Preliminary trials of the thirty-ninth annual track and field games of the Intercollegiate Association of Amateur Athletes of America, to which twenty-six colleges have sent a total of 585 entries, will take place in the Stadium this afternoon at 2.30 o'clock. Trials in three field events will begin then, and at 3 o'clock will come the first track trials.

Heats in all track events except the mile and two-mile runs will be completed today. Tomorrow the semi-finals of the two bashes and the hurdle races, and the finals of all track events will occur. All events tomorrow will begin at 3 o'clock.

In the meet Yale has the largest number of entries, 73; Cornell and Harvard stand second and third in representation, with 68 and 58 entries respectively.

Pennsylvania and Cornell Best.

From the prospects it appears that either Pennsylvania or Cornell will win, Pennsylvania having perhaps the better team of the two. Though weaker than least year, Harvard will present some strong contestants.

The fairest method of getting an idea of the comparative strength of the different teams is by considering the prospects for each event separately..

The 100-yard dash will be fought out between representatives of Cornell, Michigan and Pennsylvania. All four men who placed last year, including J. E. Patterson, of Pennsylvania who tied the record of 9 4-5 seconds, will be in the finals tomorrow. Seldom has such a remarkable field of sprinters been gathered in one race. The five men to place will probably be Patterson and Lippincott, of Pennsylvania, Bond and Seward, of Michigan, and Reller, of Cornell. Since Bond has done 9 4-5 seconds this spring and since all are capable of 10 seconds flat, the winner is extremely doubtful. One thing is certain, if weather conditions are favorable, the victor will have to do 9 4-5 seconds or better.

Practically the same story may be told for the 220-yard dash. However, if W. A. Barron, Jr., '14, decides to enter this event after competing in the quarter mile, he probably will place. Lippincott, of Pennsylvania, in winning this event last year, tied the record of 21 1-5 seconds. Barron went 1-5 of a second slower at Ithaca; however, Bond, of Michigan has been caught in 21 seconds flat. Acording to his performances this spring, the latter should capture this event, with Lippincott a close second.

Barron and Meredith in Quarter.

In the 440-yard run a great deal depends on the draw. If Barron is fortunate in this respect he should win the race. However, if Meredith, of Pennsylvania, decides to run in the quarter he will make a very dangerous competitor. Janson, of Michigan, should take a place unless he saves himself for the half, and Wilkie, of Yale, and W. J. Bingham '16 should both gain points with Caldwell, of Cornell, Lockwood, of Princeton, and J. C. Rock '15 as other contestants.

Undoubtedly the feature of the day will be the half-mile, with Brown, of Yale, and Meredith, of Pennsylvania, as the chief contenders. The latter, who holds the world's record of 1 minute, 52 1-2 seconds, should win this event, especially if he saves himself for it by keeping out of the quarter. Brown did 1 minute, 54 seconds two weeks ago and can undoubtedly reduce this, but hardly enough to defeat Meredith. At all events, J. P. Jones's record of 1 minute, 53 4-5 seconds, will probably be lowered, if running conditions are at all favorable. F. W. Capper '15 should place in this race. Granger, of Dartmouth and Jansen, of Michigan, complete the quintet that should carry off the five places. Caldwell, of Cornell, and Hayes, of Princeton have both made good times.

Madeira, Spelden, Best In Mile

Speiden, of Cornell, and Madeira, of Pennsylvania, are the two leading competitors in the mile run with the odds favoring the latter, although both have made 4 minutes, 19 4-5 seconds. Marceau, of Dartmouth, should be a close third, while Wood, of California, Poucher, of Yale and McKenzie, of Princeton, will fight it out for the last two places. There is little danger of J. P. Jones's record being broken in this race tomorrow, but the men are so evenly matched that an unusually fast time will result.

Another Pennsylvania man, McCurdy, is the favorite for the two-mile run, and should repeat his victory of last year. McCurdy has made 9 minute. 35 seconds this spring, several seconds better than anyone else. Hoffmire, of Cornell and R. St. B. Boyd '14 are expected to engage in a duel for second place. Boyd has done excellent work in practice since the Yale meet, when he beat Hoffmire's time in the Cornell meet by 5 seconds, and should not only take second place, but should give McCurdy a hard fight. the winners of fourth and fifth places should be Clark, of Yale, and Potter, of Cornell, with Cook of Technology close up.

The high hurdles will fall to Potter, of Yale, or Braun, of Dartmouth, although Hammitt, of Penn State, will make it close. A. L. Jackson '14, has been showing improved form and should land in the scoring with a fourth or possible third. Armstrong, of Michigan and Ferguson, of Pennsylvania have both done 16 seconds as has Preble, of California; so there is very little to choose between them.
