Shooting rabbits from an aeroplane would be comparatively easy. I came to this conclusion while flying over North Island, which is covered with weeds and sagebrush for the most part, with hundreds of jack-rabbits and cottontails living there. At first these rabbits were terribly frightened by the aeroplane and ran in all directions to escape. They soon became used to the sight, however, and would watch the aeroplane with a great deal of curiosity. One of the big jack-rabbits, either from fright or curiosity, waited too long to get out of the way of Harry Harkness in his Antoinette, when he made a rather abrupt descent, and it was cut in two by the propeller. MAIL-CARRYING One of the most important special uses to which the aeroplane is particularly adapted is for carrying the mail. Royal mail was first actually handled at Allahabad in India last summer, during which over 6,000 letters were transferred. This service was planned to prove the great value of an aeroplane post during war time to a besieged town. A mail route via aeroplane was established on trial between London and Windsor in England, which carried several tons of mail matter. And in this country last fall Postmaster-General Frank H. Hitchcock and Captain Paul Beck, U. S. A., inaugurated the first aerial postal service regularly established in the United States, over a route between the Aero Club of America's flying grounds at Nassau Boulevard on Long Island, and Mineola, L. I. A picturesque account of this little episode is given by Frank O'Malley, who wrote: "The flying events of the day at the Nassau Boulevard aviation meet came to an end in a hubbub of joyousness among 1,500 spectators on the grounds. "Lieutenant Milling had busted the American record and was still flying for the world's record when a tall, youngish man decked out in a blue serge suit, and a gray cap, climbed into the Curtiss machine driven by Captain Paul Beck of the army. "'The Hon. Frank H. Hitchcock, Postmaster-Gen'rul of the whole United States,' the megaphone man began to holler,'will now fly to Mineola with Captain Beck to deliver the mail. Postmaster-Gen'rul Hitchcock of the United States will carry the mail-bag on his knees and drop the bag at Mineola into a circle in which will be the Postmaster-Gen'rul of I mean the Postmaster of Mineola. Ladies and gentlemen, Postmaster-Gen'rul Hitchcock.' (Much applause.) "Mr. Hitchcock wasn't around to hear all this and so didn't lift his gray cap in acknowledgment. He was far out on the field with Attorney-General Wickersham and Captain Beck. Post Office Inspector Doyle handed the Postmaster-General a mail bag containing one thousand, four hundred and forty postcards and one hundred and sixty-two letters, and Captain Beck and the Postmaster-General hiked off in a northerly direction for the high spots,
