It frequently happens that the teacher is himself one of the literary army who attends the examinations in hope of a degree. If this is the case, his absences for this purpose will often prove a serious interruption to the routine of the school. Some patrons appear to consider that this disadvantage is balanced by the glory which would accrue to their school in case its master were to take his degree while in their service. Moreover, aside from the regular vacations at the feast times and harvests, every teacher is sure to be called home from time to time by some emergency in his own family, or in his village, or among his numerous friends. Under these circumstances he provides a substitute if he happens to find it convenient to do so. Such are nicknamed "remote-cousin-preceptors" (_su-pai lao-shih_), and are not likely to be treated with much respect. When the teacher is absent for a day, instead of dismissing the school, he perhaps leaves it theoretically in the charge of one of the older scholars. The inevitable consequence is, that at such times the work of the school is reduced not merely to zero, but to forty degrees below zero. The scholars simply bar the front door, and amuse themselves in using the teacher's ferule for a bat, and the Trimetrical Classic, or the Confucian Analects, for a ball. The demoralization attending such lawlessness is evidently most injurious to the efficiency of the school. The irregularities of the master's attendance are more than matched by those of his scholars. The pressure of domestic duties is such that many poorer families on one pretence or another are constantly taking their children out of school. To-day the pupil must rake up fuel, next week he must lead the animal that draws the seed drill, a month later he is taken for two or three days to visit some relatives. Not long after there is in the village, or perhaps in some neighbouring village, a theatrical entertainment, but in either case the whole school expects a vacation to go and see the sport. As already remarked when describing theatricals, if this vacation were denied they would take it themselves. Besides interruptions of this sort, there are the spring and autumn harvests, when the school is dismissed for two months and perhaps for three, and the New Year vacation, which lasts from the middle of the twelfth moon to the latter part of the first moon. But, extensive as are these intermissions of study, the dog-days are not among them, and the poor pupils go droning on through all the heat of summer.
