Filled cannoncartridges forSteamers, stowedin Dell’s metalcases.

Filled cannoncartridges forLand Service,stowed in ammu-nition boxes.

A whole case will stow 110 lbs. of powder in cartridges,—the half and quartercases in proportion. Besides the cannon cartridges, all the small-arm ammunitionand other combustible stores for Sea Service, such as blue lights, long lights,portfires, &c., &e., are packed in these different copper-lined cases. They aremanufactured in the Royal Carriage Department, are very durable, and capable ofstanding much hard service, and generally repairable. The cost of a whole case is£1. 14s. lOrf.

All filled cartridges for II. M. steamers are stowed in ‘ Dell’s metal cases,’ themouth of which is similarly secured, and the lid marked with its contents, in colours,as on wood copper-lined cases. They are of hexagonal form; the number of filledcartridges they will contain is the same as the wooden cases, and, like them, they arealso divided into whole, half, and quarter cases. There are also sectional cases, forthe top tier, bottom, and sides.

The following is a representation of the mode of stowing the different metal casesin the magazines of H. M. steamers.

Dell’s cases are composed of a combination of metals, chiefly tin and copper. Theyare obtained by contract from the patentee at the price of Is. 2 d. per lb., or about£ 2. 18s. id. for a whole case. With fair usage and wear and tear, they are generallydurable, and in most instances are repairable after long service at sea. They areconsidered to be best adapted for steamers, on account of economy in space.

Note .—All boat ammunition for steamers is stowed in metal-lined cases, the sameas for sailing vessels.

Filled cannon cartridges for Land Service are kept in the magazines, stowed inammunition boxes. These cartridges are, however, generally limited in number,according to circumstances.
