fish ponds in Washington, and also for hatching the various species 
of Salmonidwe during the winter, for illustrating the fish-eultural work 
of the Commission. The following table shows the number of eggs 
received and the fish hatehed and planted:

The superintendent is charged with receiving and shipping freights 
and express matter passing through the central office. During the 
past year this involved the handling of 783 shipments and 1,004 
receipts. The general distribution apparatus is also stored at this 
station under his direction. After the distribution season is ended the 
cars are laid up at Central Station for the winter, during which time 
their machinery is thoroughly overhauled by the station machinists, 
thereby saving the Commission thousands of dollars annually. 
CENTRAL STATION AQUARIUM (L. G. HARRON IN CHARGE). 
From July 1 to September 15 the grotto was closed, it being imprac- 
ticable, on account of the high temperature of the water, to maintain 
an exhibit of salt-water specimens. 
The salt-water circulating plant was improved by the introduction 
of a new heater and the installation of an engine for use in operating 
the salt-water pumps whenever the water pressure might be too low 
to run the motor. 
A supply of salt water was obtained from the Chesapeake Bay early 
in September, and arrangements were made for restocking the 
aquarium with marine fishes and other animals collected from points 
on the Chesapeake and Buzzards Bay. About 1,000 specimens, rep- 
resenting 54 species, were secured from these two sources, and these, 
with supphes of sea-anemone and star-fish from Gloucester, Mass., 
stocked the salt-water aquaria to their full capacity. This exhibit 
remained exceptionally good until about February, when a disease 
appeared and caused the loss of a great many of the specimens. It 
attacked their fins and gillrakers, and seemed to eat the flesh from 
the spines and rays, causing the fish to refuse all of the food. Various 
remedies, including strong salt baths, were tried, but without effect,
