The observations which he has recorded were made in the course of a preliminary investigation of these lakes by the United States Fish Commission, and constitute the only information on record with reference to the lakes of the country west of the Missouri River. There are only two localities which may be listed, however, as individual resorts sufliciently regularly visited to entitle them to more particular mention in this place. Green Lake, in Wisconsin, has been carefully studied by Professor Marsh, of Ripon College, and his work has yielded valuable information with reference to the vertical distribution of the crustacea and with regard to the deep-water fauna of the lake. Here he was able to confirm the observation of Stimpson on Lake Michigan, that there are found in the deep waters of our large lakes crutacea of a purely marine type. At Lake Mendota in Wisconsin, on the shores of which are located the State University, a careful investigation extending over a very considerable number of years has been carried on by Professor Birge of the University. The results which he has obtained with reference to distribution, both vertical and seasonal, have been published by the Wisconsin Academy, and are not only the most extensive, but beyond all comparison the most precise investigations which have been made on this problem. Of course, in one sense, this station has no building, but the scientific laboratory of the University, standing within a stone's throw of the shore of the lake, affords opportunities which are not surpassed at any fresh-water station in the world.
