had already flown from Key West on the above flight, were again captured and 

 sent in a hooded cage to Key West; they were released in Key West harbor at 

 2 p. m. (See table 10.)

Since Bird Key is only 6.5.4 miles from Key West, the time (3'' 45"") is not 

 very rapiti when compai'ed with that in which the homing pigeon coukl cover a 

 short distance like this (at the rate of 1,200 to 1,600 yards per minute). 



ATTEMPTED FLIGHT FROM NEW YORK AND EN ROUTE. 



On the afternoon of May 19, 1910, birds for a New York-Tortugas flight 

 were captured. They were taken to Key West, leaving the island at 8 a. m., 

 May 20, on the Vellela. It was stormy and the VeUela got into Key West too 

 late to catch minnows for the trip. While we felt sure that this doomed the 

 expedition to failure, nevertheless we purchased a large fish, which we cut up 

 into strips, substituting it as a food supply in place of the minnows. The 

 Mallory boat Concha left Key West harbor the night of May 20 at lO"" 30", 

 the birds being in charge of Mr. Wilson. The cage was hooded and in addition 

 was carried in the hold of the vessel. The first lot of birds was marked as 

 shown in table 11. 



Table 11. — Night release. 



Sooty No. 1. Yellow, line down back, 1 dot on breast. 



Sooty No. 2. Yellow, both wings splotched. 



Sooty No. 3. Yellow, right wing splotched. 



Sooty No. 4. Yellow, 3 vertical bars on left wing. 



These 4 birds were released at 7'" 30™ p. m., 365 miles from Bird Key, at 

 night (immediately after twilight had disappeared). Only 1 bird fiom this 

 lot returned, requiring appro.\imately 4 days. On release, 1 of the 4 birds 

 started due south and the others southeast. The weather was fair until the 

 24th. On the evening of the 24th a heavy southeast wind set in, which made 

 it unpossible for the birds to make Bird Key. The rest of the l)irds were 

 carried to New York. They were marked as shown in table 12.

 4'- 30", in a fog. On release they left the ship and flew to a distance of 200
