The first (113) we planted in the trees in the angle between the main road 

 and the first path to the left, within the fort, on Garden Key. The second 

 (92) we planted on various kinds of trees and shrubs about the Laboratory on 

 Loggerhead Key. The last (101) we planted in the small grove of cordia trees, 

 on the east side and a little north of the lighthouse, on Loggerhead Key. 

 The 12 remaining were left in the care of Miss Ptuth Hayden, at the Naval 

 Station at Key West, who placed them in the trees surrounding the com- 

 mandant's residence. It is to be hoped that all these colonies will flourish 

 and also that they may yield some data of interest to the biologist. 



Birds Observed on the Florida Keys and along the Railroad of the Mainland 

 from Key Largo to Miami, June 17 to Jidy 1, 1915, by Paul Bartsch. 



During the past two years lists of the birds observed in southern Florida 

 and on the off-lying keys, while making my visits to the cerion plantations, 

 were published in the Year Book of the Carnegie Institution. These observa- 

 tions were continued this year with the results noted below. This year's 

 trip was a very hurried one which left little time for search. The specimens 

 noted were seen without any special effort having been made to locate them. 

 The birds observed this year are undoubtedly the breeding bii'ds of the region, 

 since the spring migration was long past and the autumn migration had as yet 

 noi: set in. The observations made in 1913 extended from April 25 to May 9, 

 while those reported upon in 1914 were made from April 20 to April 30. 



The number of forms noted during the past two years was 76, to which 13 

 are now added, bringing the total to 89. The record published in 1914 of 

 the occurrence of the white-eyed vireo (Vireo griseus griseus) on Sands Key, 

 should, I believe, be changed to the Key West vireo {Vireo griseus maynardi) 

 the prevalent form on the Keys. 



June 17. — On a trip from Miami to the outskirts of the city taken this 

 afternoon, the following birds were observed: Gray kingbird, Florida blue jay, 

 mocking-bird, blue grosbeak, Florida cardinal, red-bellied woodpecker, ground 

 dove, turkey buzzard, and Florida cormorant. 



June 18. — A trip through lower Biscayne Bay showed several least terns, a 

 brown pelican, a man-of-war bird, and a number of royal terns, the latter 

 occupying the stakes marking the channel. 



June 20. — A walk near the Royal Palm Hotel at Miami showed the pres- 

 ence of the red-bellied woodpecker, turkey buzzards, one black vulture, and a 

 bald eagle. 



June 21 . — On a visit to Brickies Hammock, south of Miami, the following 

 birds were noted: Mocking-bird, Florida cardinal, red-bellied woodpecker, 

 ground dove, turkey buzzard, mourning dove, and Key West vireo. 



On the afternoon of same day a call was made on the second Ragged Key 

 north of Sands Key. Here we found the Florida cardinal and a green heron. 



On the same day we also visited the first Ragged Key north of Sands Key, 

 where the Florida cardinal and the Key West vireo were seen. 



Sands Key was next examined and showed the presence of the Florida 

 cardinal, the Key West vireo, and a man-of-war bird. 



On our return through Biscayne Bay in the evening we found the Florida 

 cormorant, brown pelican, man-of-war bird, and the royal terns, the latter, 

 as usual, occupying the stakes marking the channel. 



June 22. — Cape Florida: Quite a number of royal terns were seen on the 

 channel stakes, but they are by no means as abundant as they were on the 

 earlier date in the previous years. 



Passing down Hawk Channel we observed one brown pelican and two 

 man-of-war birds.
