The principal operations carried on are the manufacture of lieavy artillery carnages for the sea-coast forts, with aU the requisite implements and equipments ; carnages for siege trains and field batteries, with their equipments and harness ; all machines used in transporting and repau-ing artillery ; ammunition of all kinds for sea-coast, siege, and field guns, and for small arms, and the repair and preseiTatioa of the large quantity of material of war in store. The shops comprise aU requisite facilities for the various mechanics employed, as well as a conveniently arranged and roomy biboratory. The motive power is water, furnished by the Erie Canal. Under ordinary circumstances from 110 to 150 workmen are employed, but, when the exigencies of the service demand it, 500 to 600 can easily be accommodated. The establishment is under the control of a field officer of the ordnance department, assisted by subalterns • of the same, a military storekeeper and paymaster, who is a civilian, and the requisite master, workmen. &c. Forty enlisted Ordnance men are at present stationed at the post, who perform the necessary guard duty and drills, and are at otiier times variously engaged in out-of-door and mechanical employments. The United States have exclusive control of the grounds included within the arsenal enclosure, the State exercising only concm-rent jurisdiction in civil actions and criminal cases."

THE HUDSON.

pleasant mansions and fertile acres are seen on every side. There is a house a mile and a half below the arsenal, scarcely visible from the road because of trees and shrubbery which conceal it, and, when seen, it would not attract special attention, excepting for the extreme plainness and antiquated style of its architecture. A pleasant lane leads to it from the canal, and the margin of the sloping lawn on its river front, over which stately elms cast their shadows, is swept by the Hudson's tide.
