The plot, dextrous as the contrivance of it had been, was not destined to succeed. The vessel moved gently from the shore, rowed by the mariners. It was a clear starlight night. The sea was smooth, and the air was calm. Agrippina took her place upon a couch which had been arranged for her, under a sort of canopy or awning, the frame-work of which, above, had been secretly loaded with lead. She was attended here by one of her ladies named Aceronia Polla, who lay at her mistress's feet, and entertained her with conversation as the boat glided along on its way. They talked of Nero--of the kind attentions which he had been paying to Agrippina, and of the various advantages which were to follow from the reconciliation which had been so happily effected. In this manner the hours passed away, and the barge went on until it reached the place which had been determined upon for breaking it down and casting Agrippina into the sea. The spot which had been chosen was so near the land as to allow of the escape of the mariners by swimming, but yet remote enough, as was supposed, to make Agrippina's destruction sure. A few of the mariners were in the secret, and were in some degree prepared for what was to come. Others knew nothing, and were expected to save themselves as they best could, when they should find themselves cast into the sea. At a given signal the fastenings of the canopy were loosened, and the loaded structure came down suddenly with a heavy crash, carrying away with it other parts of the vessel. One man was crushed under the weight of the falling ruins, and instantly killed. Agrippina and the lady in waiting upon her were saved by the posts of the bed or couch on which Agrippina was reclining, which happened to be in such a position that they held up the impending mass sufficiently to allow the ladies to creep out from beneath it. The breaking down, too, of the deck and bulwarks of the barge was less extensive than had been intended, so that Agrippina not only escaped being crushed by the ruins but she also saved herself at first from being thrown into the sea. The men then who were in the secret of the plot immediately raised a great cry and confusion, and attempted to upset the barge by climbing up upon one side of it--while the others, who did not understand the case, did all they could to save it. In the mean time the noise of the outcries reached the shore, and fishermen's boats began to put off with a view of coming to the rescue of the distressed vessel. Before they arrived, however, the boat had been overturned, Agrippina and Aceronia had been thrown into the sea, and the men who were in the secret of the plot, taking advantage of the darkness and confusion, were endeavoring to seal the fate of their victims, by beating them down with poles and oars as they struggled in the water.
