OPEKATIONS AT NORTHVILLE AND ALPENA. 



977 



haps— escaped through a hole made in one of the crates by floating 

 drift-wood. 



For the successful confinement of immature whitefish, it is absolutely 

 essential that the floating crates be placed within protected inclosures, 

 in pure water of suitable depth. 



AT THE NOETHVILLE HATCHERY. 



The first whitefish eggs were received at this station, from Lake Erie, 

 November 14, arriving in good condition. There were four cases, filling 

 eighteen McDonald jars. More eggs were expected on the 15th, but 

 the steamer which brought them was windbound, and they did not 

 arrive at the hatchery until the 17th, when they were found to be badly 

 trozen, and could not be removed from the trays until thawed. We 

 found an unexpected difficulty in the use of the closed jars. Air would 

 find its way into the jars, forming bubbles which passed rapidly 

 through the tubes, conveying many of the eggs into the tank. We had 

 considerable trouble trying to remedy this evil, and occasionally found 

 a jar entirely emptied. After considerable experimenting we overcame 

 this trouble by so arranging the jars as to increase the water pressure. 



The last lot of eggs direct from the fishing grounds was received De- 

 cember 1, making 25,000,000, which, with 35,000,000 received in several 

 installments from the Alpena hatchery, made the total number handled 

 at this place 60,000,000. Of this number, about 12,000,000 were shipped 

 to various points, and 8,000,000 lost in various ways; the total number 

 of whitefish hatched at this point was therefore 40,000,000.

It is to be regretted that all recipients of eggs do not acknowledge 

 receipt of same, stating condition on arrival and other particulars. All 

 reports received, including those from New Zealand and Germany, were 

 very favorable. The former shipment left Northville January 8, and 

 was accompanied by me to Omaha, whence it went by express to San 

 Francisco, in care of E. J. Creighton, arriving there January 13; thenoe 

 by steamer to New Zealand, arriving Februarv 16.
