This gives you some idea as to the character of work and the quantity of work that the Department of Labor, now the Industrial Commission, has done. Total orders issued up to March 1st, 3,290 and compliances secured, 1,569, that is, about twice the number of orders issued as compliances secured, giving about 1,500 or 1,600 compliances still to be secured. I have not had time to segregate these orders to determine whether they were for glare or for improper distribution, etc. From what I can remember, most of them were for the elimination of glare or minimizing of glare. Many other orders have since been secured, no doubt, but I have only given statistics up to the 1st of March. These orders go out, and the parties upon whom they are served are given a definite time in which to comply with the law. Manufacturers may ask for an extension of time. In that case the order still is pending. In the case of all orders that are pending, compliance will be insisted upon, and if the ordinary method does not secure it the Court will be resorted to. We have a capable legal bureau and these things are threshed out in Court if necessary. W. P. Hurley: It seems to me that if the codes in themselves are in advance of the popular education, it is the work of the promotion of these codes that needs to be taken in hand, in order to, make them of the greatest efficiency. We may get ourselves into the position of the states of Wisconsin and Massachusetts, with their insurance laws, where they passed useful and effective laws, providing for state insurance, but they fell flat because the popular education was not sufficiently advanced on the subject for the people to make use of them. One of the most interesting points, that has not been touche. Bookseller Inventory # APC9781130204810

Not illustrated. 1906 Excerpt: .on the cashier s eyes, while the boot-black stand requires a special lamp. It is very desirable to place a lamp so that men can read with comfort while having their shoes shined. Mr. Allen.--I have made provision for one 60-watt tungsten lamp near the cashier s desk. At the boot-black stand the illumination averages at least 2.5 foot-candles, and considering the reflection from the walls, it would seem that there is no need for an extra lamp at this place. In regard to the use of four large main lighting units instead of a larger number of smaller units, it should be noted that when there are many lighting sources the retina of the eye contracts and hence the smaller the number of units the better the real illuminating efficiency. The particular units chosen give a good light distribution for illuminating the floor. The absorption is somewhat greater than with opal reflectors, but the real illuminating efficiency is improved by the reduction in intrinsic brilliancy. By using clear lamps the loss of useful life due to frosting has been avoided. The fixtures are so designed that a current of cool air drawn in at the bottom of the shades is brought in contact with the lamps and passes out through an opening in the fixture casing. Tests have shown that the temperature rise is well within safe limits. Mr. W. H. Blood, Jr.--The form of window lighting proposed by Mr. Daggett does not appeal to me. Fully 30 per cent of the light is lost by the use of ground glass. Equally as good effects, and in many ways a superior lighting, can be obtained by means of green shades placed close to the window so that no light will be thrown in the eyes of people on the street. In this way intense light would be obtained on the merchandise in the window. Mr. F. E. Smith.--I ask Mr. Bookseller Inventory # APC9781130451733

At the last convention of the American Gas Association data was presented7 showing that approximately 20 per cent of the gas sold by companies in this country is used for lighting purposes. Manufacture.--A manufactured gas has been reported8 in England which with a calorific value of 350 B. t. u. is claimed to give the ordinary consumer the same value as he can get from a 500 B. t. u. straight coal gas. It is used in burners without Bunsen tubes and is supposed to obtain aeration for combustion purposes from the air surrounding the flame. The consumer turns the gas on full by means of the tap at the burner and regulates it until he gets the maximum light with the minimum consumption of gas. No lighting back or breakage of mantles occurs. The gas can also be turned down when required without lighting back. Cos Jour., Apr. 5, 1922, p. 50. 7 Gas Jour., Dec. 21, 1921, p. 820. Cat Jour., Oct. 5, 1921, p. 29. Additional information is available on the production of gas from straw referred to in the 1918 Progress Report. A test on a machine handling 150 pounds of baled straw gave 850 cubic feet of gas for this amount in thirty-three minutes. Sunflowers will produce 15,000 cubic feet per ton, 10 gallons of light oil, 10 gallons of tar and 640 pounds of carbon. An analysis of straw gas has shown C02--30.6 per cent, acetylene--6.4 per cent, CO--28.2 per cent, methane--21.3 per cent, H--11.3 per cent, N--3.2 per cent yielding a calorific value of 469 B. t. u. per cubic foot. In 1918 the last year for which figures are available10 the production of monazite sand in India amounted to 2,117 tons a great advance over the last pre-war year s production of 1,235 tons. The outlook is very favorable and it is. Bookseller Inventory # APC9781130707410

It seems necessary in the sale of oriental rugs to create an atmosphere which resembles the eastern setting of the rugs, and this of course means very dim lighting. The idea seems to prevail also that the same thing is true in regard to lighting for all rugs. I believe, however, that this is largely a fallacy. In the more modern homes of to-day the rugs are seen in a good light and there is just as much reason for good lighting for the display of such goods as for any other line of merchandise. In regard to furniture departments, polished surfaces are presented on every hand and unless a highly diffused lighting system is used the attempt to cut down the glare results in the use of low candlepower lamps. The absorption of light is very great in such departments also as in the case of rug departments, thus often giving the general impression of being lighted to a much lower intensity than other departments of the store. The power of example is strong, and if any store with a reasonably good standing has departments lighted in this manner other stores in carrying out their lighting schemes are impressed with the general effect and follow this example in their own cases. There is no question, however, that by the use of a well diffused lighting system increased illumination at least to a par with that of other departments will be justified by resulting sales. Human nature does not differ materially when purchasing furniture or rugs to what it does when purchasing any other kind of merchandise.

I have not had time to segregate these orders to determine whether they were for glare or for improper distribution, etc. From what I can remember, most of them were for the elimination of glare or minimizing of glare. Many other orders have since been secured, no doubt, but I have only given statistics up to the 1st of March. These orders go out, and the parties upon whom they are served are given a definite time in which to comply with the law. Manufacturers may ask for an extension of time.

It is very desirable to place a lamp so that men can read with comfort while having their shoes shined. Mr. Allen. --I have made provision for one 60-watt tungsten lamp near the cashiers desk. At the boot-black stand the illumination averages at least 2. 5 foot-candles, and considering the reflection from the walls, it would seem that there is no need for an extra lamp at this place. In regard to the use of four large main lighting units instead of a larger number of smaller units, it should be noted that when there are many lighting sources the retina of the eye contracts and hence the smaller the number of units the better the real illuminating efficiency. The particular units chosen give a good light distribution for illuminating the floor. The absorption is somewhat greater than with opal reflectors, but the real illuminating efficiency is improved by the reduction in intrinsic brilliancy. By using clear lamps the loss of useful life due to frosting has been avoided. The fixtures are so designed that a current of cool air drawn in at the bottom of the shades is brought in contact with the lamps and passes out through an opening in the fixture casing. Tests have shown that the temperature rise is well within safe limits. Mr. W. H. Blood, Jr. --The form of window lighting proposed by Mr. Daggett does not appeal to me. Fully 30 per cent of the light is lost by the use of ground glass. Equally as good effects, and in many ways a superior lighting, can be obtained by means of green shades placed close to the window so that no light will be thrown in the eyes of people on the street. In this way intense light would be obtained on the merchandise in the window. Mr. F. E. Smith. --I ask Mr. . . . This item ships from La Vergne,TN. Paperback. Bookseller Inventory # 9781130451733
