OBITUARY. GEN. JOHN S. CROCKER. Gen John S. Crocker, Warden of the District of Columbia Jail, died at his residence in Wash- inton yesterday. He was about seventy years of age. He was in good health when he arose in the morning, but at about 3 o'clock he was seized with a hemorrhage and died before a doctor arrived. He was a native of New-York State. At twen- ty-one years of age he began the practice of the law at Cambridge, Washington County, N.Y. He served in the State Legislature, and was a friend of Gov. Morgan. When the war broke out he organized a regiment, which he named the Morgan Rifles, its official designation being the Ninety-third New-York. He entered the Union service as Colonel. The regiment was assigned to the Army of the Potomac, and was the head- quarters guard of that army under McClellan, Hooker Meade and Burnside. Gen. Crocker was captured in 1862, but after confinement in Libby, Salisbury, N.C., and Belle Isle prisons, was by special arrangement of Secretary Stan- ton exchanged for Col. Chancellor of the Con- federate Army. He took part in every battle of the army of the Potomac, and was wounded three times at the Wilderness, and also at Spots- ylvania Court House. fter the battle ofSpots- ylvania he became Brigadier General, succeed- ing Gen. Hayes. After the war he went to Washington, where he had since lived. He was President of the old Board of Aldermen when appointed Warden of the District Jail in 1869. He had held the office ever since, and was proud of the fact that he had been longer in this position than any man in this country holding a similar office. He was Warden of the jail during the Guiteau excite- ment, and had charge of all the arrangements for the confinement and hanging. He was a Mason.
