In the deeper pits from which brick clay is being taken (as at Haggerty’s. Daniel’s and Clippert’s). three quite distinct beds may be noted, distinguished by their color and rather sharply separated. Beneath from 6 to 12 inches of surface soil, there occurs a yellowish-brown layer from 2 feet to 4 1/2 feet in thickness. Beneath this occurs a layer in which the iron ingredient has assumed a slight reddish tinge, ranging in thickness from 3 to 5 feet, giving out to the eastward, or becoming indistinguishable from the upper. Below this lies a bluish bed, extending apparently to the bottom of the deposit. It is conceivable that these three beds were formed under slightly varying conditions during the lifetime of a single glacial lake, or that they represent the deposits of three successive lakes such as the Lundy, Warren and Wayne. Somewhat confirmatory of this latter view is the fact that there is an average increase in the amount of sand towards the top as though the water was becoming shallower during deposition and the shore line had drawn nearer to the region. The following analyses of these clays were made for this report in 1902 by Elmer E. Ware, under the direction of Prof. E. D. Campbell of the University of Michigan.
