86 REPORT OF COMMISSIONER OF FISH AND FISHERIES. 
It should be stated that, in the report just referred to, the statement 
is made that in June Mr, Davis, fish-culturist at the Green Lake Station, 
witnessed the killing of four landlocked salmon by a horse-leech in one 
of the interior hatching-troughs, the deaths occurring within a few 
minutes’ time. The fish of all kinds on hand June 30, the end of the 
fiscal year, are represented in the statement below:

The station being about 4 miles from the railroad point, and the traps 
at opposite ends of the lake being several miles apart, connection was 
established by renting a small steam launch belonging to the Reed Pond 
Land and Navigation Company. On the breaking of the launch’s shaft, 
November 5, the station horse and small boats were used instead. 
In December the air temperature on three or four mornings dropped 
below zero, the water in the hatchery descending as low as 34° F., the 
maximum for the month being 38°. An increased flow of water through 
the supply conduit, as a general protection against freezing, caused 
overflowings and the formation of heavy icicles upon trestlings where 
the ravines are spanned, requiring at times much labor in cutting 
away the accumulations. The first snow permitting sleighing fell Jan- 
uary 10. Connection with the post-office was effected daily by sleigh 
over the ice on Green Lake after January 5, continuing until late in 
April, the ice being melted May 12, when steam-launch service was 
resumed. The air temperature in January was as low as—14°, the 
water in the hatchery ranging from 34° minimum to 36.5° maximum. 
In February one snow-fall of 27 inches occurred. In that month a 
temporary structure was stored with 25 tons of ice of 24-inch thickness. 
The April water temperature was 37.5° minimum and 46° maximum. 
When the ice broke up in the lake, May 6, the water rose above the 
station wharf, but by the end of the month it had fallen over 2 feet. 
The minimum hatchery temperature for May was 44°, maximum 64°, 
average 54.59. Toward the end of the year negotiations were pending 
for renting a larger boat for service on Green Lake. 
GLOUCESTER STATION, MASSACHUSETTS (A. C. ADAMS, MASTER OF THE SCHOONER 
GRAMPUS, IN CHARGE). 
General overhauling of the station in preparation for the winter’s 
operations commenced December 13, cold weather delaying this work 
considerably, the supply pump not being in readiness until January 10.
