Science. 14 ANNALS NEW YORK ACADEMY OF SCIENCES absence in the other, the effect of these things upon the activities of the people—all of these topics are readily illustrated in our immediate area. In Bronx Park glacial stria;, roches moutonnees, and erratics are under our feet at every step. The "Rocking Stone Restaurant" takes its name from a near-by erratic (Fig. 9). The drumlins of the Boston Bay region and the great swarm of western New York (Fig. 10), the eskers of south- ern Maine and an occasional one in New Jersey, the sand plains of New England, the kame hills scattered over New York and New Jersey, are topics of interest. There is also the subject of marginal lakes illustrated by Lake Passaic in New Jersey, Lake Bascom in the Berkshire region, and Lake Iroquois in New York.

Boulder-cov- ered fields in southern Pennsylvania, Maryland, and Virginia are not known. The aspect of the country is different and this difference is re- flected in the industries and economic development of the region. Waves.—The subject of wave work is no less limited in the prolificacy of examples available. The development of the features upon an emerged shoreline is illustrated in the unrivaled offshore bars and lagoons of the Long Island and New Jersey coast, both typically in the youthful stage, though it may be held that in northern New Jersey where the bar has been pushed back agai
