48 THE FUR SEALS OF THE PRIBILOF ISLANDS. 
In the interval the offices of reproduction are accomplished. The females come and 
go from the feeding grounds at intervals, caring for their young. The younger males 
spend most of their time resting on the sand beaches, visiting the sea irregularly. In 
November the females and young of the year leave the islands. The males, especially 
the bachelors, remain until December and even January, in mild seasons probably not 
all leaving the vicinity of the islands during the winter. 
THE LIMIT OF MIGRATION. 
The adult males and the older bachelors spend the winter in the Pacific Ocean, 
somewhat below the Aleutian Islands, and eastward in the Gulf of Alaska. The 
younger males go farther south. The pups probably reach the latitude of Cape Flat- 
tery. The adult females go farthest south, being found as low down as the Santa 
Barbara Channel, off southern California. 
ITS COURSE AND DURATION. 
The southward trip of the seals must be rapid and more or less direct to the 
turning point. The females do not leave the islands much before the middie ot 
November, but are taken in the latitude of southern California early in December. On 
the return trip the movements of the animals are slower, the remainder of the winter 
and spring being occupied in the northward journey along the coast, which they follow 
at a considerable distance offshore. In December, January, and February they are 
found off the coast of California. They are in the neighborhood of Cape Flattery and 
Vancouver Island in March, April, and May; and in May and June they are found 
in the Gulf of Alaska and along the southern coast of the Aleutian Islands. They 
reach the islands at various dates according to the different classes of animals. 
In this outline of the movements of the seals at sea only the general course of the 
herd as a whole is traced. A more detailed account will be found in connection with 
the migration chart prepared by Mr. Townsend and published in Part III of this 
report. In Mr. Lucas’s account of the feeding habits of the animals, also in Part ITI, 
the movements of the seals on their summer feeding grounds are more {fully given.
