It must be the heat, Wash. D.C. Congressmen have been blinking into cameras since the opening of the session, Jan. 3, and now they have started "shooting" each other. This photograph shows, from the left, Rep. Gerald Boileau, Progressive of Wis.; Rep. Louis C. Rabaut, D. of Mich., and Rep. Paul Kvale, Farm-Labor of Minn. The Congressman with the candid camera was industriously banging away on the floor of the house when he was informed that he was breaking the rules. So he went outside, as the session was almost over anyway, 8/23/35

New deal for Old Dobbin. Rep. Percy L. Gassaway (cowboy and D. of Okla) isn't letting the Wash. heat wave deter him from getting ready to promote his own scheme for bringing back prosperity. He is giving Congress a week from Monday to perfect a plan. If Congress falls down, Cowboy Gassaway is going to work on a multi-ramified program which in general specifies the return of the horse and fewer automobiles. In one hour his week on a D.C. street is counted 1800 cars. "That's whats wrong!" he suggests. People will buy a gallon of gas when they have no "bread" or likker in the house." Gassaway is enjoying his electric fan while he dictates to his secretary, 7/6/35

Sun refuses to be harnessed, Washington, D.C., September 8. The scheduled exhibition of Dr. Charles G. Abbott's sun ray machine was ruined today because there was too much sun. The intense heat, after being concentrated melted the solder connections. Dr. Abbott, the inventor, then went ahead to explain his device which is said to be capable of operating a half-horsepower steam engine by the sun's heat. The exhibition was held in honor of some of the delegates to the Third World Power Conference which is now being held here

Putting tire into curing mold. From the vacuum expander, the potential new truck tire is taken to this "watch-case" curing mold in which it is baked under high heat and pressure for a long time. The exact time and temperature varies with the type and size of tire. The airbag inside the carcass is filled with live steam during this process so that heat is added from both inside and out. The mold contains the tread pattern, or design, as well as all markings which will appear on sidewall. Under this heat and pressure the rubber turns semi-liquid, and flows into every crevice, completely bonding the rubber processed fabric carcass to the cushion, the cushion to the tread. After this operation it is now one unit--a complete tire. Firestone (General) Tires, Akron, Ohio
