DUTIES OF THE INSPECTOR OF ORDNANCE.—LIST
OF ARTICLES IN OUTFIT, WEIGHTS AND
STOWAGE SPACE.

DUTIES OF THE INSPECTOR OF ORDNANCE AT THE NAVY
YARD IN CONNECTION WITH THE TORPEDO
OUTFIT OF A SHIP.

GUN-COTTON MAGAZINE.

He will carefully inspect the gun-cotton magazine, satisfy himself that it is constructed in accordance with the Ordnance Instructions concerning shell-rooms, and the directions given on pages 40 and 41 Spar-Torpedo Instructions, that it is of sufficient size to stow the portion of the torpedo outfit defined in the “Table showing Weight, Space and Place of Stowage of Articles in Spar-Torpedo Outfit” and will prepare a plan of stowage.

TORPEDO STOREROOM.

He will carefully inspect the torpedo store-room, satisfy himself that it is in a proper position with regard to battery and boilers, that it is not exposed to undue changes of temperature, or to accidental admission of water, and that it is of sufficient capacity and conveniently arranged to stow the portion of the outfit defined in “Table showing Weight, Space and Place of Stowage of Articles in Spar-Torpedo Outfit.”

BATTERY LOCKER.

He will carefully inspect the battery locker and see that it is in a proper position with regard to the great-gun battery and the boilers. It should, preferably, be in a good light.

SHIP‘S SPARS AND FITTINGS.

He will, while the ship‘s spars and fittings are being made and when they are in place, inspect them carefully, satisfy himself that the spar-bands are properly spaced and in line to receive the secondary spar and report to the Bureau the position and class of the heel fittings and the leads of topping-lifts and guys, with his opinion of their efficiency and convenience.

PERMANENT WIRES.

He will ascertain what firing apparatus the Bureau intends to place on board and make a requisition for the necessary wire and terminals.

Upon the receipt of these articles he will locate the firing apparatus and prepare and place the permanent wires and terminals.

He will cause a plan showing the lead of the different wires to be made, and will send copies to the Bureau and to the Torpedo Station, and will furnish one to the commanding officer of the vessel.

No fixed rules can be given for leading permanent wires. The general method of leading the upper-deck wires, manner of securing to terminals and precautions to be observed, are given on pages 14 and 15. Permanent wires should also be led from the battery to the firing-point on the bridge or elsewhere. In case of electrical gun-circuits being desired, special directions or plans will be issued by the Bureau of Ordnance.
