The accompanying illustration, reproduced from the "Plains of the Great West," by the kind permission of the author, is, in one sense, ocular proof that collisions between railway trains and vast herds of buffaloes were so numerous that they formed a proper subject for illustration. In regard to the stoppage of trains and derailment of locomotives by buffaloes, Colonel Dodge makes the following allusion in the private letter already referred to: "There are at least a hundred reliable railroad men now employed on the Atchison, Topeka and Santa Fé Railroad who were witnesses of, and sometimes sufferers from, the wild rushes of buffalo as described on page 121 of my book. I was at the time stationed at Fort Dodge, and I was personally cognizant of several of these 'accidents.'" [Illustration: SLAUGHTER OF BUFFALO ON THE KANSAS PACIFIC RAILROAD. Reproduced from "The Plains of the Great West," by permission of the author, Col. R. I. Dodge.] The following, from the ever pleasing pen of Mr. Catlin, is of decided interest in this connection: "In one instance, near the mouth of White River, we met the most immense herd crossing the Missouri River [in Dakota], and from an imprudence got our boat into imminent danger amongst them, from which we were highly delighted to make our escape. It was in the midst of the 'running season,' and we had heard the 'roaring' (as it is called) of the herd when we were several miles from them. When we came in sight, we were actually terrified at the immense numbers that were streaming down the green hills on one side of the river, and galloping up and over the bluffs on the other. The river was filled, and in parts blackened with their heads and horns, as they were swimming about, following up their objects, and making desperate battle whilst they were swimming. I deemed it imprudent for our canoe to be dodging amongst them, and ran it ashore for a few hours, where we laid, waiting for the opportunity of seeing the river clear, but we waited in vain. Their numbers, however, got somewhat diminished at last, and we pushed off, and successfully made our way amongst them. From the immense numbers that had passed the river at that place, they had torn down the prairie bank of 15 feet in height, so as to form a sort of road or landing place, where they all in succession clambered up. Many in their turmoil had been wafted below this landing, and unable to regain it against the swiftness of the current, had fastened themselves along in crowds, hugging close to the high bank under which they were standing. As we were drifting by these, and supposing ourselves out of danger, I drew up my rifle and shot one of them in the head, which tumbled into the water, and brought with him a hundred others, which plunged in, and in a moment were swimming about our canoe, and placing it in great danger. No attack was made upon us, and in the confusion the poor beasts knew not, perhaps, the enemy that
