KELSEY WARM AIR GENERATORS* briefly described 
 
 H 36asc Cast in one piece, forming the bottom of Ash¬ 
 pit and a substantial support for the outside 
 galvanized iron Casing. 
 
 Bn Bsb=pit Fitted to the base with a cup joint, absolutely 
 preventing escape of dust into the warm air 
 chamber. Sides of Ash-pit are straight, allow¬ 
 ing use of an ash-pan when desirable. 
 
 XIbe Grates Provided with all our Generators are the Smyth 
 Pattern, having four revolving bars, triangular 
 in shape, presenting to the fire a new surface at 
 each one-third revolution. The bars being each independent, any one 
 can be replaced without the expense of an entire new grate. 
 
 ^ Is the essential feature of our Generator, which 
 
 jfirc=Cpltnber entirely removes it from the plane of Hot Air 
 Furnaces. By placing at the top of the Ash- 
 tTnm hti ph, immediately around the grate surface, a 
 
 VIC nil Italic It number of hollow cast iron sections, nearly 
 Chamber V ” shaped, a perfect cylinder is formed. 
 
 Notice that the form of these “ V ” shaped, 
 hollow sections, as they face the fire, is perfectly straight; thus prevent¬ 
 ing any accumulation of ashes about the sides of the Fire-clyinder. 
 That part of the lower end of each of these upright, hollow sections, 
 against which rests the fuel in combustion, is 4 inches wide, and 12 
 inches long, and the thickness of this part of the section is l l 8 inches. 
 It will be noticed that the sides of these sections are deeply corrugated, 
 and in form, widen at the top, thus exposing the greatest amount of 
 heating surface possible directly over the fire. The backs of these 
 hollow, corrugated sections, project one inch beyond the corrugated 
 sides, so that as they stand in position the backs of the sections overlap 
 each other, except for six inches at the top, where the space between the 
 corrugated sides of the sections is left open to provide escape from the 
 combustion chamber. 
 
 Enwraps the castings of our Generator above 
 the Ash-pit, there being a 3-inch space between 
 the backs of the hollow, corrugated sections 
 and this inside Casing, providing a Draft Cham¬ 
 ber for the Generator. 
 
 Of our Generator is made of heavy galvanized 
 iron, lined with Asbestos Sheathing and Tin. 
 You will observe that our Outside Casing is 
 not placed directly adjacent to a large, seething, 
 red-hot fire-pot, the result being that the Outside Casing of our Generator 
 never becomes so much heated as to warm the cellar to any perceptible 
 degree, a separate partition in the cellar being unnecessary to separate the 
 Generator from the choicest fruits and vegetables. Damper Regulators 
 are provided with each of our Generators, for perfectly controlling the 
 drafts from the first floor. 
 
 Which form the Fire-cylinder and Combustion 
 Chamber of our Generator, and through which 
 passes the fresh air conducted to them, have 
 each an inside measurement at the lower end 
 of 36 square inches; inside measurement at the 
 Corrugates upper end, where the heated air is discharged, 
 _ 46 square inches; length of all sections (ex- 
 
 ^ “ cept in No. 14 Generator), 36 inches; thickness 
 
 of all sections where they face the fire 1 }i inches; weight of each of 
 the sections about 70 pounds. Each of these long, hollow sec¬ 
 tions has 8 square feet of heating surface, making it really a small, 
 independent Generator of itself; and notice, the fresh air as heated in 
 these hollow sections forming the Fire-cylinder and Combustion Cham¬ 
 ber, instead of being radiated outward, is retained in and conducted 
 upward through these sections to the very top of the Generator, rising 
 with great velocity in separate currents, immediately taking the heat 
 conducting pipes to the several rooms to be heated. We guarantee heat¬ 
 ing distant rooms with absolute surety with our Generator, by capping 
 such a number of these long, hollow sections, as the occasion may require.

 The extreme capacities given above are based upon conditions where but one or two heat conducting pipes are required; when using 
 an increased number of such pipes, there is a consequent loss of heat from radiation, for which due allowance must be made in selecting

 INSIDE STEEL CASE LINE 
 
 KELSEY GENERATORS 
 
 ARE CLOSELY ALLIED TO A STEAM 
 OR HOT WATER HEATING PLANT. 
 
 T HIS cut shows the bare castings of the Generator all in 
 proper position, excepting three of the long, corruga¬ 
 ted sections, which are removed to allow better view 
 the interior of the Heater ; the cut also represents one of the 
 long sections standing alone thus to better show its entire 
 outlines. 
 
 NOTICE PARTICULARLY: 
 
 The surpassing area of cast iron surface, placed directly 
 adjacent to heat produced by fire in combustion. 
 
 How the long, hollow, corrugated sections are heated their 
 entire length, by the upward course of all products of combus¬ 
 tion in their escape from between such sections at their back 
 and extreme upper end. 
 
 How that the fresh air conducted to the Heater, in its 
 upward course through the long hollow sections, is brought in 
 the most direct contact possible with the heated surfaces of all 
 the castings. 
 
 How that with the fire cylinder built up of these long, 
 hollow corrugated sections, each a little space apart, ample 
 provision is made for the expansion and contraction of this 
 portion of the Heater, doing away with the replacing of cracked 
 fire-pots. 
 
KELSEY GENERATORS 
 
 ARE SO CONSTRUCTED THAT THEY DO 
 NOT HEAT THE CELLAR IN WHICH THEY 
 ARE LOCATED. 
 
 T HIS cut shows the Generator with all the castings perfectly 
 erected, and the heavy inside Casing in position, with a portion 
 of same broken away, to bring clearly in view the long down draft of 
 the Heater. 
 
 NOTICE PARTICULARLY: 
 
 Every casting in the Heater above the Ash Pit is encased in the 
 heavy inside casing, thus retaining a uniform and maximum heat in 
 the sections, through which is passing the fresh air conducted to the 
 Heater, and with the heated castings thus heavily encased, effective 
 means are provided to assure as cool a surface as possible for the out¬ 
 side galvanized iron casing. 
 
 Observe that the backs of the long, hollow corrugated sections are 
 thoroughly heated, by the products of combustion passing over same 
 in their escape from the combustion chamber to the smoke-pipe lead¬ 
 ing from the Heater. 
 
 The long down draft of the Heater is such as to secure the benefit 
 of all particles of heat generated by the fuel in combustion.

 SURFACE ECONOMIZE FUEL. 
 
 T HIS cut shows the Generator cased complete, with 
 portions of the same so broken away as to accu¬ 
 rately represent the Heater in operation ; also repre¬ 
 sents a single one of the long, hollow corrugated sec¬ 
 tions, showing clearly its exact form and thickness at 
 the lower end, where it is directly adjacent to the fire. 
 
 NOTICE PARTICULARLY: 
 
 The great amount of heated surface, over which 
 passes the fresh air conducted to the Heater. 
 
 The direct and unimpeded passage of the fresh 
 air through the Generator to the pipes leading to the 
 separate rooms to be heated. 
 
 The unique design for equally distributing the 
 heat over all the castings in the Generator, thus assur¬ 
 ing an even flow of heated air through all the pipes 
 leading from the Heater. 
 
 How distantly removed is the fire in the Generator 
 from the outside galvanized iron casing, thus provid¬ 
 ing against making the cellar one of the warmest 
 rooms about the house. 
 
 The large, low-down feed door. 
 
KELSEY GENERATORS 
 
 HAVE A MOST COMPLETE AND EF¬ 
 FECTIVE HOT WATER ATTACHMENT. 
 
 T HIS cut shows the Kelsey Generator set up 
 complete, with portions of the castings and 
 casings broken away to show clearly the loca¬ 
 tion of the Hot Water Attachment and connections 
 therewith. The efficiency of this attachment is such 
 that it provides an ample supply of hot water for bath 
 rooms, wash bowls, laundry purposes, baptistries, etc. 
 
 NOTICE PARTICULARLY: 
 
 The location of this Attachment is such (forming 
 that portion of the fire cylinder directly under the 
 feed-door) that it detracts the very least possible from 
 the radiating surface of the Heater, and withall is so 
 positioned that with any fire in operation the Water 
 Back must be heated, and so rendered efficient for the 
 work required. 
 
 The Water Back is so placed that it can be easily 
 removed, and a new one placed in position, without 
 disturbing any other portions of the Heater. 
 
 The cost of this valuable Attachment is nominal, 
 as compared with anything on the market of like 
 nature and efficiency.

 T HIS cut represents only the style of construction and perfect 
 working of our Positive Cap Attachment, as located over two or 
 more of the long, hollow corrugated sections forming the Fire 
 Cylinder and Combustion Chamber, and through which passes 
 the fresh air conducted to the Generator. 
 
 NOTICE PARTICULARLY: 
 
 How each of the long, hollow sections, from the position they occupy, 
 are really a small and independent Heater in and of themselves, receiv¬ 
 ing as they do each their own proportionate amount of fresh air and 
 contributing the same, thoroughly heated, to the general heat supply of 
 the Generator. 
 
 How by capping any number of such hollow sections, and extending 
 a pipe from such Cap Attachment to any room desirable to have heated, 
 all the fresh air passed through the sections capped must be delivered in 
 the rooms thus connected with the Generator. 
 
 How by closing damper Z, as shown where placed over sections JJ, 
 the flow of heated air through such sections is turned wholly into the 
 general heat reservoir, to be used in supplying other pipes leading from 
 the Generator. 
 
 We furnish, without any extra charge, our agents with these Posi¬

 KELSEY FURNACE CO., Syracuse, N. Y., 
 
 Gentlemen :—Nearly everyone who builds a house, says that deciding upon the question of heat is the greatest difficulty they encoun¬ 
 ter. We were no exception to the rule—Were we now to build another house, no matter what the conditions, if it required heat, the 
 Kelsey Generator would supply it, and we would not even consider the matter, except to get your best price. If you want a more de¬ 
 tailed statement, you are welcome to it. 
 
 My house is 49 feet front, 34 feet deep, three stories high. The entire first floor opens with sliding doors, into practically one room. 
 The past winter, we heated the entire house, seventeen rooms, two halls, 14x34 feet, and two smaller halls, with one No. 30 Generator. 
 The amount ot coal burned seemed very small, compared with the results obtained. Not once during the winter, did the house have the 
 oppressive “heavy" feeling caused by the intensely hot air usually poured into a house, from the ordinary Hot-air Furnace. When 
 coming in from out-doors, it seemed like stepping from winter to summer—the air was always fresh and delightful. The verdict of my 
 entire family is, that it was the most perfectly heated house that they had ever seen. 
 
 I do not know what I can add to the above, except that it is a pleasure to send you this sincere testimonial. 
 
 Yours truly, 
 
 Gaston T. Hubbard.

 REUBEN REYNOLDS, Esq., Kingston, N. Y., 
 
 Dear Sir :—Replying to your inquiry concerning satisfaction given by the No. 21 Kelsey Generator which you placed in my home 
 last fall, it gives me great pleasure to state that the Heater has, in all respects, more than met my expectation. I have found it more 
 economical than stove or Steam heat, accompanied with an entire freedom from dirt and dust, and requiring very little care or attention. 
 The offices of our firm are heated by steam, and I have had experience with the different methods of heating. I find that the atmosphere 
 of my home, heated by warm air, is much more pleasant and agreeable than that of my office, heated with steam. Going from the dry 
 and oppressive air of the office, to the fresh, live and wholesome air of my home, presents to me the very marked difference in the condi¬ 
 tion of air heated by steam, and that heated by the Kelsey Generator. 
 
 At no time during the past winter, have I found any difficulty in maintaining an even temperature throughout my house, and by use 
 of the cold air shaft, have been able to ventilate the house better than ever before. I am in every way pleased with the Gt neiator. 
 
 Respectfully yours, V. B. VanWagonen.

 MR. J. C. CONNER, Evanston, III. 
 
 Dear Sir :—In replv to your request for my opinion of the 
 merits of the Kelsey Generator, I would state that I have 
 used two of them. I placed one in a house for a tenant at 
 Evanston, and his very favorable report led me to buy one 
 for my own home. I had a large furnace in my own home at 
 Lake Forest, which could not be made to give fair results, 
 with any amount of care or coal, so I replaced it with a 
 No. 30 Kelsey Generator. The ratio of coal to heat was much 
 less in the “ Kelsey” than in the other heater. With it you 
 can heat a house very quickly. Its economy of coal is 
 particularly noticeable in moderate weather, when a small 
 but steady fire is desired. It has proven very satisfactory. 
 The extreme measurements of my house are 50x80, with 
 about 54,000 cubic feet capacity. 
 
 Yours truly,

 Dear Sir :—It gives me great pleasure to recommend your “Kelsey Generator”. The one placed in my house last fall, has given 
 complete satisfaction. During the coldest days of the past winter, I have averaged one and a half tons of coal per month, and during the 
 average cold days, I have used about one ton per month, My house is exposed on all sides, and gets the full effect of the N. W. winds. 
 The house has been warm and comfortable at all hours, and the air pure and fresh. What more can I say ? The “Waterless Boiler” is 
 a grand success. Very truly yours,

 Dear Sir :—I am in receipt of yours of the 9th inst., and in reply would say, that the members of the “Indiana Club” are all pleased 
 with the “Kelsey” Generators which I have put in for them. They are working to perfection, and the quality of the air to breathe is 
 often spoken of. We have but one fault, and that is, the Janitor allows the rooms to get a little too hot at times. The Hot Water Attach¬ 
 ment on the No. 30 has 67 feet of radiation attached to it, and does this work with ease, and I think it would be safe to use it up to 100 feet.

 Gentlemen :—I have had three Furnaces in my home, during the past five years, and not one of them have given me satisfaction. I 
 now have your Generator in use, and it gives us entire satisfaction, and that with a saving of from three to six tons of coal, from what 
 we previously used, in the Furnaces which we had. Our house is large, containing twelve rooms, with large Halls, and rooms on each 
 side of same, on three stories. We are delighted with the “Kelsey.” Very truly yours,

 KELSEY FURNACE CO., 
 
 Gentlemen :—In reply to your inquiry, I am glad to give my testimony in favor of the “ Kelsey Generator.” The No. 24 placed in my 
 residence four years ago, has given complete satisfaction. The Positive attachment of your Heater is in my opinion, a very valuable 
 feature. In my home, by means of it, a bath room in the northwest corner of my house, having a horizontal pipe about thirty feet long 
 leading from the heater, is made one of the warmest rooms in the house, while before, with the furnace which I removed at the time of 
 placing yours, no heat whatever could be obtained through the bath-room register, and the room was comfortless and nearly useless in 
 the winter. That this improvement in the heating of my bath-room is due to the Positive Attachment is clearly shown by the fact, that 
 now, unless the damper in the Positive Attachment is closed, so as to divert all the heat from the sections capped into the pipe leading 
 to this bath-room, no hot air reaches said room when the wind is northerly or westerly. My house is exposed on all sides, has thirteen 
 rooms in communication with the heater, and the windows are large and numerous. The Generator is very easy to manage, and is free 
 from gas and dust. Yours truly, C. B. Richards,

 I am very glad to be able to assure you of my entire satisfaction with the manner in which you have heated my house at Devon. 
 Although situated in an unusually exposed position, I am now able to keep the temperature at about seventy degrees in halls, living 
 rooms and chambers, both night and day, during the severest weather. Your system presents decided advantages over direct steam heat, 
 in that the house does not become overheated in moderate weather, and is always supplied with abundance of fresh air.

 Gentlemen:—The No. 21 Kelsey Generator you placed in my dwelling of eleven rooms, No. 50 Hanover street, gives great satisfac¬ 
 tion. I estimate that the saving in fuel of this furnace over the one it has displaced has been about $35.00 in one season. The Kelsey 
 operates with much less attention, and heats the rooms that were poorly heated by the former furnace driven to fullest capacity. We 
 also experience a pleasant relief from dust and gas. While my Generator has the same size grate as the former furnace, we get 50 per 
 cent, better results from the coal burned. Yours truly.

 MESSRS. H. C. GEISSLER & SONS, 
 
 Gentlemen: —Y T our favor of the 26th inst. received, requesting me to give you my experience with the Kelsey Warm-Air Generator, 
 
 which I will cheerfully do. You will remember that I had placed in my house one of the largest sizes of the best make of regular 
 
 heaters, which I had used two years, and by us ; ng from ten to thirteen tons of coal I was unable to heat certain parts of my house satis¬ 
 factorily. Others thought that my house could not be heated unless I used two heaters, which I disliked to do. I made arrangements 
 for a Hot-Water Heater when the “Kelsey” was recommended by you. Your liberal guarantee, placing no responsibility whatever upon 
 me if it did not prove entirely satisfactory after a winter's trial, induced me to allow the Kelsey Warm Air Generator to be placed 
 in my home to demonstrate your guarantee and show the difference in the two kinds of heaters. My experience during this last winter 
 
 of 1896-97 is such that I am more than delighted with the result. My house is a large one, ten rooms and large hall, all iiJ 4 f eet ceilings, 
 
 exposed to all the winds from all directions, but will say here that each and every part of my house from front to rear has been equally 
 well heated and did not use quite eight tons of coal. The heater is mostly used with the drafts turned down and the entire freedom from 
 gas and dust is worthy of mention. I desire to say that I would not exchange the Kelsey Warm-Air Generator for any steam or hot 
 water system in the market. Yours truly, 
 
 A. A. Illig.

 Gentlemen :—The No. 18 Kelsey Generator which you placed in 
 my residence two years ago, has given me excellent satisfaction, 
 having heated my house of eight rooms and hall, with no trouble, 
 during the coldest weather. The strong point in favor of the 
 Heater is the saving of fuel. I run my Heater with four tons of 
 coal for five months each winter, and held the temperature at 
 seventy degrees night and day. 
 
 I also built a house for another party, exactly like my own 
 residence, and they placed in the same a furnace of another make, 
 the best one they knew of, except the “ Kelsey,” and they used 
 eleven tons of coal in the same length of time that I used four tons. 
 
 I would advise any one who desires a Heater, to purchase a 
 “ Kelsey,” and have you place it for them, as I am satisfied the 
 work will be done satisfactorily. 
 
 Yours truly,

 failed to properly heat the block. Second : when recently one extra room to be heated was added to each flat, the statement was then 
 
 made to me, by other heater men, that the only way to heat it with hot air, was to employ two furnaces. Third : your Generator has 
 heated the flat as never before, giving the proper amount of pure, warm air, to every room. Its working is simply perfect.

 is the third furnace I have used, and we do not get that dry, stuffy heat as from the others, but a mild, summer air at all limes. To 
 
 those wanting a high grade Heating apparatus, I would by all means advise them to get the “ Kelsey,” have it properly installed, and 
 
 it will give entire satisfaction. Henry Hayden,

 before selecting a heating apparatus to warm my house at Merion, Pa., the subject was looked into very thoroughly, in order that the 
 proper principles might be secured. In the “Kelsey Generator” it is my opinion that the maximum heating surface has been obtained 
 proportionate with the size of the apparatus, and that the proper principles have been applied in its construction, as a result of which, 
 combined with my experience of two winters, I am enabled to testify to its merits as a thoroughly reliable heater, with no bad points 
 and everything in its favor, particularly the ease with which it can be managed, and its economy of fuel. 
 
 Very truly yours, Henry Delaplaine.

 same two winters. I find it well constructed, simple in management, and economical in consumption of fuel. I have used four different 
 styles of Hot Air Furnaces, but the “ Kelsey ” has proven the most economical of fuel, and satisfactory Heater of the lot. I use a No.

 cubic feet of space, divided into 22 rooms, and could have been 
 heated to 80 degrees, without any trouble, when mercury was 
 below zero. 
 
 In addition to heating the building, the Generators heated a 325 
 gallon boiler, which furnished an abundance of hot water for bath 
 and toilet purposes.

 season since, as the means of heating my home. Our entire house is thoroughly and evenly heated, with the use of an average amount 
 of five tons of coal per year. 
 
 Since the Generator was placed, I have never had occasion to have any repairs, whatsoever, made on the same, have never had any 
 trouble from the use of the Heater, never a particle of escaping gas from same, and in so far as I can judge, the Heater is as good to-day 
 as when first placed. I gladly recommend the Kelsey Generator to any one wanting a first-class Heater, and one that does not require 
 constant repairs. Very truly yours, George B. Clark, East Onondaga.

 the gallery having a surface of 37S square feet of glass exposed to outside air. 
 
 The large volume of heated air from the Generator is pure, and equal to the temperature of a Steam or Hot Water Plant. It has 
 proven very economical, when compared with other heaters of which I have knowledge.

 Dear Sir :—The Kelsey Generator which I bought of you last summer, and with which my house has been warmed during the past 
 winter, has given entire satisfaction. My house contains nine rooms, besides bath room and hall, and we were able to keep it at a 
 regular temperature of about 72 degrees Fah. with very little trouble, and with the consumption of a comparatively small amount of fuel. 
 Seven tons of Poccahontas coal only were used, beginning in September last year, and continuing until the first of May this year. We 
 have had no other heat in the house since it was built. 
 
 For simplicity of construction, ease of management, and economy of fuel, I do not see how the Kelsey Generator could be improved 
 upon. It certainly will satisfy any reasonable person.

 Dear Sir When I started building my present residence, I was advised that it would be impossible to heat it, except with steam 
 or hot water. A friend advised me to try one of your Kelsey Generators, which I am happy to say, has given perfect satisfaction. 
 
 I notice particularly, the absence of radiation from the smoke pipe and outside covering of your apparatus. This conclusively shows 
 that the heat does not go up the chimney, or remain in the cellar, but is distributed about the house. 
 
 I can unhesitatingly recommend your Generator to any one who is contemplating building.

 Dear Sirs :—The Kelsey Generator placed in my residence is entirely 
 satisfactory. I am heating in my residence, eighteen rooms, without any 
 difficulty during the coldest weather, all of these rooms being in constant 
 use, and it has never been found necessary to close off any part of the house. 
 Among these rooms, is a Nursery on the second floor, 16 x 25 feet. This 
 room has ten windows opening south, east and west, and is always 
 thoroughly comfortable, it being often found necessary to turn off part of the 
 heat. On the third floor, there is a suite of five rooms, parlor, library, two 
 sleeping-rooms and a bath-room, all large sized rooms, the largest being 
 16 x 19 feet. These rooms are always heated. The air furnished is excel¬ 
 lent, and the Heater is easily controlled, and does not burn an excessive 
 amount of coal during the season. I have also a No. 18 Generator in my 
 stable doing its work easily, it never having been run at more than one-half 
 its capacity, heating the main floor, harness-room, office, and two upper rooms, 
 a sleeping-room, and work-room, supplying Hot Water to the bowls and 
 catriage-washes. This Heater having a water-front connected with a Boiler, 
 the same as ordinarily used with a range, furnishes an unlimited amount of 
 hot water, and is a most effective and satisfactory arrangement. I take 
 pleasure in furnishing you this testimonial.

 the coldest weather, and this without any crowding whatever. One ton of coal per month is all 1 have been obliged to use, to produce 
 this result. I have found it necessary to keep all dampers closed, and all cold air checks open, in order to prevent the house from 
 becoming overheated. I shall be glad to recommend the “Kelsey” to any one contemplating the installation of a Heating Plant.

 the additional cost of fuel. You assured me this would not be, and after much hesitation 1 finally consented to your proposition, and 
 you placed such a Furnace in my house. I now desire to say to you that I was wrong and you were right, and I want further to say, 
 that from October 13, to April 13, during a Dakota winter of unusual seveiity, I have used in heating my house of ten rooms, just five 
 tons of coal. Every nook and corner of the house has been warm, no dust, no coal ashes, no gas, no litter about the room in filling the 
 Heater or removing the ashes, a good natured wife and a happy family. My head you know, Mr. Hill, is getting somewhat white, and 
 I should have knowledge of many facts derived from large experience, but you have demonstrated to me how to live comfortably,

 warm with three stoves. Our main store is 20 x 80 feet, with a side room 12 x 60 feet, and a room up stairs, 20 x 50 feet. All this 
 surface is now heated to our satisfaction, and for the amount of heat and comfort we now get, the amount of fuel consumed is but a 
 trifle more. We are using now about ten tons of coal during the season.

 Gentlemen :—It gives me much of pleasure to advise you that the No. 18 Generator placed in my home, No. 515 East Fayette street, 
 this city, has given me entire satisfaction, during the past seven years which it has been in constant service, and I might add, without a 
 cent of expense for repairs. With the Positive Heat Attachment, the Generator accomplished what other heater men would not guarantee 
 me, namely, to heat a basement dining-room on a level with the Heater, and a bath-room on second floor, in the northwest corner of the 
 house. We cordially and cheerfully recommend the improved system of heating, as furnished by the Kelsey Generator. 
 
 Very truly yours, Wm. J. Morrell.

 Gentlemen :—I had placed in my cellar, by your Agent in this town, Mr. A. V. Fletcher, a No. 14 Generator. I have a cottage-house 
 of seven rooms and bath room, all of which have been heated in a thoroughly satisfactory manner. The doors of each room are open all 
 the time, making a uniform heat all over the house. During the four years I have used the Generator, I have averaged to burn 3% tons 
 of coal per year. I believe it to be the most economical Heater on the market, and gladly recommend it to anyone thinking of placing a 
 Heater. Wishing you success, I am, Fraternally yours, J. T. Newell,

 Dear Sirs :—It is a pleasure for me to write you a few lines, as to the results shown by the No. 21 Kelsey Warm Air Generator 
 placed in my home last season. In its workings, I have found it cleanly, economical, and requiring but little attention. My house 
 throughout has been heated most comfortably, and with the very least variation possible in the temperature, day or night; we are 
 especially delighted with the Hot Water Attachment in the Heater, in connection with a 40-gallon Kitchen Boiler, standing about thirty 
 feet from the Generator, and during the entire season, there was an abundant supply, day and night, of water that was really loo warm 
 in which to bathe. 
 
 Our home is one of eight rooms and bathroom, besides upper and lower hall, and I might add, the hall we use really as a sitting 
 room, and it is 24x14 feet in size, with stairway leading to large upper hall, and connected with the library by a large, open arch, and to 
 make comfortable such residence, requires a good Heater. 
 
 With the two Furnaces which we were using previous to placing your Generator, we were obliged to supplement with the use of the 
 grate in the hall, which grate we did not use once this last season, after starting your Heater. 
 
 In closing would say, we are perfectly satisfied with your Generator, for both cold and mild weather, and frequently speak of my 
 “luck” in overhearing one of your customers describe his success with one in his home in Elyria, which led to a search on my part, until 
 I found your address. Very truly yours, Florizel Smith.

 Dear Sir :—When I was negotiating with Mr. J. R. 
 McLaughlin, for the purchase from him, of a residence on 
 King ave., I found that he had contracted with you, for 
 placing therein, one of your No. 24 Kelsey Generators. 
 I protested, as at that time I was prejudiced in favor of 
 Hot Water Healing As an inducement for me to make the 
 purchase, Mr. McLaughlin agreed, that if after I had given 
 the “ Kelsey ” a fair trial, I should be dissatisfied with it, he 
 would replace it, at his own expense, with a Hot Water 
 Furnace and radiators. I made the purchase, have now used 
 the Kelsey Generator two winters, have given it a severe 
 test in all kinds of weather, and I must express for it my 
 entire satisfaction. In its management, it requires but little 
 attention, and I think it preferable to steam and hot water 
 heating, on account of economy in fuel, and the excellent 
 ventilation it affords.

 Gentlemen :—It gives me great pleasure to add my testimonial, as a user of the Kelsey Generator. I am using a No. 18, the fifth 
 season, and must say, I have had entire satisfaction. I have never used more than seven tons of hard coal per year, and have thoroughly 
 
 heated ten good-size rooms to 70 degrees, in all kinds of weather. As regards durability, I have not expended one cent for repairs, and 
 
 believe there is nothing made as durable as the “ Kelsey.” I also believe the quality of warm air is equal to that of water heating.

 Gentlemen :—The Kelsey Generator put into our house, a few years ago, has given perfect satisfaction, and is far ahead of any Hot 
 Air Furnace, of which I can obtain any information. With the thermometer 15 degrees below zero, we can heat any or all rooms in the 
 house, to 90 degrees, if we wish to do so. We would not exchange it for all the hot water or steam plants in the country. Our house is 
 
 a hard one to heat, and furnishes a severe test for your Generator. We feel that we cannot say too much in its praise.

 Gentlemen :—Last summer, your Agent, Mr. J. C. Jones, placed in our home, one of your No. 18 Generators, and the same has more 
 than met our expectations. It has heated our entire house, of four rooms down stairs, and four rooms and a bath-room up-stairs, and 
 at no time have we had trouble in keeping our entire house comfortable. The quality of the air we find quite different from that of the 
 ordinary Hot Air Furnace. We use the Poccahontas soft coal, and only used five tons, with a continuous fire, from October 151I1 to 
 April 15th. The price of Poccahontas coal in this city, is $3,50 a ton. At no time was our fire out during the winter. The Kelsey 
 Generator, with the Poccahontas coal, beats any heat that I have been able to find, and is a labor and money-saving Heater. I will do 
 what I can to place your Generators here, for I know they will give satisfaction. Yours respectfully, 
 
 W. H. Mazey.

 Gentlemen :—I have had two different makes of Furnaces for heating my residence, but neither were satisfactory, as in coldest 
 weather it was impossible to keep the house warm, and I decided to try Hot Water Heat, when you claimed that a No. 21 Kelsey 
 Generator would heat my whole house, and give us fresh, out of door air to breathe, instead of the close air usually breathed in rooms 
 heated by steam or hot water, and you were allowed to put it in on trial. Your claims have been fully realized by us, and my family are 
 very much pleased with the Generator, and cannot say too much in its praise. The amount of fuel used, to keep the whole house 
 comfortable, is but very slightly more than the furnaces required, to imperfectly heat a small part of it. 
 
 Yours truly,

 year I have had mine in use, and it has never failed to give good 
 results, even in severest weather. My house of nine rooms is comfortably and easily warmed throughout, with your No. 2t Generator 
 also I have the Hot Water Attachment, which supplies at all times, hot water for Rath and Laundry purposes. I use Natural Gas for 
 fuel, and the amount required to run it does not exceed that consumed in a good sized stove. My fuel bill last year was $15. 75 - The 
 Kelsey Generator is, without doubt, the Heater desired for Natural Gas as fuel.

 Dear Sir :—Ir affords me great pleasure to advise you how much we are pleased with the No. 24 Kelsey Warm Air Generator which 
 you placed in our residence, in Colonial Park. Our residence is located on very high ground, overlooking the city, and is exposed to 
 heavy westerly winds. The Generator has been in use three winters, heating three floors, including the halls, practically twelve rooms. 
 The air throughout the house is pure and mild, like balmy summer heat. The quantity of coal consumed has been a little less than nine 
 tons each season, from the middle of October, until the first of May. The Generator is easily controlled, and we rarely open the direct 
 draft damper. Combustion is perfect. Only in extremely cold weather, has it been necessary to open the registers in our sleeping rooms. 
 
 1 he heat seems to be especially adapted to the growth of plants. We have a great variety of palms and potted plants, which grow 
 and bloom in almost tropical luxuriance. We are thoroughly satisfied with the record of the Generator, and feel that we cannot say too 
 much in its praise. Most sincerely yours,

 concluded, on the strength of iis many apparent qualities, and testimony of those using it, to place in my new residence, a No. 24, which 
 they guaranteed would heat my house of sixteen rooms, front and back halls, and two bath-rooms, and the result of one winter’s use is 
 extremely satisfactory, both as to heat, and the ease with which it is controlled. Very truly yours,

 considering the amount of space heated, and also the Hot Water. 
 
 One feature of the Heater which we have especially enjoyed, and that is, no matter how warm the house might be, the air is never 
 burned or uncomfortable, always clear and mild. This Heater will never cause headaches.

 out. After using the Generator four years, in which we have never used more than five tons of coal, during any winter, I am happy to 
 state, that the flues, as well as all other portions of the “ Kelsey,” are, to all appearances, as good as new ; we have never been obliged 
 to repair the same. Wishing you continued success with the “Kelsey,” such as you deserve, I beg to remain,

 MR. A. A. HARE, Agent for Kelsey Warm Air Generator, Detroit. Mich. 
 
 Dear Sir :—It gives me great pleasure to comply with your request for a written testimonial in regard to the Kelsey Generator. 
 
 When I contemplated building my fourteen-room house, at No. 196 Iroquois Ave., I had fully made up my mind to put in a hot 
 water heater, and thought nothing could change my mind to have anything different, but upon hearing about the good points and work¬ 
 ing qualities of the Kelsey Generator, its simplicity, how quickly and economically a large house could be heated with the system, and the 
 pure air that one derives therefrom, I thought it worth while to investigate, which I did personally, and found to my entire satisfaction, 
 that wherever the system was in use, the parties were more than pleased, so I concluded to change my plans about a hot water healer, and 
 place a Kelsey Generator, with which I am perfectly pleased. I was more than surprised to find how easy and economical it was to heat 
 my large house to 75 degrees in the coldest weather, as it is entirely exposed, and to find that some of my friends, with very expensive 
 hot water heaters, could not get their houses heated to 68 degrees. 
 
 I also wish to state, that where we formerly lived, we used an ordinary hot air furnace, and with the very best of care, could never 
 raise any plants or flowers in winter. In my new home, and with the pure air from the Kelsey Generator, we have raised the most deli¬ 
 cate plants and flowers this winter. 
 
 I can truthfully recommend the Kelsey Warm Air Generator to be the best, most healthful and economical heater in the market. 
 
 Yours very truly, Frederick W. Young,

 Dear Sirs :—Replying to your favor of 28th February, will say, that this is the fifth winter I have used the Kelsey Generator in my 
 house, and it gives me as good service as when first putin. I burn anthracite coal in the Heater, and there has been absolutely no escape 
 of gas from the heat flues. There is no trouble whatever in keeping it clean. Four or five of my neighbors have put in the same make 
 of Heater, and express themselves as much pleased with it. I am in no way interested in the manufacture or sale of the Generator, but 
 in my case it has given such excellent satisfaction, that I am glad to inform others of the fact, if they are interested in the subject. 
 After years of experience with the Kelsey Generator, I should buy no other, in case I would find it necessary to buy another Heating 
 Apparatus. ' Yours truly, F. S. Oakes.

 Gentlemen :—The No. 21 Kelsey Generator which we placed in the residence of Mr. H. L. Ward of this city, accomplished more than 
 we expected of it. We took out a furnace of a first class make, which had failed to do the work in a satisfactory manner, although it 
 had a fire-pot of a larger diameter than the No. 21 “ Kelsey.” We had a northeast corner room on the second floor, which had been very 
 difficult to heat with the old furnace, and we placed in it 65 feet of direct water radiation, and connected it to the water-front of the Gen¬ 
 erator. The piping had a horizontal run in the basement, of about 30 feet, and then a vertical rise through a rear hall, close to an outside 
 door, in a cold and exposed place. The results were more than satisfactory, in fact we had too much heat from that radiator ; the water¬ 
 front would have easily carried as much more radiation. Yours truly, W. H. Buckley & Co.

 Dear Sir :—The Kelsey Generator which you placed in my home in this city, last fall, has given unqualified satisfaction. The house 
 is a single, two-flat frame house, well built, but quite exposed ; the Generator heats the second floor and one attic room. We heated the 
 entire second floor, of five rooms and a bath-room, all last winter, heating also the one attic, and using the kitchen stove for cooking 
 purposes only. The rooms were kept at about 70 degrees. The fire did not go out, except once or twice in the late spring, and we used 
 not quite four tons of coal in the Heater. 
 
 There was no odor of gas, and the air was at all times fresh and pure, being taken wholly from out-of-doors. 
 
 This experience simply confirms my previous belief in the unexcelled qualities of the Generator, and the very superior way in which 
 the work of setting the same, and piping, is done by yourself. 
 
 This Generator herein mentioned, is No. 14 “ Kelsey.” Yours very truly, W. D. Johnson.

 Dear Sirs :—The No. 24 Kelsey Generator which you 
 placed in my house, No. 545 Beacon St., has given good 
 satisfaction. I can warm my house nicely, the air from the 
 Generator is good; no gas in the rooms. 
 
 You remember when I was looking for some heating 
 arrangement. I said Furnace heating had gone by; now I am 
 convinced that the Kelsey Generator is the best Heating 
 Apparatus in the market. We heat to a uniform temperature 
 eight rooms. The rooms are large, and the house is exposed.

 Dear Sir :—In reply to your inquiry would say, I have 
 used a No. 18 Kelsey Warm Air Generator in my home for 
 two years, and am perfectly satisfied with it. I believe that 
 it will heat more space, with less coal, than any Heater 
 made, and it is as easy to run as a kitchen stove. I do not 
 believe there is a Hot Air Heater made, that comes any¬ 
 where near the “ Kelsey Generator", in points of excellence 
 and economy. Respectfully Yours,

 Dear Sir :—I take pleasure in stating that the No. 24 Kelsey Generator which you placed in my house, is giving me perfect satisfaction. 
 The house is one of twelve rooms, standing alone, and very much exposed notwithstanding which, I have no trouble in maintaining a 
 temperature of 70 to 75 degrees, with the thermometer at zero. I am also particularly pleased with the quality of the atmosphere in the 
 house, not having the extremely dry, parched air, which troubled us with another Furnace.

 Gentlemen :—Your favor of 23d received. In reply, would say, we have used Kelsey Generators in each of our homes since 1890. 
 The castings are all in good shape, as far as we can ascertain. We made a thorough examination of them last fall, and no castings 
 needed any repairs, or showed much wear. We believe that the sectional fire-pot, such as is in your Generator, is the best fire-pot made.

 as demonstrated by my experience, are : I. The large volume of warm air which it supplies. 2. Economy. During the past winter, 
 beginning early in the Fall, and continuing until late in the Spring, it has warmed seven rooms on two floors, besides large halls and 
 bath-rooms, consuming but five tons of stove size coal. Yours truly, George H. Allen.

 Dear Sir :—It is a pleasure to be able to testify to any article that is worthy, and has true merit. I put a No. 18 Kelsey Warm Air 
 Generator into my store in the winter of 1896, and found that it warmed my store with two-thirds the coal, and much better than the 
 three stoves I had formerly used, saving work and dirt. This last fall I had a “ Kelsey ” placed in my residence, and can say that it is 
 perfection, so far as heat, comfort and cleanliness goes. I can honestly recommend the Kelsey Generator, as being the “up-to-date ’ 
 Heater in every respect. George F. Hutchinson.

 Gentlemen :—The Kelsey Generator which you placed in my home in the Fall of 1896, has been used during the last two winters, 
 with a great degree of satisfaction. Our occasion for removing the furnace which we had in use before placing your Generator, was 
 from the fact, that we could not heat our basement dining-room, on the same level with the furnace, or the bath-room, which required a 
 long, horizontal pipe, but now, by the aid of your Positive Cap Attachment, we have our dining-room comfortably warmed, and the 
 bath-room, which required a pipe fifty-two feet long, in the cellar, is as warm as we could wish. We find the Generator very economical, 
 easy to manage, and free from gas and dust. Very truly yours, George W. Youmens.

 Dear Sir :—The No. 24 “ Kelsey Generator” which you placed in our residence on Vallamont has pleased us in every way, it being 
 a powerful heater and emitting no gas or dust into the rooms above. Another feature that greatly pleased us, is the fact that it sends 
 the heat through the long as well as the short pipes. The heater is very easy to control, and from the fact that the smoke-pipe never 
 has become so warm but that you can place your hand on it, shows conclusively that the long, down draft of the heater extracts all the 
 heat generated from the fuel that is consumed, before leaving the heater and going to the chimney. The atmosphere in our home during 
 the past winter has been delightful, and we would not exchange the “ Kelsey ” for any other heating apparatus on the market.

 Gentlemen :—Last fall I placed a No. 24 Kelsey Generator, to heat my house containing six rooms on the first floor, and seven rooms 
 on the second floor. The Generator has given entire satisfaction. Last winter my home was heated better than it had been for five 
 years, and I used fully one-third less fuel than I did in any one of the five previous years, in a furnace of standard make, which I had to 
 do the same work. I can recommend the “ Kelsey” as a first-class Heater.

 Dear Sirs :—The Kelsey Generator which you placed in my house last fall, has given perfect and complete satisfaction in all 
 respects. The distribution of the heat has been even and abundant throughout ail rooms of the house, the quality of the heat has been 
 excellent, not overheated, but fresh and pure, and at all times free from dust and gas. The Generator is easily regulated, by a perfect 
 system of drafts and dampers, operated from above, so that it can be made to respond with heat, quickly or slowly, as desired, and the 
 Heater is economical in the use of fuel. I believe there is no better Heater made, and heartily recommend it.

 has done, both in consumption of fuel and results of heating. We have a ten-room house, upper and lower hall ; all rooms are open 
 and thoroughly warmed. We find more difficulty in keeping the temperature low, than in having it too high. I do not hesitate in 
 recommending the “ Kelsey” to anyone wishing an economical, strong Heater. From my experience, and what I know of the Furnaces 
 in my immediate vicinity, I am thoroughly convinced that I would buy no other Heater than the “ Kelsey.”

 Gentlemen :—Replying to your inquiry, as to how I liked the Kelsey Generator which you placed in my residence, in the fall of 1896, 
 would say, I had been using a large furnace, of a standard make, for heating my house, for a number of years, but we never received 
 sufficient heat from the same, and were inclined to put in Hot Water, but considering Hot Air the most healthful, and liking the 
 principle of the Kelsey Generator, I made the change, and I have had an abundance of heat, even in the coldest weather, running the 
 Heater nearly all the time, with the front draft closed, and check-damper open, with scarcely any waste of fuel, and the air in the house 
 is noticeably pure, and in marked contrast with the houses I visit, w'here Hot Air Furnaces are used.

 Gentlemen :—In the fall of 1S97, I had Mr. George H. Stibbs, of No. 50 Church St., this city, place one of your No. 16 Kelsey Gener¬ 
 ators in one of my houses. At different times I have used the ordinary Hot Air Heater, also Hot Water Heater, and Steam heat, and I 
 am now prepared to say that your Generator is far ahead of any of them, in every particular. 
 
 The points in my Kelsey Heater which I have found to be of superior excellence, are these: The heat supplied is pure and delight¬ 
 ful, and there is an entire absence of any odor of gas. No dust or ashes ever penetrates to the rooms, when the Heater is shaken, or at 
 any other time. It is a powerful Heater, and at the same time very economical. It is very simple to handle, and regulates to perfection. 
 This Generator is by far the best Heater I know anything of. and it has given me such perfect satisfaction and comfort, that I send you 
 this letter, v’hich is entirely unsolicited, and you have my peimission to rrake such use of it as you desire. 
 
 Yours truly, Henry D. Mildeberger.

 Gentlemen :—I have used a No. 18 Kelsey Generator for the past two winters, and am so well pleased with the results obtained in 
 heating my residence, that I would not part with it, for twice the amount paid for putting it in, and again use the largest size stove, of a 
 standard make, which I previously used in heating, (or trying to heat) five rooms. With the “ Kelsey ” Generator, I have heated six 
 rooms to 70 degrees in all kinds of weather, while the air was fresh and pure, as I am using mostly outside air, and I have used only 
 four and a half tons of coal each winter. I can heartily recommend the “ Kelsey ” to anyone wanting an A 1, Heater.

 KELSEY FURNACE CO., Syracuse, N Y. 
 
 Gentlemen :—Before leaving our home, as we shall, Friday of this week, for a three month’s sojourn in California, I wish to express to 
 you the very great satisfaction which we have derived from the No. 30 Kelsey Generator which you placed in my residence in this city, 
 about eighteen months ago. 
 
 It has, during all of such period, heated our house most delightfully, in fact better than I thought it possible to have so large and 
 exposed a residence warmed, by any means whatsoever. Steam heat is so destructive to finely finished wood-work in a residence, that 
 while it was recommended and advised to me, as being the only proper system to be installed for making comfortable our residence, I 
 was tempted to try your Heater, and my election in its favor has always been a source of much satisfaction to me, as aside from the fact 
 that we are able to heat all parts of our large residence, as perfectly as it could have been by steam, we have had furnished to the same, a 
 quality of heated air far more agreeable than steam heat. 
 
 The exact space which we have heated with the No. 30 Generator is as follows : 
 
 Parlor, 21 x 26 ft., rear parlor, 16 x 25 ft., drawing-room, 24 x 24 ft., dining-room, 15 x 23 ft., library, 13 x 13 ft., hall, 8 x 29 ft., hall 5 
 10 x 18 ft., all 11 ft. ceilings. A corresponding space on the second floor, only subdivided into two more rooms, and all of such second 
 floor space having 10 ft. ceilings. 
 
 I should mention in connection with this, that there is a well running to the third story, opening into a room about 20 x 30 ft. This 
 is always hot. This well is made by the winding of the stair case from the first to the third story. 
 
 My house is always entirely thrown open, using nothing but draperies on our first floor. 
 
 The fact that we are heating this amount of space, with this one Heater, which has in connection with it 17 heat conducting pipes, 
 and are doing such heating with an amount of fuel that is less, by one-third, than it would seem possible, I feel that you are most justly 
 entitled to this letter, if it can in any wise be of service to you. in interesting others who have large residence dwellings to have made 
 comfortable. Very respectfully yours, Charles P. Burk

 Gentlemen :—I have used one of your No. 21 Generators in my residence for the past four (4) years, and it has given me complete 
 satisfaction. I have heated ten rooms constantly, from early fall until late spring, using nine tons of fuel. 
 
 I can cheerfully recommend the “ Kelsey ” as a perfect and economical Heater. Its furnishing large volumes of warm air, instead 
 of small volumes of hot air, speaks strongly for it, from a hygienic standpoint.

 Gentlemen :—The No. 18 Kelsey Generator which I bought of you in November, 1896, has been used two winters, and I wish to say 
 the results have been most satisfactory. My house is an old one, having been built about thirty years, yet we keep six, and sometimes 
 seven rooms, as warm as we wish. There was one morning when the thermometer was 30 degrees below zero, but we had our house up 
 to eighty, without crowding the Heater to its full capacity. We had a long, cold Spring that year, and I used seven tons of coal during 
 the season. Had I used stoves, we should have required to keep three of them in operation, besides the cook stove, but, owing to the 
 Generator, we do not have to burn as much fuel as formerly. I think if I had a new house, I could heat the same space on four and one- 
 half, or five tons of coal per season. I have run Furnaces before, but give me a “ Kelsey Generator,” every time. 
 
 Yours truly, A. R. Goddard.

 Dear Sir :—The Kelsey Warm Air Generator which you placed in my residence in the fall of 1897, and which the very cold weather 
 of the past winter has enabled me to give a severe test, has proven entirely satisfactory. First, as to the temperature and condition of 
 the warm air delivered to the rooms, and second, as to the very economical consumption of fuel. I have had experience with a number 
 of Warm Air Furnaces, but am pleased to say that the Kelsey Generator is the simplest and most satisfactory Heater I have ever seen. 
 From a mechanical standpoint, the construction of the Kelsey Generator, in my opinion, is perfect, as it admits of an independent warm 
 air chamber at the Heater, for each warm air delivery pipe throughout the house, and as this peculiar construction is very similar to a 
 Hot Water Heating Apparatus, you might properly call the Kelsey Generator a “ Warm Air Boiler,” providing a positive warm air 
 delivery system. 
 
 Yours truly, Charles L. Coffin.

 Gentlemen :—I have been heating my residence, containing eight rooms, during the past two winters, with one of your No. 18 Warm 
 Air Generators, and I have no hesitancy in saying that I consider it far in advance of any Heater on the market. I have made a thorough 
 investigation of furnaces, and am satisfied that the Kelsey Generator consumes less coal, and radiates more heat, than any furnace in use. 
 
 We have long and severe winters here, and with a No. 18 Generator, properly managed, four tons of coal is all that is required. 
 Last winter I used four tons, and the winter before only tons. 
 
 Prior to the time I placed your Generator in my residence, our house plants were sickly and sallow in appearance, but since we have 
 been enjoying the genial, healthy atmosphere furnished by this Generator, they have been thrifty and healthy. 
 
 I shall be pleased at any time, to recommend your Heater to any one who contemplates putting in a Heating Apparatus. 
 
 Cordially yours, C. W. Hodgkinson.

 Gentlemen : - It affords me great pleasure to bear testimony to the very excellent heating qualities of your Kelsey Generator. I have 
 three of them in use, one which has been in my own home some four or five years, and two others located in tenant houses, for two 
 years, all three working to my entire satisfaction, and to the satisfaction of the tenants. They are easy and simple to take cate of, and 
 distribute the heat more evenly than any furnace I have used. In my own home, I have been able to conduct the heat to a distant room, 
 which I have never been able to heat comfortably, with any other Heater, but have accomplished it with the “ Kelsey,” without taking the 
 heat from other rooms, or closing registers, to force the heat, as I have been compelled to do with other furnaces. The fire-pot being 
 composed of tubes, gives more radiating surface to the same diameter, than any other Heater. 
 
 Respectfully yours, M. Ames.

 have plenty of heat to spare. We heat a parlor, 11 x 13, dining-room, 12 x 13, sitting-room, 14 x 15, bed-room, 12 x 14, and hall down 
 stairs, also three bed-rooms up stairs, 11 x 13, 12 x 13 and 12 x 14. Our home has been delightfully heated in the coldest weather, and 
 have used just nine tons of coal in two years. The smoke-pipe and casing on the heater are always cold. 
 
 My sister has a houseabout the same size, and has used about the same amount of fuel in her No. 18 “ Kelsey.” We find theatmos- 
 phere pure, no wood-work drawn or checked, and the plants thrive beautifully. Yours respectfully, H. T. Saberson.

 Dear Sir: —It affords me pleasure to inform you that the Kelsey Generator, No. 30, which you placed in St. John’s church, this city, 
 in the fall of 1896. has given the church people the best of satisfaction. 
 
 The church has at all times been heated to the comfort of those attending worship there, and on occasions, that has been done under 
 very unfavorable weather. On the coldest Sunday of the past winter, when the thermometer ranged below zero all day, the church was 
 comfortable at the 7:30 o’clock service in the morning, remaining so all day, until the evening, when the heat became uncomfortable, so 
 much so, that the Rector asked to have a window opened. A Heater which can produce such results in this cold climate, is certainly 
 worthy of recommendation. Yours respectfully, F. J. R. Clarke.

 Gentlemen: —I have used the Kelsey Generator in my residence for four years. I am very much pleased -with it, and would not be 
 without it for twice its value. It is very economical, in regard to fuel. 
 
 My house is large consisting of 13 rooms. It takes about six or seven tons of coal to heat the house from September until May. I 
 find it entirely free from dust and gas, furnishing an ample supply of pure, warm air. In fact the Generator has given me perfect satis¬ 
 faction in every respect. 
 
 During this period, there has been no expense for repairs, which I think is quite a consideration.

 the same was placed, without any let up whatever, and at no time was it used to its full capacity, and it always furnished the heat 
 required. 
 
 After the trouble which we had with the Heater used previous to placing the “ Kelsey,” we were in doubts of your being able to 
 carry out your agreement, with the Kelsey Generator, but since using the “ Kelsey” we are convinced that it is all you claim for it, and 
 we feel satisfied with it, and would use no other at half the price. We heartily recommend the “ Kelsey,” to anyone desiring a first-class 
 Heater. Yours truly, Fred G. Zeibig,

 “It works beautifully in every respect.” He makes, I think, a fair statement of its merits.

 Gentlemen :—During the past five years, we have had in use in Franklin Academy, one of your No. 24 Generators. It has been used 
 to heat five rooms, including two large study rooms and one good sized chapel. The chapel is located on a level with the Heater, and by 
 the aid of your Positive Attachment we have been able to warm this, and the recitation rooms on the second floor at the same time. The 
 Generator has taken the place of five stoves, heated more rooms, and used less coal. 
 
 For two weeks of zero weather, the study rooms were made comfortable, even in the farthest corners. The working of the Generator 
 is satisfactory in every respect. Very truly yours,

 The Board of Education of this village has had in use in its School Building for the past six years, a Kelsey Generator, which has 
 given the best of satisfaction. We think it requires a minimum amount of fuel for the work it does, and would recommend the Kelsey 
 Generator to any School Board that contemplates putting in a new Heating arrangement. Your respectfully,

 Gentlemen :—It is with pleasure that the School Board of Crown Point, Ind., can speak a good word for your Generator. We have 
 used one of your Generators for two years, and put in two more new ones last Fall. We find they do better work than the old ones, of a 
 different make did, with fully one-third less coal. We have one more old one to throw out, and that will be replaced with a Kelsey.

 Dear Sir :—It affords me great pleasure, to advise you of the general efficiency of the No. 21 Kelsey Generator which you placed in 
 St. Paul’s Church, in this city, in 1896. We have a small furnace, of another manufacture, which has always been required, previous to 
 installing the Kelsey Generator, but during the past winter, we have used the “ Kelsey ” alone, many Sundays, and it has satisfactorily 
 heated the entire church building, containing over five hundred sittings. The consumption of coal has been less, by 25 per cent, than 
 for any previous season, during my experience. I can only add, that we are greatly pleased with the decision of our Committee on 
 Church Property, in selecting a “ Kelsey Generator,” and remain. Very truly yours. Robert II. Waters, 
 
 Treasurer.

 Dear Sir :— I am pleased to inform you of the splendid results obtained from the Kelsey Generator which you placed in the 
 Congregational Church of this City. The Auditorium room contains 88,775 cubic feet, and is heated by the No. 30 Generator, and it is 
 so arranged, that we can also heat the basement dining-room, which is on a level with the Generator. We also heat the reception-room, 
 containing 2,850 cubic feet, by means of a “ Positive Attachment” connected with a pipe from the Generator, running a distance of 35 feet. 
 
 We also heat the Chapel, which contains 22,815 cubic feet, with a No 24 Generator. It also has a large pipe from the same, which 
 can be used to assist in heating the Auditorium. We heat the children’s room, which contains 4,000 cubic feet, by a “ Positive Attach¬ 
 ment” connected by a pipe 26 feet long. Also a Vestibule, which no one supposed could be heated, but which is as warm as any part of 
 the Church and has also in connection with it, a “Positive Attachment" from the No. 24 Generator, the pipe to which is 35 feet long. 
 
 The only objection so far, that we could possibly offer, is that we have had more heat than we required ; aside from that, I have 
 heard no complaints, and everyone seems proud of our Church, and the manner in which it is heated. 
 
 Yours respectfully,

 Gentlemen :—In the winter of 1893, our Church Committee were obliged to remove a very large furnace, that would not heat the 
 church satisfactorily, substituting therefor, a No. 24 Kelsey Warm Air Generator. Our church is large, and the heat conducting pipes 
 are very long, but the building has been satisfactorily warmed at all times. The air is pure, the Heater economical in the use of luel, 
 and we would cheerfully recommend it as a first class church heater. Signed.

 It gives me pleasure to say that the Generator has given most perfect satisfaction in every respect. Have never detected the first

 Dear Sir :—The No. 30 Kelsey Generator which you placed in the new Parish house of St. Paul’s Church, about two years ago, has 
 proven entirely satisfactory in its work. We have a hall, 30 x 40, and 14 feet high, of nearly two hundred seating capacity, a large 
 choir-room, besides the hallways, rector’s office, music library, and toilet rooms, in all over 30,000 cubic feet of air space, which has been 
 kept at an even temperature. The Kelsey Generator was selected by the donors of the building, after the most searching inquiry, into 
 the merits of a large number of Heating Apparatus presented to their attention, and we have cause to congratulate the Pasish on its 
 choice. I am very glad to be able to speak favorably of your work, and remain, Yours truly,

 Dear Sir —I am glad to contribute my testimony in favor of the Kelsey Warm Air Generator; after sixteen years of trials with 
 furnaces of different kinds, I must decide in favor of the Kelsey Heater. Two years ago, we placed in our Church building, a No. 18 
 Kelsey Generator, and it has proven a great success in heating the Ladies’ Parlor, Chapel and large hallway. Previous to placing the 
 Generator, we required to have two large furnaces running, in order to warm these rooms. The “ Kelsey ” has kept these rooms all warm 
 and comfortable, without the aid of any furnaces. Previous to getting the “ Kelsey,” we consumed from 30 to 35 tons of coal per year. 
 This last year we reduced the quantity to 20 tons ; this reduction will, in a few years, pay for the Generator. I must say, the “ Kelsey ” 
 is the most economical, and the easiest to run, of any Heater, giving perfect satisfaction in every way. 
 
 Respectfully yours,

 Dear Sir :—This is to certify that we have placed one of your Kelsey Generators in the basement of the Emory M. E. Church, on 
 North Highland Ave., East End, Pittsburgh, and have used it for nearly three years. The church is a very difficult one to heat, owing 
 to its construction, but we have had very good satisfaction with your Heater, and can recommend it to parties for use in large buildings. 
 The Generator was arranged to heat not only the auditorium, but also the Sunday-school room, and the infant class-room. The pipe 
 leading to the infant class-room is 20 inches in diameter, and 73 ft. 9 inches long, with six angles. By use of your Positive Cap Attach¬ 
 ment, we find it possible to carry heat even this distance, with your Generator.

 Gentlemen ;—‘In the winter of 1892, we had two of your Generators placed in our church building, to heat the Sunday school 
 department. 
 
 The room is large, and has a gallery on three sides, and I think would be considered a hard room to heat. The Heaters have been 
 in constant use since they were put in, and I am glad to be able to say that they have given good satisfaction. 
 
 During the six years the Generators have been in operation, we have not been required to spend one dollar for repairs, except new 
 smoke-pipe. I most cheerfully recommend your Generator.

 Dear Sir :—Over a year ago, you placed in our Church Building, a No. 24 Kelsey Generator, and it is with much pleasure that I 
 heartily recommend such Heater. The Church is one of those old fashioned, square edifices, of more than a hundred years ago, with 
 very high ceiling, and a difficult one to heat. For many years, we have used two Furnaces, trying to heat the same. Since your 
 Generator has been placed, it has done what the two Furnaces failed to do, and has accomplished the work in a very satisfactory manner. 
 It was forced to do double service, burn two days instead of one, and yet it called for but part of an extra ton of coal, more than we 
 formerly used. We have nothing but the highest commendation to offer, in reference to the “ Kelsey.” 
 
 Yours truly, T. James MacFadden, Pastor.

 Gentlemen :—Two years ago, we purchased of your Agent in Glens Falls, N. Y., a No. 24 Kelsey Generator for heating our Church. 
 The main part is 40 x 45 feet, with 20 ft. ceiling. The Sunday school room at rear, is 15 x 40 feet. This room is situated on a level with 
 the Heater. We have had no trouble in heating both rooms, even in the coldest weather, without crowding the Heater. As the Church 
 is not very warmly built, we consider it very economical in use of fuel, as we have not used over seven or eight tons of coal either winter.

 C. M. BIRDSALL, Agent, Kelsey Furnace Co. Wilmington, O., May 20th, 1897. 
 
 Dear Sir :—The Committee on Light and Heat, of the Friend’s Church of Wilmington, after a careful examination of all the 
 propositions submitted for heating the Church, accepted yours, with two Kelsey Generators, as being, all things considered, the best 
 adapted to our wants. The results secured during the past winter have fully justified our choice. The Church has been maintained at 
 an even, uniform and comfortable temperature in all sorts of weather. 
 
 The Thermometers hung in different parts of the Audience-room, and in adjoining rooms, and show a remarkably even distribution 
 of heat. 
 
 The Ventilation secured by your System seems perfect. These results have been attained with a small amount of Poccahontas coal, 
 and with a minimum amount of attention to the Furnaces. 
 
 So far as the committee are able to judge, they regard the Kelsey Generator as satisfying every reasonable expectation that can be 
 made of the same. 
 
 The Church is used for six regular services each week, besides an additional song service once each month, the regular quarterly 
 
 meeting every three months, the weekly meeting of the Ladies Aid Society, and a large number of Committee and other meetings. 
 
 The Church in size, is 40x90 feet, ceiling 31 feet in Auditorium room, 9 foot basement under whole, and 9 Tower rooms, used for

 My Dear Sir :—In the autumn of 1895, you placed one of your “ Kelsey Generators” in the Chapel of the Central Presbyterian 
 Church, corner of Third and “I” Sts., N. W., and a few weeks later you placed one in my reiidence, No. 517 Fourth St., N. W. 
 Sufficient time has elapsed to enable me to express an impartial and intelligent judgment of the merits of these Generators. Although 
 heretofore we had two furnaces for heating the Chapel, we have never until now been comfortable in extreme cold weather. In my own 
 residence, the “ Kelsey Generator” furnishes with ease, from 10 to 20 degrees more heat, with the same fuel, than did the old furnace. 
 For volume of heat, purity of air, economy of fuel and ease of management, I know nothing of its kind that can be compared with the 
 “ Kelsey Generator.” Yours truly, A. Pitzer, Pastor,

 dollar’s worth of repairs from you, during the past five years, for repairing defective parts in your Generator. 
 
 Have three or four jobs sold now, that will be placed as soon as the cold season is over. Competitors have worked their photograph

 Gentlemen :—About five years ago, while passing your place of business in Syracuse, I noticed one of your Kelsey Generators on the 
 sidewalk, and stopped to look it over. I was satisfied that the Generator was constructed on superior lines, but was afraid that the price 
 would prevent its general sale. I tried one of them that year, and its work was so satisfactory, I have used a number of them since, 
 having placed twenty-six of them and in every case they are giving the best of service. I have not found the price the great obstacle to 
 sales that I had anticipated, and much to my surprise, I am selling them to a class of people who have to count their pennies, and they 
 tell me they find the extra cost a good investment, one that pays them dividends every year, both in reduced coal consumption and wear 
 and tear. The “Kelsey ” makes the dealer independent of all competition , where quality is the basis .

 ing excellent satisfaction. I have placed several of your Generators in public buildings, and find that they are all doing the work in a 
 first-class manner. Three years ago, I placed a No. 18 in my own house, which heats five rooms and two large halls, and we have no 
 difficulty in maintaining an even temperature of 70 degrees, even in the coldest weather. The consumption of coal averages about five

 in efficiency and economy of fuel. Many of them have been placed in very exposed localities, giving them a severe test, which they

 Our experience with them has been extremely satisfactory, and we consider, a Dealer who secures the Agency for these Heaters, has 
 a decided advantage over his Competitor, with customers wanting well and economically heated homes.

 Gentlemen :—I feel it a duty and a pleasure to advise with you and the 
 public generally, as to your Kelsey Generator. Having in the last fifteen 
 years sold and placed 1,683 furnaces of various makes (having sold about 
 1,200 of one pattern), two years ago I was induced to take the agency of your 
 Generator, since which time I have placed about two hundred of them in this 
 city, and they are, without exception, giving to the users the most unquali¬ 
 fied satisfaction, and I am to-day recommending them to my trade, as the 
 very best that the market affords, in the line of economical house heaters, 
 also as being infinitely superior to the ordinary hot air furnace, in producing 
 pure, wholesome heated air, free from gas and dust. Two years ago I 
 placed a No. 24 “ Kelsey ” in my own residence. No. 925 “ N ” St., N. W., 
 that I might test its merits, and speak understandingly regarding it to my 
 trade. I have consumed with such No. 24 Generator in my house about 
 twelve tons of coal each winter, whereas with the furnace which I had pre¬ 
 viously used, and which I displaced at the time of locating the No. 24 
 “ Kelsey,” I used about nineteen tons of fuel each year, thus having saved 
 during the past two years about fourteen tons of coal. 
 
 Respectfully submitted, A. S. Johnson.

 Gentlemen :—We wish to send you our testimony in favor of the “ Kelsey 
 Generator'” We have set twenty-seven of them, and have watched them 
 closely. It is really a pleasure to call upon our customers and listen to their 
 expressions of praise for the “ Kelsey." In our twenty years' experience 
 setting heaters, we have never placed one that has given such universal 
 satisfaction as yours. Very truly yours, Dye & Bresee.
