The compiler thinks it necessary to address himself to two classes of persons in particular; perhaps they may comprise the whole of his readers. First, those who think his little book might have been made much more complete. Second, those who think it improper that any information upon such matters should be offered to the public. To the first, he acknowledges the justice of the remark, but has to remind them, of the very great difficulties which they may themselves have experienced, in collecting information at Woolwich. To the second, he has but to remark, that he is well aware of the objections urged against publications which may give information as well to our enemies as our friends; but he does not imagine his little book to contain matter of sufficient consequence to do such mischief: and he is supported in an opinion by the most powerful and best organized military nations in Europe, that such secresy is the surest mark of ignorance. The first edition being out of print, the compiler has endeavored to improve this, by _every_ correction, and by _some_ of the additions which his friends have been kind enough to suggest to him as necessary: but if he has neglected much of the valuable information offered him, it has not been from an insensibility of its merit, but from its entering more into the detail of matters than his little book would afford room to profit by; for it still professes not to instruct, but only to remind. The compiler has added to this edition a short alphabetical index to the contents. This may appear to some superfluous, considering the alphabetical arrangement of the subjects: but it has been impossible to avoid a great deal of reference from one part of the work to another: beside, the compiler has observed in several of the copies in the possession of his friends, notes in manuscript, (entered on sheets bound up for the purpose) which are also to be found in the body of the work. This the compiler attributes to a cause which the index may probably remedy, by enabling the reader to know, at one view, the whole contents. _AMMUNITION_—For small arms, in the British service, is generally packed in half barrels, each containing 1000 musquet, or 1500 carbine cartridges. An ammunition waggon will carry 20 of these barrels, and an ammunition cart 12 of them: their weight nearly 1 cwt. each. The cartouch boxes of the infantry are made of so many different shapes and sizes, that it is impossible to say exactly what ammunition they will contain; but most of them can carry 60 rounds. See the word _Cartridges_; and for Artillery Ammunition, see the word _Artillery_, for the field, for the siege, and the defence of a fortified place. The French pack all their ammunition in wagons without either boxes or barrels, by means of partitions of wood. Their 12 Pr. and 8 Pr. waggons will contain each 14,000 musquet cartridges, but their 4 Pr. waggons will contain only 12,000 each. _AMMUZETTE_—See the word _Guns_.
