The program is a notable one, comprising the following matches: Jimmie Barry vs. Johnnie Conners; George Kerwin vs. Otto Sieloff; Link Pepo vs. “Kid” Harris; Billv Stift vs. AHShrosbee and Jack Everhart vs “Kid” McGlenn. The Kerwin-Sie-loff contest, though the principalsare not so well known as some of the others figuring in the program, is attracting a good deal of attention as each man has a list of knockouts to his credit and is generally regarded as only wanting an opportunity to defeat some of the big ones to spring to the front rank. Kerwin. who has earned the name of “the mystery” by his peculiar style of fighting, has a little bit the better of it in the betting. Sieloff realizing that a. victory over Kerwin would mean a great deal to him at the present time and is training faithfully to put himself into the pink of condition. The victor ofthe contest is expected to go east and try his luck against such men as McKeever, Daly, Everhart and Zeigler in six round contests.
