Then the lesson began, and the twenty-five boys had to display their industry and interest with respect to boric acid, and chlorine, and strontium, as in the previous period they had displayed it with respect to Ovid. Hans Hermann Kilian was commended because he knew that BaSO_{4}, or barytes, was the metal most commonly used in counterfeiting. He was the best in the class, anyhow, because of his desire to be an officer. Kai and Hanno knew nothing at all, and fared very badly in Dr. Marotzke’s notebook. And when the tests, recitation, and marking were over, the interest in chemistry was about exhausted too. Dr. Marotzke began to make a few experiments; there were a few pops, a few coloured gases; but that was only to fill out the hour. He dictated the next lesson; and then the third period, too, was a thing of the past. Everybody was in good spirits now--even Petersen, despite the blow he had received. For the next hour was likely to be a jolly one. Not a soul felt any qualms before it, and it even promised occasion for entertainment and mischief. This was English, with Candidate Modersohn, a young philologian who had been for a few weeks on trial in the faculty--or, as Kai, Count Mölln, put it, he was filling a limited engagement with the company. There was little prospect, however, of his being re-engaged. His classes were much too entertaining. Some of the form remained in the chemistry hall, others went up to the classroom; nobody needed to go down and freeze in the courtyard, because Herr Modersohn was in charge up in the corridors, and he never dared send any one down. Moreover, there were preparations to be made for his reception. The room did not become in the least quieter when it rang for the fourth hour. Everybody chattered and laughed and prepared to see some fun. Count Mölln, his head in his hands, went on reading Roderick Usher. Hanno was audience. Some of the boys imitated the voices of animals; there was the shrill crowing of a cock; and Wasservogel, in the back row, grunted like a pig without anybody’s being able to see that the noise came from his inside. On the blackboard was a huge chalk drawing, a caricature, with squinting eyes, drawn by Timm the rhapsodist. And when Herr Modersohn entered he could not shut the door, even with the most violent efforts, because there was a thick fir-cone in the crack; Adolf Todtenhaupt had to take it away.
