Each of these fibres is so light that it floats on water, yet so rugged that the millions of 1 years of the earth’s cooling, hardening and cracking did not break L, its slender, silk-like thread. Compared with other minerals, the aggregation of unique properties possessed by Asbestos is unparalleled. Wood burns—Asbestos is unchanged by flame or by temperatures of 1500 deg. F, Stone disintegrates—Asbestos defies erosion. Steel rusts—Asbestos is immune. Asbestos resists wear and the action of oxygen and acids, is a non-conductor of electricity, and insulates against heat or cold. Today an audience sits in a crowded theatre. It faces a curtain with the word Asbestos on it—spelling to them safety—an armor against fire. Around are bril¬ liant lights energized from distant generators through a system safeguarded by this same Asbestos. Many here live or work in buildings roofed with Asbestos. Here, too, are many housewives whose dining-tables it protects. Even the motor cars have brakes lined with this same mineral. For centuries Asbestos was but a curiosity—the mystic mineral, the paradox of ages. But today it is a recognized necessity, developed by the efforts, the cour¬ age and the resources of a business institution which, by making this curio of ages serve man, has contributed to the world’s progress and has made life safer and more complete. Had some one championed Asbestos earlier, had some one the vision and fore¬ sight to realize the possibilities of this mineral, the world today would be farther along. The Chicago fire might never have happened—indeed it is probable that 50 years hence the community fire will be a finished page as the Asbestos Roof gains ever wider acceptance. Asbestos is used as the basis for practically all Johns-Manville Building Materials. Faye Three Johns-ManvillG SoivicG to tho AichitGct, Builder and Owner T here is a distinct advantage in choosing from a line of building materials on which the responsibility for service and satisfaction is concentrated in one organization, national in scope and reputation. In this way you are assured of better service, better value and greater satisfac¬ tion all around; consequently, the best return on your purchase. The architect, builder or owner who uses Johns-Manville Building Materials enjoys this advantage in the fullest sense. Because, whether it is a square of roohng or a bale of wail insulation, it is backed by Johns-Manville Service—a service that does vastly more than merely sell you a building material, or perfunctorily apply it. It is a service that will advise you by mail or send a man from the nearest branch to assist you—that offers you the benefit of experience gained by over half a century in building material manufacture and application. We like to have the most difficult problems laid before us, because w'e can cope with them. And we know that the sound, practical advice of our engineers can be of material assistance to you. There is a Johns-Manville Branch in every large city in the country. This means that Johns-Manville Service is within easy reach of you at any time. Let this service work for you.

E very user of Johns-Manvllle Roofing is privileged to register his roofing with us by means of a special registra¬ tion blank furnished him. This means that we assume the entire responsibility for the performance of our materials and see that every Johns-Man- ville roof-owner secures the full service from his roofing that we promise for it. And this applies to every part of his roofing—because we believe that it is our duty to see that our materials in the flashings and gutters give as good service as the surface of the roof itself. In this way the Johns-Manville System of Roof Registration is even better than a guarantee for a limited term of years on a certain part of the roof—because Johns- Alanville Responsibility is behind the roof¬ ing until it has fully served up to every claim made for it.

He has materials at hand for another hut, his labor has no economic value, he has no investment or accumulation of wealth at stake. But in a great modern office building, or a factory, hotel or bank, the wealth at stake is far greater than the building’s cost—for it includes not only the contents, but the loss due to interruption of business and interference with established routine. In the heavy responsibility of protecting big investments the roof shares at least equally with side walls and foundation. If it be regarded, then, not merely as a top covering but as an integral part of the structure—in fact the portion most dangerously exposed to every attack of the elements—the importance of adequately solving your roofing problems is vital. When this responsibility of the roof is once appreciated, the selection of a suitable type becomes just as urgent as the selection of power, equipment or labor- saving machinery. It demands the same study of economic factors—first cost in its relation to the total investment, upkeep cost, insurance rates earned, protection afforded and length of service. P a (j e Six Barn of George Bundle, Danbury, Conn. .lohns-Manville (Brooks Brand) Asbestos Ready-to-lay Roofing Johns-Manvillo Asbestos Roofings T he quality of asbestos products depends not only upon the experience, skill and equipment of the manufacturer, but also upon the quality of the raw material. Since asbestos fibres vary, the correct grading and selection is absolutely necessary. Controlling every step from mine to market, combining the facilities of the miner with the expert knowledge of the manufacturer, Johns-Manville has exceptional opportunities for discriminating in selection of asbestos fibre for Johns-Manville Asbestos Roofings. This in itself is a definite manufacturing advantage. The fibres extracted from the crushed asbestos rock are graded by length and strength. For roofing fabrics we select that grade of fibres which gives uniformity of texture and the highest tensile strength. For built-up and ready-to-lay roofing these fibres are fabricated by special machinery into strong compact felts, which in turn are thoroughly impregnated with natural asphalts. The felts are then cemented together with hot asphalt either on the roof (for built-up roofing) or at the factory (for ready-to-lay roofing). There is no roof built—fiat, monitor, saw-tooth, or special design—to which Johns-Manville Asbestos Roofing in one form or another cannot be applied. P n (j e .S' f f e ii Maintonanco Cost B ecause of their asbestos base, Johns-Manville Asbestos Roofings will not rust, like metal roofs; will not rot like roofs of organic base; are not apt to crack or check because of summer sun or winter snow; will neither carry fire, absorb moisture, nor wear out quickly even in severe service. They give positive protection year after year against fire and weather at a maintenance cost so low in most cases as to be negligible. On a comparative basis of actual total expenditure—first cost plus repair cost— Johns-Manville Asbestos Roofings effect savings which represent a handsome return on the investment. That’s why they’re called the “cheapest-per-year” roofings. This low maintenance cost is due to the unchanging properties of the raw material. Asbestos, plus proper design, honest manufacture, and correct applica¬ tion. These properties are subject to no variation, nor are they dependent on any coating or reinforcement which requires periodic renewal. It is because of what is IN them—not ON them—that Johns-Manville Asbestos Roofings give such lasting protection to your property investment. Citnu. UE >U*«.Vt»««lOOO . J'D Minden, Nebr. H. W.

We put the 3-ply on our building in 1886 and for twenty years did not spend a dollar for maintenance and the roof gave good service for about 4 years more with slight repairs.

Johns-Manville Asbestos Built-Up Roofing Page Eight nL Obligation to tllQ Community T he increasing concentration of values, whether under one roof or in restricted sections of a community, causes more than a proportionate increase in fire risks. Hence every step toward fire prevention is a potential economic sav¬ ing, operating to reduce insurance rates and to avert the spread of disastrous conflagrations. Johns-Manville Asbestos Roofings are an effective barrier to roof-communicated fire. Flying brands or sparks from nearby fires die out harmlessly on a Johns-Man¬ ville Roof. This was shown at Paris, Texas, when our Asbestos Roofing on the City Steam Laundry stopped the spread of flames in that section. A.W.Mc Coy.

Dear Sirs:—In justice to yourselves and to the Asbestos Roof that you applied on the City Steam Laundry, Paris, Tex., I want to say that had it not been for the absolutely fireproof qualities of your roof the property loss in Paris would have been greater than it was. Your roof checked and prevented the spread of the fire and whilst adjoining buildings were burnt to the ground the Laundry stood the severest test that any building could be put to; blaz¬ ing timbers and shingles were blown on to this roof only to die out without affecting in any way the roofing material. After seeing the building emerge from the worst fire Texas ever suffered from we were indeed glad that when selecting the type of roof we had put quality and service before price. You are at liberty to use this letter inany wayyou mayseefit. Yours truly. City Steam Laundry^ Paris, Texas, after the Fire Johns-Manville Asbestos Prepared Roofing Page X i n e Approval by the Undorwritors T he attitude of insurance authorities toward a building material is of special interest, both because of its effect on insurance rates, and because it serves as a reliable index to the fire-resistant properties of the material in question. For this reason the results of tests made by the Underwriters’ Laboratories, Inc., are of particular importance to the prospective buyer of any building material. The Underwriters’ Laboratories are located at Chicago, Ill., and are financed by and maintained under the direction of the National Board of Fire Underwriters, the official body representing all recognized fire insurance companies of the country. At these laboratories, roof coverings of every description are tested, examined and classified according to their resistance to fire. The tests made upon these roofings are most severe and exhaustive. They are not restricted to any time limit, but are continued as long as the roofing stands up under the severe conditions of the radiant heat, burning brand and flame exposure tests described on these pages. Fig' 1—Making Radiant Heat Test The temperature of the circular plate at the lowest point of the gas furnace and on the sur¬ face of the roofing sample is approximately 1200 degrees Fahrenheit.

Page Twelve to take the base rate of insurance, may be safely put on any b u i 1 d i ng w i t h a knowl- edge that it is fire-safe to the highest degree. All Johns-Manville Asbestos Roofings are put through the tests described below and are given either Class “A” or “B” rat¬ ing, according to the construction of the roof deck and the type of roofing. Either Class “A” or Class “B” takes the base rate of insurance. Radiant Heat Test To determine how the roofing will stand up when subjected to the radiant heat from a nearby fire fanned by a breeze, a radiant heat test is made on the roofing while it is exposed to varying air currents to simulate wind. A sample of roofing is shown undergoing such a test in Fig. i. Fig. 2 shows Johns-Manville Asbestos Roofing after this test. Burning Brand Test To determine the fire resistance of a roofing when burning brands fall upon it, as is liable to happen to adjacent buildings when fire breaks out while a strong wind is blowing, each roofing examined at the Underwriters’ Laboratories is subjected to the burning brand test. In performing this test the burning brand is made up of 2 by 2-inch maple strips formed into a grid, the strips being approximately inches apart and held together by similar strips to which they are nailed. The brand is approximately three feet square and is ignited by placing it in a gas furnace four feet square as shown in Fig. 3. This furnace is heated by a grill of gas jets which form the bottom of the furnace chamber. The brand is supported above the jets and is exposed to the heat of the furnace for eight minutes, by which time it is all aglow and completely covered with coals. The furnace door is tilted out of the way and the glowing brand is lifted from the Page Thirteen FLAME EXPOSURE TEST EXPOSED SIDE CONDITION AFTER TEST UNEXPOSED SIDE SAMPLE SUBJECTED TO AIR CURRENTS OF 5 MILES PER HOUR SAMPLE SUBJECTED TO AIR CURRENTS OF 40 MILES PER HOUR This test is not restricted to a time limit but is continued as long as the roofing stands up under these severe conditions.

The brand is permitted to burn until entirely consumed or until the roof covering has failed by permitting the ignition of the deck boards on the under side. One operator carefully notes the time of ignition and the spread of flames on the surface of the covering, also the rate at which the brand is consumed. Another operator observes the condition of the sample on the under side. Fig. 4 shows the condition of Johns-Manville Asbestos Roofing and the unex¬ posed roof deck after this test, at a wind velocity of 5 miles per hour and 40 miles per hour. Flame Exposure Test To observe the behavior of roofing under the action of flame playing directly upon it as might occur on a building roof, a direct flame contact test is made. The apparatus used in subjecting samples of roof covering to direct flame con¬ tact is illustrated in Fig. 5. This apparatus consists of a burner with an orifice 36 inches long and ^ inch wide from which a gas flame is emitted. The flame passes over the surface of the sample directly exposing a semi-circular area about 36 inches wide by 18 to 20 inches high. The sample is set in place before the apparatus and the burner is ignited. The sample is thus exposed until the covering fails and the deck boards are ignited. One operator observes the time of ignition of the covering and the rate of spread of flame over the surface while another operator observes the under side of the deck and notes the time in which the deck boards take fire. The effects of such a test on Johns-Manville Asbestos Roofing are evidenced in Fig. 6. As a result of the extremely high fire-resistance afforded by all Johns-Manville Asbestos Roofings under these tests, the following classifications are given these roofings by the Underwriters’ Laboratories, Inc.

Lor complete description, see page 93. V a y e T h i r t y - u n e Johns-Manville Asbestone A Real Fire-Safe Asbestos Ready Roofing at a Popular Price SBESTONE is the answer to the demand for an ali-ashestos roofing— within the price range of the heavier “Rag-felt” roofings ordinarily used on the less permanent type of construction. It has been designed to give the fire protection and lasting roof service of Johns-Manville Asbestos—at a popular price. It is not a cheap roofing in the general acceptance of that expression, which seems to imply a sacrifice of quality. Asbestone is popular priced simply be¬ cause of three self-explanatory economic factors; Increased mining facilities meaning greater quantities of raw material. Quantity production with a conse¬ quent low manufacturing cost. Wide distribution and a minimum sales expense. Asbestone—What It Is CTAMPROtLOiiliih ASBESION j\,Popular Priced JonnS''Manville ASBESTOS ROOnNG STAND ROLL ON END Asbestone is exactly what the name im¬ plies—a stone roofing made from asbestos fibres and natural asphalts designed by nature for waterproofing purposes—an all¬ mineral fabric resisting alike the disinte¬ grating effects of the sun and the ravages of fire, time and weather.

H.^JKBNSr^CAHVILLEOOl NEWTORKCmr jO factoriesBzaadie^m63Iai]^ TTl Page T h i i-1 ij - t w o The asbestos felts are waterproofed with a combination of natural asphalts and the plies are united by a heavy layer of the same compound. This means a roofing of mineral fibres literally soaked in life-giving waterproofing. Economical — Fire-Safe First cost is the only cost because it never needs painting and will give years of satisfactory service without the need for or expense of repairs. Asbestone defies time and repels fire. The varying degrees of heat and cold leave it unchanged, because being all-mineral there is nothing in it to disintegrate, dry out or rot. One side of Asbestone is finished with a surfacing of crushed mineral—the other side is smooth black. It can be easily applied, each roll contains the neces¬ sary fasteners and full directions for laying. Furnished in rolls, weighing approximately 6o pounds per square of io8 square feet, including completing materials—Johns-Manville galvanized roofing nails and cement. Johns-Manville Roofing Clamps shipped when ordered. Asbestone is backed by Johns-Manville Responsibility and the liberal policy of Johns-Manville Registration, which assures the user the roofing service claimed for Johns-Manville Asbestone.

Standard Specifications Johns-Manville Asbestos Ready-to-Lay Roofing For Prepared Roofing Applied Over Wood Sheathing, Monitor Type Roofs, Slow-Burning Mill Construction with Saw-Tooth Roof, Steep Surfaces NOTE: While the following specification mentions Johns-Manville 3 -ply Flexstone, it can be used for the application of 4 -ply Flexstone, 3 -ply and 4 -ply Brooks (White Top) Asbestos Roofing and Asbestone (Asbestos) roofing, by the substitution of the name of the desired roofing through¬ out. PREPARATION OF ROOF SURFACE: Sheathing hoards shall he dry, well seasoned and of uniform thickness, laid closely—tongue- and-groove sheathing preferred. Ends of all sheathing boards shall rest on and be properly secured with at least two nails to joists or purlins. If edges of sheathing boards are curled up, they shall be drawn down and properly secured to joists or purlins, eliminating all standing nail heads and other projections. All loose knots and other flaws shall be removed, and all holes properly filled or covered. The sheathing shall be made clear of all nails, chips and other rubbish or obstructions. All drainage connections shall be set to permit free flow of water. A 3" x 3" triangular wood strip will be furnished and installed (wherever base flashing is to be used) in the angle formed by the roof and vertical surface. All to be done by owner or contractor other than roofer. Roofing materials to be applied over such surface shall be: MATERIALS: Asbestos sheet roofing ready for application, 32" wide, weighing approximately 56 lbs. per 100 sq. ft.; to be Johns-Manville 3-ply Flexstone Asbestos Prepared Roofing. Cement for laps of roofing sheets to be Johns-Manville Lap Cement. Galvanized clamps and nails to be Johns-Manville Roofing Clamps and special galvanized clamp nails. Flashing materials as specified hereinafter. Gutters and valleys treated to meet individual conditions by application of Built-up Roofing. Such materials shall be applied over wood sheathing as follows: APPLICATION OF MATERIALS: 1. Cut the roofing materials into sheets approximately 10 ft. in length. Commence at eaves or gutters and apply such sheets parallel with them, flush with edge and over edging strip of special flashing material, which shall have been previously applied. 2. Lap horizontal joints 2" and apply an intermediate layer of cold Johns-Manville Lap Cement. 3. Butt the ends of the sheets at vertical joints closely together without lapping. Lay, with black side up in all cases, the 6" wide strip of asbestos felt (furnished with all Johns-Manville Asbestos Prepared Roofing) underneath each vertical joint, extending it 3 " on each side of joint for entire width of roofing sheet. Be sure that Ipwer end of butt lap is led out on top of sheet below. Cover each strip of felt furnished for a butt end joint with cold lap cement, and imbed the butted ends of roofing sheets into the cement. Then apply clamps vertically on each side of vertical butt end joints. 4. Secure all horizontal lap joints and vertical butted joints with Johns-Manville Galvanized Roofing Clamps and special galvanized clamp nails; butt the clamps end to end approximately L2" from edges of sheets. On steep roofs, clamps may be spaced apart. 5. Extend both top sheets approximately 2" over ridge; lap one sheet over the other and nail on 9" centers. 6. Apply a capping or finishing strip of same roofing material, approximately wide, lengthwise of ridge; extend it equally on each side of ridge and thoroughly clamp its lower edges. FLASHINGS: Walls and all other elevations above roof surface shall be carried vertically at least 12", to provide for proper flashings. If such flashings are to be constructed in accordance with Johns- Manville Asbestile System, such walls and other elevations need not extend more than 8" to 10" above roof surface, unless demanded by local building authorities. Roofing material shall be carried up on vertical surface approximately 2". All flashings, except those around ventilators, standpipes, exhausts, etc., shall be composed of base flashings, of special Asbestos Flashing Material, approximately loV^" wdde, cemented and nailed to vertical surface. Such flashings shall be counterllashed with Johns-Manville Asbestile System.

Johns-Manville Corrugated Asbestos Roofing and Siding Johns-Manvillo Asbestos Roofing ( Corrugatod Form ) Monessen Foundry & Machine Co. Monessen, Fa. Johns-Manville Corrugated Asbestos^Roofing HE CONSTRUCTION of efficient yet economical buildings for commercial use has created a demand for a roofing material which, in addition to being fire-resisting, weather-resisting and time-defying, permits application directly over widely spaced purlins without sheathing. For this service, metal has met with general favor, for it possesses the necessary rigidity. But to obtain reliable service from metal roofing it must be effectively protected by some material immune to atmospheric and other corrosive influences. Otherwise, deterioration begins, rapidly progresses and in a few years your roof is eaten through and is a failure. Armored Against Rust Those who attempt to solve the roofing problem with corrugated iron, painted and galvanized, encounter rust, the ever-present destroyer of metal. Theoretically these coatings are rust proof, but the most casual investigation will demonstrate the failure of most of them. Page T h i r t y - e i g ht Galvanizing and paint are quick to flake, chip and wear away, leaving the metal base unprotected and allowing corrosion to begin its work. Johns-Manville Corrugated Asbestos Roofing cannot rust, because its metal reinforcement is armored against the admittance of the moisture and oxygen in the air by an impenetrable envelope of thoroughly impregnated asbestos felt. Its rigid metal base ot steel is locked up in an impervious casing of asbestos felts, densely saturated with a combination of natural asphalts. These asphalt- impregnated sheets on both sides ol the steel are securely and permanently ce¬ mented to it at the factory. The edges are then sealed with impregnated tape which keeps moisture, air, gases or any influence that leads to the corrosion of steel from coming in contact with this reinforcing metal. This construction insures a roofing that offers great resistance to the elements— one that cannot be affected by gases, smoke or salt air—and one that reduces cost for upkeep to a minimum.

Alfred Busselle, Architect JohnS'Manville Colorblende Asbestos Shingles Johns' Manvillo Asbostos Roofing y iSJtm0lQ Form P a (j e F o r t y - t h r e e Johns-Manvillo Asbostos Roofing ( Shinglo Form ) T he graceful, free lines of a shingle roof have been so intimately associated, from pioneer days, with the architecture of American houses that this form of roof construction can almost be called the national home roof. No roof construction offers so many varied roof effects or permits such artistic roof treat¬ ments as the shingle. To retain the attractiveness of a shingle roof and yet secure the well-known permanence and fire-protection of Asbestos, Johns-Manville has produced an Asbestos Shingle, made of asbestos fibre and Portland cement, united under great hydraulic pressure and cut to shingle shapes. These shingles are known as Johns- Manville Standard and Colorblende Asbestos Shingles and are made in various shapes and sizes and two thicknesses; A" (rough edge), in four colors—Indian Red, Autumn Brown, Natural Gray and a composite of brown shades called Conglomerate Brown; Es" (smooth edge), in Indian Red, Autumn Brown and Natural Gray only. Mixing certain combinations of these various colors in the laying produces a roof which harmonizes with the landscape like a forest hillside in Autumn—with that same indescribable blending of reds and browns and grays of frost-tinted leaves. And yet, with all its beauty of color and line, a roof that is as durable, as everlasting as stone—and equally as fireproof. To such a roof of Johns-Manville Asbestos Shingles of size No. 50, laid in Con¬ glomerate Brown alone or in combination with our other standard colors, the regis¬ tered trade name of “Colorblende” has been given. The wide variety of color effects possible in these combinations allows a “Colorblende” roof to be blended to suit the individual taste of architect or owner, and to harmonize with any architectural scheme or natural environment. Page Forty- four Where it is desired to have a certain color predominate—such as the red as shown in the plate on page 54—this is easily secured by adding a given proportion of Indian Red or Natural Clray shingles to the mixture, as desired. The color plates shown on pages 49 to 56 are a few of the color combina¬ tions suitable for “Colorblende” roofs which our Architects’ Service organization has worked out. While these reproductions may be slightly exaggerated owing to the limitations of any printed reproduction the effect of the soft blending colors of the shingles on the roof can be realized. However, these pages by no means show the range of subtle color com¬ binations possible in Johns-Manville “Colorblende” roofs and should owner or archi¬ tect desire to specify other blends our service department will be glad to offer every possible assistance. The varying shades of brown making up the composite color. Conglomerate Brown, must be considered a unit color, in treatment and in ordering and when a solid color (Indian Red or Natural Gray) is ordered for use in combination with Conglomerate Brown, it must be of size No. 50 which is the only size in which Conglomerate Brown shingles are made. The adaptability of the three solid colors of Asbestos Shingles is increased by their possibilities for contrasting color combinations and the number of free roof treatments permitted by their assortment of sizes and shapes. Thus the individuality of the building is assured, whatever its architecture. These shingles are easily laid by any roofer, slater or carpenter according to the various regular methods: American, Diagonal (or French) and Hexagonal. They may be applied to roof decks of ordinary design and so involve no expense for alterations in the framing. The cost for repairs to an Asbestos Shingle roof is virtually nothing, for it never needs paint. Extremes of temperature have no effect upon it. And the shingles are naturally so tough, accidental breakage is reduced to the minimum.

Kolb, Engineer of Design, Brooklyn, N. Y. Johns-Manville Transite Asbestos Wood Johns-ManvilloTransito Asbes to s Wood T he owner of any type of building faces the necessity of securing absolute fire protection. He faces the problem of not only making the roof, walls, floors and ceilings fireproof—but of making every part of the building proof against any blaze. Many wrongly suppose that fireproof roof, steel structure, concrete walls and fireproof doors alone constitute an all-fireproof building. Such materials as these are necessary, of course—but fire in no way limits itself to these four portions of a building. There are partitions, window casings, moldings, baseboards, boxes, recepta¬ cles, cabinets and many other places around any building which, if built of ordinary wood, offer a constant fire menace. And if metal is considered, the cost is often found to be prohibitive. In such places there is a distinct need for a fireproof asbestos lumber which possesses all the desirable features of metal without its high cost and is comparable with wood in its ease of handling and working—Johns-Manville Transite Asbestos Wood. Asbestos wood cannot burn, because nothing inflammable is used in its manu¬ facture. It is an all-rock material, made of asbestos rock fibre compressed by hydraulic pressure with binding cements into homogeneous sheets of a variety of sizes. In the rough, it presents a gray surface. Planed, it can be painted, varnished or grained where desired in remarkably true imitation of slate, marble or any hardwood. /' (( <1 e S e r e ii t // Johns-Manville Transite Asbestos Wood can be fastened with nails or screws and is designed so as not to warp, distort, weaken, chip or break in service. It is comparatively light in weight and has a tensile strength under transverse load of 3,500 lbs. per sq. in. It is widely used as a fire barrier in walls, partitions, and doors and is used in hospitals, libraries, depots and all public buildings, residences, factories, foundries, warehouses, machine shops, garages and many other types of buildings, in one or more of the following forms: Roofing Sheathing Window casings Moldings Cabinets 1 ank linings Ceiling Flooring Battens Boxes and Receptacles Wainscoting Fire doors Baseboards Fire partitions Portable houses Counter and table tops Laboratory cabinets and trim Lining and partitions for shell-loading buildings Fume ventilators Flooring around stoves Enamel oven linings Bank vault linings Dental tables Siding sheets under steel sash Fire screens Dryer rooms in rubber and automobile plants Shelves for dry kiln car¬ riers Film Storage Cabinets Gable ends of houses Lumber kiln linings Sulphur house linings Sleeping porches Office partitions Toilet room partitions Discs tor fan bases Railway signal wire box- ing _ Barriers of all sorts for fire protection from electri¬ cal apparatus Johns-Manville Transite Asbestos Wood is examined and approved by the Underwriters’ Laboratories, Inc., under the direction of the National Board of Fire Underwriters.

Page S e V e n t, g - f 0 u r Johns'Manvillo Asphalt Mastic Floor J OHNS-MANVILLE Mastic owes its rugged resistance to the “know how” of the experienced engineers who determine the consistency of your floor before the materials leave the factory. It owes its durability to the way these materials are put together and laid by expert workmen, to withstand the hardest knocks or to meet the lightest service conditions. It’s the combination of the best materials and the brains and experience of our experts that makes Johns-Manville Mastic supreme. This floor is in the nature of an asphaltic concrete and consists of a binder or cement made up of a combination of natural asphalts and a well-graded mineral aggregate of torpedo gravel, crushed stone and sand with particles ranging in size from those passing a ^-inch mesh screen down to those which pass a 200-mesh screen. Success with this type of floor demands a careful grading of the aggregate particles and their intimate mixture with the cementing materials in a manner that will insure the densest possible product in which even the finest particles are thoroughly coated with the asphaltic cement and which it is impossible to obtain in a field mixture. Therefore, to insure this essential result in Johns-Manville Mastic Flooring, the aggregates passing an 80-screen are combined with the asphalt by heat and mechanical agitation for a period of six to seven hours at our factory rather than at the site of the work. The mass is then molded into blocks of convenient size for shipment. These blocks are broken up on the work and reheated to a temperature of 450 deg. F. and mixed with the coarser aggregate, using a pure asphaltic flux to help break down the blocks in the kettle and govern the consistency of the floor. The resulting softened and plastic mass is transported to the work in oak buckets and is then laid down in one or two courses depending upon the required thickness and given a comparatively smooth finish by rubbing with wood floats. By reason of its remarkable ductility, toughness, strength and enduring qualities, Johns-Manville Mastic Flooring is peculiarly adapted for the work it is called upon to perform in floor use under various conditions. It provides a surface that is waterproof and at the same time practically wear-proof. It is also highly resistant to the effect of acids, alkali, and brine. These characteristics should appeal to architects and owners of breweries, distilleries, canning factories, packing-houses, ice-cream factories, creameries, cold storage plants, warehouses, freight houses, railroad shops, machine shops, school houses, institutions, platforms, loading docks, plating establishments, battery houses, chemical laboratories, pickling-tanks and tank rooms in smelters. Another point of vital importance in establishments where light or accurate machinery is in operation, or where merchandise is stored, is that Johns-Manville Mastic Floors do not originate or hold dust. Page Seventy-five This flooring is unequaled for factory and warehouse use, even under the heaviest trucking conditions, and on account of its noiseless character is a boon to plants where there is considerable trucking. It also has a peculiar holding quality which has a tendency to prevent slipping. Johns-Manville Mastic can be laid in any consistency between extreme hard¬ ness and softness and while always dense, possesses a certain amount of resiliency. It does not cause foot-soreness and fatigue, like concrete and other non-yielding floor surfaces and where employees of machine shops, factories and other industries are compelled to stand while at work, it adds greatly to their comfort and efficiency. Furthermore, being damp-proof, it is a protection against rheumatism and other ailments common to damp conditions. This flooring is easily laid and easily repaired if changes in the floor surface are made necessary at any time. It adds very little to the dead load, as the standard thickness of inches weighs only i8 lbs. to the square foot, in place. This thickness is sufficient for ordinary trucking requirements, but can be varied to meet conditions, ranging from i inch for foot traffic, where the requirements are very light, to 2 inches in thickness for loading docks where the requirements are correspondingly severe. It can be laid over any foundation which is firm and stable and can be applied over wood, brick, concrete or tile already in place. If these surfaces are badly worn, it is preferable to level up the inequalities by the use of cement grout. The finished surface is monolithic, without construction joints or cracks to collect or hold dirt or moisture. The installation of this floor does not necessarily occasion any delay in the operation of a plant. Johns-Manville Mastic Matrix This is the asphaltic cement or binder incorporated in the mastic block as manufactured at the factory to hold the fine mineral aggregate together. By our careful manipulation and close supervision, absolute uniformity of the consistency of the material is assured. Johns-Manville Standard Asphalt Mastic This product is a finely graded mineral aggregate bonded together by an asphaltic cement or binder. This mineral aggregate will pass through screens ranging from 8o to 200-mesh in fineness. The asphaltic cement or binder is heated to a temperature that will allow the fine mineral aggregate to be thoroughly incorporated by constant agitation in a Page Seventy- six mechanical mixer for a sufficient length of time to assure the thorough coating of the very finest of the mineral aggregate, which result can be accomplished in no other satisfactory manner. After the mixing process has attained the desired results, the mass is drawn from the mixer and molded into octagonal-shaped blocks and our brand J-M imprinted in each block. JohnS’Manville Asphalt Fluxes These materials are manufactured in various consistencies ranging from extreme hardness to softness and have the same general make-up as mastic matrix. They are added to the Johns-Manville Mastic in proper proportions to produce a floor of the desired texture, which may be of a hardness to withstand extreme conditions of wear and tear or of a softness to withstand shock from temperature changes without checking or cracking. The material is shipped in sheet iron drums containing approximately 450 lbs. each. Mineral Aggregates Mineral aggregate can be in the shape of washed torpedo gravel, crushed limestone or granite, trap rock or any other hard, flinty mineral substance which may be peculiar to the locality, mixed with a small percentage of torpedo sand which is entirely free from loam or dirt. Briefly, a clean, properly graded mineral is absolutely necessary to meet requirements. It is added to the Mastic and Flux after the same have been thoroughly broken down by heat in suitable boilers and the temperature of the Mastic brought to 450 deg. F. This mineral aggregate is procured locally wherever possible. Johns-Manville Acid-Proof Asphalt Mastic Where acid conditions prevail and trouble is being experienced on account of tile, concrete or wood floors proving unsatisfactory, the trouble can be overcome by the use of Johns-Manville Acid-Resisting Asphalt Mastic Floors. This mastic is manufactured in the same careful manner as our Standard Johns-Manville Asphalt Mastic, the asphalt cement or binder being the same in both products. However, in the manufacture of our Acid-Resisting Asphalt Mastic we make use of a mineral aggregate which is immune to the action of commercial acids. Acid-proof Mastic is also shipped in octagonal-shaped blocks. The mineral aggregate which is further added to the Johns-Manville Acid- Proof Asphalt Mastic must be immune to the acids encountered. The grading of this mineral aggregate should be the same as that used in our Standard Asphalt Mastic. P 0 (j e S e V e n t y - s e v e n Johns-Manvillo Asphalt Mastic Rooiing as a Firo Retaidant M odern building practice demands that as many of the materials as possible be fire-resisting to a greater or less degree. The following facts on Johns- Manville Mastic Flooring will answer your most searching questions as to its ability to retard fire. A few years ago the National Board of Fire Underwriters completed exhaustive tests to determine the fire-retardant qualities of Johns-Manville Asphalt Mastic Flooring. The following excerpts from their report (dated August 21, 1917) substantiate our claims for Mastic Flooring as a fire-retardant and are vitally important to every one interested in flooring for industrial and mercantile plants, public and private institutions, shops, breweries, packing-houses, laundries, railway buildings and all floors where the service is particularly severe. Under the heading of “Fire-Resisting Properties,” the report of the Under¬ writers’ Faboratories, Inc., says of Mastic Flooring:— “The top flooring is not readily flammable and does not carry or communicate fire to any material extent. It disintegrates slowly under heat, affords very considerable heat insulation to the floor structure and the progressive disintegration does not materially reduce the insulation afforded. “By comparing a sample of the Mastic top flooring with a sample of the maple flooring, it will be seen that the maple flooring was readily flammable and carried and communicated fire to a material degree, giving off flame in considerable volume and more or less smoke. By referring to the logs of tests it will be seen that flames developed on the maple sample in I minute and 45 seconds after which it burned readily and spread rapidly, reaching the unexposed end of the sample in 20 minutes. “In th e case of the Mastic sample, flame developed in 5 minutes and 50 seconds and spread slowly, giving off short, intermittent flames. At the end of the test (i hour and 10 minutes), it had only reached to a point 6 feet from the exposed end of the sample. At the end of tbe test, after the exposing flames had been extinguished and the gases of combustion given off from tbe wood at the edges of the sample had been quenched wdth water, the surface of the sample ceased to burn.” In addition to their findings concerning the fire-resisting qualities of Mastic the Underwriters’ Faboratories, Inc., also incorporated in their report much inter¬ esting data on the design, construction, practicability, durability, etc., of Mastic Flooring. Quotations follow:—• P a ij e Seventy-eight “DESIGN AND CONSTRUCTION “The design and construction of the top flooring are suitable for the purposes intended. The materials are suitable for the purpose, forming a homogeneous mass which can be readily installed under ordinary service conditions.” “PRACTICABILITY “It is practical to prepare the materials as furnished to the job and to apply them in the manner advocated. The flooring can be easily repaired or maintained if repairs and main¬ tenance are required.” “DURABILITY “All floorings examined in the field were subject to hard usage and in no case was there any apparent deterioration from the effects of wear. “In none of the installations examined was there any evidence of deterioration in the top flooring due to expansion, contraction or settlement of the building. In only one of the in¬ stallations examined was the top flooring exposed to the elements, but this installation ap¬ peared to be in good condition. “While the investigation did not give positive evidence to the effect that the top floor has no deteriorating influence on the floor structure, a knowledge of the materials used indicates that if anything the top flooring should have a preservative effect. “Although the floorings were carefully examined for cracks which would ordinarily indicate failure of the surfacing to conform to the expansion and contraction of the main flooring in which it rests, no cracks were discovered, indicating that the surfacing is not open to criticism in this particular. In only one of the installations examined was the flooring exposed to the elements, but no criticism developed in the case of this installation.” “ACCIDENT HAZARD “This flooring material, by offering a relatively high resistance to slipping, should reduce the accident hazard due to this cause. “The examination of the material indicated a structure presenting a suitable anti-slip sur¬ face both when new and worn. “The friction tests brought out results comparing favorably with results of test on anti¬ slip surfaces which have proven to be effective in reducing accidents due to slipping. “Examination made in the field, showed no marked difference in the resistance to slipping after being subject to actual service conditions.” Page S e r e n t y - n i n e Standard Specifications Johns-Manville Asphalt Mastic Floor Specification for Johns-Manville Asphalt Mastic Floor 1 -Inch Thickness After the concrete base has been placed and pitched, if necessary, to the proper grade for drainage, it shall be given a finished and floated surface free from all sharp projections or offsets of any character except those shown on the plans.

The asphalt mastic shall be laid in one layer of one and one-quarter inch thickness, spread with wood floats and sufficient pressure applied to eliminate all voids and blow-holes; making a homogeneous mass throughout. When the joints are made, the hot mastic shall be laid over the cold edge of the joint already on the floor, and allowed to remain until the same is thoroughly heated. The surplus material shall then be cut ofF and the joints made compact and tight by rubbing with wood floats. The top shall be given a sand or cement finish in the following manner: In case of a sand finish, the top surface, while hot, shall be sprinkled and rubbed with fine, dry, sharp sand, which shall be thoroughly rubbed into the surface of the mastic, and the surplus sand left on the floor until the same is put in use. In case of a cement finish, the top surface shall first be sprinkled and rubbed with fine, sharp sand, which shall then be swept off while the material is still warm. The surface shall then be dusted with Portland Cement and the same thoroughly rubbed in. Specification for Johns-Manville Asphalt Mastic Floor 13^-Inch Thickness After the concrete base has been placed and pitched, if necessary, to the proper grade for drainage, it shall be given a finished and floated surface free from all sharp projections or offsets of any character except those on the plans. The concrete shall then be allowed to set and dry out. When necessary, on account of the condition of the foundation or base on which the mastic floor is to be laid, one-ply of rosin-sized building paper shall be spread over the floor surface and lapped three inches. (The use of building paper may be called for to prevent moisture or grease working up into the mastic from the concrete or wood base, or may be necessary in order to provide independent movement in the mastic floor on account of movement in the base.) 1 he Mastic Blocks shall be delivered on the ground plainly marked with the name of the brand and broken up before being placed in the mastic kettles. There shall then be added the proper percentage of asphalt flux and both allowed to cook until the mastic blocks are entirely melted. The mineral aggregate in the shape of washed torpedo gravel, torpedo sand, crushed limestone or granite, in the proper percentage to give the required consistency or hardness, shall then be added and thorougbly mixed into the mass by the use of iron stirring rods and the temperature of the mix brought to 4:50 degrees Fahrenheit. The material shall be constantly stirred to prevent burning and then removed from the kettles in oak buckets or all iron wheelbarrows and taken to the work as required. The mineral aggregate must be thoroughly dry before being introduced into the mastic and shall be a clean, properly graded material, satisfactory to the engineer or architect, and of such size and grading as will meet the peculiar service conditions. 1 he asphalt mastic shall be laid in two courses, each layer being inch in thickness, making a total thickness of 13^ inches. It shall be spread with wood floats in such a manner as to avoid bringing the joints in the two courses of mastic directly over each other and these joints shall be lapped at least 12 inches. Sufficient pressure shall be applied at all times to eliminate all voids and blow-holes, making a homogeneous mass throughout. When the joints are made, the hot mastic shall be laid over the cold edge of the joint already on the floor and allowed to remain until the same is thoroughly heated. The surplus material shall then be cut off and the joints made compact and tight by rubbing with wood floats. 1 he top shall be given a sand or cement finish in the following manner: In case of a sand finish, the top surface, while hot, shall be sprinkled and rubbed with fine, dry, sharp sand, which shall be thoroughly rubbed into the surface of the mastic and the surplus sand left on the floor until the same is put in use. In case of a cement finish, the top surface shall first be sprinkled and rubbed with fine, sharp sand, which shall then be swept off while the material is still warm. The surface shall then be dusted with Portland Cement and the same thoroughly rubbed in.

P (I <1 e E i (I k t n - t w 0 Waterproofing — the Largest Job of Waterproofing Ever Executed Under One Contract Page E i g h t y-t h r e e Johns-Manvillo Watorproofmg Why It Makes Good T he quality of a product depends not only on the experience, skill and equip¬ ment of the manufacturer, but also on the care taken in the choice of the materials from which it is made. One reason why Johns-Manville Waterproofing makes good is because the various products are selected and manufactured under such high and rigorous standards. Another factor, equally important, is that the Johns-Manville Method of Waterproofing is the result of years of actual service experience and laboratory research, plus proper design and honest manufacture of the very materials which nature itself intended for waterproofing purposes. Therefore, Johns-Manville Waterproofing is the best that human brains and hands can produce. Johns-Manville service is your safeguard. We are specialists in this field and would be glad to have you take advantage of our experience from the specification and design right through to the application of the materials. Waterproofing—What It Is Waterproofing is a broad term often misapplied and misunderstood. In reality waterproofing should only be thought of when moisture and seepage is present, i. e., where there is actual water pressure arising from surface seepage or hydrostatic pressure. Every other case of waterproofing properly comes under the head of DAMP-PROOFING. Damp-proofing—What It Is Damp-proofing is protection against moisture where no actual water pressure is encountered. It is simply the prevention of condensation or dampness appearing on the surface of walls or floors. Two Methods of Waterproofing—Integral and Membrane It is an accepted fact among engineers and architects that there are but two methods of waterproofing. But it has been proven that only one of them is capable of giving positive results. The Integral Method—Why It Fails This method provides for the incorporation of a powder or paste into the con¬ crete during its construction. It is mixed with the cement, becomes part of the /•’ d ji J'] i (j h I 1/ - f ') II I' mass and is supposed to add to the density of the concrete to such an extent as to prevent the seepage of water. The incorporated material from its very nature, tends to destroy the integrity of the concrete and for that reason, if no other, cannot be successful. Experiments have proven this method is non-uniform and totally unreliable, even under laboratory conditions. It is an absolute failure when pin or hair cracks or large openings develop in the concrete, due entirely to expansion and contraction or unequal settlement in the structure. The Membrane Method—Why It Succeeds This method provides for the application of a protected bituminous skin or coat over the surface to be waterproofed. The membranous covering of water¬ proofing cement, reinforced with fabric or felt or both, is strong and flexible and has the necessary characteristics to resist water pressure and enough give to bridge over hair cracks in the concrete due to temperature changes. The membrane is built up in as many plies of reinforcing material as are necessary to meet the conditions. Johns-Manville Membrane Waterproofing Johns-Manville Membrane Waterproofing is the result of years of experience in the successful waterproofing of every conceivable type of construction. It has been proven by actual experience to be the most economical, not in the first but in the last cost and the most satisfactory, because it is waterproof—not approximately, but absolutely waterproof. Why No Specifications A re Possible Unlike every other product used in building construction, a dehnite specifica¬ tion for Johns-Manville Waterproofing cannot be written to meet efficiently every character of waterproofing. Each construction presents a different problem, involving local conditions and individual requirements which must be viewed from every angle. Then and only then will we be able to give a definite specification. Materials Used in Johns-Manville Waterproofing Johns-Manville Concrete Primer This is the first coating applied to the concrete, brick or stone surfaces which are to be waterproofed. It penetrates the surface to such an extent as to form an anchorage for the subsequent waterproofing. It also acts as a cleanser for the surface, preparing it for the asphaltic coatings to follow. The covering capacity of this material should run about too square feet to the gallon on comparatively smooth surfaces. Page Pi u h I - f i v e Johns-Manville Asphalt Waterproofing Cement This is applied while hot over the Primer and is used to cement the various fabrics together into one composite sheet. Owing to great care exercised during the process of manufacture, this bituminous material is absolutely uniform in character. It is 99.5 per cent, pure and contains no matter that will disintegrate or decay. Proof against the action of cold acid, alkali, brine and water, very slightly affected by a wide range of temperatures, between melting and brittle points. To apply this Waterproofing Cement it is heated to 450 deg. F. and mopped on while hot. One ton of this material should cover 3000 square feet of surface yi" thick. Johns-Manville Waterproofing Asbestos Felt Used as a reinforcement and to give substantiability and strength to the mem¬ brane. Cemented together and bonded to the concrete by the waterproofing cement. It is made of pure asbestos (rock fibre), thoroughly impregnated with pure asphalt. This is the only all-mineral felt made, therefore, the only material of its kind that is proof against water, cold acid, mold and decay, for all time. Virtually a pliable bituminized stone sheet. Johns-Manville Asphalt Saturated Fabric Used not only as a reinforcement for the membrane but to give added tensile strength. This is an especially strong cotton or hemp fabric used in connection with Waterproofing Asbestos Felt in as many plies as are required to meet the conditions. Being an open-mesh material, the waterproofing cement, which is mopped on hot, thoroughly saturates, cements and bonds together the several plies of the reinforcement. Johns-Manville Asbestos Duck This is applied in the same manner as the other materials which make up the membrane, but only where unusual strength is desired. It is a composite sheet of asbestos felt and cotton duck thoroughly saturated with waterproofing cement. This material is largely used when working under wall footings or column bases. Johns-Manville Self-Healing Waterproofing Cement This is an asphaltic compound which carries a very low congealing point and a melting point of 125 deg. F., although we can furnish it with a melting point of 90 deg. F. when a softer material is desired. The use of this product is naturally limited for waterproofing purposes on account of its tendency to move readily under comparatively high temperatures and also its extremely viscous nature. For brine decks in packing-house hog-coolers and for waterproofing work between Page Eighty-six wooden floors, this material is ideal. We have also found that on account of its adhesiveness at low temperatures it makes an excellent expansion-joint filler and we are using it largely for that purpose, especially on mastic roof work. It is shipped in wooden barrels weighing approximately 500 pounds and half barrels weighing approximately 250 pounds. Johns-Manville Pickling Tank Cement This is an asphaltic compound evolved principally for use in lining the inside of wood or concrete tanks where an acid-proof coating is a necessity. It is mopped on the surface in a heated condition and carries a melting point of 212 deg. F., although a softer material can be furnished if desired with a melting point of 175 deg. F. In lining wooden tanks it is sometimes used to coat the tongue and grooves of the boards when the tank is being built, the boards being drawn tightly together and held in place permanently by the use of wooden dowels. After the tank is erected the inside is primed and given from two to four coats of the Pickling Tank Cement. It is immune to all the cold commercial acids, including hydrofluoric. It is shipped in iron drums weighing approximately 450 pounds. Johns-Manville Pipe Dip This is an asphaltic compound used for coating iron pipes. It is first melted down in a large iron tank and the pipes heated to the same temperature as the Pipe Dip, after which the pipes are dipped in the coating and then drawn out and the material allowed to set and harden. It is used generally by pipe manufacturers for coating pipes that are to be placed under ground and is an excellent protection against rust and corrosion, at the same time providing high insulation against electrolysis from stray electric currents. Johns-Manville Expansion Joint Filler An asphaltic compound of great tenacity used for filling expansion joints. Shipped in iron drums of approximately 450 pounds. It is poured into place. Immune to the action of street acids. Johns-Manville Bituminous Putty This material is composed of an asphaltic compound and asbestos fibre, used as a filler to prevent the infiltration of water in recesses where a permanent seal is hard to maintain with the waterproof membrane. It forms an elastic bond but little affected by temperature change and vibration. Largely used in connection with certain types of bridge waterproofing where the waterproof membrane is sealed to the sides of the girders. Page Eightg-seven Johns-Manville Asbestos Fibrous Enamel Johns-Manville Asbestos Fibrous Enamel is a combination of the two mater¬ ials most impervious to atmospheric conditions—-asbestos and natural asphalt. As a protective coating on any material which deteriorates under weather or climatic conditions, it is by its very nature unequalled. Recommended for pre¬ serving felt and metal roofings, gutters and flashings and for the prevention of rust and corrosion of cornices, skylights, chimneys, fire-escapes, girders, lamp-posts, trolley and telegraph poles, agricultural implements, contractor’s equipment, in fact, any kind of exterior or interior iron or steel work. The natural elastic qualities of the asphalt binder, combined with asbestos fibre, allow it to accommodate itself to the expansion and contraction stresses of the surface on which it is applied, without peeling or cracking, and hence main¬ tain its protection. It is more economical than ordinary linseed oil paints and much more efficient. Johns-Manville Damp-proofing—Materials Used In the large majority of cases the application of cold surface coatings will effectively damp-proof a structure. There are, however, special cases of damp¬ proofing which require the membrane method of waterproofing. We firmly be¬ lieve and successful installations prove, that Johns-Manville Damp-proofing is the most efficient system to keep out dampness and to prevent discoloration due to the absorption of moisture. Johns-Manville Liquid Waterproofing Coating This is used in connection with Johns-Manville Concrete Primer and is ap¬ plied cold, in one or two coats for damp-proofing only. It is used for wall work or for other surfaces not liable to injury from abrasion and where there is no hydro¬ static pressure. It will withstand seepage of surface water and prevent the dis¬ coloration or staining of the outside face of concrete walls. It has a covering capacity over smooth surfaces of about 200 square feet to the gallon when used over the Primer. Johns-Manville Cut Stone Backing This is used for coating the sides and back of cut stone to prevent discoloration and dampness of inside of interior walls. It should cover approximately 60 square feet per gallon over rough surfaces. Johns-Manville Aquadam 'Phis is applied cold over brick, stone or tile and concrete surfaces, where it is required to damp-proof the walls. In tile partitions, it prevents dampness from driving the saltpeter out of the tile, through the plaster and discoloring the decora¬ tions. After it is applied, furring and lathing is generally unnecessary. It also eliminates the air space caused by furring and lathing, thus doing away with a dangerous passage for flames in case of fire. It is applied in one or two coats, depending upon the porosity of the surface. It has a covering capacity of about 80 square feet per gallon. P a (j e Eighty -eight specification for Johns-Manville Aqtiadam Damp-proofing Unlike Johns-Manville Waterproofing, we are able to give a definite specification of Johns- Manville Damp-proofing. Ihis is possible because with damp-proofing the conditions are so nearly the same in the large majority of installations. A specification of the application of Johns-Manville Aquadam follows:— EXTERIOR Where so specified, the exterior surfaces of foundation walls shall he damp-proofed below grade with H. W. Johns-Manville Company’s Aquadam. I'he Johns-Manville Aquadam must be well stirred before using. If the surface over which the Johns-Manville Aquadam is to be applied is wet, damp or liable to contain frost, it must be allowed to dry before tbe damp-proofing is applied. If the surface is of a porous nature, it should be given two coats ot Aquadam, the first coat being allowed to dry before the second is applied. INTERIOR Where so specified, the interior surfaces of exterior walls shall be damp-proofetl with Johns-Manville Aquadam. I he Johns-Manville Aquadam must be well stirred before using. It the surface over which the Johns-Manville Aquadam is to be applied is wet, damp or liable to contain frost, it must be allowed to dry before the damp-proofing is applied. If the surface is of a very porous nature, it should be given two coats of Aquadam, the first coat being allowed to dry before the second is applied. The final coat of damp-proofing must he allowed to take an initial set of twenty-four hours before being plastered over.

Dining Room, Harvard Club, Boston, Mass. Parker, Thomas & Rice, Boston, Mass., Architects ./ohns-Manville Acoustical Correction T he Acoustical Department of the Johiis-Manville Comjtany is maintained for the jnirj)ose of conferring with architects and ow ners in the design and con¬ struction of new buildings to insure good acoustical conditions as well as to correct poor acoustics in structures already built. Through its System of Acoustical Correction the Johns-Manville Company is j)rej)ared to |m(xluce good hearing (|ualities in auditoriums of churches, theatres, court-rooms and other j)ublic huild- ings; also to reduce to a minimum the fatigue and loss of efficiency due to confusion and noise in offices, banks and rooms of similar character, resulting from the unavoidable concentration of employes and noisy, mechanical office appliances. In broad terms, good acoustics requires that there shall be no confusion or blurring of sjieech or music due to overlapping or interference of tones and syl¬ lables and that everything shall be done to bring about that clarity of tones which P a (j c y i n e t y - o n e is consistent with the maintenance of sufficient loudness and i)roi)er balance. The acoustical conditions of any room are affected partly by size and shape, and partly by the character of interior surfaces and furnishings, as well as by tlie distribution and size of the audience or occupants. A certain amount of absorption is necessary in every auditorium. In some cases furniture and the clothing of persons provide all that is needed in this respect, but more often artificial treatment is required and these factors must be carefully studied in every case. The nature of the treatment, its amount and location, is a matter for expert determination. The problems involved are highly technical and for their satisfactory solution the trained knowledge of specialists is indis¬ pensable. Through the Johns-Manville Company, the services of competent acoustical engineers are available to architects and others who have acoustical difficulties to be overcome. The methods used are based on the scientific researches of the late Professor W. C. Sabine of Harvard University and the Johns-Manville Com¬ pany has developed special materials and methods of apj)licati(jn for producing the necessary correction. The Johns-Manville engineering experts are prepared to examine plans and specifications at any time, without fee, and to recommend suitable treatment where it may be necessary.
