Co-Operation between Colleges.

In view of the successful revival of the Harvard Co-operative Society, and the opening of societies at Ann Arbor and Yale based on the same principles as that at Harvard, the Advertiser suggests the possibility of extending the co-operative system by establishing a business connection between the societies which may be formed at the various colleges. "In the matter of purchasing and exchanging foreign text books, such a plan would certainly be feasible, and there seems no reason why, whenever large purchases of similar kinds are to be made by the various colleges, wholesale dealers may not be induced by the benefits obtainable from large collective orders, to be more liberal in their terms."
