Professor Marsh later discovered a similar form in these same fossil beds, and named it _Ceratops montanus_.
The species I discovered were collected on the north side of the river, three miles below Cow Island, after the Professor had taken the last boat down the river. When we uncovered these bones we found them very brittle, as they had been shattered by the uplift of the strata in which they were buried; and we were obliged to devise some means of holding them in place. The only thing we had in camp that could be made into a paste was rice, which we had brought along for food. We boiled quantities of it until it became thick, then, dipping into it flour bags and pieces of cotton cloth and burlap, we used them to strengthen the bones and hold them together. This was the beginning of a long line of experiments, which culminated in the recently adopted method of taking up large fossils by bandaging them with strips of cloth dipped in plaster of Paris, like the bandages in which a modern surgeon encases a broken limb.
I feel it a great privilege to have been one of the original discoverers of these great horned dinosaurs, whose skeletons are now among the chief glories of our museums.
One day, about the fifteenth of October, Professor Cope, who had been anxiously awaiting the arrival of the last steamboat, concluded to ride out on the open prairie to some bad lands which we had seen on our journey down from Dog Creek. I accompanied him. On the way he fell into one of his frequent absent-minded moods, picturing the land as it must have been at the time of the dinosaurs, when the shale of these black-sided canyons was mud on an ocean floor. So fascinated were we both by his descriptions that the time flew by unheeded, and it was afternoon before we reached the prairie south of Cow Island.
Upon arriving at the bit of bad lands, we separated, agreeing to meet at four o’clock at the place where we left the horses. I kept the appointment, but the Professor was nowhere to be seen, and as hour after hour passed with no sign of him, I began to grow anxious. I knew the foolishness of trying to find him in that network of gorges and ridges, and could only wait, eagerly watching the outlets of the labyrinth.
