became evident to the Federal and State governments, as well as to those dependent upon this industry for a livelihood, that decisive steps ought to be taken toward providing against the extermination of this valuable food-fish.Artificial hatching was commenced that year with the object of restocking the Great Lakes. The work progressed only in a limited way up to 1892, when the output of both the United States and Michigan FishCommissions reached something like its present proportions. During the season of 1895 the United States Fish Commission station at Northville secured over 11,000,000 lake-trout eggs. As indicative of the success attending the plants of lake trout, it may be remarked that for a short period during the season of 1896 the fishing-boats, which had been working to their fullest capacity, ceased operations, the market being glutted and the remuneration not being commensuratewith the labor, hardship, and capital invested.

Someof the tugs carry 5 or 6 miles of nets and catch in one lift from 1,000pounds to 4 or 5 tons of trout. Fishing is done from the time the icebreaks up in the spring until late in the fall or early winter, the work ceasing only when the weather and ice no longer permit operations.In some localities the water becomes so warm during summer as to be detrimental to the nets, and consequently at such points there is a lull in the work for a few weeks. Lake trout spawn on the reefs and live in deep water during the remaining time, and their migratory habits govern the movements of the tugs, the fishermen necessarily moving from one point to a
