The clay might be serviceable for sewer pipe,but for this purpose is not as desirable as the material located onMilk Creek. It is not a fire clay. Pressed brick could probablyalso be made from it.

In most of the cuts the shale beds are lenticular, andrarely over a few feet in thickness, but if they were refractory itwould be possible to work them as narrow cuts. With this inmind, samples were taken from the most promising lookingexposures but none of the samples proved to be fire clays. Allwere red-burning. The best exposure observed was a dark shaleon the bank of the Old Man River, one mile west of width of the outcrop is over fifty feet and there is no over-burden. This shale may be suitable for pav
