In giving an impulse to the interior labours of the _Dépôt_, the sole object of General A----y is to make this establishment lose its _paralyzing_ destination of archives, in which, from time to time, literati might come to collect information concerning some periods of national or foreign history. He is of opinion that these materials ought to be drawn from oblivion, and brought into action by those very persons who, having the experience of war, are better enabled than any others to arrange its elements. Instruction and method being the foundations of a good administration, of the application of an art and of a science, as well as of their improvement, he has conceived the idea of uniting in a classical work the exposition of the knowledge necessary for the direction of the _Dépôt_, for geographical engineers, staff-officers, military men in general, and historians. This, then, is the object of the _Mémomorial du Dépôt de la guerre_, a periodical work, now in hand, which will become the guide of every establishment of this nature[6], by directing with method the various labours used in the application of mathematical and physical sciences to topography, and to that art which, of all others, has the greatest influence on the destiny of empires: I mean the art military. The improvements of which it is still susceptible will be pointed out in the _Mémorial_, and every new idea proposed on the subject will there be critically investigated. In transcribing General A----y's sketch of this extremely-interesting establishment, I cannot but reflect on the striking contrast that it presents, in point of geographical riches, even half a century ago, to the disgraceful poverty, in that line, which, about the same period, prevailed in England, and was severely felt in the planning of our military expeditions. I remember to have been told by the late Lord Howe, that, when he was captain of the Magnanime at Plymouth, and was sent for express to London, in the year 1757, in order to command the naval part of an expedition to the coast of France, George II, and the whole cabinet council, seemed very much astonished at his requiring the production of a map of that part of the enemy's coast against which the expedition was intended. Neither in the apartment where the council sat, nor in any adjoining one, was any such document; even in the Admiralty-office no other than an indifferent map of the coast could be found: as for the adjacent country, it was so little known in England, that, when the British troops landed, their commander was ignorant of the distance of the neighbouring villages. Of late years, indeed, we have ordered these matters better; but, to judge from circumstances, it should seem that we are still extremely deficient in geographical and topographical knowledge; though we are not quite so ill informed as in the time of a certain duke, who, when First Lord of the Treasury, asked in what part of Germany was the Ohio?
