LONDON, June 17. - The challenges sent by the athletic clubs of Oxford and Cambridge Universities to the athletic clubs of Yale and Harvard Universities were posted on June 10th, left for New York on June 13 by White Line steamer Germanic, due to reach that port on June 20th. Although two challenges were sent, they are identical in wording, one copy was sent to the captain of the Yale athletic club and another one to the captain of the Harvard athletic club. The challenges are worded as follows:

"HERTFORD COLLEGE, Oxford, June 10,1895."To the Captain of the Harvard Athletic Association:

"DEAR SIR: - A joint committee of the Oxford University Athletic Club and the Cambridge University Athletic Club, at a conference held at Oxford, resolved to send a challenge to the universities of Yale and Harvard, inviting them to partake in an athletic competition, to take place in America at some date in the autumn as may mutually be agreed upon.

"The committee considered the possibility of sending a joint team in the middle of July, but, on going into the question, found it would not be practicable, because some of the best athletes would be unable to leave England at that time, being detained by the public examinations, whilst others who had already engaged themselves to take part in the forthcoming competition of the London Athletic Club vs. the New York Athletic Club were not prepared to go to America in July and also in September. You will see that our only course was to suggest to you an autumn meeting, which may come before or come after the fixture already agreed upon between the London Athletic Club and the New York Athletic Club, as may hereafter be deemed best, and we send a challenge subject to all the preliminaries being satisfactorily arranged.

"We would suggest that the programme contain the following events:

"Flat races - 100 yards dash, quarter mile run, half mile run, mile run and three mile run.

"Hurdle races - 120 yards, one according to English rules and one according to American rules.

"High jump, long jump, hammer throw, and weight putting.

"We shall be glad to be favored with your reply at your earliest convenience, as all arrangements have to be concluded before the end of this term.

"Yours very truly,"W. J. OAKLEY,"President of the Oxford University Athletic Club.

"F. S. HORAN,"President of the Cambridge University Athletic Club."
