The decrease in numbers of bluebacks was synchronous with the increase in number of salmon, and coincidently the last blueback was taken in the year following the largest catch of salmon up to that date. There can be no doubt that the blueback entered largely into the food of the salmon, especially prior to the introduction of the smelt, living as it did in the deep waters to which salmon resorted during the summer months, and the introduction of smelt and later legislative action were both

There can be no doubt that the blueback entered largely into the food of the salmon, especially prior to the introduction of the smelt, living as it did in the deep waters to which salmon resorted during the summer months, and the introduction of smelt and later legislative action were both too late to save it. On the other hand, the large size of the few surviving bluebacks was very probably due to the smelt. Although the food of the blueback was formerly the smaller animal life of the lake, probably largely consisting of entomostracans, insect larvae, and worms, the smelt afforded it an abundant additional supply of food, owing to the fact that while almost in a larval stage young smelts frequent deep water after leaving their birthplaces in the brooks.

To the fish culturists this char is known as the golden trout or aureolus and some- times as Sunapee trout or Sunapee Lake trout, these latter names due to its having been first discovered in Sunapee Lake, N. H. The name golden trout is derived from its. Fio. 18.—White trout {Salvditms aureolus). technical name, aureolus, which was g^ven to it in reference to the golden sheen of the living fish in the water. The local name, white trout, is more appropriate to its summer coloration, when the brilliant orange of the males is absent. It is known as white trout at Sunapee Lake and is thus distinguished from the common trout (Salvelinus fontinalis) which at Sunapee Lake is called native trout, due to the popular impression, doubtless, that the white trout was introduced. About the time the fish was discovered at Sunapee Lake there was an animated di
