Kansas guard Colorado's Fortunes Riding On Weidner's Passing Arm (Editor's Note: This is one of seven articles describing the prospects and problems of KU's conference foes this season in football.) BOULDER -Coach Sonny Grandelius' Golden Buffaloes, building their offensive hopes on the pitching arm of sensational Gale Weidner; will be highly improved with 27 returning lettermen. The Buff offense will probably be aerial-dominated again with Weidner running the team supplemented by a good corps of receivers forming the major weapon. The running attack is full of question marks. It was non-existent last year until late in the season. Coach Grandelius feels his defense will be improved but weak, although the new substitution rule will enable the coaching staff to shore up weak spots which may crop up in the line and deep secondary. End and quarterback are the strongest positions in Colorado's variable-T offense. Five proven veterans and good young prospects form one of the finest end corps in the midlands. Weidner heads a solid-looking group at quarterback with Frank Montera and Clark Weaver backing him. The Buffaloos opening game will be Sept. 24 against highly-touted Baylor. Arizona and the Air Force Academy round out Colorado's non-conference foes. Coach Grandelius points to three factors as probably the keys to Golden Buffalo success. Overall speed needs to be improved vastly and halfback speed is still a major shortcoming. At tackle, Bob McCullough is the only topnotch member and he has been plagued by injuries to his leg and shoulder. This is the weakest position. Center is another weak link with injuries slowing first-liner Walt Klinker during spring practice. 59 Rats Like Men Actresses Team Again The whole rat pack is being used in tests of space chambers, because the rats, collectively, use about the same amount of oxygen and give off about the same amount of carbon dioxide and moisture as one human.

BURLINGTON, Vt. (UIP) — Enoch Tompkins, University of Vermont assistant agricultural economist and president of the Vermont Beekeepers Association, said "It's the nectar which makes the honey" produced by bees.
