Now, in taking and impregnating the spawn, I use two men ; while 

 one handles the female the other handles the male, and I find by so 

 doing we have but a small percentage of unimpregnated eggs to re- 

 move, while by using both at the same time we follow nature as 

 nearly as it can be done artificially. We have to transport the spawn 

 of the whitefish for our hatchery from one to two hundred miles. 

 We use what is termed the dry process for transporting them, having 

 an attendant constantly with them to handle the boxes very carefully 

 whenever it becomes necessary to move them at any time while en 

 route to their destination. 



I also take great pains to get the temperature of the spawn in the 

 boxes equal to the water in the hatchery before placing them in their 

 proper place in the hatching boxes. 



I use the Holton Patent Hatching Box which I consider the only 

 proper appliance for hatching whitefish to insure a genuine success, 

 all others that I have seen or heard of have been a failure to a greater 

 or less extent. I use plenty of water running through the boxes to 

 cause enough current to nearly lift the eggs from the trays, or, in 

 other words, I use as much as possible without lifting them. I use 

 the water from Lake Michigan, the same being pumped directly 

 from the lake into the hatchery, therefore we have the same tempera- 

 ture of water that the spawn have that is deposited naturally by the 

 fish in the lake, which I consider necessary to produce good healthy 

 fish, such as will 'thrive and prosper. In fact my experience in 

 hatching this variety of fish in spring water and also in lake water 

 has convinced be that those hatched in spring water come out pre- 

 maturely and cannot survive more than a short time. 



I find it also necessary to remove all the unimpregnated eggs as 

 soon as possible, also to wash and cleanse them from every particle 

 of glutinous matter, after which I have no trouble with their matting 

 or sticking to the trays and then by using due diligence to business 

 I never fail, and success crowns all my efforts. I have also been 

 experimenting in feeding a few of the whitefish of thej last two 

 season's hatchings and have succeeded in keeping some forty of the 

 hatch of 1877 until the present time which now measure from six to 

 seven inches in length. I also have about the same number from 

 this year's hatch which are growing finely, and are in better condi- 

 tion and more thrifty than those of last season were at their age 

 which is no doubt owing to the improvement in feeding, which we 

 have made since last season. The great trouble in raising whitefish 

 artificially, is in teaching them to feed which requires both 

 patience and perseverenqe. We commence when the fry are Irom
