are dim or obliterated be repainted. And it is even more necessary that lines be ex- 
tended from these numbers to the beach line in the large massed areas. White paint 
placed on the tops of the rocks in a line would be sufficient. On Reef Rookery, for 
instance, the numbered rocks are so far back from the beach line that the number of 
harems between two can not be determined. In a few places additional numbered 
rocks are needed. On the southwest end of Gorbatch the numbered rocks do not 
extend far enough. 
In 1916 it will also be necessary to build some towers. The harems have spread over 
some of the only available observation points on Reef, Tolstoi, and Zapadni. With- 
out some elevated position it is not possible to count the beach line harems and those 
that have extended out over the table-land. On some of the rookeries there is drift- 
wood, which may be used to construct elevated stations. Artificial divisions of the 
rookeries are of great importance in making the harem count.

The percentages of gain were about what were expected from the 1914 investigation. 
Only one rookery as a whole lost; this was Little East on St. George, and it had only 
one harem to lose. When the details of the rookeries are considered and the counts 
of each section compared with the charts of 1914 there is seen to be a shrinkage in many 
of the scattered harem sections of several rookeries. This shrinkage is caused by the 
dying off of the old rookery bulls. It seems to be a law among the young bulls to flock 
to the massed areas, and consequently these made the greatest gains in harems. Only 
when a young bull is completely whipped does he go away by himself. Then he hauls 
out on the beach away from all harem bulls. Sometimes cows will come to him there 
and a new rookery section is started. By far more new areas were started in 1915 than 
showed a shrinkage. Rookery area once abandoned by the dying off of the old bulls 
stands no more chance of becoming occupied again than any other suitable isolated
