Uncle Sam Counts Noses
HOW AMAZING MACHINES HELP TAKE THE CENSUS LAST month the census taker came to call. He unfolded a big white sheet of paper and began firing questions. Name? Age? Birthplace? And so on until he knew all the answers, and departed with his pencil-checked list. All over the country, 120,000 fact finders were doing the same. So far as foresight in planning could provide, they overlooked no dwelling's occupants; they even visited auto trailers, marking them with stickers to avoid recounting!

The Making of a "Funny"
By EDWARD W. MURTFELDT RESEARCH workers studying the reading habits of newspaper buyers have found out that more people look at the "funny" pages than at any other single section of a newspaper. Yet few cartoon enthusiasts realize how elaborate is the process that brings a comic from the brain and drawing board of a cartoonist through the involved stages of coloring, engraving, mat making, stereotyping, and printing to its final form as part of a published paper.

New Patents Forecast Your 1942 Car
THAT car you'll be buying in 1942—what will it look like? Will it have the engine in the front or in the back ? Will it be heavier or lighter, longer or shorter, more or less expensive than the car you're driving now ? Startling is the only word for the answers to these fascinating questions, as disclosed by an automotive survey just completed by Popular Science Monthly. Whispers of radical changes and innovations in motor-car design are in the wind, and the recent granting of a series of important automotive patents, every one of which covers a car having its power plant in the back instead of the front, heralds the dawn of a new era in automotive transportation.

New Boom in Gliders
Thrilling Aerial Sport Gains Wider Popularity Through Knockdown Kits That Enable Anybody To Build His Own Sailplane, Buying All the Materials on a Pay-as-You-Go Plan By ANDREW R. BOONE SOARING on wings assembled in back yards and home workshops, hundreds of glider enthusiasts are piloting their own sailplanes. Bought on the installment plan, their ships come in knockdown kits. Piecemeal buying enables boys and men alike to build gliders. As a result, flying without power is sweeping the nation. More than forty meets will be staged this year, from the big national events like the one held annually at Elmira, N. Y., to small sectional competitions on farm lots, desert lakes, and mountain pastures. Two hundred clubs have been formed with 2,000 members. Aside from the kits, would-be soarers need purchase few accessories. Tow rope, a couple of wrenches, air-speed meter, and a sensitive variometer fill the bill. In many towns groups club together, building their own soaring planes and cooperating in flying. At a cost far less than that of a powered plane, their members enjoy the thrills and pleasures of flying. Danger of injury is less, too, for they can land the light craft at comparatively slow speeds.
