point to which attention need be drawn,
unless it is the tendency to over-weight them in the
first year.
The courses in Plumbing possess some points of
interest. It is not quite clear, for example, why
Theoretical Mechanics is necessary for this trade,
especially as Solids is chosen. The Fluids Section
would be quite appropriate. However, in all these
cases, as will be clear later, regard must be had to
the organisation of the school, and if the exact
subject required to fit any particular trade cannot
be arranged for, the nearest one must be substituted.
At St Helens, Practical Mathematics and Theoretical
Mechanics are taken together, and are common to all
the courses.
In most places it is customary to leave instruction
143 TECHNICAL EDUCATION IN EVENING SCHOOLS
in Elementary Physics and Chemistry to the teacher
of Plumbing. The small amount of instruction that
can be given in these subjects under the circum-
stances is supplemented by additional classes in the
courses at Preston, Manchester, and Bristol. The
second year's course at Manchester is rather heavy ;
if Mechanics and Physics replaced workshop in-
struction, a better balance would be obtained. The
Bristol course is remarkable as including Physiology
and excluding Physics.
There is a greater desire manifested in these
Plumbing courses to include the Physical Science
underlying the practice, than in the courses for any
handicraft that have yet been considered.

VIII. — Courses in Metallurgy.
Of the four courses given on page 151, those of St.
Helens and Longton deal with the subject purely
from the chemical side. They provide a fairly
satisfactory course of study for those engaged in
Metallurgical Laboratories. The Longton course
insists on a fairly extensive knowledge of Inorganic
Chemistry, but ignores any lack of Mathematical
knowledge. On the other hand, the St. Helens
course does not pursue Chemistry further than the
Elementary stage, but involves two years at Practical
Mathematics. They are alike in failing to regard
Physics as essential, and in making no provision for
instruction in it. The amount of knowledge of this
subject required for the daily operations of the
Metallurgical Chemist is probably not great, but
modern progress cannot be followed without a good
grasp of the fundamental principles of Heat and
Electricity.
The Manchester course treats the whole subject
more from the point of view of the Works Manager
than from that of the Chemist. The only points
which invite comment are the single year devoted to
Physics and the three years' course in Mineralogy.
The Swansea course recognises the importance of
both Chemistry and Engineering, cuts down the
essentials of Physics to one year at Electricity and
Magnetism, and apparently regards Mathematics as
unnecessary.

152 TECHNICAL EDUCATION IN EVENING SCHOOLS
Some interesting courses have been drawn up .by
the County Council of the West Riding of Yorkshire,
to be followed by holders of Technical Exhibitipns
(see p. 203). They require that on not less than two
nor more than three evenings per week, not less than
two nor more than four subjects be taken in any one
year. The Junior Courses are intended for students
between fourteen and sixteen years of age ; the Senior
for those over sixteen. The scheme is intended to
be suggestive rather than definite, and as will be
indicated later, in some cases the elasticity destroys
the benefit which it is hoped to reap from prescribed
curricula.
One of the most satisfactory features is the
insistence upon an adequate preliminary training ; in
no case is an applied subject compulsory in the
Junior Course. The sentiment that permits a student
to waste his time at a subject for which, though
bearing closely upon his occupation, he has had no
suitable preparation, is evidently less prevalent in
Yorkshire than in most other counties. There are
districts where the return on public expenditure is
less closely safeguarded.
The Junior Schemes involve thorough preparatory
training in Mathematics and Drawing. The elements
of Physical Science is always an optional subject,
and is probably frequently taken.
The introduction of Woodwork and Metal Work
is worth attention. There are always students who,
while capable of a certain amount of theoretical
study, have their limitations in this respect, and yet
possess more than ordinary manual dexterity. Such
students will probably do well to follow the workshop
EVENING TECHNICAL INSTRUCTION I S3
courses offered, for though the need of skilled labour
is rapidly dying out in most industries in which
machinery has been introduced, the necessity for
clever craftsmen here and there still exists.
The elasticity of curricula, as has already been
remarked, is a disadvantage. The view that it may
be due to the desire to cater for special branches of
the main trade is not borne out on closer inspection.
A more reasonable explanation would be that the
limitations due to the staff, etc., of recognised schools
makes alternatives imperative, the exhibitions being
tenable at one or other of some forty centres of
instruction. But whatever the cause, the alternatives
provide ample scope for irrational order and
discontinuity to creep in.

CHAPTER VII
SUBJECTS AND METHODS OF INSTRUCTION
BEFORE an attempt is made to describe how curricula
may be drawn up to meet the needs of particular
classes of students in such a way that comprehensive-
ness is secured with the greatest economy of time and
effort, it will be desirable to deal briefly with the chief
subjects of instruction.
Since, moreover, methods of teaching are largely
determined by the teacher's conception of the objects
of his instruction, occasional references to matters
under this head can hardly be avoided.
The subjects will be considered in the following
order: Mathematics, Geometry, Physics, Chemistry,
Drawing, Applied Mechanics and Steam, Mining,
and Workshop Instruction.
For the courses to be considered the question
never arises as to the inclusion or exclusion of
Mathematics, but always as to the amount. In
deciding this question, there are three considerations
to be taken into account :
(i.) How much is required in order to enable a
man to perform the ordinary calculations he
meets with in his every-day work ?
(2.) How much is required to enable him to follow
the instruction in Applied Science that may be
essential ?
•7TS
SUBJECTS AND METHODS OF INSTRUCTION 219
(3.) How much is required to enable him to follow
current literature bearing on his own branch of
the trade ?
In seeking for answers to these questions, consider
the case of the Engineering student first. So far as
(1) is concerned, the amount is probably small, and
will depend entirely upon the character of the student's
employment. Occasionally men who have taken
trouble to perfect their knowledge of this subject are
disappointed at finding so little use for it in actual
practice. Thus " Mernok," writing to the Engineer?
states that he has only used the calculus
twice, and hyperbolic functions once in twenty-five
years; while "Junior Draughtsman," writing to the
same paper, 2 says he only knows one office where
Higher Mathematics are employed. There is no
doubt that the bulk of engineering work is carried on
according to rules, tables, and data accumulated
during years of trial, and that the amount of
calculation to be done by men in practice is small,
and is concentrated in a few offices. For the shop
foreman or the ordinary draughtsman the amount of
mathematical knowledge of immediate necessity is
represented by the first stage of the Board of
Education Syllabus in Practical Mathematics. This
involves quick and approximate methods of dealing
with vulgar fractions and decimals, logarithms,
extraction of square and cube roots, mensuration of
surfaces and solids, algebra as far as quadratic
equations, graphical representation of varying quan-
tities, with determination of the " law " in simple
cases. Under (2) the amount necessary will depend
1 8th May, 1903. 2 1st May, 1903.
220 TECHNICAL EDUCATION IN EVENING SCHOOLS
upon the stage of progress aimed at in Applied
Mechanics and Steam. An elementary knowledge
such as is indicated above will be sufficient if the
student desires only a practical working knowledge of
what is usually regarded as second year work in these
subjects. If, however, he is capable of proceeding to
more theoretical and deeper study of Applied Science,
a more advanced knowledge of Mathematics will
be not only desirable but necessary.
The third factor to be employed in assessing the
extent of Mathematical instruction is the most
important. If a man is to keep in touch with
engineering progress — and no educational institution
can ignore the paramount necessity of placing its
pupils in such a position that they can continue
their studies after leaving with advantage — he
must read current engineering literature. For this
purpose a fair knowledge of Algebra, Geometry, and
Trigonometry should at least be acquired. If the
student is destined to occupy one of the more
important positions in the industry, he will find
himself severely handicapped unless he is familiar
with the calculus and its simpler applications.
Exceptions may be made in favour of the distinctly
non-mathematical student, whose ability in other
directions may compensate to some extent for a
lower standard in this most important subject.
In regard to Mining, the requirements are not very
different from those just considered. The opinion
has already been expressed that the colliery manager,
and the under manager who acts as his deputy, is, or
should be, mainly an engineer.
The needs of Metallurgical Chemists might be
SUBJECTS AND METHODS OF INSTRUCTION 221
expected to be very modest, were it not for the
fact that Physics finds an ever-increasing application
in this industry. An estimate of the amount of
mathematical knowledge ought to have regard to
the extent of the student's physical studies. The
scope illustrated on page 219 will enable the student
to follow the instruction in the second stage of the
Board of Education Syllabus in Heat; it will be
deficient in Trigonometry for the second stage in
Electricity, and quite inadequate for the second stage
in Light.
In Building, the average student will find a sound
knowledge of mensuration sufficient for his purpose.
If, however, he proposes to prosecute his studies into
the higher branches of construction, as in the case of
an architect's pupil, his mathematical acquirements
ought to be on the scale of those of an engineer.
So much has been written on the teaching of
mathematics in recent years that a full discussion of
the subject here is unnecessary. The general trend
is to curtail the treatment of those portions which
have no practical bearing, to avoid examples which
are merely exercises in mental gymnastics, to con-
centrate attention on the value of the subject as a
weapon to overcome difficulties, and to secure more
exact notions in more concrete subjects. If this is
the tendency where the school-boy is being con-
sidered, how much more essential is the new method
in the case of technical students who have little
time at their disposal, are by no means uniform in
their mathematical faculty, and regard the subject
as entirely subsidiary to their main studies? The
new ideas have immensely widened the prospects of
222 TECHNICAL EDUCATION IN EVENING SCHOOtS
technical students, and rendered it possible for
them to undertake much that was formerly beyond
their reach.
The method of regarding mathematics merely as
an aid to the study of other subjects necessitates the
introduction of mathematical truths at a stage when
they cannot be rigidly proved, and this practice is
liable to be abused. Good judgment is necessary in
deciding questions of this sort. For example, the
nature of logarithms may be explained to a student
very soon after he has completed his study of
decimals — when he understands- the meaning of a
" power often " — and their use illustrated by examples
in involution, square root, and cube root. But it
seems hardly fair to employ logarithms to solve
triangles by the usual formulae, until the universal
application of the latter have been demonstrated.
Again, a recent text-book introduces a chapter on the
mensuration of the circle by stating the value of -w,
and then showing how it can be measured in a
particular ease. Would it not be more correct to let
the class first grasp the fact that the ratio is constant
by actual measurements ? The mathematical value
could then be given for subsequent use. The first
method assumes that the pupil is already in possession
of the fundamental idea — an assumption by no means
justified in the case of evening students at this stage.
There seems to be very little reason for separating
students engaged in various trades in the early stages
of the work. A teacher can easily find examples to
suit Mining, Building, and Engineering students, and
should find but little difficulty in showing the practical
value of the subject. Instruction which does not
Subjects and methods of instruction 223
permit of this can hardly be called Mathematics ; it
should be regarded as an extra class for working
examples in the trade subject. Much good would
result in this, as in other cases, if the mathematical
and technical teachers were in consultation from
time to time during the year.
The importance and the apparent neglect of
Practical Plane and Solid Geometry have been
noticed in Chapter III. An elementary knowledge
of the subject has always been regarded as an
essential preparation for good progress in Machine
Drawing and Building Construction. While at one
time the main objects were to secure accuracy in
the drawing of plane figures, and to inculcate the
principles of projection, the syllabus has been con-
siderably altered in recent years. If one can judge
from the interpretation of writers of text-books, it
would appear that it now exercises a dual function.
On the one hand, the importance of projection is
kept in view ; on the other, the subject may be
regarded as an adjunct to Mathematics. This latter
opinion receives support from the fact that in the
Board of Education Syllabus of Practical Mathe-
matics it is stated in effect that the student is
supposed to be studying Practical Mathematics and
Geometry together. It seems doubtful whether, in
the smaller places, where teachers have, as a rule,
narrower qualifications, both aspects of the subject
will receive adequate treatment from the hands of
one man. The more mathematical side would no
doubt be admirably dealt with by the teacher of
Practical Mathematics ; projection would be more
fully and usefully developed by the teacher of
224 TECHNICAL EDUCATION IN EVENING SCHOOLS
Machine Drawing or Building Construction. With-
out laying any great stress on the point, the writer
ventures to suggest that this division of the subject
between two teachers may be worth consideration.
One of the effects of such "correlation" would be
that the student would learn three subjects where
there need be nothing to show him that he was
undertaking more than two. So long as the student
can use instruments and understand simple con-
structions, there seems to be no clear reason for
delaying Solid Geometry and Projection until after
Plane Geometry has been thoroughly mastered.
As to the needs of various types of students, it
may be said that those who do not aim at more
than an elementary knowledge of Machine Drawing,
Building Construction, etc., will find sufficient
material in the first stage of the syllabus of the
Board of Education. Students who wish to obtain
a more advanced knowledge of these subjects should
aim at securing a deeper knowledge of Practical
Geometry. A more extensive knowledge of the
development of surfaces and interpenetration of
solids is required for certain classes of joinery,
and for metal plate work. Such matters, however,
belong to the special drawing courses which are
arranged for men engaged in those trades.
Attention has already been called to the fact that
a knowledge of Physics and Chemistry is of very
great importance to the technical student. In the
absence of an elementary knowledge of Mechanics,
Heat, and Chemistry, very many points which
arise in the study of Applied Mechanics and
Steam, Mining and Building Construction, cannot be
SUBJECTS AND METHODS OF INSTRUCTION 225
understood. Teachers of these subjects must refcr
from time to time to " pure " science in dealing with
its applications, and many text-books contain a brief
account of the fundamental facts and principles. It
is sometimes asserted that the technical teacher can
be trusted to give all the instruction in these matters
that his pupils may require. But while recognising
that much will depend on the teacher, doubt may be
expressed as to whether this method is of any real
use. The idea that what is fundamental comes first
seems axiomatic. A technical subject is largely an
empirical subject ; it can rarely be developed in
logical order, and a single machine or process which
may be under consideration may involve two or
three fundamental principles. The preparation of
the gases of the mine, and subsequent demonstration
of their properties, would appeal to the student whose
mind contained some ideas as to chemical change,
and the nature of the substances, and who was
familiar with the terms and methods which would
have to be used during the lesson ; and the informa-
tion might be retained by a few students. But in
the latter case, would this information be part and
parcel of their mental equipment, connected with all
the other ideas on the chemistry and physics of
Coal Mining ? Even to the few students who under-
stood some of it at the time, would it not remain
more like a glimpse into an unknown world ? Does
the Engineering student who has no knowledge of
Heat or Chemistry ever really understand those parts
of the technical teaching which deal with the proper-
ties of steam, the chemistry of combustion and water
purification? And how many students of Building
226 TECHNICAL EDUCATION IN EVENING SCHOOLS
Construction, similarly ill-prepared, understand the
nature of the materials as expounded by the teacher,
or read in the text-book ?
It seems that the view that the theoretical explana-
tion can be left to the technical teacher is absolutely
at variance with a most important doctrine — the
doctrine of Apperception. A new idea is assimilated
only so far as it is able to associate itself with ideas
which are already arranged in orderly manner in the
mind of the learner. For the Mining teacher to
assert that the ventilating fan depends upon Newton's
first law of motion, and then to state that law, 1 is
more likely to give rise to blank astonishment than
anything else in a pupil who never heard of Newton,
is not quite sure of what a " law " is, and has only a
vague idea of what the word motion means. Even if
the statement of the law is understood, the student
has to remember a pair of isolated ideas, instead of one.
While a certain amount of information can be
imparted in a didactic manner, the knowledge is not
of the kind that is of real value. If the knowledge
which the student acquires in the technical classes
is to be of any use to him, it must be clear, definite,
organised knowledge, and there appears to be no
other way of attaining this end than to insist on
systematic instruction in the elements of Physics
and Chemistry, even for those who do not aspire to
occupy more than a minor position of responsibility
in their employment. So far as the writer knows,
there is no royal road open to them. 2
1 This is an actual example.
2 At the Engineering Conference mentioned in the first
chapter, Professor A. B. Kennedy stated that evening classes
SUBJECTS AND METHODS OF INSTRUCTION 227
If it is conceded that this instruction is necessary,
a question of interest arises as to who is to undertake
it — the science teacher or the technical teacher ?
Leaving out the well-qualified staffs of the larger
Technical Schools, there are few technical teachers
who care to deal with the scientific principles, and as
a general rule these should not be encouraged. In
the majority of cases the technical teacher is a man
who works at his trade during the day, and teaches
on two or three evenings a week. His scientific
knowledge probably has rusted by disuse, and it is
unlikely that he will have had any training in
experimental demonstration. The science teacher, on
the other hand, is nearly always a professional teacher,
regularly employed in lecture-room and laboratory,
and constantly exercised in manipulation.
However, he is not without his defects, and the
most serious is that his want of acquaintance with
the applications of Science may lead to his failing to
show the bearing of the subject on the occupations of
the class. This is a difficulty that is responsible for
no little criticism of technical education, and its
removal is a matter of the greatest importance. A
good deal towards this end could be accomplished
by co-operation between teachers of Pure Science
and teachers of Applied Science and Technology.
Mutual discussion of syllabuses would be of con-
siderable value in rendering the teaching of Chemistry
were injurious because the student learnt nothing but Engineer
ing, and the man who confined his attention to Engineering
subjects never made a good Engineer. Professor Barr referred
to those who had made great advances in Engineering practice,
and pointed out that " every one of these men had studied the
sciences on which true practice must be founded."
228 TECHNICAL EDUCATION IN EVENING SCHOOLS
and Physics less academic, and in fostering references
to underlying principles in the applied subject.
Further consideration of the equipment and training
of teachers must be postponed until Chapter IX.
In deciding what portions of Physics are required,
it is important to bear in mind that the branches
should be taught in rational order. Mechanics
-precedes Heat, Heat precedes Electricity. 1 This is
universally acknowledged and practised in day
schools, and is, in fact, dictated by the logical
connection between the subjects. It is not to be
understood, of course, that the whole science of
Mechanics is to be mastered, before Heat is begun.
But if it is proposed to study Heat, a certain amount
of knowledge of Mechanics is essential. For the
preparatory course suggested in Chapter II., the
latter subject may include density and specific
gravity; the simpler phenomena of hydrostatics.;
the barometer ; some idea of force and motion ;
energy and work ; and simple machines. The
work in Heat will involve explanations of the
construction and use of thermometers ; the main
facts connected with the expansion of solids, liquids,
and gases ; specific and latent heat treated in a
simple manner ; conduction and convection ; and
the mutual convertibility of heat and work. The
treatment throughout should be experimental, but
calculations should be carried out whenever these
are within the mathematical capacity of the student.
Much of the want of effectiveness in teaching these
subjects arises from touching a subject too lightly.
There is nothing for the student to bite, and ideas
i Chemistry should follow Heat and precede Electricity.
SUBJECTS AND METHODS OF INSTRUCTION 229
require to be fixed by working plenty of numerical
examples.
Such instruction would enable students to make
sound progress in the technical subjects, so far as
these can be carried in a two or three years'
course ; but it can hardly be considered enough for
those who propose to devote four or five years to
study, and who may in all likelihood proceed to the
Technical College. These will require a more exten-
sive knowledge of the Mechanics of Solids and
Fluids, Heat, Electricity, and Magnetism. As in
the elementary course, the view is held that the
treatment should be on the lines of systematic in-
struction in pure science, with frequent illustrations
from the daily occupations of the students.
In regard to Chemistry, also, the more elementary
part of it is better taught before the serious study of
technical subjects begins. If the student is intro-
duced to the subject by the usual experiments on
the rusting and tarnishing of metals, he will be led
to the composition and properties of air ; the pro-
perties of oxygen and the common oxides ; the
composition and properties of water, and its suita-
bility for industrial purposes ; hydrogen and its
properties ; and the common materials and pheno-
mena of every-day life. He will get some notions
as to what is meant by chemical change, and obtain
some acquaintance with the chief classes of inorganic
substances. Incidentally opportunities will occur to
deal with the best conditions for combustion and the
nature of the products in an ordinary furnace ; with
the principles of metallurgical operations ; with
matters connected with founding and forging ; with
230 TECHNICAL EDUCATION IN EVENING SCHOOLS
the necessity and means of preserving metal work ;
and many other subjects of direct interest to the
students. While they were insensibly being trained
in observation and methods of inquiry, they would
develop a keener interest in the things around them.
The question as to whether formulae and equations
should be introduced at this stage is not easy to
decide. The alternative syllabus in Chemistry of the
Board of Education in which formulae and equations
did not appear has frequently been recommended for
technical students on that account. Such a view,
however, ignores the prospect of the student's having
any desire to proceed further privately, or to read
technical literature. Writers of text-books and in
technical journals have no qualms of conscience as to
the use of formulae and equations, and so long as the
" chemist's shorthand " is employed so freely in all
the sources of information to which the student may
turn, it seems difficult to avoid the conclusion that
even an elementary study of Chemistry — to be
complete — should include some explanation of the
symbolic representation of composition and reaction.
For students who desire to extend their studies
over four or five years, further study would be
desirable. The question will again arise as to
whether highly specialised instruction or a more
scientific treatment is to be followed. While there
may be differences of opinion on this matter, it is
probable that the latter course would be more
suitable, especially if emphasis were laid upon those
facts and principles which were of the greatest
importance to the majority of the students. The
instruction might include some of the important
SUBJECTS AND METHODS OF INSTRUCTION 231
facts of physical chemistry; a fuller discussion
of combustion, especially in gaseous mixtures;
explosives; and a general study of the common
elements according to the periodic classification in
which, while the general properties of the groups
would be demonstrated, special attention would be
paid to those substances of industrial importance.
The time usually devoted to purely chemical
manufacturing processes — sulphuric acid, alkalis,
iodine, etc. — might be considerably curtailed. This
plan seems to have an advantage over that in which
Engineering students are recommended to join a class
in Metallurgy, for two reasons. The more extensive
study of the principles of Chemistry will be of great
value to him in after life, and the details of smelting
operations are of little interest to him unless he
happens to be employed in a Metallurgical Works.
Before closing the discussion on Physics and
Chemistry, it may be noted that in most cases the
former subject can be taught to students in any of
the trades considered without much difficulty, and
that the same plan can be followed in Chemistry
in the early stages. If, however, the latter subject
is to be highly specialised, . the students ought to
be dealt with separately. The determining factor
is the number of students from each trade who
require ^instruction, and it is always difficult in
evening work to avoid classes of mixed experience
and aims. Where it can be effected with economy,
the teacher's task may be lightened, and the educa-
tional progress of the students rendered more rapid,
by grouping those engaged in the same or similar
occupations.
232 TECHNICAL EDUCATION IN EVENING SCHOOLS
In considering instruction in Machine Drawing
and Building Construction there are several points
of interest. No satisfactory progress can be made
unless the students have had previous practice in
the use of instruments and understand simple
geometrical constructions. Where such prepara-
tory training has not been received, very slow
progress is made, and all preparatory courses
involve the study of Geometry. Granted that the
student is fairly adept in the use of instruments,
it is important to have clear notions as to the
object. Primarily the student requires to be taught
to "read" drawings rather than to "make" them,
in order that he may understand the drawings to
which he has to work in the shops, or those which
occur in his text-books and in technical journals.
In other words, the first object appears to be the
acquisition of facility in visualising a solid object
from its flat representation. This end can be best
attained by constantly associating the model or
actual object with the drawing. A freehand
dimensioned sketch should be made from the
student's own measurements, and the scale drawing
made from the sketch. In this way the student
obtains some idea of the proportions, and a clear
conception of the construction of the examples
drawn.
Incidentally, the student who is taught according
to the above method learns how to sketch in fair
proportion, obtains practice in accurate drawing,
becomes familiar with the materials used in con-
struction, and the form which must be adopted to
give the necessary strength or stiffness. These
SUBJECTS AND METHODS OF INSTRUCTION 233
observations will be far more real and permanent
than can be secured by didactic instruction in
construction.
In later stages of the work the use of models is
of less importance, though they may be useful for
demonstration. This does not mean, however, that
the well-nigh universal practice of " copying " flat
examples is correct at any period. But it seems
desirable that the student should begin to use his
observation and experience to execute simple
designs. Close observation and inquiry will thus
be stimulated, and the student will gain confidence,
and develop resource and initiative. He will learn
that while the proportions of many parts of con-
structive work must be determined by accurate
calculation, those of other parts are largely de-
pendent upon the judgment of the designer, and
he will be introduced to questions of economy,
which are so important in the present stress of
industrial competition.
There is, in general, far too much time devoted to
this subject in Evening Technical Schools, and much
of the work done in class might equally well be done
at home. A certain amount of facility in draughts-
manship is no doubt very useful, but to the majority
of students drawing is a means rather than an end,
and while many have to work to drawings, few are
required to make them. Sketching, however, is of
importance to all, both in actual work and in facili-
tating their progress in other subjects of instruction.
The usual method of copying diagrams from a book,
in which all the difficulties of representing a three-
dimensional object on a flat surface have been
234 TECHNICAL EDUCATION IN EVENING SCHOOLS
overcome — in what manner the student rarely learns
— does not seem to be satisfactory. Little is gained
in this way beyond a certain freedom in the use of
the pencil, and some practice in copying outline. To
sketch solid objects with any degree of accuracy
requires a knowledge of the principles of Model
Drawing, and this is best attained in the preparatory
courses of instruction indicated in Chapter II.
The somewhat sharp distinction which has been
drawn between the objects of the earlier and later
stages of instruction in Machine Drawing and
Building Construction appears to be equally appli-
cable to Applied Mechanics and Steam. At first the
student may be considered to be gaining familiarity
with the applications of mechanical principles, with
the properties of materials, and with the construction
and mode of action of common machines. The
object is, not to enable him to answer certain
typical questions at the end of the session, but
to excite curiosity and interest in the tools,
machinery, and methods employed in the various
trades. Meanwhile, the student is accumulating
experience as to the why and wherefore of par-
ticular structural forms, mechanisms, methods, which
provide material for " designing," should he have the
capacity and the desire to proceed to the higher
branches of these subjects. Difficulties may occur
sometimes in selecting examples which appeal with
equal force to all the students, who may be drawn
from various industries; and slavish adherence to
certain text-books may lead in some cases to much
discouragement. A book which confined itself almost
entirely to a detailed consideration of Marine Engines
SUBJECTS AND METHODS OF INSTRUCTION 235
might be admirable for students employed in a
Marine Engineering Establishment, and quite un-
suitable for others whose experience lay in a totally
different class of work. To be effective, teaching
cannot rely entirely on the work done in the class-
room, but must stimulate reaction between the
student and his environment.
Students in some industries may be said to require
only certain portions of Applied Mechanics. Thus,
for Building students a knowledge of Statics is of
chief importance, while Mining students are more
directly concerned with Pumping, Haulage, and the
Transmission of Power. Neither class will be much
interested in the principles of mechanism — in the
theory of the various contrivances for communicating
motion. How far special desires of this character
should be humoured is probably an open question, and
steps in this direction, however desirable, will always
be limited by considerations of economy. It may be
noted, moreover, that while a syllabus may appear
much wider than a casual glance at immediate require-
ments may indicate to be necessary, it may be none too
wide to ensure satisfactory progress in another subject
which may have to be studied subsequently. This is
illustrated by the case of the student who desires to
obtain some knowledge of Steam, Gas, and Oil
Engines. Unless the teacher of the latter subject is
going out of his way to explain all sorts of mechanical
contrivances, such a student can omit very little of
the first stage of the Board of Education Syllabus in
Applied Mechanics. It would be well if every
student, no matter what industry he may be engaged
in, so long as it involves the use of machinery, were
236 TECHNICAL EDUCATION IN EVENING- SCHOOLS
to aim at securing an elementary knowledge of both
these subjects, before devoting his attention to a
special section.
Wherever laboratories are available, it is most
important that practical work should be done by the
students in these subjects. Such work takes up a
considerable amount of time, but this cannot be
weighed against the benefits that accrue from a well-
organised series of experiments. The closest possible
connection between the lecture and laboratory work
is desirable. It is in the laboratory that the student
obtains at first hand a knowledge of the properties of
materials, and the capability of machines ; where he
learns to adopt the habit of inquiry, and develops
resource and initiative. And in Applied Mechanics,
at any rate, the theoretical lesson is best devoted to a
discussion, consolidation, and extension of the results
obtained by the students in the laboratory.
The question as to whether the theoretical instruc-
tion should be based upon the student's work in the
laboratory, or vice versd, is not, in the early stages, a
mere matter of opinion. If the latter is adopted,
there is less value in the training, and a tendency to
concentrate attention on obtaining a numerical result.
For an elementary student to be told to " verify " an
important "law" seems likely to give rise to a mis-
apprehension as to the value of his own work, and to
discredit the work of the great investigators who have
preceded him. The whole attitude savours of down-
right impertinence. On the other hand, if the student
has the subject presented to him as a series of
problems, if he is encouraged to devise experiments
for their solution with the simplest apparatus, he is
SUBJECTS AND METHODS OF INSTRUCTION 237
developing habits which will be of the greatest value
to him in after life. As Sir Philip Magnus says : x
"No education is complete, however elementary
soever it may be, which does not show us the
methods by which knowledge has been created, and
give us some training on their use."
The most important point to note in connection
with Coal Mining is the number of subjects of both
pure and applied science which are involved in the
study. The Mining teacher has to refer from time to
time to matters which are usually only fully discussed
under the titles of Theoretical Mechanics of Solids
and Fluids, Heat, Chemistry, Electricity, Geology,
Applied Mechanics, and Steam. In addition, he
must deal with methods of working coal, and with
the precautions which must be observed in accordance
with the Coal Mines Regulation Act. The students
have only received, except in rare instances, an
elementary school education. The teachers are
practical men, who in very few cases have any
special training in Engineering, and still less in
fundamental scientific subjects. It is obvious that
one man cannot give satisfactory instruction in such
a composite subject. While admirably qualified, as a
rule, to discuss methods of working, they have neither
the time nor the training to give instruction in the
subsidiary subjects which are essential to an intelligent
understanding of the manifold operations involved in
the economical production of Coal. The teaching,
except in regard to the details of "getting coal,"
must be didactic; the knowledge largely empirical.
Bearing in mind the nature of the subject, the
1 " Industrial Education," p. 121.
238 TECHNICAL EDUCATION IN EVENING SCHOOLS
qualifications of the teachers, and the general
state of preparation of the students, it may be
stated, with no little emphasis, that Technical Educa-
tion for men who are to occupy responsible positions
in this industry must provide for the widest possible
scientific basis.
The necessity for a colliery manager or undcr-
manager to possess a certificate of competency
provides a stimulus that cannot be found in any
other industry ; but it is to be feared that this has
not always been of a wholesome character. It is
almost unavoidable that where an examination is
regarded as an end rather than a means, there
should be developed a desire to find a "royal road,"
and the educational value of study must suffer in
consequence. This must be more serious when, as
in the present case, the examiners are not necessarily
in close touch with educational institutions, and are
rarely acquainted with improvements in educational
methods.
While the Home Office Examinations have done
much to raise the standard of theoretical knowledge
of colliery managers, their function in regard to
Technical Education needs to be carefully defined.
The test is a minimum test. Its aim is to secure
that the men in charge of collieries shall be acquainted
with present methods of working, and with the
provisions of the Acts which have been passed to
secure the safety of the men. The aim of Technical
Education, on the other hand, is to secure that men
who may become colliery managers shall possess
such a knowledge of the principles underlying their
own and cognate industries that they may be able
SUBJECTS AND METHODS OF INSTRUCTION 239
not only to carry out their duties in a satisfactory
manner, but also to take advantage of new inventions
and discoveries, and meet the ever-varying needs for
new machines and new methods as they arise. The
Home Office Examination is an incident in the
Mining student's career — essential, it is true, but
imposing no upper limit.
The most satisfactory results will be obtained,
therefore, where the Mining teacher devotes himself
to that part of the subject of which he has special
knowledge, while the subsidiary but not less important
subjects are taught by those who are more highly
qualified to deal with them. The instruction may
include the elements of Geology, with special reference
to the carboniferous formation, and the consideration
in detail of the operations of sinking, laying out, and
working collieries. Detailed descriptions of plant
will naturally be deferred until the student has a
sufficient knowledge of Mechanics to appreciate the
principles involved. As most of the students are
engaged at the coal-face, and only indirectly con-
cerned with machinery, this arrangement possesses a
decided educational advantage. Moreover, problems
of economy will be more readily grasped by the
student who is older, and has a more extensive
mind-content.
The question as to whether workshop instruction
should be given in Evening Technical Schools is of
importance, if only on account of the popular notion
that the provision of a workshop makes any school
into a technical school. Dealing first with Engineer-
ing workshops, it may be noted that they were
originally introduced to enable Engineering subjects
240 TECHNICAL EDUCATION IN EVENING SCHOOLS
to be illustrated to boys fresh from school who had no
previous workshop experience. The students were
shown how to forge, chip, file, and how to make
patterns. In the time at their disposal, it is obvious
that only a general knowledge of tools, materials and
processes, and no great skill, could be obtained.
When these workshops are thrown open to evening
students, the avowed object in a number of cases is
to supplement the somewhat meagre experience
which falls to the lot of most apprentices owing to
the extensive division of labour that obtains in the
industry. The instruction varies from that indicated
above as being given to day students, to the
construction of a small engine or machine tool.
If the tendency in industry is to reduce the need
for workmen of all-round skill, it is doubtful whether
a mere repetition of the student's daily work falls
within the scope of technical instruction at all. So
far as skilled workmen are required, it seems reason-
able to suppose that the managers of works will
themselves see that the supply does not sink below
the demand. The nature of a man's work is generally
at their discretion, and they can, if they feel the
necessity, give him a far more satisfactory training of
this sort than any technical school workshop.
But if the need of skilled workmen has decreased,
the demand for more exact knowledge of materials,
processes, and tools on the part of foremen has
increased, and the special syllabuses in Chapter IV.
indicate a tendency on the part of technical schools
to supply instruction suitable for men of this type.
The Leicester Syllabus (p. 90), in particular, seems
to deal with knowledge that a man might spend
SUBJECTS AND METHODS OF INSTRUCTION 24!
years in the shops without acquiring ; and instruction
of this sort, combined with a moderate knowledge of
the scientific principles underlying the industry as a
whole, would probably be of great value to those on
whom the responsibility of controlling the workshop
will devolve.
The next question that arises is, Can such instruction
be adequately illustrated in school workshops, and if
so, is this essential? To these questions it is not
easy to give an answer. The writer, without laying
any great stress on his opinion, would say " Yes " to
the first and " No " to the second. The chief difficulty
would probably be met in the small amount of time
which the evening student can devote to the subject,
and the fact that the execution of work in metal
cannot be hurried. Where workshops exist it might
be possible to arrange a series of exercises to illustrate
the instruction, and in the absence of technical school
workshops, useful demonstrations in the works — with
the consent of the employers — might be given. The
object would not be the acquirement of skill, but that
wide knowledge which a man should have if he is to
exercise control over a number of men engaged on
different kinds of work.
It would be unwise to curtail the amount of time
which those who aim at more important positions in
the industry can spend upon theoretical subjects, for
the sake of the somewhat doubtful advantage of a
course in the Evening Technical School workshop,
and no provision will be made for this in the major
courses of instruction to be described later.
In regard to Building students, the same considera-
tions will apply, and specific instruction in the " trade"
Q
242 TECHNICAL EDUCATION tN EVENING SCHOOLS
subject, with workshop practice where desirable, will
be included only in the minor courses.
An important point in regard to the subjects dis-
cussed is their dependence upon one another. For
satisfactory educational progress, it is necessary that
they should be arranged in a rational order. Thus,
in the case of steam and gas engines, the student will
find far fewer difficulties if he has some previous know-
ledge of Heat, Chemistry, and Applied Mechanics.
Chemistry itself is not an easy subject if the student
has no preliminary knowledge of Heat, and Applied
Mechanics is more readily appreciated by a student
who has acquired clear conceptions of mechanical
principles through a study of Experimental Mechanics.
Finally, little progress can be made in any subject
without an adequate knowledge of Mathematics and
Geometry.
Again, Applied Mechanics, Steam, and Mining
require that the student shall be able to understand
drawings of machinery, and Machine Drawing presup-
poses a knowledge of at least the simple geometrical
constructions and the elements of projection.
The various branches of Physics can be arranged in
rational order among themselves. Mechanics can be
taught successfully, up to a certain stage, to students
who have a sufficient knowledge of Mathematics and
Geometry, without the slightest reference to Heat or
Electricity. The same cannot be said of Heat, which
involves ideas of mass and density from the beginning ;
while Electricity and Magnetism is still more a
derived subject, requiring, if clear concepts are to
be obtained, a knowledge of Mechanics, Heat, and
Chemistry.
SUBJECTS AND METHODS OF INSTRUCTION 243
If the subjects which have been discussed in this
chapter are arranged in logical sequence, we get the
order : Mathematics and Geometry, Mechanics, Heat,
Chemistry, Electricity and Magnetism. Applied
Mechanics comes level with Heat, and Steam level
with Electricity and Magnetism. Machine Drawing
may follow Geometry and precede Applied Mechanics,
while Machine Design is really Applied Mechanics
and Steam in a higher stage of development. From
this point of view Mining is wider than any of the
others, being the application of Engineering to the
getting of minerals, and involving, therefore, a
knowledge of Geology.
Of course, all this is perfectly well known, and it
is an indisputable fact that progress is easier and
sounder when the logical order of studies is obeyed.
That the advantages of a proper arrangement of
studies has been so completely ignored in Evening
Technical Schools in the past is a matter of aston-
ishment. Some parts of a subject can be taught
as though it were completely independent ; but ideas
can never be so clear, the knowledge can never be
so precise, as when due regard is paid to logical
order. There can be no comparison between the
rate of progress and the knowledge acquired by a
first year student in Steam who has received
appropriate preliminary training, and by a student
who has not. Mathematics alone is of no avail ;
the mind-content of the pupil should be such as
will render the assimilation of new ideas rapid and
sure, and this mind-content can only be produced
by a previous study of Physics and Applied
Mechanics, accompanied by Machine Drawing.
244 TECHNICAL EDUCATION IN EVENING SCHOOLS
If in addition to the rational order of subjects
studied in successive years there could be judicious
. correlation between subjects studied concurrently,
the capacity of students would be greatly increased.
The best students naturally perform this correlation
for themselves; but if there were an intelligent
understanding between the teachers of different
subjects — for which a plea has already been
advanced — students of lesser calibre would find
many of their difficulties removed. This is not
providing a "lift" instead of a "ladder," but
making the most of the material at hand. Evening
students, as a whole, are little less capable than day
students ; they labour, however, under heavy dis-
advantages, and their attendance for study after
a hard day's work shows that they possess not a
few of the qualities that make for success in life.
Just as the capacity of the electric field increases with
the dielectric strength of the medium, so does the
capacity of the Evening Technical School increase
with the " educational atmosphere " that pervades the
instruction. The students acquire knowledge and
skill more rapidly at the same pressure.
CHAPTER VIIL
COURSES OF INSTRUCTION
If students are to reap the full advantages of
systematic courses of instruction, there must be
some definite standard of admission. In towns —
especially in Engineering classes — there is an increas-
ing number of students who have been for three or
four years at a Higher Elementary School, or for
two or three years at a Secondary School. If to
this fact is added the doubtful value of technical
instruction in the case of students under sixteen or
seventeen years of age, it does not seem extravagant
to demand from all students the standard of attain-
ment suggested in the preparatory course indicated
in Chapter II., and more fully described as regards
Physics and Chemistry in the last chapter. The
following courses therefore involve the assumption
that the students have such a knowledge of Mathe-
matics and Geometry, Physics and Chemistry, on
their admission to the Evening Technical School.
It must be understood that these courses are not
the only possible ones. Others could be arranged
without departing from the logical order of subjects,
2AA
246 TECHNICAL EDUCATION IN EVENING SCHOOLS
and experience alone can determine which is the
most suitable for any particular conditions. They
are to be regarded simply as illustrations of the way
in which educationally sound, systematic, and pro-
gressive courses can be drawn up so as to involve
no more time than the evening student can usually
devote to study.
(a) Mechanical Engineering.
We may consider first the lower grade, in which
the whole training has to be obtained in evening
classes. The student will have left school at
fourteen to fifteen years of age, and have spent
two years in evening continuation or preparatory
classes. The nature of the instruction required will
be as follows :
(i.) Mechanical Drawing, so far as it is
necessary to enable him to read working
drawings.
(ii.) Applied Mechanics and Steam, to enable
him to understand the machinery employed
in the shops.
(Hi.) Mathematics, to enable him to follow the
instruction under (ii.), perform the ordinary
calculations of the workshop, and read
the literature of his own of the branch
trade.
COURSES OF INSTRUCTION
247
(iv.) Specific instruction in the principles more
directly underlying his own branch of the
trade, accompanied, where possible, by
workshop illustration.
These subjects should cover three or four years,
and should not require more than three or four
nights a week. The following arrangement is
suggested :
First Year
Second Year
Third Year
Mathematics and
Geometry
Machine Drawing
Applied Mechan-
ics (Theo. and
Pract.)
Mathematics and
Geometry
Machine Drawing
Special
Applied Mechan-
ics (Theo. and
Pract.)
Steam (Theo. and
Pract.)
Special
If the work of the student involves the use of
electrical machinery, the fourth and later years
can be devoted to Electricity and Magnetism, and
Technical Electricity. The special subject will be
fitting and turning, forge work, pattern-making,
foundry work, or boiler work ; and the instruction
in Machine Drawing should have regard to the
nature of the industry in which the students are
engaged. At the end of the third year, or, if a
student is weak in one or two subjects, the fourth
year, he should be able to pass the examination 1
1 The reference to examinations on this and the following
pages is merely for the purpose of indicating the general
standard of work at various stages.
248 TECHNICAL EDUCATION IN EVENING SCHOOLS
in the ordinary grade of Mechanical Engineering
under the City and Guilds of London Institute,
and he should possess the Board of Education
Certificates in the first stage of Practical Mathe-
matics, Applied Mechanics, Steam, Geometry; and
in the second stage, of Machine Drawing. Any
further study should be accompanied by a corre-
sponding strengthening of the general foundation.
This course is probably most nearly followed at
Salford. It differs . mainly from that course in
substituting Steam for the second stage of
Geometry ; in the provision of the preparatory
course in which the student obtains sufficient
knowledge of Experimental Mechanics and Heat
to render his path easier in Applied Mechanics
and Steam ; and sufficient knowledge of Chemistry
to enable him to get clear notions of combustion
and the preservation of materials.
Dealing now with the higher grade, it may be
observed that the difficulties are more serious. The
instruction required covers a wide field, time is
limited, and the student is not anxious to devote
much of it to subjects which often do not appear
to him to have direct application to his work.
At the same time, it has been pointed out that
specialisation on too narrow a basis is unsound
educationally, and that continuity of the evening
and day curricula should be kept in view. What,
then, is the proportion of time that each subject
should receive in order to preserve a balance of
studies ? The following table may help to solve the
question. It indicates the number of hours which
a day student devotes in the year to each subject,

Notwithstanding the fact that considerable differ-
ences are apparent, there is still much upon which
the different schools agree. Departures from the
mean are easily explained. Thus the Bradford
course is distinctly framed to shorten the period
of apprenticeship, and the course all through
contains a preponderance of workshop practice.
Parenthetically, the fact that strictly engineering
subjects are omitted until nearly 700 hours have
been spent in the workshops is not an unworthy
argument in favour of the school-works-college view.
The only school which does not include Chemistry
250 TECHNICAL EDUCATION IN EVENING SCHOOLS
is that at East London; If a mean is taken of all
the courses, a course will be obtained to which few
objections could be raised.
The problem, then, is to determine an arrange-
ment of subjects in a rational order which shall
occupy not more than three evenings a week, and
cover approximately the same ground as a day
student does in an average course of instruction
corresponding, to those which have been set out.
The following table is the result of many attempts
to attain this object without departing from the
syllabuses and hours of instruction that obtain in
the majority of schools :

The standard aimed at in each subject may be briefly
stated, and one or two other matters discussed.
The Mathematics in the first year would cover the
first stage of the " practical " syllabus, with additional
trigonometry. Geometry would have its dual
character recognised by treating Plane Geometry
and Graphics in the hour and a half following the
Mathematical lesson, from which it would frequently
be inseparable, and associating the projection of
solids with Machine Drawing. General Physics
includes dynamics and properties of matter. In this
way it is believed the well-prepared student would
be able, at the end of his first year, to take the second
stage examinations in Theoretical Mechanics, solids
and fluids, and in Practical Plane and Solid Geo-
metry, with the first stage examinations in Practical
Mathematics and Machine Drawing.
The second stage examination in most subjects is
usually considered to represent the test for at least
two years' work. This is true enough in the case of
an ill-prepared student taking a single subject ; but it
it does not apply to students who have a fair general
252 TECHNICAL EDUCATION IN EVENING SCHOOLS
preliminary training, and whose studies are arranged
in logical sequence, and with intelligent grouping.
The second year work leads to Stage* 2 of
Practical Mathematics, Machine Drawing, and
Heat ; the third to Stage 2 or 3 in Practical
Mathematics, Stage 2 in Applied Mechanics and
Chemistry ; and the fourth year to Stage 2 in
Electricity and Magnetism and Steam, and Stage 1
in Metallurgy. The latter subject might well be
replaced by a course in Engineering Chemistry.
Of course, it is easy to criticise this scheme. Thus,
in some courses which have been considered, two
years are spent in the study of the elementary stage
of Steam. For them, however, no preliminary
standard is exacted, nor do they include a year's
study of Heat, as the one above does. Again, none
of the day Colleges teach Steam in the first year ; it
may be asked : Why, therefore, do it in evening classes,
which are supposed to correspond ? The course is a
compromise. The student may not proceed to a day
College. The introduction of Steam at that point is
desirable in order to give a certain amount of com-
pleteness to the curriculum ; and the main defect
which required remedy was the lack of breadth of
studies in existing courses. The amount of time —
about seven and a half hours a week — may appear
excessive. On the other hand, the amount of time
devoted to drawing or laboratory work in successive
years is five and a half, four, three, and four and a
half. Drawing is not exacting, nor is laboratory
work, while it facilitates the attainment of clear
notions, and diminishes the number of numerical
examples that need to be worked. Still another
COURSES OF INSTRUCTION 253
complaint — and probably a very general one — might
be that Chemistry has been too generously treated.
The subject is of much more importance than is usually
admitted, and this importance is on the increase. 1
Moreover, it takes longer to permeate the average
student than any other subject, and for this reason
alone demands all the time that can be given to it.
The course provides a basis for specialisation, and
the duration of four years has another significance.
While the usual duration of apprenticeship is from
the age of entry to twenty-one, the shortest period
for a school-works-college pupil is generally fixed at
four years. This coincides exactly with the course
proposed, while the scope of studies enables the
student to commence on the second year course on
entering College.
Lest the plea of too much pure and too little applied
science should be raised, the suggested curriculum
may be compared with that for apprentices in the
Royal Dockyards. The number of marks attached
to each subject is an indication of its importance.

There is ample justification for the inclusion of
Physics and Chemistry. The standard of admission
is Arithmetic (except cube root), Algebra, including
simultaneous and quadratic equations, Euclid I. to
III., and the usual English subjects; the age is
fourteen to sixteen years. This is not very different
from that proposed for evening schools in this book :
in Mathematics it is more extensive, but neither
Physics nor Chemistry is required. It will be noted
that all apprentices attempt this course, and some
are weeded out at the half-yearly examinations.
There is no attempt to supply in the school the
specific instruction in the several branches. An
apprentice is attached to an instructor, who is a
skilled workman specially selected by the superior
COURSES OF INSTRUCTION
255
officers of the dockyard for this purpose, and who
receives two shillings a week extra in consequence.
While this is an infinitely better arrangement than
any that exists in private shops, it is open to question
whether it is equal to specific instruction (say) on
the lines of the Leicester Syllabus (p. 90). Of course,
an apprentice can attend evening classes after he has
left the dockyard school.
The system has turned out numbers of men who
now hold the highest professional positions in the
country — such as the higher positions in the
Admiralty, the Marine Department of the Board
of Trade, Lloyd's Registration Society, and many
private shipbuilding and engineering firms. 1

The only courses for the minor positions under this
head appear to have been drawn up for those engaged
in wiring. There must, however, be a considerable
number of men who aim at becoming shop foremen,
and for whom the major courses are too ambitious.

The scope of each subject will be sufficiently
apparent from what has been already said.
The major course in Electrical Engineering need
differ in no important respect from that for Mechanical
Engineering. The electrical engineer is quite as
much concerned with the properties of materials, the
methods of mathematics and geometry, the funda-
mental principles of physics, the theory of mechanisms,
as the mechanical engineer, and the first year courses
of instruction at nearly all the day Colleges are
common to both.

The main sub-divisions of the Building trade for
which minor courses are required are Carpentry and
Joinery, Bricklaying, Masonry, and Plumbing. As
plasterers' and painters' and decorators' work are in
part Art crafts, they are outside the scope of this
book.
For carpenters and joiners, the following three years'
course is suggested :

Second Year

This differs from the course at St. Helens in the
substitution of Applied Mechanics for Theoretical
Mechanics, and in prescribing two years for Building
Construction. The principal reason for preferring the
applied subject is its bearing upon 'machinery which
is so largely used in the trade. The Special Drawing
in the third year would include projective geometry
and setting-out. If machinery were largely used in
the neighbourhood, a further course in Applied
Mechanics would be desirable in that year.

The special aim in each of these schemes is to
provide a progressive and educationally sound course
of instruction leading up to the Honours Examination
of the City and Guilds of London Institute. Those
portions of the syllabuses which deal more especially
with underlying principles are removed, and the
appropriate science subject substituted. This leaves
the trade teacher more time to devote to his own
special part of the subject. Where a suitable syllabus
does not exist, a special course has been indicated.
The City and Guilds have for many years required
students to possess certificates in certain subjects of
science before the full technological certificates were
granted. Unfortunately, students have often taken
the Honours Certificate in the trade subject first, and
then cast about for the easiest subjects which would
COURSES OF INSTRUCTION 259
give them the full qualification. In this way not
only has the rational order of study been frequently
reversed, but owing to want of system in the organisa-
tion of schools, an unhappy choice has been made
in the science subject. The introduction of a pre-
liminary grade in certain subjects has obviated this
difficulty to some extent, and though exception
might be taken to the standard of the examination
in particular cases, the principle cannot be too highly
commended.
Major courses in Building are probably only
required in the larger towns. Those who require
them are Architects' pupils and others who aspire to
become master-builders on a fairly large scale. As
the courses given on pages 137-40 differ considerably
from one another, an attempt has been made to
combine the good features of all. In view of the
fact that so few Colleges arrange day courses for this
trade, no attempt has been made to fit it in with
any day course.

(d) Coal Mining.
A glance at the courses on pages 148-9 will show
that considerable doubt exists as to what should or
should not be included in a curriculum adapted to this
industry. The present aim of all Mining classes is
to prepare the student for the first and second class
colliery manager's certificates. The raison d"itre of
such certificates is to secure that collieries shall not
be placed in charge of incompetent men — to secure
that they shall be managed by men whose knowledge
of the Coal Mines Regulation Act, and the usual
method of working in the district, shall ensure that
the danger to life and limb shall be the least possible.
These qualifications are so easily obtained by men

whose length of experience compensates for deficien-
cies of early education, that they do not command
the respect they should from colliery agents.

The aim here is to give the student such a
grinding in scientific principles as will ensure his
ability to understand his own subject to the extent
that his position in the industry demands. The
minor courses would in all probability be held
in smaller places, where laboratory work could
not be undertaken. In such circumstances, more
time would be given to the working of numerical
exercises. The necessity of the instruction in
Mining being accompanied by instruction in
Drawing and Sketching is based upon the writer's
experience of Mining classes, and it receives strong
support from Professor le Neve Foster's Report on
the examination in the Principles of Mining for
1903. 1 The instruction in Mining would in all cases
include the Geology necessary.

Without seeking to inquire why the Cardiff scheme
leaves out Mathematics and Physics, and includes a
considerable amount of Chemistry, it will be profit-
able to suggest a less ambitious course for evening
classes, which involves no previous knowledge beyond
that of the Seventh Standard of an elementary
school, and which, by involving attendance on only
two nights a week, will be more convenient for a
greater number of students.

siderable importance. It is not possible to say what
proportion of Building Construction students receive
instruction in the appropriate trade subject, or vice
versd, but as a rule, classes in Building Construction
are composed chiefly of carpenters and joiners. The
number of schools in which Building Construction
was taught in 1902-3 was 447, and grant was paid on
11,470 students, which is probably not more than
60 per cent, or 70 per cent, of the number under
276 TECHNICAL EDUCATION IN EVENING SCHOOLS
instruction. In the same year the number of students
in registered classes in Carpentry and Joinery was
3,536, so that if, as has been suggested, most Building
students require special instruction, an increase in the
number of teachers of Technology is necessary before
systematic courses for this industry could be very
greatly extended. It may be useful to give the
corresponding figures for the other branches of the
trade :
Number of students under instruction
in Plumbing .... 3,253
Number of students under instruction
in Brickwork - 864
Number of students under instruction
in Masonry - 623
In regard to Builders' Quantities and Iron and
Steel Manufacture, the supply is probably more
nearly equal to the demand ; but there must be a
considerable number of classes in Mine Surveying
taught by men who are not registered under the
Institute.
Having shown the necessity for an increase in the
number of teachers of certain subjects of Science and
Technology, we may next proceed to consider methods
of obtaining them. The institution of systematic
courses of instruction would in time produce a large
number of men possessing the requisite general and
special knowledge. Much might be done immediately
if the local authorities were to establish central classes
in the more important subjects, and were to offer
special facilities to students to attend them. Those
SOME SPECIAL PROBLEMS 2;7
who completed the course and passed the examination
might be reimbursed their fees and travelling expenses.
Such a scheme has greatly increased the supply of
manual instructors. If care were taken in selecting
students of good general education and some
aptitude for teaching, and if these classes were held
twice a week for a year or two, the whole complexion
of affairs would be altered.
In order that proper correlation may exist between
subjects, it is often desirable that one teacher should
be responsible for instruction in more than one
subject. In the case of subjects under separate
teachers, correlation may be effected if each teacher
has some knowledge of the other man's subject. To
secure this, teachers of Mathematics might be
encouraged to qualify in Geometry; teachers of
Building Construction in Carpentry and Joinery, or
Brickwork and Masonry, and Geometry ; teachers of
Machine Drawing in Applied Mechanics, Steam,
Practical Geometry, and Practical Mathematics ;
teachers of Mining in Practical Mathematics, Applied
Mechanics, Steam, and Geology. Some instruction
in Sketching on the blackboard would be useful for
all. In time there would be a well-qualified body of
local teachers, who are generally preferable to the
itinerant teachers. The latter are rarely in close
touch with the students, still less with local employers
and local industries. If the travelling teacher is to
be a success in anything beyond pioneer work, he
must be a man of exceptional ability; and it is
fortunate that such men are occasionally to be found.
The difficulties of securing the services of a teacher
of technology in smaller and somewhat isolated towns
278 TECHNICAL EDUCATION IN EVENING SCHOOLS
might be solved in another way. A local employer
might be willing to find suitable employment for
such a man who could undertake to give instruction
on two or three evenings a week. A case is known
to the writer in which an offer of this sort was made,
and an extension of the idea will be suggested later.
Before leaving the question of improvement in the
supply and qualification of teachers, reference may
be made to the academic character of much of
the instruction in Chemistry and Physics. These
subjects are generally in the hands of teachers who
are graduates, and who rely on their University
training as their qualification for giving instruction.
So far as the teaching of Chemistry and Physics as
Chemistry and Physics is concerned, the qualification
is admirable. But in the greater number of Evening
Technical Schools these subjects are only subsidiary
subjects in a course, and require to be largely
illustrated by reference to the industry in which the
student is engaged. It is intensely disappointing to
an evening student who has yielded to advice, and
joined a class in one of these subjects, to find that a
whole session's work leaves him no whit the wiser as
to why the advice was given to him. The series of
lessons may have afforded many opportunities for
explaining the theory of operations which would
otherwise be obscure to the Engineering, Mining, or
Building students attending. Yet such opportunities
may be neglected owing to the teacher's want of
familiarity with the applications of the sciences of
which he has mastered the theory.
The difficulty could be partly overcome by the
co-operation of the scientific and technical teachers.
SOME SPECIAL PROBLEMS 279
The teacher of pure science can easily ascertain what
is required of him by consultation with the teachers
of Engineering, Mining, and Building. Much profit,
moreover, would result if teachers of Physics and
Chemistry were to read the books used by their
students in Applied Science. Many hints in regard
to the application of Physics could be obtained from
books on Applied Mechanics and Steam, and in
regard to the applications of Chemistry, 1 from books
on Mining, and the chapters on " Materials " in books
on Applied Mechanics and Building Construction.
The references to methods of teaching which have
occurred from time to time in previous chapters will
have paved the way in some measure for a discussion
of the next problem : The training of teachers for the
special work of the Evening Technical School. The
writer is fully prepared to be faced with the state-
ments that such training is neither necessary nor
practicable. An argument which might be raised is
that the students in evening classes have reached
" the age and standard at which the scholar becomes
a student," and " acquires rather than receives."
And from analogy with University Colleges and
similar institutions, it might be urged that under
these circumstances the artifices of the teacher are
of less importance, since the students are old enough
and sufficiently far advanced to rely on their own
resources. While denying most emphatically that
the " lecturing " of the University professor is
1 Further information can be obtained from Blount and
Bloxam's " Chemistry for Engineers and Manufacturers,"
Phillips' " Engineering Chemistry," and Sexton's " Chemistry
of the Materials of Engineering."
280 TECHNICAL EDUCATION IN EVENING SCHOOLS
necessarily conducted according to educational
principles — though in individual instances th)s may
be the case — it will be profitable to consider now far
the assumptions as to age and standard are justified.
Out of 657,000 students under instruction itj all kinds
of evening schools during the session 1903-3, 22 per
cent, were between twelve and fifteen years of age,
S3 per cent, were between fifteen and twenty-one,
and 25 per cent, were over 21. 1 Thus about half the
students in evening schools are not al/ove the age of
the pupils at secondary schools, the l/mits of age in
which may be taken as eight to eighteen years. Now,
in the case of the Universities it is generally admitted
that the younger students, who are never less than
sixteen, find the greatest difficulties in following
lectures. In this connection the evidence of Professor
Fleming is important. 2 These difficulties must be
due in great measure to immaturity of mind; the
idea that it may be due to the sudden transition
from " teaching " to " lecturing " is hardly borne out
when it is recalled that in the higher forms of
secondary schools the student is left more and more
to his own resources.
Consider next the standard of the work in Evening
Technical Schools. In the majority of cases the
student is introduced to the subject, and it is at the
initial stage where the greatest difficulties occur,
and where it is of the greatest importance that
accurate conceptions shall be formed. Once a
student has obtained preliminary notions, his
progress is more rapid ; he can rely more upon
1 Report of the Board of Education for 1903-4, p. 61.
2 See page 17.
SOME SPECIAL PROBLEMS 28 1
himself, and requires the services of a teacher to a
smaller extent.
There is still another argument in favour of more
careful attention to method. The evening student
can only devote from one-fourth to one-fifth of
the time to study that can be afforded by those who
attend the day College; it is undesirable that he
should suffer the disadvantage which must ensue if
he follows a narrower curriculum ; and if good
progress is to be made, this demands all the skill
that a good teacher can bring to bear upon the
instruction.
If we agree, then, that training can improve
methods of teaching, and that the age, standard,
and circumstances of evening students render it
essential that no effort should be spared in
securing efficiency of instruction, it is important
to consider how this may be attained. It will
be convenient to consider those who are not
professional teachers and those who are pro-
fessional teachers separately. In the first class are
to be found men of every type, from the man with
a genius for teaching, a master of his subject and
the method of imparting it, whom no training could
improve, to the man who, having acquired a limited
knowledge of a subject, is diligently trying to impart
it to others, but failing from want of general culture,
and conception of what teaching really means.
If the student is to follow courses of instruction,
these differences will lead to his greater progress in
some subjects than in others, and, it is to be feared,
would seriously affect his regularity of attendance
and reduce the educational advantages to be derived
282 TECHNICAL EDUCATION IN EVENING SCHOOLS
from systematic instruction. To remove these differ-
ences, the teachers might be encouraged to attend a
course of lessons on the object, scope, and methods
of Technical Education in evening schools, and on
the method of presenting and illustrating a subject
to a class, with some elementary explanation of the
way in which a student acquires knowledge and skill.
If the instruction in these matters was treated prac-
tically, and adapted to the capacity of those for whom
it was intended, it would be of great value in raising
the efficiency of their teaching. As to the encour-
agement to be offered, the local authorities might
give preference in appointment and in salaries to
those who availed themselves of the opportunities
for professional study thus afforded.
As practical men are apt to doubt the efficacy of
method, and the necessity of such training, it may be
useful to give an example or two of what has been
done in this matter. A course of instruction for
teachers of Coal Mining has been arranged at
University College, Sheffield. It consists of two
classes on Saturdays, from 4.30 to 6 p.m., and
6.30 to 8 p.m., as follows :
(a) "Criticism Lessons," with practice in teaching,
conducted under the supervision of a "Master of
Method."
(b) Demonstration Work, with practice in making
and setting up apparatus, and exercise practical
illustration of simple Chemical and Physical
Phenomena.
The idea of the first portion is excellent, but the
utility of the second may be an open question.
Reasons have been given (Chapter VII.) for the belief
Some special problems 283
that the scientific instruction should generally be
separated from and precede technical instruction. It
would be unfair, however, to condemn the scheme
in the absence of more detailed knowledge of the
general education and scientific knowledge of the
teachers in training, and the conclusion in any case
would be determined by the critic's conception of
teaching, and of the objects at which the instruction
should aim. The experiment is of interest and
importance.
Another example has occurred in Manchester,
where the manual instructors have requested the
Department of Education in the University to arrange
for them a course of lectures on Method. 1
Turning now to the question of special training for
those who are professional teachers, we are perhaps
on more debatable ground. There are thousands
of elementary and secondary schoolmasters engaged
in evening schools. All elementary school teachers
have undergone some sort of apprenticeship, and
have received instruction in the objects and methods
of teaching the subjects that find a place in the
curriculum ; and now that evidence of having passed
through a course of instruction in the theory and
practice of education is required from those who desire
1 A question may arise as to the provision of men to conduct
these central classes. Two methods seem to be open. The
first would be to encourage good technical teachers to go
through a systematic course of instruction in the theory
and practice of teaching. The other would involve the
acquisition of workshop knowledge by men who were trained
teachers. Which was the more suitable, experience alone
could tell, and much would depend on the type of individual
selected.
2S4 TECHNICAL EDUCATION Ht EVENING- SCHOOLS
to have their names enrolled on the Register of
Teachers, there is an increasing number of secondary
teachers who possess some knowledge of the theory
and practice of their profession, so far as it concerns
the schools in which they are engaged. It is
pertinent to inquire whether this training is sufficient
to enable them to carry out in the most efficient
manner a most important part of their duties.
The training of the staffs of the Educational
Departments of the Universities is generally literary,
occasionally and in part scientific, never industrial or
technical. The specific instruction deals with the
subjects of typical day school curricula, and with the
manner of teaching them to boys between the limits
of age usually found in such schools. The subjects
of the Evening Technical School, and the aims to be
kept in view in dealing with technical students, are
disregarded.
It is a patent fact that such teachers find difficulties
in giving instruction to students whose aims and
needs are but vaguely known to them, and as the
number engaged in this work shows no likelihood of
decreasing, it seems reasonable to suggest that their
professional training should do something to fit them
for the work. The object might be accomplished in
part by attendance during the period of training of
a short course of lectures on the " Scope, Method, and
Aims of Technical Education in Evening Schools."
The instruction ought to be in the hands of a man
with industrial experience, as well as adequate
knowledge of the Theory and Practice of Education.
Such a provision, while useful to all teachers who
might ultimately teach in evening schools, would be
SOME SPECIAL PROBLEMS 285
of special value to teachers of Mathematics, Physics,
and Chemistry. These men would be the more ready
to appreciate what was required of them, and be able
to take such steps as would make their subjects at
once attractive and of direct utility to those engaged
in industrial operations.
Meanwhile, much might be done to help both
classes of teachers by the issue of special circulars
containing clear statements as to the objects to be
attained, and suggestions as to methods of teaching.
For this purpose the local authorities can command
expert assistance. In the case of a new subject —
Practical Mathematics, for example — short courses
of instruction would be of considerable advantage in
smoothing the way and avoiding much ineffective
experiment. Finally, the whole movement towards
an improvement in methods of teaching would
stimulate professional zeal and provide an impetus
which would react vigorously upon reorganisation.
1 1. — Buildings.
Arguments for a more vigorous and systematic
development of Evening Technical Education are
often met by the complaint that suitable buildings are
not available, and this forms a frequent excuse for
inactivity. Notwithstanding the number of Technical
Schools that have sprung up during the last twelve
or fifteen years, there are still many places where
classes are held in Elementary Schools which are
not adapted for the older class of students, nor
conveniently arranged for the type of instruction.
In the absence of Technical Schools, Secondary
Schools, where centrally situated, are often made use
286 TECHNICAL EDUCATION IN EVENING SCHOOLS
of; but this plan, while possessing many advantages,
is not carried out without difficulties. The head-
master of such a school is a teacher who is not
primarily interested in problems of Technical
Education. Moreover, both he and his staff are
usually fully employed. The question of general
supervision is of considerable importance, and while
the headmaster is often unable, from want of time or
other cause, to exercise direct supervision himself, the
installation of an outsider is not a very satisfactory
solution. Yet supervision is absolutely essential.
In no other circumstances can the curriculum of the
Evening School attain the unity of design and clear-
ness of aim that is a necessary precursor of its
recognition as an efficient portion of the educational
machinery of the country. Nominal superintendence
is of no use ; real, active, vigorous control is a sine
qua non.
The difficulty would probably be best met by
strengthening the science staffs of secondary schools,
and appointing a well-qualified science master who
would act as the headmaster's deputy in regard to
evening classes. Work done in this way should
count as equivalent to a certain amount of day
duty — the evening work would be an essential, to be
treated seriously, and the connection between the
evening work and the day work would react
beneficially on each. Recent criticisms 1 of the
employment of Secondary Schoolmasters in evening
schools are based mainly on the work being regarded
as an extra, undertaken in order to eke out a meagre
salary. If an equivalent amount of time is allowed
1 Report of Central Welsh Board. Also Mr. Sadler's Report
on Secondary Education in Liverpool.
SOME SPECIAL PROBLEMS 287
off duty during the day, it is not easy to see where
the harm comes in. The teacher would meet a fresh
class of students, many of them probably his old
pupils; he would deal with the larger minds and
wider views of those who were earning a living in the
great industrial and commercial world, on the out-
skirts of which he lives; and he would go back to
his day-boys with clearer knowledge, greater insight,
a more just appreciation of the aims of education,
than he could obtain in any other way.
Before leaving this question, it may be desirable to
indicate a special case which might be solved in a
particular way. Suppose there is a town of from
25,000 to 35,000 inhabitants, with a considerable
engineering or mining industry, and with a fair
amount of building going on. Let it be assumed
that from 120 to 200 students can be relied upon
to present themselves annually for instruction, and
that in the absence of a Technical or convenient
Secondary School, the classes are held in an
Elementary School. The absence of local teachers
of high qualifications, and the disadvantages of a
travelling teacher, even if one is available, stand in
the way of any extensive development, while there is
no one able or willing to undertake the post of
principal teacher. The latter post would involve a
considerable amount of time, but could be well filled
by a man appointed for the purpose, and himself
teaching on (say) four evenings a week. The
committee, however, feel that they could not under-
take to pay a well-qualified man (say) £200 to
£250 for six months' work. How is this problem
to be solved ?
288 TECHNICAL EDUCATION IN EVENING SCHOOLS
Let us suppose, now, that one of the engineering
firms would be willing to have the services of such a
man during the summer months, and to pay half his
salary, leaving him free to act as headmaster of the
Evening School during the winter. The firm would
gain by having a man with better theoretical
qualifications than the average draughtsman for
special work during a portion of the year, while the
school would gain by having a highly qualified teacher
who was in close touch with the local industry.
Lest this suggestion should appear a counsel of
perfection, it may be noted that Messrs. W. H. Allen
& Sons, Queen's Engineering Works, Bedford, regu-
larly employ a man to give instruction to their
apprentices ; and it is customary in American works
to employ a man to exercise general oversight over
the workshop progress of the apprentices. The plan
has some advantage over that in which one man is
required to give instruction in all the subjects
which may be necessary, and would be well worth
consideration.
Most Secondary Schools are now provided with
Physical Laboratories, which, with a small outlay,
would be suitable for practical work in Applied
Mechanics and Steam, where separate laboratories
are out of the question. The teaching of these
subjects, however, would be rarely in the hands of
one of the day school staff, and dual responsibility
in a laboratory is to be avoided as far as possible.
The effective oversight of the headmaster or head
teacher in the Evening School would minimise the
difficulties.
School woodwork shops require little modification
SOME SPECIAL PROBLEMS 289
to render them suitable for practical exercises in
illustration of Carpentry and Joinery, and Plumbers'
Shops are springing up all over the country. In
neither case is the cost of maintenance high. The
difference between the price of the lead at the com-
mencement of the session and the amount obtained
for it at the end of the session, for a class of twenty
students in Plumbing, need not be more than £3.
Practical work in Bricklaying and Masonry might be
carried out in a builder's yard on Saturday afternoons
during the winter, or in the evening during the
summer months. Co-operation between the em-
ployers and the school authorities in this way seems
feasible, and would be of very great value.
School metal -work shops are scarce, and it is
doubtful whether they would be of much value for
technical students. There might be sufficient
apparatus of a suitable character to demonstrate
the simpler processes of forging and hardening
tools, the use of the surface - plate and scribing-
block, and other matters that can be treated in an
educational manner. But, as a rule, the machine
tools would be of such a different character to those
found in a modern machine-shop that the scope of
the work would be strictly limited. More difficult
and complicated processes would be more effectively
dealt with in the works, and here, again, the cordial
interest which the employers are displaying suggests
that they might afford facilities for occasional
demonstrations during working hours. Such a
course would help to develop that interest in his
labour which not only makes a man a better
workman, but also makes a workman a better man.
290 TECHNICAL EDUCATION IN EVENING SCHOOLS
The combination of a Secondary Day and Evening
Technical School is only to be recommended when
separate institutions are impossible. The chief
difficulty which militates against the establishment
of small Technical Schools is the relatively small
income upon which they must relie. They are only
used for three or four hours a day against seven or
eight in the case of Secondary Schools ; the Govern-
ment grant and fees are much less in proportion to
the time they are occupied ; and but few of them are
endowed. Where small Technical Schools have been
built by a loan on the security of the local rate, the
annual sum available for Technical Instruction has
been reduced by the repayment of loan and interest.
For thirty years or so the school must bear the
burden of bricks and mortar ; teachers must be paid
inadequate salaries, and their work seriously hampered
by want of apparatus. The value of the work done
depends less upon external appearance than it does
upon the internal facilities and the spirit that
animates the instruction.
The cost of evening technical instruction is a matter
of some importance, and it is unfortunate that there
appears to be no published figures in regard to it.
The writer has before him three balance sheets from
which the approximate figures given below are taken.

SOME SPECIAL PROBLEMS 29 1
" A " is a well - equipped and well - organised
Technical School in an engineering town of nearly
50,000 inhabitants. The building is paid for. " B "
is a small Technical School in a town of under
20,000 inhabitants. The local industry does not
offer scope for development of Science and Art
instruction ; the building is fairly well equipped, and
the work well organised ; and ^120 a year is required
for repayment of loan and interest. "C" is a
" school " by courtesy only. The classes are held in
elementary school buildings, poorly equipped, and
without pretence to organisation. There is a con-
siderable amount of Engineering in the neighbour-
hood. The amount of Government grant per student
in the three cases is not a bad measure of the
efficiency. " A " and " C " are directly comparable,
while " B " labours under much more serious dis-
advantages than do the other two. On the whole,
it may be said, from a consideration of a number
of examples, that Evening Technical Schools can be
conducted efficiently on an expenditure of about £3
per head. In very small towns the cost may be higher,
because the staff is not working at its full capacity :
the same salary paid to the teacher who gives
instruction to ten students would suffice for twenty
students.
Introduction of Systematic Courses of Instruction.
The first step towards reorganisation is to secure
the co-operation of the employers. They must be
shown that the new arrangement is to their advantage.
In this connection it is a matter for regret that con-
ferences often come to no conclusion owing to the
292 TECHNICAL EDUCATION IN EVENING SCHOOLS
absence of definite proposals and lack of knowledge
of what is being done elsewhere. The ground might
be prepared by first issuing a circular containing
information similar to that in Chapter V. ; and the
MS. of this portion of the book has been used in one
case with excellent results. The employers might
be asked to indicate their preference for one or
other of the schemes : a subsequent conference
between them and the Education Authority would
probably lead to agreement upon some definite
scheme of co-operation.
The institution of a standard of admission would
necessitate a distribution of students between the
Continuation and Evening Technical Schools ; but
this could be effected gradually, and need not
concern those who have already attended the classes
for one or more years under the old regime. There
is no reason to believe that insistence on courses of
instruction would lead to any reduction in the
number of students ; indeed, in the example
mentioned above, in which the influence of the
employers was obtained, the number rose. If the
students are told that the change is for their benefit,
if the courses are advertised as a whole, meeting at
certain hours on certain days of the week, unpopular
subjects being hidden under the general title of the
trade, and a composition fee charged for the course,
there would not be much difficulty in getting them
to attend. Regularity would be encouraged by
confining privileges in the works and the school to
those who took the course and made the highest
average all-round attendance.
A matter of considerable importance is the number
SOME SPECIAL PROBLEMS 293
of students necessary for systematic courses. Twenty
students from one industry will often be the lowest
where a single school is under consideration. With
a hundred students in three industries, a three years'
course could be carried on without difficulty. The
larger classes in subjects common to the first year —
such as Mathematics and Geometry — would com-
pensate for the smaller classes in certain third year
subjects. Moreover, in Drawing, second and third
year students can often be taught concurrently
when the numbers are not large. Again, if the
annual influx of new students was small, or
the teaching staff limited, a first year course
could be commenced in alternate years ; a case
of this sort has actually occurred. In fact, there
seems to be no reason for the existence at any
time of the single class in Machine Drawing, Building
Construction, or Mining, when the problem of the
supply of teachers has been satisfactorily solved.
If it is possible to teach one subject to ten students
on fees and grant from various sources, it must be
possible to teach four subjects to the same number ;
subscriptions to evening technical classes are rare,
and, when given, are usually devoted to prizes.
It must be borne in mind that many districts
consist of a number of small towns connected by
frequent trains or trams, and what might be impos-
sible when each school was considered alone becomes
easy when the district is organised as a whole. In
such cases there would be a considerable number of
schools providing instruction in the first or first and
second year's courses. Students who had passed
successfully through these would be concentrated
294 TECHNICAL EDUCATION IN EVENING SCHOOLS
in a smaller number of schools, in which they could
continue their systematic studies. The scheme for
Technical Exhibitions of the Yorkshire (W. ! R.)
County Council (p. 154-9) provides for an arrange-
ment of this sort within the area under their control,
and the South Wales Coalfield is another district
which presents many opportunities for a similar
organisation.
The effect of all special education is more or less
narrowing in character. When this has to be
acquired during leisure hours, it is particularly
important that the organisation and methods of
instruction should lead as directly as possible to
the goal. Still, it is quite possible to liberalise the
training without decreasing its special value. To
this end there should be a connection between the
Free Library and the Evening School, and it ought
to be the duty of the teachers to indicate the sources
to which an earnest student may look for freer
treatment and fuller information.
The smaller centres, in places where there is no
Free Library, should be supplied with a small
collection of books. Those bearing on the work
of the classes should be of two kinds : there might
be a few standard text-books for the use of the
teachers and advanced students, and there might
also be a few books in which the dry bones of fact,
formula, and theory are clothed with literary grace,
and vivified with the imaginative spirit. Thus
engineering classes should not only be provided
with a few standard works on Machine Design,
Applied Mechanics and Steam, but also with some
of the excellent popular works on engineering
SOME SPECIAL PROBLEMS 295
triumphs, and the biographies of famous engineers.
An outlay of £10 would provide from fifteen to
twenty volumes, and these ought to be considered
as essential as apparatus.
This special library should be supplemented by
weekly and monthly papers and magazines. The
cost could be met out of the composition fee, and
it would not be difficult to dispose of the magazines
at half-price. A room should be set apart for the
use of such students as have few facilities for study or
home work in their homes or lodgings. The school
would thus gradually acquire the character of an
institute, and exercise thereby a greater hold over
the students.
There is a considerable field for University exten-
sion and other lectures in connection with Evening
Schools, and it is unfortunate that they are frequently
under different management. Among the results of
this independence have been unsuitable choice of
subjects, and considerable interference with the work
of the schools. The educational value of University
Extension work might be much increased by its
closer association with the Evening School, and the
time-table of the latter should be framed so as to
allow of the students enjoying the benefits of the
lectures with the least possible disturbance of the
systematic instruction. However, to pursue the
various methods of rendering Evening Schools
more efficient in relation to those activities not
directly concerned in obtaining a livelihood would
be to step outside the province of this book,
the main object of which has been to discuss
the merits, defects, and improvement of such
296 TECHNICAL EDUCATION IN EVENING SCHOOLS
schools from the point of view of Systematic
Technical Education.
Of the ultimate success of well-devised schemes of
instruction, or of their value to industry, the writer
has little doubt. A long familiarity with evening
students, particularly with those engaged in the
trades considered, has convinced him that there is
no more hard-working set of men in the community.
Ill-assorted, and often ill -prepared they may be,
groping in the dark, and feeling their way by such
landmarks as are dimly visible ; but still earnest,
painstaking, willing to take advice, ready to " scorn
delights and live laborious days," prepared at any
sacrifice to grasp the opportunities held out to them,
and to play their part in the industrial conflict which
threatens every year to rage more furiously among
the nations. The possibilities of Technical Education
were never more clearly seen than when John Tyndall,
speaking in London in 1879, pointed to "the intel-
lectual Samsons toiling in the mills and at the forges
of Lancashire and Yorkshire," and said : " Give
those men the teachings of Science, and you will
multiply the chances of discovery, diminish the
causes of calamity, and materially enhance the
prospects of national advancement."

A. THE COST OF COMPULSORY CONTINUATION
SCHOOLS.
B. NOTE ON MINING INSTRUCTION.
C. THE PROVISION OF APPARATUS.
A. The Cost, etc., of Compulsory Continuation Schools.
In view of the public interest which at the present time is
exhibited in a system of Compulsory Continuation Schools, it
may be useful to make a rough calculation of the cost of the
plan outlined in Chapter II. Taking the figures 1 for 1902-3,
we find that the number of scholars in Elementary Schools
between certain limits of age was as follows : —
Between 12 and 13, - - 557,868
,, 13 » 14, - - - 351,288
>. 14 „ 15. " " 53,°i°
In round numbers, therefore, 206,000 children leave school
at 13 years of age and 300,000 at 14. According to the
scheme, the former would be required to attend the Continuation
School for 4 years, and the latter for 2 years. Assuming that
the scheme were put into operation generally, the following
numbers would have to be provided for during the first four
years : —
1 st Year, 500,000
2nd „ - ... 1,000,000
3rd „ - 1,200,000
4th „ ... 1,400,000

Table 2.

298 APPENDIX
The last number represents the number of children for which
accommodation would ultimately be required, subject to any
change due to raising the standard of exemption from attend-
ance at the day school, and an increase in the population. It
is interesting to note that the number of students under 15
years of age who attended an evening school during the session
1902-3 was 147,191. Ignoring the fact that not more than 40
per cent, or 50 per cent, were in regular attendance throughout
the year, it is evident that not more than about one-tenth of
the available material comes under the influence of the evening
school, and taking the average attendance into account, only
5 per cent, of the children who leave school under 15 continue
their education.
The next question is the cost of providing education for
these children. The average cost of maintenance in
Elementary Day Schools throughout the country is about
£2 14s. per child. 1 The elementary day school meets for
27$ hours a week, the evening school may be assumed to
meet for 6 hours a week. Assuming the cost for heating,
cleaning, and teaching to be proportionate (that for lighting
would be a little more), the cost in evening schools would be
roughly two-ninths of the cost in day schools for the same
length of time. As, however, the evening school session is
six months as compared with nine months in the case of the
day school, the cost would be $xf = jV of the cost in the day
school. This gives 8s. per head. In order to allow a margin,
and make the argument safer, the cost may be put at 10s.
Now, in any system of Compulsory Continuation Schools,
certain exceptions have to be made. Moreover, as the
difficulties of securing regular attendance will be greater, it
will not be advisable to calculate on a greater average than 70
per cent. The total cost to the nation, then, would be that of
1,000,000 children in average attendance at 10s. per head, or
^500,000.
In making an approximate estimate of the effect on the rates,
it will be simpler to omit any amount due to capital charges,
'The amount for 1902-3 is not available owing to changes brought
about by the Act of 1902. The amount for 1901-2 was £2 13s. 2d.
AffENDlX 299
which are necessary in any case. The figures below refer to
1901-2. 1
Cost of Elementary Education under School Boards in England
and Wales, omitting Capital Charges and Repayment of Loans.
Maintenance, - ... £8,194,789
Administration, . 530,380
Miscellaneous, - - - 250,773
Total, - £8,975,942
Of this amount, which may be taken as £9,000,000, 60 per
cent, comes from the rates and the rest from fees, grants, etc.
Assuming the same proportion to hold in evening schools, the
amount required from the rates would be £300,000, and from
the Board of Education, £200,000. Taking the average rate
throughout the country to be is., of which 16 per cent, is
expended in Capital and Loan Charges, the remaining 84 per
cent., or a iod. rate, produces £5,400,000. The £300,000
required from the rates therefore represents an increase of a
little more than a |d. in the £ over the School Board areas
as they existed in 1901-2.
The foregoing estimate has been based on the figures for
Elementary Education rather than on figures for the cost of
evening schools, because the work of such schools as are under
consideration would be essentially elementary, carried on in
elementary school buildings, by elementary school teachers.
The lack of efficiency and economy under the voluntary
evening school system renders the present cost unsuitable as
a basis for estimation. Two points, however, call for attention.
The staffs of elementary schools are in part pupil teachers who
could not be employed for evening work, and it would be
extremely undesirable to clog the machinery of evening schools
with the large classes that obtain in elementary schools. Since
the chief item of expenditure would be salaries, a universal
efficient compulsory system of evening schools would cost
nearly £1,000,000 per annum. This would correspond roughly
to a id. rate levied by the local authorities and an increase of
1 Report of the Board of Education for 1002-3, p. 41.
300 APPENDIX
about 4 per cent, in the Exchequer grant, assuming that the
proportions given on a previous page hold for these schools.
It must be emphasised, however, that no one contemplates an
immediate and universal establishment of compulsory evening
schools, and a comparatively small outlay would permit of
much useful experiment, and help to form public opinion on
the subject.
Opponents of compulsory evening schools frequently put
forward the difficulty of enforcing the law as an argument
against the institution. Under the scheme suggested, per-
mission to leave school below fifteen would be granted as a
privilege, and on conditions which must be fulfilled. If
attendance at the evening school subsequently is unsatisfactory,
the child forfeits the privilege and becomes ipso facto a truant,
to be dealt with in the usual way. Instead of destroying
parental responsibility, which as a matter of fact is frequently
bartered for the few shillings a week which the child can
earn, the scheme would stimulate this virtue. To retain the
privilege, the parent must exercise control over the child.
Again, those who would oppose compulsion on the ground
that the child is too tired after the day's work to undertake
mental exercise must, if they are to be consistent, object quite
as strongly to gymnastics, football, cricket, and other pastimes.
For it may be asserted most emphatically that the change from
the workshop to the school is no more tiring than a prolongation
of bodily exertion. Finally, the moral effect of an extension of
school discipline at this period of life, and during the winter
months, outweighs in value nearly all other arguments from the
point of view of national welfare as opposed to individual interests.
B. Note on Mining Instruction.
In support of the view that the Mining student should
undergo instruction in a group of subjects, it will be useful to
give a typical Home Office Examination Paper for the Colliery
Manager's Certificate. The Paper selected was set by the
Stafford District Board in April, 1903, for First Class Certifi-
cates. 1 It may be left to any competent critic to say whether

C. The Provision of Apparatus.
It has been remarked (p. 288) that a comparatively small
outlay on Apparatus would render a Physical Laboratory suit-
able for instruction in Applied Mechanics and Steam in those
places where separate laboratories are out of the question. As
there are probably about 300 Physical Laboratories as against
30 Laboratories for Applied Mechanics, and still fewer for
Steam, available for evening students, an estimate of the cost
may be useful.
Dealing first with Applied Mechanics, it may be assumed
that the Physical Laboratory is already equipped with micro-
meter gauges, pulleys, spring balances, weights, levers, and
inclined planes. In the list given below, the apparatus under
Part I. is essential, that under Part II. desirable.

It should be observed that the comparatively small demand
for apparatus of this sort considerably enhances the price,
which is distinctly high. A good deal might be saved by
having some of it constructed in the school workshop.
In regard to Steam, much will depend on the preliminary
training of the students. If they have previously done no
practical work in Heat, the resources of an ordinary Physical
Laboratory will be ample for their requirements, but a Marcet's
Boiler, costing about £3, should be obtained. Students at this
stage should aim at securing clear notions of the properties
of vapours, specific and latent heat, conduction and connection,
and the mechanical equivalent. Beyond that they may be
profitably employed in plotting curves of crank effort, and the
motion of valves with various gears, with simple models. The
cost of the latter is rather heavy : they are from £2 to ^10
each ; but the writer has seen many home-made models which
serve the purpose equally well. A good deal of work might
be done on the mechanism of the Steam Engine on an expen-
diture of ^20 to £25. There can be no upper limit for either
this subject or Applied Mechanics, and money spent in im-
proving the equipment for these classes would be returned in
the greater efficiency of the instruction.
In regard to the better provision of apparatus for all subjects
at smaller centres, a wide field of experiment is opened out.
Local authorities who have a number of classes under their
control would find it an advantage to establish a store-room
in which the more expensive apparatus would be kept, and

distributed to the classes according to a definite system. The
logical order of treatment is of less importance in the case of
applied than pure science, and if teachers knew at the com-
mencement of the session between what dates certain pieces
of apparatus would be in their possession, they could arrange
their work accordingly. The stores might have a workshop
attached in which the old apparatus might be repaired, and
new apparatus constructed according to the designs of teachers.
This would enable the equipment to be kept up to date, and
provide a stimulus to the teachers which could not fail to react
on the value of their instruction. If one of the local authorities
would institute such a store-room and workshop- for (say) a
period of three years, they would be carrying out an experiment
of no little importance.
A store-room of the kind described might perform another
function. It is well known that many manufacturers are willing
to supply samples of their work for a longer or shorter period
to the larger technical schools, and this is probably an excellent
form of advertisement. Smaller schools, with (say) 20 or 30
students per annum, cannot lay claim to the same consideration,
though cases are known in which applications from quite small
centres have met with a ready response. The store-room with
an adequate system of distribution would offer exceptional
advantages, and judging from an example which the writer has
in mind, the offers might be so liberal as to call for the exercise
of no little judgment in deciding what could be accepted. But,
carried out intelligently, the plan would have the best effect on
teachers and students, and would contribute in no small measure
to the closer union of Technical Education and Industry.
