THE POSTOFFICE FEAT.
Another feat favored by some of the professional performers is that of having a letter placed in a post-office lock-box, the key of which is given the performer at a point some distance from the post-office. Rushing through the public streets, dragging the Transmitter with him, the performer finds the post-office in the usual way, and then locates the lock-box, into which he inserts the key and extracts the letter, thus triumphantly completing the feat. This feat, as every student will see, is merely a variation of the simpler feats manifested in a sensational manner for the purpose of public advertisement.
