Within a year, Douglass and his men had run a cut over a hundred feet long in the hard sandstone, digging down along the almost perpendicular slant of the rock. At the base of this, rails were laid and small mine carts introduced to haul away the cuttings from the rapidly developing quarry.
New specimens appeared: A small plant-eating dinosaur known as Dryosaurus; an armored form called Stegosaurus; and another large creature like the Apatosaurus. Best of all, the Apatosaurus No. 1 was well on its way out of the rock and would soon be ready to ship to the Carnegie Museum in Pittsburgh.
