Many advantages are gained by this opera-tion, first, the cake when made into grain of the re-quired size absorbs less moisture from the atmo-sphere than if it had been soft and not pressed, andthe lasting qualities of the powder are much in-creased, especially if glazed; again, by having beencompressed the powder is less liable to be reducedto dust in transport, for if proix-rly made it maysafely be kept for a number of years, even on boardship at sea, without any appreciable , by a closer connection of the ingredients alarger volume of gas is proiluced. bulk for bulk, thanfrom a soft light powder; it also produces more. grain than could be obtained from • mill cake notpressed, ami consequently there is less waste by dustin manufacture, and in addition to this, a hard,clean-grained powder does not foul the gun so muchas a soft powder. For the purpose of compressing the meal powderinto what is called press cake, a powerful hyilrau-lic press is employed. The apparatus for holdingthe meal consists of a very strong gun-metal boxincased on the outer and inner sides with oak; it is POWDER-PKOOF. 574 POWER OF ATTORNEY. 2 square and 2 6 deep, the bottom and one sideare permanently fixed to each other, but the otherthree sides are hinged to the bottom, so as to allowof their being opened; when shut these sides arefirmly held together by strong,coarse-threaded metalscrews.
