returned with flashing eye, and trembling with rage, to the side of his wife, with whom he appeared for some minutes to hold counsel, after which they flew away into the air, and quickly disappeared. The female sparrow came back soon after; the male recounted all that had passed--the arrival, the attack, and flight of the swallows--not without accompanying the recital with what seemed to Cuvier to be roars of laughter. Be this as it may, the housekeeper did not rest satisfied with making only a hullah-balloo, for the female went forth again, and collected in haste a much larger quantity of provisions than usual. As soon as she returned, after having completed the supplies for a siege, two pointed beaks, instead of one, defended the entrance to the nest. Cries, however, began to fill the air, and an assemblage of swallows gathered together on a neighboring roof. Cuvier recognized distinctly the dispossessed couple, who related to each newcomer the impudent robbery of the sparrow. The male, with blood-stained head and bared neck, distinguished himself by the earnestness of his protestations and appeals of vengeance. In a little while two hundred swallows had arrived at the scene of conflict. While the little army was forming and deliberating, all at once a cry of distress came from an adjacent window. A young swallow, doubtless inexperienced, instead of taking part in the counsels of his brethren, was chasing some flies which were buzzing about a bunch of neglected or castaway flowers before the window. The pupils of Cuvier had stretched a net there to catch sparrows; one of the claws of the swallow was caught by the perfidious net. At the cry which this hair-brained swallow made, a score of his brethren flew to the rescue: but all their efforts were in vain; the desperate struggles which the prisoner made to free himself from the fatal trap only drew the ends tighter, and confined his foot more firmly. Suddenly a detachment took wing, and, retiring about a hundred paces, returned rapidly, and, one by one, gave a peck at the snare, which each time, owing to the determined manner of the attack, received a sharp twitch. Not one of the swallows missed its aim, so that, after half an hour of this persevering and ingenious labor, the chafed string broke, and the captive; rescued from the snare, went joyously to mingle with his companions. Throughout this scene, which took place twenty feet from Cuvier, and at almost as many from the usurped nest, the observer kept perfectly still, and the sparrows made not the slightest movement with their two large beaks, which, formidable and threatening, kept its narrow entrance. The council of swallows, while a certain number of them were succoring their companion, had continued to deliberate gravely. As soon as all were united, the liberated prisoner included, they took flight, and Cuvier felt convinced they had given up the field, or rather the nest, to the robbers, who had so fraudulently possessed themselves
