Annual report of the United States Geological Survey to the Secretary of the Interior . ng up the bay, at a point a fewhundred yards southwest of McNeil Canyon, Mr. Curtis has run twoshort tunnels into the bluff about 45 feet above the beach. The clearcoal is here 4 feet 7 inches thick, with about 6 inches of iron-stainedsandstone above it and a thick, adhesive, gray clay below. This seamwould require timbering, to avoid caving in, if worked to any this are three other seams, separated by thick beds of clay orsoft sandstone. One of these, the lower seam, is nearly 4 feet thick;the others are somewhat thinner. The strata are here nearly hori-zontal. The coal, though lighter than the Bradley, is fairly compact,with a dull fracture, no visible pyrite, occasional thin lenses of sandor shale, and a tendency to break up cubically. This will be referredto as the Curtis seam. mneil CANYON. From McNeil Canyon, next above, in 1891, Lieut. B. P. Sehwerin,U. S. N, on behalf of New York parties, prospected for coal, and took lPl. LII gives a general view of these KENAI PENINSULA. 703 out 200 tons of it, which was taken to San Francisco and in Septem-ber, 1891, was submitted to a series of tests which will be referred tolater. This expedition left no permanent works or buildings. The next locality is the Cottonwood Canyon, where some prospectinghas been done and a log house built at the delta as a shelter for theprospectors and to hold the location. The exploration here has notproceeded far. EASTLAND CANYON. Next above is Eastland Canyon, where more work has been done thanat any other single locality on the bay. The engineer in charge, B. Curtis, offered us every hospitality in his power, and showed useverything which was to be seen. A small tramway leads back several hundred yards into the canyon,and at a height of 270 feet above the tide we found a vein 2 feet 4 inchesthick of clear coal, and associated with it alternate smaller seams of coaland clay
