What is the limit of human) endurance as far as track and field performances go? Some of the smartest minds in the sport have given that one more than a once over lightly in the past and have been far off the mark in their prognostications. Take the case of Brutus Hamilton, for instance. Hamilton, track and field coach at the University of California, more than 10 years ago | stuck out his neck and forecast the; ultimate, in his opinion, that the thinclads would attain. : An astute student of the sport, | Brutus the Bear got out his slide| rule, figured all the angles and came up with his announcement. If “anyone should come close to! predicting the ultimate in track and| field performing, it should be Ham-| ilton, as this is one vet who know his stuff. But, although we haven’t had much doings in track and field for the past four years, his forecasts| today, 10 years after they were} made, could stand some revision. | He didn’t set his sights high; enough, Most of his ultimates either al- ready have been exceeded or the! present world’s record is creeping perilously upon them. Some of them, however, still are above the present record. For instance, Hamilton thought no pole vaulter ever would top 15 feet 18-100 inches then. In 1941 Cor- nelius Warmerdam, the Fresno ace, was credited with a leap of 15 feet 5% inches and no less than 14 times has bettered Hamilton's figure! | And in the high jump he thought the ceiling would be 6 feet 11 22-100 inches. (Note that he cut it right down to fractions.) The present of- ficial world mark is 6 feet 11 inches.
