the entrance of water. During the summer of 1876 Mr. 

 Wihiiot patented this can, covering the manufacture of it 

 in either wood or metal. It was the summer of 1877 that Mr. 

 Chase patented his glass jar for the hatching of whitefish 

 eggs. This will show that we in Canada, as well as Mr. 

 Chase, were at that time working on a plan for the hatching 

 of whitefish eggs in bulk and in large numbers. 



I claim the credit of being the first to hatch pike perch 

 eggs. Our first collection of the eggs of the pike perch was 

 made April 2, 1876, on Saginaw Bay and were taken to the 

 Sandwich hatchery. We lost the entire first lot and I re- 

 turned to Bay City to secure a second supply, from which 

 we hatched quite a sprinkling of fry. After liberating the 

 same, we went to the St. Clair River and collected eggs as 

 late as May 24. From this collection our hatch was more 

 successful than from the eggs procured at Bay City. We 

 placed the eggs on the trays we had for the hatching of 

 whitefish spawn. On account of their adhesive qualities, 

 it was necessary to lay them on the trays in order to 

 give them circulation. One day after we had a heavy 

 storm and the water was very roily and dirty, we noticed 

 that after the eggs had been run through a screen and were 

 placed on the trays in a loose condition, the water caused 

 the eggs to separate and we experienced no more of the 

 trouble I mention above. This discovery was made in the 

 spring of 1880 and since then we have always used either 

 clay or black mud to roil the water when the spawn was 

 placed in tubs for washing and hardening before being put 

 on trays for shipment to the hatchery. 



It also seems apropos for me to mention at this time 

 that I think I was the first to transport and confine black 

 bass in ponds for natural production. We secured bass in 

 the spring of 1873 in the Bay of Quinte. at Belleville, On- 

 tario, and transported them to the ponds at Newcastle. I 

 remember as well as though it occurred yesterday that the 

 first black bass fry were hatched on the tenth day of June. 

 This work was continued during 1874 and 1875.
