The excellent discipline of this institution is due, in the main, to Captain Bradbury, the deputy warden. He is beyond doubt, one of the best, and most experienced prison men in the United States. He has been connected with the Missouri prison for thirty-three years. The warden looks after the finances of the institution, and it belongs to Captain Bradbury to hold in subjection the two thousand criminals that are crowded together in that small prison enclosure. This celebrated deputy warden is a Virginian by birth. He is sixty-two years of age. He served in the Mexican war, and now draws a pension from the Government, because of his services there. If a prisoner conducts himself properly, Captain Bradbury will treat him as humanely as he can under the circumstances. If he becomes willful and unruly, the Captain no doubt will take great pleasure in giving the offender "a good paddling," to use his own forcible expression. This official is a strong advocate of corporal punishment. He claims that a "little loosening up of the hide" of an obstreperous prisoner does the said prisoner a vast amount of good. Among the convicts the deputy warden is austere. He is never seen sauntering about the prison enclosure with his long arms entwined about any of "the boys in stripes." He claims, that too great a familiarity breeds contempt. This seeming harshness when in the presence of the prisoners is only borrowed for the occasion, for, away from the convicts, there is not a more social gentleman in the State of Missouri. Great credit is due to Captain Bradbury for his excellent management of this institution, under such unfavorable circumstances. Could he be persuaded to quit the use of the whipping post, and use other measures less barbarous, I think the same discipline could be secured, as now exists. The officers here do not seem to be so exacting as in many other prisons. In the Kansas penitentiary, when prisoners are in ranks going to and from their meals, their cells, or workshops, they are required to fold their arms, and keep their eyes fixed upon the back of the one's head just in front. No gazing about is permitted, and should a prisoner speak to one in the front of him and be detected, he would be summarily dealt with. In the Missouri prison I noticed that the convicts while marching would gaze about wherever they wished, and go swinging along with their arms dangling at their sides. In many prisons the inmates are required, while in ranks, to keep their hands on the shoulders of the man in front. This would seem to be the most desirable way of having the prisoners march. In this prison one can detect more of a homelike feeling, not so rigorous and exacting as in many institutions of this nature. Captain Todd, assistant deputy warden, is another official of long standing. He has been with this prison for eighteen years, and is very popular. In this connection we must not fail to mention Captain
