During windy days the waters imme- diately off shore are clouded with sediment. Fishermen know that at a distance of only a few yards from the shore the lake bottom is almost everywhere covered with clay or sandy clay. The sonndings made by the United States Engineers, who have surveyed the bottom of Lake Erie, show that a muddy bottom is the prevailing feature. When the lake w^aters reached to the height of the gravel ridges, the region below this was naturally a place for the deposit of clay. -"' *.^ '.1 'V ''? ?"?1 ^>i'f-v^*--. 57.—Section through thtt upper beach at Westfield, shovN ing stratiflcatiun of pebbles and sand. While some pebbles may have been drifted away by the ice, and dropped to the bottom away from the shore, the clay was in most places free from large fragments. In some places, particularly opposite the mouths of streams, the clay might be replaced by sand .for a considerable distance from the coast. An examination of the soil between the northernmost gravel ridge and the lake shore, shows that these features exist. A layer of clay, varying in depth from a few inches to several feet, is spread over most of the region west of Silver Creek and north of the gravel ridges. Oftentimes it rests on the bed rock, barely covering it: in other cases it is found above the true boulder clay, and in some stream cuts one may often see a bed of dense boulder clay upon which rests a foot or two of clay, which.
