30 BULLETIN OF THE UNITED STATES FISH COMMISSION. 
of the chain of lakes in Dickinson County, with very clear and very 
deep water. It is about 6 miles long and 2 miles wide, and is consid- 
ered the only suitable lake in the State for these trout. Mr. A. A. Mo- 
sher, who deposited the fish, says that nothing has yet been heard from 
them, the long mosses and aquatic plants, which rise from 2 to 10 feet 
from the bottom of the lake, making an excelleut hiding-place for them. 
The 10,000 eggs sent to Mr. Atkins went, by some mistake, to Grand 
Lake Stream, and were reshipped to-Bucksport, Me. On arrival there 
it was found that they were partly frozen, which caused a loss of 1,575 
eggs. The total loss was about 3,000. Those that hatched were planted 
in Branch Pond or its tributaries, within the city of Ellsworth, on May 
4, 1885. Branch Pond is a tributary of Union Biver, in Hancock County, 
Maine. Up to February, 1887, nothing had been seen of the fish. In 
the spring of 1880 Mr. Atkins angled for them without success. 
The 10,000 sent to the Michigan fish commission were planted in two 
small lakes in Clare County, Michigan, the headwaters of the Tobacco 
River. 
The 5,000 eggs sent to Mr. L. S. Hill were hatched and planted in 
streams and lakes tributary to Balks Lake, Bulton’s Lake, and Buck 
Creek, a few miles out of Grand Rapids, Mich., and some were placed 
in a small body of water since turned into a trout pond. All seemed 
to be doing well in the fall of 1886, and in the spring of 1887 many were 
seen in the trout pond. 
In March, 1887, Mr. Clark reported that of the 7,000 fry retained at 
the Northville hatchery about 2,500 remained in good condition and 
were doing well, no perceptible losses having occurred since four or five 
months after hatching. 
Either no report has been given or nothing definite is known of those 
sent to Messrs. Sweeny and Dalrymple, and to Crooked Lake, in North- 
ern Michigan, where the plant was made by the Flint and Pere Mar- 
quette Railroad. 
Concerning the hatching of these eggs Mr. Maitland wrote : These 
eggs differ from the fontinalis in requiring a much larger supply of water, 
and it is absolutely necessary that they in no case be laid down so as to 
lie one above another. The water over them should not be more than 
half an inch, with a supply of 2 gallons per minute. A test experiment 
of this was made and has been repeated with the same results for seven 
successive years. They asphyxiated in 6 inches of water, temperature 
at 45° F. ; date, one week before hatching ; size of trough, 7 feet by 20 
inches. Under the same circumstances, fontinalis eggs would hatch 
perfectly. 
In Loch Leven, says Mr. John D. Quackenbos, writing from that lake 
on June 24, 1886, these trout are found upon the shoals all summer, 
and afford rare sport to the angler. As fighters they far surpass the 
Salvelinus fontinalis, and no fish can surpass them in delicacy of flavor.
