The debate of the Harvard Union this evening bids fair to be among the most interesting given by that society. The subject, whether or not the Democratic party should triumph at the polls next week, is one which interests every man in college and one on which every man in college has decided opinions. The regular disputant are gentleman who thoroughly believe in the side for which they will speak and who are perfectly capable of showing up that side to the best advantage. Although there are several events tonight which may detract from the interest in this debate, there will no doubt be an audience assembled which in numbers and enthusiasm will equal any the Union ever brought together. As the college is so nearly divided in numbers on its preference for president, it is but fair to suppose that the same division exists in ability and brains, Tonight will afford an excellent opportunity for judging of the truth of this supposition.

If the night is pleasant, a large number of men will desire to witness the torchlight procession in Boston but we would remind any thus disposed that there will be plenty of time to attend part of the Union debate, as the procession will probably start with the promptness which is always observed on such occasions. We have no doubt but that the expectations of the officers of the Harvard Union will be fully realized and that the college will show its interest in the present state of politics by attending the debate in good numbers.
