Adjustable Sun Glasses Regulate Light

The sun spectacles utilize special light-polarizing glass (P.S.M., April '36, p. 20). Each eye of the wearer looks out through two special lenses. The lens nearest the eye is stationary, while the front lens can be rotated by pushing a small button on the bridge of the spectacle frame.

He Runs a Hotel for Bats
PLAYING host to 250,000 bats is the queer but profitable hobby of Milton F. Campbell, of San Antonio, Tex. His lakeside bat hotel, a tall wooden tower shaped like the base of a windmill, is the outgrowth of experiments begun years ago by his father, Dr. Charles A. R. Campbell, at that time city bacteriologist of San Antonio. Believing that bats would rid the area of malaria-carrying mosquitoes, Dr. Campbell spent years trying to induce the creatures to settle in a wooden roost which he constructed near the city sewage plant. Finally, by means of ear-splitting phonograph records, which drove the bats from their accustomed haunts, he effected their transfer to his specially constructed tower.

Horse-Meat "Worms" Fool Frogs
TRICKING frogs into eating horse meat by making them think it alive is the solution worked out by H. L. Parker, of El Monte, Calif., for the problem of diet in domestic bullfrog breeding. For twenty years, Parker has been experimenting in raising frogs as a food delicacy. Recently he decided to try feeding his frogs on a horse-meat menu, since he found it practically impossible to provide the frogs' natural live diet of vast quantities of minnows, insects, and earthworms. He contracted with the owner of a near-by lion farm for a supply of horse meat, the regular food of captive lions. This he chopped into strips about the size of worms and tossed into his concrete frog tanks.
