The third method of obtaining the essays of other persons, is called "transmission" (ch'uan ti). This can only be accomplished by the coöperation of the inspectors (hsün ch'ang) who, like all other mortals, are supposed to be perfectly open to considerations of temporal advantage, if only arguments of sufficient strength are employed. As soon as the Chancellor's theme is announced, it is copied, and at a preconcerted signal thrown over the wall of the examination premises to persons waiting for it. Several scholars outside may have been previously engaged to write essays for different persons within the hall. When the essays are finished they are carefully done up, and at a signal, such as a call for a dog or for a cat, are thrown over the wall to the watchman, who has been previously paid to receive them. The inspector, also liberally fed, ascertains from a private mark on each essay, for whom it is intended, and while pacing back and forth through the hall, contrives to deliver them, without being seen by the Chancellor. In one case, six persons were known to have received their degrees, on the merits of essays which were brought into the hall after being thrown over the wall in a single bundle. Sometimes essays are concealed in the body of a harmless-looking bread-cake, which is tossed carelessly from one candidate to another when the lunches are eaten, with the connivance, no doubt, of the inspectors. The District Magistrates sometimes post the Secretaries at the corners of the examination hall, where it is easy to see all that goes on. But much more often, it is probable, that the Magistrate takes little interest in such details. In some examinations, the Chancellors are very strict, and forbid any of the watchmen to enter the hall at all, which, of course, checkmates the plan last described. Such instances are much more than offset by others, in which the Chancellor does not remain through the examination himself, but entrusts the conduct of affairs to his Secretaries. These functionaries are then at liberty to furnish essays to candidates who can afford to pay the heavy price necessary. In such cases, while ostensibly examining the essays, the Secretaries find it easy to throw one of their own under a stool, or in some place from which it may be readily captured by the purchaser.
