He was not molested , however , which was most fortunate for mischief-loving yearlings , for the K.C. had stationed two tacs . in hiding close by , to be promptly on hand in case of any attempted trouble . A few nights later it came Dick Prescott 's turn to take the late tour on post number three . He was both apprehensive and watchful , but when the relief picked him up at midnight he had no report of any kind to make . It was well enough known throughout cadet camp that the superintendent and all his subordinates were bent sternly on stopping or severely punishing any attempts to interfere with sentries . As the weeks of hard work passed , and no more mysteries fell over post number three it began to be felt that plebes might thereafter walk there on the darkest night without worry . One day in July Dick found himself again on guard , with post number three for the `` ghosts promenade '' -- that is , the tour ending at midnight .
