or 52 per cent. The remaining eggs prodnced 2,500 young salmon, and 

 they were turned into the Castalia Ponds, which discharge by a stream? 

 three or four miles long, into Sandusky Bay. The water of these ponds' 

 and of the springs which supply them, is very warm, between 50 and GO 

 degrees,* is of remarkable transparency, and highly charged with min- 

 eral matter in solution. 



The eggs sent to Michigan numbered 43,200, They were received 

 by i^. W. Clark, who hatched them oat ITir the Commissioners of Fish" 

 eries, at Clarkstou. The eggs were pacli;ed up March 10, and despatched 

 on the 11th, but did not reach their destination until the 17th. Not over 

 5 per cent, of them were found dead on unpacking, t The temperature 

 of the water was 34° F. at the time the eggs were placed in the boxes, 

 and it continued about the same until March 25, after which it grew 

 gradually warmer until it attained the ordinary summer temperature of 

 600 p^ tijq figii were all out about the middle of April, to the number 

 of 30,000, there having been a loss of 30 per cent, in hatching. The dis- 

 tribution of the young commenced May 14, the number having mean' 

 while become reduced to 19,500, making a total loss of 23,700, or 55 per 

 cent. The 19,500 fish distributed were put into the Kalamazoo, Saint 

 Joseph, Grand, Muskegon, and Manistee Eivei's, tributary to Lake Mich- 

 igan, and the Au Sauble Kiver, tributary to Lake Huron, also into Or- 

 chard, Walled, Whittemore, Diamond, and a few smaller lakes. Some 

 of them are reported to have been since seen in Diamond Lake in good 

 condition. 



The eggs awarded to Wisconsin, 40,724, were sent by express in three 

 packages, that were dispatched as follows, viz : 9,324 February 24 ; 

 18,400 March 3; and 13,000 March 10. In the first package 100 eggs 

 died on the way ; in the second 350 ; and in the third 1,000 ; in all 1, 450- 

 The subsequent loss in eggs and newly-hatched fry was about 19,500. 

 There were hatched and saved about 19,000 fish. The first of them came 

 out on the 13th of March, and all were out the first week in April. The 

 hatching was conducted by Mr. H. F. Dousman, at Waterville, Waukseha 

 County, in spring-water having a temperature of 48° F. Early in the 

 spring the young salmon were distributed ; 7,000 were put into Meno- 

 monee River, tributary to Green Bay ; 1,000 into Oconomowoc Lake ; 

 and 11,000 into Milwaukee River. The latter were intended for the 

 Kewaunee River, which lies one hundred miles farther north, but an ice 

 blockade compelled the change.|

t Letter of N. W. Clark. Mr. Clark remarked that the largo caus contained more 

 dead eggs than the small ones, and concluded that the pressure on the under layers, 

 consequent on the large size of the boxes, caused the injury. 



t Letter of H. F. Dousman. Mr. Dousman reports that one of these fish is supposed 

 to have been caught late in August, on the Menoraonee River, one hundred and fifty 

 miles above its mouth, by one Cruicksliank, a native of Nova Scotia, who was ac- 

 quainted with the .species and pronounced the fish a salmon, on the strength of its 

 appearance and taste, ignorant of the fact that young salmon had been distributed 

 there. The specimen was estimated to weigh G ounces.
