by long continued practice, The speed with which ducks 

 fly, range from 60 to 90 miles per hour. When flying at the 

 rate of 60 miles, a duck will pass you at the rate of n feet 

 in a tenth of a second; and at a rate of 90 miles, would pass 

 16 feet in the same time. 



The following table gives the result of experiments 

 made by Alfred M. Mayer, Professor of Physics in the 

 Stevens Institute of Technology, Hoboken, N. J., taken 

 from a report read before the American Association for the 

 advancement of science, at Boston, on August 31, 1880, and 

 published in the Forest and Stream, of October 26, 1880. 



The velocity of shot was determined by a very ingeni- 

 ous contrivance called the " chronoscope." Only a portion 

 of the table is given here, being quite sufficient to establish 

 the mean velocity of shot with a given charge of powder 

 and distance:
