We publish this morning a communication from "'84," in which he takes the ground that the Dining Association is paying an exorbitant rate of interest for money loaned it by the corporation. It is undoubtedly true that almost any one who is "good" can borrow any amount of money at about four per cent., and only a short time ago we saw a note given for $10,000, on which interest was paid at the rate of three and one-half per cent. Now, why does the Dining Association have to pay seven per cent.? Is the association not on a good, solid basis, or is the corporation "afraid of it?" We agree with our correspondent that something ought to be done about this matter at once.
