swimming in large flocks or flying one behind another in long lines. Whilst in the water they 

 could be approached but with the greatest difficulty. Later, during the survey of Simoda 

 harbor, our boats visited a small group of rocks about six miles from the shore, and designated 

 on the charts as Eock island. This served as a roosting place for these birds, as well as for 

 numerous gulls. I was not, however, so fortunate as to find the nests of the cormorants, as 

 only a small part of the rocks were accessible, and they had selected as their resort the inacces- 

 sible bluffs towards the seaside."
