THE investigations of the marine life and physical conditions 
of the waters of our coast, under the auspices of the U. S. Com- 
missioner of Fisheries, Prof. S. F. Baird, was continued dur- 
ing the past season, under even more favorable circumstances 
than during the two previous years. This year the headquar- 
ters were eatabliahed’ at Peak’s Island, at the entrance of the » 
harbor of Portland, Maine, and about four miles from the city. 
1s proved to be a very favorable locality, on account of its 
great loss of time; and to take advantage of favorable 
weather for longer trips to the deeper waters outside the bay 
he shores and purity of the water, also proved to be numer- 
ous and interesting. 
€ scientific party was quite large during the greater part 
of the time while active operations were carried on.
