GLOW Of FIREFLY
MAY LIGHT HOMES Resources Report Visions Possibility of Electricity Substitute in 1957. BY THOMAS R. HENRy! Cheap synthesis of luciferin, the chemical substance responsible for the light of the firefly and the cheapest and most efficient illumination in na ture, is seen as one of the possibilities of the next two decades in the report on scientific trends presented to Pres ident Roosevelt this week by the Na tional Resources Committee. The natural luciferin of the firefly and other luminescent animals is oxi dized or burned when it comes into contact with oxygen, but all the energy is given off in the form of visible light. None takes the form of heat energy. This prospective development, the re port points out, may do away with electricity and other sources of arti * flcial light, which at best are very in efficient and costly. Best Lights Wasteful. The most efficient tungsten lamps, the report points out, yield only 15.5 per cent of the current used in the form of light. This means only a little more than 2 per cent of the total energy of the coal used to produce the electric ity. The cold light of the firefly is 96.5 per cent pure light. The luciferin would involve no fire risk, wiring or fixtures. There may be luminescent paints which will store up sunshine during the day and give it off in the form of light at night. Great strides in the improvement of artificial illumination, the report points out. are being made in vapor lamps. Bulbs filled with mercury or sodium vapors produce must greater efficiency, but give out unpleasant blue or yellow glows. But, says the report, “it is entirely reasonable to assume that in the near future we may closely duplicate the sunlight spectrum by a combination of these and other vapors In a single highly efficient lamp,’’ Better Eyes in Prospect. An outstanding development in the field of illumination, it is stressed, is the accurate determination of the lighting requirements for the per formance of various tasks. The results of this work will be manifested in better eyesight for future genera tions. Already many schools are equipped with photo-electric cell hook ups w'hich automatically switch on class room lights when illumination from outdoors falls below a predeter- , mined point. Perhaps the most picturesque de velopment forecast for the future is the floodlighting of main highways all over the United States. Says the report: "About 80 per cent of the traffic is in the daytime and 20 per cent at night. This means that the tremendous investment in our high way system is being wasted during the hours of darkness. People try to avoid night driving because they realize that the probability of their being killed or killing some one else is many times as great as it is In the daytime. Lighting the highways will stimulate more night driving and thereby relieve the daylight conges tion. A trip will be changed from a nightmare to a pleasant experience." A significant development, it is stressed, will be the probable decrease In hold-ups on country roads.

BACKGROUND— Last April the United Chocolate Workers, a C. I. O. affiliate, called a sit-down strike In the Hershey plant. The plant was closed but a week, because farmers, deprived of a market for their milk, banded with non-strikers to drive out the sit-downers after a bloody battle. HERSHEY, Pa., July 23.—Union leaders charged today that a crowd threatened to tar and feather them at the close of a meeting last night a few miles from the Hershey choco late plant, where angry farmers and non-striking worker* routed sit-down strikers in April. The mass meeting was held by the United Chocolate Workers, an affll ADVERTISEMENT.

O., said a crowd of approximately 30 men re fused to let him and his stall leave the meeting place for half an hour. “After half an hour of threats during which we momentarily expected to be assaulted,” Edelman said, “we finally reached our cars and dro^fe away. The crowd followed us for sev eral miles, shouting and blowing their horns.” The united workers after the April strike last to an unafflllated group in a National Labor Relation Board elec tion to select a collective bargaining agency.
