or 5. per cent. The reraainino- ego-s produced 2,500 young salmon, and 

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

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

 and of the springs which supply them, is very warm, between 50 and 00 

 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 ^. W. Clark, who hatched them out for the Commissioners of Fish- 

 eries, at Clarkston. The eggs were packed 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 -rew 

 gradually warmer until it attained the ordinary summer temperature of

 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 Eivers, tributary to Lake Mich- 

 igan, and the An 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 o-ood 

 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. Jn the first package 100 egc^s 

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

 The subsequent loss in eggs and newly-hatched frv 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 48o F. Early in the 

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

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

 aiid 11,000 into Milwaukee Eiver. The latter were intended for the 

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

 blockade compelled the change. J

tLetter of N W. Clark. Mr. Clark remarked that the large cans eontained move 

 dead eggs than the small cues, 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 Meuomonee River, one hundred and fifty 

 mdes above its mouth, by one Cruickshank, a native of Nova Scotia, who was ac- 

 quainted with the species and pronounced the fish a salmon, on the stren<rth of its 

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

 tuere. Ihe specimen was estimated to weigh 6 ounces.
