when the train slowed up, before turning back from the Hudson, at 

 Spuyten Duyvil, the Dncks flew ahead. In order to get at the exact 

 distance and time, I wrote to the General Superintendent of the rail- 

 road, Avho kindly sent the following reply: "Referring to yours of 

 this date, relative to train, stops, and distances, Nov. 3, 1879 : The 

 train alluded to left Garrisons at 7.52 a. m., Sing Sing 8.30 and Spuy- 

 ten Duyvil 8.58 ; and the distance between Sing Sing and Spuyten 

 Duyvil is 19-fifo miles." Signed, " J. M. Toucey, Gen'l Sup't." The 

 time, then, was exactly 28 minutes, and the distance 19.56 miles; this 

 makes their rate of flight 1 mile in 1.43 minutes, or rather more than 

 a mile in a minute and a half.
