The latter had embrasures, and the overseer of the works called successively men who, with cords, tied the saucissons and cut the lozenges and right angles of turfs destined to retain the matting of the embrasures. By the activity displayed in these works, already so far advanced, they might be considered as finished: they were not yet furnished with their cannons, but the platforms had their gites and their madriers all prepared; the earth, beaten carefully, was consolidated; and supposing the artillery to be on the island, in less than two or three days the port might be completely armed. That which astonished D'Artagnan, when he turned his eyes from the coast batteries to the fortifications of the city, was to see that Belle-Isle was defended by an entirely new system, of which he had often heard the Comte de la Fere speak as a wonderful advance, but of which he had as yet never seen the application. These fortifications belonged neither to the Dutch method of Marollais, nor to the French method of the Chevalier Antoine de Ville, but to the system of Manesson Mallet, a skillful engineer, who about six or eight years previously had quitted the service of Portugal to enter that of France. The works had this peculiarity, that instead of rising above the earth, as did the ancient ramparts destined to defend a city from escalades, they, on the contrary, sank into it; and what created the height of the walls was the depth of the ditches. It did not take long to make D'Artagnan perceive the superiority of such a system, which gives no advantage to cannon. Besides, as the fosses were lower than, or on a level with, the sea, these fosses could be instantly inundated by means of subterranean sluices.
Otherwise, the works were almost complete, and a group of workmen, receiving orders from a man who appeared to be conductor of the works, were occupied in placing the last stones. A bridge of planks thrown over the fosses for the greater convenience of the maneuvers connected with the barrows, joined the interior to the exterior. With an air of simple curiosity D'Artagnan asked if he might be permitted to cross the bridge, and he was told that no order prevented it. Consequently he crossed the bridge, and advanced towards the group.
This group was superintended by the man whom D'Artagnan had already remarked, and who appeared to be the engineer-in-chief. A plan was lying open before him upon a large stone forming a table, and at some paces from him a crane was in action. This engineer, who by his evident importance first attracted the attention of D'Artagnan, wore a justaucorps, which, from its sumptuousness, was scarcely in harmony with the work he was employed in, that rather necessitated the costume of a master-mason than of a noble. He was a man of immense stature and great square shoulders, and wore a hat covered with feathers. He gesticulated in the most majestic manner, and appeared, for D'Artagnan only saw his back, to be scolding the workmen for their idleness and want of strength.
