Budget.—The appropriation for the year 1920 was $54,891. 
An increase on August 20 of $2,934.56 applicable to salaries, and 
an issue of special revenue bonds at the close of the year to meet 
a deficit in supplies, amounting to $3,360, were also granted. 
Attendance.—The attendance, which had decreased somewhat 
during the war, has now returned to about what it was prior to 
1915. The number of visitors in 1920 was 1,994,548, an increase 
over that of 1919 of 143,973. The daily average for the year 
was 5,449. 
The total attendance at the Aquarium for the twenty-three 
years of its history exceeds forty-five millions.

Foulness of the Water of the Harbor.—Owing to the increas- 
ing pollution of the harbor, the Aquarium was compelled to in- 
stall a system of pure stored sea water several years ago. The 
use of this water resulted in an immediate improvement in the 
health of the inmates of the Aquarium. Recent experiments 
made at the Aquarium indicate that the harbor is now so polluted 
by sewage that sea fishes cannot live in it more than a few days. 
This appears to be proved by the fact that fishes carried in the 
well of the Aquarium collecting boat must be promptly removed
