THE NEW WORLD OF SCIENCE 



In the week beginning October 3, 1918, sixty such balloons, 

 adjusted to fly between the initial and final altitudes of 15,000 

 and 25,000 feet respectively were sent up from Fort Omaha, 

 Nebraska, carrying return cards and watches, which were ar-

 as the ballast was exhausted. Thirty-four out of sixty of these 

 balloons were picked up and returned to Washington. Instead 

 of flying loo miles, one of them came down within ten miles
