OEUISB OF THE STEAMER COR WIN. gl 



On the 10th of June I went to Otter Island in compliance with your instructions, for the pur- 

 pose of protecting that place from marauders. 



While there I made a collection of specimens for the Smithsonian Institution, in obedience to 

 your verbal orders. The collection, which is marked "Coll. J. E. L., U. S. S. Corwin," is herewith 

 transmitted. The following is a list of the specimens, corresponding to the numbers they bear:

Although Otter Island is visited by myriads of birds, the number of species is very small, 

 embracing not more than twenty-five, which includes migratory Hocks and s^tiagglers. It is an 

 excellent place for studying the habits of such birds as breed there, and any question in regard to 

 them could be satisfactorily answered by observation. 



Some of the eggs in this collection are rare among naturalists, by reason of the inaccessible 

 nature of the nests. More of the same kind could be obtained in that place by any one jiossessed 

 of a little experience in scaling the face of cliffs and a knowledge of the habits of the birds found 

 there. I secured a number of chicks of Frater corniculata and F. cirrhafa, as well as of the 

 Phaleris psittacula and Simorhynchus cristatellus, but, with the exception of the accom]);)nying 

 specimens, all spoiled for want of proper facilities for drying the skins. These are exceedingly 

 rare, probably altogether unknown. 



All of the birds which came under my observation were remarkably ])ersovering in their 

 eflbrts to propagate their species, and all would lay fresh eggs to replace those which had been 

 removed. In July I removed from the nest of a gray eared finch the half'-tlcdged young brood. 

 The mother laid five eggs within a week, and I then removed them, as well as the nest. There- 

 upon she built a new nest and deposited two more sets of eggs. Not until the last was taken 

 away did she desert the place. The guillemot's eggs were to bo found on outlying rocks as early 

 as June 10, and were replaced as fast as removed until the first of August. Even that shy bird, 

 the horned puflfin, would lay a second egg upon the first being abstracted, and when the female
