. Annual report of the Regents. New York State Museum; Science. REPOKT OF THE DIRECTOR rl41 The sketch of a cross section of such a cliff shows these features: The drift covered ruck with a perpendicular front and a gradual slope beneath the water covered with material from the shore, and the shingle-strewn beach protecting the base of the cliff. See fig. 4. Section oj^a wave cut At several points the cliff is interrupted by banks of drift. On examining such a bank it is noticed that the rock ends and the gravel begins abruptly. The small runlets coming into the lake over such an area of drift may have cut down to considerable depth, but they do not reach the bed rock. The gravel itself is entirely without stratification, and the pebbles striated and of a heterogeneous character. It is evident that these are preglacial stream courses, completely choked by drift. An excellent example is seen about mid-way between Ludlowville and the south end of the lake. So much for tlie geology and topography of this region. Let us now investigate the historical side of the problem. What is the origin of Cayuga lake ?.
