salmon, and his by that of the shad, and thus was another mistake corrected. The 

 landlocked salmon straggled along' a tew years later, but his name has siuee been 

 struck from the list. 



In the summer of 1880 the Detroit hatchery was remodeled and the last of the 

 Holton boxes discarded and their places supplied with the Chase jars, giving a total 

 of 300 jars and a hatching capacity of more than 30,000,000 whitefish fry. Six of 

 these jars were exhibited by Prof. Baird at the International Exposition at Berlin, 

 and Mr. Chase secured the "golden medal of honor" for the invention. About this 

 time the trout and salmon in the ponds at Pokagon began to sicken and die, and an 

 analysis of the water demonstrated that it was not suitable for the trout work; and 

 thereupon ground and water was rented at Boyne Falls, where, through the liberality 

 of Hon. Thomas S. Cobb, of Kalamazoo, a temporary hatchery was located. After a 

 season's use, however, the dam was carried away by a freshet and the hatchery aban- 

 doned. The carp were retained at Pokagon for a while, but were soon after removed 

 to Gleuwood, where the carp-hatchery has since been carried on under the supervision 

 of Mr. Worden Wells, in ponds belonging to him, and with unvarying success. 



The whitefish plant for 18S0 was 10,095,000, and for 1881 only 3,000,000. The 

 cause of the falling off was the difficulty in procuring the ova on account of storms 

 and the failure of the Detroit river fishery, where the fish had theretofore been obtained. 

 About this time the methods of securing the ova w r ere much improved under the 

 suggestion and experiments of Oren M. Chase, who found it feasible to retain the 

 fish in small crates, through which the water flowed freely, and to handle the fish 

 from day to day and take the eggs when ripe, thus making a great saving of the eggs 

 and resulting in but trifling injury to the adult fish. 



In July, 1881, the trout station at Paris, Mecosta County, was located on Cheeney 

 Creek, and about 40 acres of land and the meander of the creek, L5 rods wide, across 120 

 acres more, were purchased. Here, in the early fall of that year, was built a trout 

 hatchery, 20 by 00 feet, a dwelling-house and barn, and the hatchery and ponds at 

 Pokagon were abandoned. 



The principal trout work of the State has been conducted at the Paris station ever 

 since without any serious drawbacks. The work, however, has now about reached the 

 limit of the water supply, and one neighboring stream has already been brought over 

 in pump logs, and it is contemplated doing the same with another. 



The whitefish plant of 1882 was upwards of 18,000,000. That spring the experi- 

 ment was first made with the wall-eyed pike, and a plant was made of 1,120,000. 



The board had some difficulty with Superintendent Portman, and in September, 

 L882, he was succeeded as superintendent by Oren M. Chase. Mr. Chase served until 

 November 11, 1883, when he was drowned in Little Traverse Bay while in the per- 

 formance of his duties, sacrificing his life in his zeal for the work. Walter I). Marks 

 was then made acting superintendent until March 26, 1884, when he was regularly 

 appointed superintendent, and continued to act in that capacity until the early part 

 of 1803, when he resigned. Mr. Marks was an early pupil of the veteran Seth Green, 

 and was a man of large experience in handling and breeding fish. He was full of 

 resources and always found someway out of every difficulty that beset his work. 



January 1, 1883, Eli P. Miller retired as commissioner at the expiration of his term, 

 and John II. Bissell, of Detroit, was appointed his successor. The work had reached 

 a somewhat low ebb at this period and needed just such an energetic, thoughtful, and
