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-cultui'ist at the Green Lake Station, 

 "witnessed the lulling" of four landlocked salmon by a horse-leech in one 

 of the interior hatching-troughs, the deaths occurring within a few 

 minutes' time. The iish 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 Comxjany. On the breakiug 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 oi^ f., the 

 maximum for the month being 38'^. An increased flow of water through 

 the supply conduit, as a general protection against freezing, cauvsed 

 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 i)OSt-oftice was eftected 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 30.5° 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 temi^erature was 37.oO minimum and 40'^ maximum. 

 When the ice broke up in the lake. May G, 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 54.5°. Toward the end of the year negotiations were pending 

 for renting" a larger boat for service on Green Lake.
