The cry of Juan was perhaps not heard by his fellow-Christians in the brigantine; but there was one friend aboard, and that a brute one, whose ears were far quicker to detect his call, and whose heart was much prompter to obey. This was the dog Befo, who, having been taken from the prison on the day of the trial, and afterwards been refused admission, he so annoyed the guards by his whining and howling, and indeed all in the palace, likewise, that they were glad to send him aboard a vessel, to have him out of the way, until after the time of execution, when, it was apprehended, from his remarkable affection for the prisoner, he might give additional trouble. His services were turned to good account by the sailors, during the attack; for, being instantly loosed, he sprang upon barbarian after barbarian, tumbling them into the water, or among the Spaniards, who despatched them. His appearance, fiercer than that of the largest beasts of prey in Mexico, and his savage bark, not less frightful than the yell of the jaguar or the puma, were perhaps still more effectual than his fangs; for at the sight and sound, the Mexicans, climbing over the bulwarks, recoiled, and with screams of dismay, jumped into the water, and swam again to the nearest canoes. In the midst of the conflict, Befo heard the cry of his master, and loosing a barbarian whom he had caught by the throat, he sprang to the side of the vessel, thrust his paws and nose over the gunwale, and looked eagerly into the lake, whining all the time, and barking, as if to attract Juan's notice. He then ran to the after-deck, where were several sailors busily engaged in knotting a rope that seemed to pass to the shore, or to another brigantine nearer to the lake-side; and flinging himself over the railing here as before, he looked out and whined loudly again. As he peered thus into the darkness, a faint groan, as of one strangling in the water, came to his cars; and the next moment, he sprang, with a wild howl, into the flood. That groan came from Juan Lerma, who, that instant, was struck a violent blow, he knew not by whom or with what, which, for a time, deprived him of all sensation, and left him drowning in the lake. CHAPTER III. When Juan recovered his senses, he found himself lying in the bottom of a little canoe, urged by a single boatman, and already far from the conflict. The blow, inflicted by some blunt weapon, perhaps a club or paddle, had stunned him, yet had not wounded; and he became soon aware that he was not seriously injured. As he raised himself a little on his arm, his companion, pausing an instant from his toil, exclaimed, in the well remembered tones of the Ottomi, "Izquauhtzin knows his friend: there are none to do him harm." "Techeechee!" cried the youth: "What is this? where are we going? Have they killed Guatimozin, the king? If thou art the friend thou hast so often proved, row me to the shore. Methinks we are in the middle of the lake!"
