the Rough Riders, doubtless because the bulk of the men were from the Southwestern ranch country and were skilled in the wild horsemanship of the great plains. Wood instantly began the work of raising the regiment. He first assembled several old non-commissioned officers of experience, put them in office, and gave them blanks for requisitions for the full equipment of a cavalry regiment. He selected San Antonio as the gathering-place, as it was in a good horse country, near the Gulf from some port on which we would have to embark, and near an old arsenal and an old army post from which we got a good deal of stuff--some of it practically condemned, but which we found serviceable at a pinch, and much better than nothing. He organized a horse board in Texas, and began purchasing all horses that were not too big and were sound. A day or two after he was commissioned he wrote out in the office of the Secretary of War, under his authority, telegrams to the Governors of Arizona, New Mexico, Oklahoma, and Indian Territory, in substance as follows: The President desires to raise --- volunteers in your Territory to form part of a regiment of mounted riflemen to be commanded by Leonard Wood, Colonel; Theodore Roosevelt, Lieutenant-Colonel. He desires that the men selected should be young, sound, good shots and good riders, and that you expedite by all means in your power the enrollment of these men. (Signed) R. A. ALGER, Secretary of War. As soon as he had attended to a few more odds and ends he left Washington, and the day after his arrival in San Antonio the troops began to arrive.
