There is, however, one discovery, made since the date of these above recorded, of human work below the great basalt cap of North-Western America, brought up from a great depth of underlying gravels and sands of a silted-up lake, formerly forming part of the course of the Snake river at Nampa in Idaho, which is as startling in its way as that of the Calaveras skull. The following account of it is given on the authority of Professor Wright, who, having visited the locality in the summer of 1890, states that he found "abundant confirmatory evidence"-- The Nampa image was brought up in boring an Artesian well, at Nampa in Ada county, Idaho, through a lava-cap 15 feet thick, and below it about 200 feet of the quicksands and clays of a silted-up lake, formed in a basin of the Snake river, which joins the Columbia river, and flows into the Pacific, forming part, therefore, of the same geographical and drainage system as the Californian gravels. At this depth the borers came down to a stratum of coarse sand, mixed with clay balls at the top, and resting at the bottom on an ancient vegetable soil, and the image came up from the lower part of this coarse sand. The borer, or liner of the well, was a six-inch iron tube, and the drill was only used in piercing the lava, while the sands below it were all extracted by a sand pump. Mr. King, a respectable citizen of Nampa, who was boring the well, states that he had been for several days closely watching the progress of the well and passing through his hands the contents of the sand pump as they were brought up, so that he had hold of the image before he suspected what it was. Mr. Cumming, superintendent of that portion of the Union Pacific Railway, a highly-trained graduate of Harvard College, was on the ground next day and saw the image, and heard Mr. King's account of the discovery, and Mr. Adams, the president of the railway, happening to pass that way about a month later, he brought it to the notice of some of the foremost geologists in the United States. The image was sent to Boston by Mr. King, who gave every information, and it was found to be modelled from stiff clay, like that of the clay balls found in the sand, slightly if at all touched by fire, and incrusted like those balls with grains of oxide of iron, which Professor Putnam considers to be a conclusive proof of its great antiquity. Mr. Emmons, of the State Geological Society, gives it as his opinion that the strata in which this image is said to have been found, is older by far than any others in which human remains have been discovered, unless it be those under Table Mountain, in California, from which came the celebrated Calaveras skull. So much for the authenticity of the discovery, which seems unassailable, but now comes the remarkable feature of it, which to a great extent revolutionizes our conception of this early palæolithic age. The image, or rather statuette, which is scarcely an inch and
