The members of the Fairmount Athletic Club, of Philadelphia, were mainly lads under twenty years of age. There were a few older members in the club to keep everything straight and see that it was run all right, but the club was organized and conducted for the advantage of lads from fifteen to twenty-one. Not a few of the members were sons of wealthy parents, but it was not necessary for a fellow’s parents to be rich in order that he might become a member. Rich men contributed liberally to the support of the club, which made it possible for the regular fees and dues to be light, and youngsters whose parents were quite unknown, but who were regarded as “all right” themselves, obtained admission to the club. Although great precaution had been exercised not to let in any one who would be objectionable, it was impossible to exclude all objectionable parties, for, after getting in, some of the members showed traits of character which their best friends had never dreamed they possessed. Gambling in the clubrooms was prohibited, but cards, billiards and pool were permitted. There was a fine bowling alley, and the gymnasium was fitted up splendidly with all needed apparatus. In the reading-room were all the late magazines and papers, among which were the leading sporting publications. There also was a good library of books, containing volumes treating of sports and athletics. On the walls were pictures of famous amateurs, of matches, contests and races, of all sorts, and of the members of the club who had made records. Creighton had opened the club to Frank Merriwell and his friends, all of whom were led to understand that they would be welcomed there as long as they remained in Philadelphia. After leaving the girls at the tennis ground, Charlie and the others proceeded directly to the club. There they found a number of fellows assembled, waiting to see Hegner put Burk through his daily course. Burk was there, a tall, thin fellow, with short-cropped hair and a bullet-head. There was nothing attractive about his face, and there was something vicious in his little eyes. At a glance, Frank saw that the fellow selected to represent the Fairmounts had many of the characteristics of the professional prize fighter. He was hard and sinewy, quick in his movements, had a big knotty fist, and looked as if he could stand any amount of punishment. Blows would have very little effect on him, unless they were delivered with skill sufficient to knock him out. Creighton introduced Burk to the boys, and Frank talked with the fellow. It did not take Merry long to find out that, although Burk had a father who was wealthy and moved in good society, the son belonged to that class of boys who never advance beyond a certain limit, no matter how much they may be pushed. He had no fine sensibilities, and was coarse-grained in everything. “What do you think of him?” asked Charlie Creighton, as they moved away, after Frank had chatted with the young pugilist.
