GREEN Lake SraTion, MaAIngE (H. H. Buck AND SEYMOUR BOWER, SUPERINTEN- 
DENTS). 
This station being new and incomplete, the year opened with improve- 
ments in progress. Mr. H. H. Buck was in charge until August 31, his 
resignation having been tendered in April, but remaining unacted upon 
owing to delay attending the selection of an efficient successor. He 
was followed by Seymour Bower, who was appointed from the foreman- 
ship of the Put-in-Bay Station, Ohio, and arrived for duty September 
12. Mr. Bower’s services, however, being solicited by the commissioners. — 
of Michigan, he tendered his resignation May 8, in order to accept the 
superintendency of the fish-cultural operations of that State. Owing 
to the inconvenience of providing a competent successor, Mr. Bower’s 
services were retained until June 30. On his departure affairs were 
temporarily put under direction of the foreman, W. H. Munson. 
Fry resulting from the April hatching and on hand at beginning of 
the fiscal year, by estimate, were as follows: Landlocked salmon, 60,000; 
Loch Leven trout, 16,000; Von Behr trout, 10,000; total, 86,000. 
During July they underwent but little loss, but in August many 
deaths occurred. In September active measures were instituted with 
a view to checking the mortality. The changes were in the nature of 
increasing the depth of water in the rearing-troughs from 2% to 4 inches, 
daily cleaning with serub brushes and salt, increasing the flow of water 
through troughs, and more systematic and careful feeding. The num- 
bers, by count, in December were but 4,903 landlocked salmon, 1,805 
Loch Leven trout, and 1,252 Von Behr trout. Subsequent losses were 
trifling, there being but 14 dead removed in the four months following. 
The maximum water temperature in July was 82° F., in August 709, 
and in September 68°. During the four months’ period just referred 
to there were no deaths among the 3,800 landlocked salmon hatched in 
April, 1891, held in the reservoirs. On May 5 the fish of April, 1892, 
were again counted and transferred from rearing-ponds to new earth 
ponds, the numbers being, landlocked salmon, 4,656; Loch Leven trout, 
1,688; Von Behr trout, 1,042; total, 7,386. 
In April there were shipped alive to the World’s Fair by Car No. 3° 
100 of each kind of trout and 300 of thesalmon; also, 200 of the salmon”
