There are hundreds of taxpayers and building superintendents in this city who are actually giving- money to the city and ■are getting no return for it. They do not know that they are doing it. but they are just the same. Their water meters are running fast and when the inspector comes around and saj's the hill is eo much, it is paid. But the Water Super¬ vision Company. 3 Park Kow, makes a specialty of looking out for the owner's pocketbook. About ten hundred millions of gallons of city water are saved from waste each year all of which would otherwise have flowed away but which would have been,, paid for by the taxpayer. Even in the largest plants where a staff of engineers are employed, the expert services of this company have resulted In eliminating un- thought of and unlocked for waste. One Way to Avoid Roof Repair Worries. The average building manager, owner or architect finds that the roof problem, while a seldom recurring one, is, none the less, annoying, to say the least. It means that prompt action >must be taken or serious damage might occur. This is especially true in summer, when a sud¬ den shower may do more damage through a leaky roof than a whole season of snow. The Southern Roofing & Repair Com¬ pany. 147 East 2Sd st, makes a specialty of relieving owners and others of this worry by its system of looking after roofs fey the year. It has many years of prac¬ tical experience in the repair of all kinds of roofs, and Mr. William B. Shryock, an expert in this line, gives each joh his per¬ sonal attention. The roofs of some of the ■most important buildings in New Tork are under his care. Spunky Concern Wins Ti-ade Pi-aise. The average man admires a fellow that when once knocked down is quick to get on his feet again and show that he is made of the right kind of stuff. That is the case with the Janusch Manufacturing Co., makers of hrass and iron goods with an office and factory at 496 and 49S East 134th st. With the ruins of their factory still smoking and with the fire engines still on the scene, their customers received the following postal card the next morning, March 8: "Our plant was completely destroyed by fire last night. ' "We shall resume as quickly as adjust¬ ment can be made, and all orders you have placed with us wil! be fllled at an early moment. "We wish to thank you for the many fa¬ vors tendered us in the past and hope we will retain the confidence you have re¬ posed in us for over 37 years. "The same energy and perseverance will rebuild what it has taken only hours to destroy. "Trusting you will exercise as much len¬ iency as possible and oblige, The Janusch Manufacturing Co. (Telephone. Melrose 1322.)" The company's showrooni is at 18 East 22d st, and It also has a brancji office, in San Prancisco. Perro-I/ithic Plates. A catalogue from the Berger Manufac¬ turing Company (llth av and 22d st. N. T. C), describes the patented Ferro-Lithic plates for reinforced concrete construc¬ tion. One of the illustrations shows the application of the system to a residence at Tuxedo Park, N. T., from plans hy the Taft-Howcll Co., of Cornwall, N. T., ar¬ chitects and contractors. , Ferro-Lithic steel plates are plates whose cross-section shows a continued series of alternate dovetails. Because of this shape it is possible to concrete and plaster directly upon the steel plate. The constant demand for light weight and consequent low^ dead load in concrete construction was a reason for the Ferro- Lithic Interlocking System of Concrete Reinforcement. Ferro-Lithic steel plates were originally designed for combined centering and rein¬ forcing of concrete to meet the demand for a permanent, fireproof concrete roof. FBRRO-LITHIC PLATE READY TO LAY. The application of these plates has been extended into other fields and they are now extensively used for centering and reinforcing of concrete slabs for flat and arched floors, for sidings of buildings, lin¬ ing of coal bunkers, and sidewalk con¬ struction. They are applicable to either reinforced concrete frames" or structural steel frames, the better application being to the structural steel framing. A Sti'eet Directory. A formula for flnding the nearest cross street to a given address on an avenue, Manhattan Island: Cancel the fast figure of the given house number, divide the remainder by 2 and add the number specified in the following key: Avenue A....... 3..........Avenue 4----18 Avenue B....... 3.......... 5----17 Avenue C....... 3..........

First cancel the last figure. The remainder is S6. Divide by 2, giving 43. Add key number 10. and you will flnd that 863 3d av is near 53d st. Store and Building Lighting That Saves Money. The lighting problem always was a most perplexing one to the manager, owner or agent, as well as tenant, but new ideas and new sj-Ktems are rapidly solving this difficulty. Within the comparatively re¬ cent past architects have had their at¬ tention called to the system of the United Tungsten Lamp Company (Marbridge Building, 132S Broadway), of which Mr. W. P. Crarey is president. This system is admirably. adapted for use in stores, factories, garages, churches-, hall's, cluhs. railroad, stations, .and private and public biiiid'ings .o£ .all. kinds. .Where a 176-cp. arc. lamp costs G% cents an hour a Tung¬ sten lamp of the United system will give 200 cp. at a cost of 2Y2 cents an hour. The U. T. L. Company's claim is that with the proper installation of the Tungsten lamp an actual saving of 50 per cent, will be accomplished, and "if in any way, this should not be so, there will absolutely be no charge for the equipment." Here are a few instances of installation that have made good, according to the company. All the Regal Shoe stores are being equipped w^ith the United Tungsten Lamp Co.'s system of illumination, by which the saving to this shoe company will be the difference between a yearly expense of $1T,000 and $7,000. B. Sadow¬ sky, at Broadway and llth st, has just in¬ stalled the largest equipment ever execu¬ ted in this city. He has put in 400 250- Watt Tungsten lamps, and he says that he is receiving more than 25 per cent, more light at 50 per cent, less cost than with the other kind of electric illumination. Still another installation is that the fac¬ tory of Palmer & Singer,, automobile man¬ ufacturers, Astoria, where 4i5G 40-Watt lamps were recently installed. The United Tungsten Lamp Company employs only experts, and each installation is scientifi¬ cally studied before installation is begun. It maintains a staff of proficient engi¬ neers, and is capable of taking up and solving any lighting problem. Mineral Oil and Cement. A pamphlet has been issued by the Vulcanite Portland Cement Company upon the subject of Concrete and Min¬ eral Oil used in combination, written by Albert Moyer, Assoc. Am. S. C. E. By mixing semi-asphaltic base oils with ce¬ ment concrete it is hoped to obtain in the combination the desirable qualites of both for use as a road material. The mixing of oil (mineral) with con¬ crete is very simple, says the author of the treatise. The oil, alkalies and wa¬ ter will form an emulsion becoming thor¬ oughly incorporated In the concrete. If the concrete is to be mixed by hand. proceed as usual, and, after the water has been added, the resulting mass turned and raked, add non-volatile mineral oil in proportion of 10 to 15 per cent, of oil to the weight of fhe cement. Turn the concrete with shovels two or three times, raking while turning; the oil will quickly emulsify and become thoroughly mixed in the concrete. If machine mixing is employed, use a batch mixer, turning a sufficient num¬ ber of times to thoroughly mix the ce¬ ment, sand, crushed stone or gravel and water. Then add 10 to 15 per cent, of non-voIatlle mineral oil. Turn again the same numher of times as it requires to mix the concrete. The oil will quickly emulsify and become thoroughly Incor¬ porated In the concrete. Oils added to concrete in proportions of from 5 to 15 per cent, will slightly delay the Initial and flnal set. Increasing the proportions of oil will further retard both the initial and flnal set and hardening, from experiments so far made, it would' seem that the retarding of hardening will not be sufflcient to cause the work to be uneconomical. The tensile strength will necessarily be reduced, and with the Increasing percent¬ ages of oil toughness will be slightly di¬ minished, but not In proxwrtlon to the Increase In the percentage of oil used. Electi'ic Power in Constrnction Work. The Thompson-Starrett Company, gen¬ eral contractor for the new Municipal Building, has signed a contract for 400 horsepower in motors, 200 incandescent iamps and 100 arc lamps. Electricity will be used exclusively for light and power In the erection of the superstructure.
