282 A course by Mr. Grabau on the use of the microscope and the preparation of specimens was followed by ten days' laboratory work in Limekilns Bay, Maine. One of the results of a winter course on zoölogy, to a class of twenty teachers, was the formation of the Hale House Natural History Club, in connection with which field meetings are held, classes for children are formed, and papers upon elementary subjects are read and discussed. Other courses of lectures are mentioned in the report of the curator of the society—the field lessons in geology, by Professor Barton, with a winter course in historical geology; the course of Dr. R. W. Greenleaf, on the elementary structure and function of the parts of flowering plants; the course of the curator (Alpheus Hyatt), on elementary zoölogy; and the lectures on geography, by Prof. W. M. Davis.

Glacier Water.—An analysis of two samples of water from the Illecilliwaet Glacier, in British Columbia, was recently made by F. T. Shutt and A. T. Charron. The water was collected a few feet from the glacier's irregular face, about a mile and a half from the glacier station on the Canadian Pacific Railway. The following is abstracted from an account in the Chemical News:

The authors go on to say: "From the above data we may unhesitatingly conclude that the glacier water is one of great organic purity. The samples are not identical, due no doubt to the fact that they were collected twelve days apart, and probably from different parts of the foot of the glacier. Both analyses, however, show that, judged by the standards used in the diagnosis of ordinary potable waters, it is a water possessing a high degree of purity, and one perfectly wholesome and eminently suited for drinking and household purposes. As received, both samples were quite murky, almost milky, in appearance. On allowing them to stand, perfect subsidence took place, leaving the supernatant water colorless and brilliant. A microscopic examination of the sediment showed it to consist of very fine rock matter, chiefly fragments of quartzite.

Protection of Plants and Birds in France and Italy.—Organized efforts for the protection of native plants and birds from further destruction are multiplying in Europe. Botanical stations for Alpine plants have been established at several places in France and Switzerland, and now Italy has come into line with the association Pro Mortibus, which, founded in July, 1897, has already more than five hundred adherents. Italy is probably the country where work of this kind is most needed, for nowhere else is the destruction, particularly of birds, so systematically, persistently, and industriously carried on. Pro Mortibus will also interest itself in the preservation and replantation of the forests. Among other efforts looking in a similar direction, M. J. Corcelli tells in La Nature of the establishment of shelters in connection with the schools in Saxony where birds are fed in the winter, and of lessons given to the children inculcating regard for them. A great deal has been accomplished in France without much noise in rewooding the devastated slopes of the mountains and erecting efficient safeguards against ravage by torrents—largely by restraining the torrents at their sources; and the Alpine forests of the country, M. Corcelli says, "are again rising from their ashes." Reserves of Alpine plants have been established by the Belfort section of the French Alpine Club on the Ballon of Alsace; the central section is creating an extensive botanical garden in the Vosges, to serve as a place of refuge and propagation and multiplication of species threatened with extinction. The city of Annecy, in Savoy, has recently voted the money required
