“Come, merrily now!” ejaculated Courfeyrac. “That’s the brutal part of it. After the fillip on the nose, the blow from the fist. The army is reaching out its big paw to us. The barricade is going to be severely shaken up. The fusillade tries, the cannon takes.”

“It is a piece of eight, new model, brass,” added Combeferre. “Those pieces are liable to burst as soon as the proportion of ten parts of tin to one hundred of brass is exceeded. The excess of tin renders them too tender. Then it comes to pass that they have caves and chambers when looked at from the vent hole. In order to obviate this danger, and to render it possible to force the charge, it may become necessary to return to the process of the fourteenth century, hooping, and to encircle the piece on the outside with a series of unwelded steel bands, from the breech to the trunnions. In the meantime, they remedy this defect as best they may; they manage to discover where the holes are located in the vent of a cannon, by means of a searcher. But there is a better method, with Gribeauval’s movable star.”

“In the sixteenth century,” remarked Bossuet, “they used to rifle cannon.”
