"Thanks for the harmonica you gave me for Christmas," little Joshua said to his uncle the first time he saw him after the holidays. "It's the best present I ever got."

"That's great," said his uncle. "Do you know how to play it?"

Earth's curvature photographed

In 1930, a photograph showing the curvature of the Earth was exhibited in Cleveland, Ohio, at a joint session of the American Association for the Advancement of Science, holding its annual convention, and the Society of Sigma XI. According to the New York Times report, it was the first photograph to show the Earth's curvature. The picture, taken from an airplane flying at 21,000-ft over South America by Capt. Albert W. Stevens of the U.S. Army Air Corps, used super-sensitive panchromatic photographic film to record an image of an area larger than some States.

Mees, research director at Eastman Kodak Company said it was taken with a 1/50 sec. exposure.*«[Image: taking photographs from a biplane.]
