Excerpt from Notes on the Quaternary Geology of the Mattawa and Ottawa Valleys Introductory. In the autumn of 1893 the writer made two excursions to North Bay on lake Nipissing, first in August with Dr. F. S. Pearce, of Philadelphia, and again in' Septem ber alone. Two or three days were spent each time searching for old shore lines on the hills or in studying the lower beaches and their relation to the old out-let of the great lakes. The greater part of the time, however, was spent in searching for high beaches. And particularly in an effort to identify the highest. The observations made then were after wards published ih detail.* In 1895 the month of October was spent chiefly in the vi cinity of North Bay and in the Ottawa valley above the city of Ottawa. It is the particular object of the present paper to present the results of this later work. The observations are somewhat scattered, but when taken in connection with what has been done by others and with the writer's work of two years before it is believed that they will not be without value. The paper is presented in two parts, the first relating to the higher, older shore lines, and the second relating to the lower, newer lines, in part lacustrine and associated with the aban doued outlet and in part to those of the contemporary marine waters in the Ottawa valley.
