previously started, claim record in this annual report. 
The Biological Station was not closed during last winter, 
and will be kept open during the present winter also. 
The keeper, Thomas Jarrett, and his wife are still in 
charge. At the end of autumn (October 31st, 1890) the old 
sailing boat, ‘‘ Bonnie Doon,” which had for some time

beached for the winter. A thorough examination of her in 
the spring showed that she was really past work. Some 
of her planks were so rotten that they would not bear
