The flour and biscuit which are taken out to sea in the British navy are packed in casks of wrought-iron. These were formerly painted, to prevent rust, and also to make them water-tight; but the paint was found to give a bad taste to the flour, &c., and they are now coated outside with a waterproof composition of caoutchouc, black resin, and Venice turpentine.
