That Isidro persevered during the next week, the Maestro also came to know. For now regularly every evening as he smoked and lounged upon his long, cane chair, trying to persuade his tired body against all laws of physics to give up a little of its heat to a circumambient atmosphere of temperature equally enthusiastic; as he watched among the rafters of the roof the snakes swallowing the rats, the rats devouring the lizards, the lizards snapping up the spiders, the spiders snaring the flies in eloquent representation of the life struggle, his studied passiveness would be broken by strange sounds from the dilapidated hut at the back of his house. A voice, imitative of that of the Third Assistant who taught the annex, hurled forth questions, which were immediately answered by another voice, curiously like that of Isidro. Fiercely: "Du yu ssee dde hhett?" Breathlessly: "Yiss I ssee dde hhett." Ferociously: "Show me dde hhett." Eagerly: "Here are dde hhett." Thunderously: "Gif me dde hhett." Exultantly: "I gif yu dde hhett." Then the Maestro would step to the window and look into the hut from which came this Socratic dialogue. And on this wall-less platform which looked much like a primitive stage, a singular action was unrolling itself in the smoky glimmer of a two-cent lamp. The Third Assistant was not there at all; but Isidro was the Third Assistant. And the pupil was not Isidro, but the witless old man who was one of the many sharers of the abode. In the voice of the Third Assistant, Isidro was hurling out the tremendous questions; and, as the old gentleman, who represented Isidro, opened his mouth only to drule betel-juice, it was Isidro who, in Isidro's voice, answered the questions. In his role as Third Assistant he stood with legs akimbo before the pupil, a bamboo twig in his hand; as Isidro the pupil, he plumped down quickly upon the bench before responding. The sole function of the senile old man seemed that of representing the pupil while the question was being asked, and receiving, in that capacity, a sharp cut across the nose from Isidro-the-Third-Assistant's switch, at which he chuckled to himself in silent glee and druled ad libitum. For several nights this performance went on with gradual increase of vocabulary in teacher and pupil. But when it had reached the "Do you see the apple-tree?" stage, it ceased to advance, marked time for a while, and then slowly but steadily began sliding back into primitive beginnings. This engendered in the Maestro a suspicion which became certainty when Isidro entered the schoolhouse one morning just before recess, between two policemen at port arms. A rapid scrutiny of the roll-book showed that he had been absent a whole week. "I was at the river cleaning my trousers," answered Isidro when put face to face with this curious fact.
