a restored skeleton. It was seen from the first that the take of recovering such a large skeleton fromt he sandstone ledge, even if it lay in favorable position, would be slow, difficult, and expensive but Mr. Carnegie had been personally consulted concerning the matter and the orders form the direcotr were to go ahead with the work. The sandstone containing the bones, with the other formations in this region, had been upheaved into a large wave like uplift while the crest of the great wave had been worn off by erosion. Had there been no upheavel or erosion one might have walked over the surface of the plain in utter ignorance of the remains of strange beasts lying three miles or more beneath his feet.
