At the quarry, excavating continued summer and winter. The methods employed were those that paleontologists had used for decades. There was no compressed air, no labor-saving devices. The work was done by hand. The crew, which seldom exceeded four men at any one time, became veterans in the art of fossil extraction. The bone was brittle; the encasing sandstone, hard. It required toil, patient direction, and a knowledge of anatomy. Judiciously placed charges of giant powder shattered the overburden. Hand drills, wedge-and-feather, and crowbar worked the rock away, until the bone layer was encountered. The slow attrition by hammer and chisel accomplished the final delicate separation of the remains from the enclosing matrix. Team-and-scraper and small handcarts removed the rubble that swiftly accumulated in the cut. As the bones were chiseled from the quarry face in large blocks of rock, they were encased in strips of burlap dipped in flour paste. (Later, plaster of Paris supplanted the flour paste.) Then they were lowered by rope onto a mule-drawn skid and “snaked” down the trail into the gulch to await boxing.

COGGESHALL.)] Transporting the fossils from quarry to railhead was a major undertaking. It required wagon trains—4-horse teams hauling high-wheeled freight wagons over 60 miles of rutted roads to Dragon, Utah. There the precious goods were loaded onto boxcars of the now abandoned narrow gauge Uintah Railway, later to be transhipped to the standard gauge Denver & Rio Grande line at Mack, Colo. FURTHER DEVELOPMENT Specimens continued to show in record abundance, most of them duplicating the earlier finds of _Diplodocus_ and _Stegosaurus_. But there were new forms, too. One of them was a _Camptosaurus_, the first to be found at the quarry. It was a modified biped of plant-eating habits, a little more than 10 feet long, with its skull and part of the tail missing. By 1921 the deposit had been worked to a length of 400 feet east and west, and to a depth of about 60 feet. Rock was being stripped from the quarry face at the rate of approximately 20,000 cubic feet annually, and the chisels of Douglass and his men had penetrated to the richest bone-bearing zone. In the following year they uncovered one of the most perfect skeletons of a dinosaur ever exhumed. It was a small sauropod named, _Camarasaurus lentus_. When found, its 17-foot vertebral column was practically intact, except for a few tail segments. The skull was in place, and the limbs in their approximate positions.
