—One of the methods of casting interest where partial payments have been made and endorsed on bonds, notes, or other securities for money, is to calculate the interest from the date of the security, or the time when the interest is to commence, to the time of the first payment endorsed, to add this to the principal, and from the sum to subtract the payment. On this remainder interest is cast to the time of the second endorsement, which is added to the remainder, and from the sum is subtracted the second endorsement. In like manner interest is cast from one payment to another, and to the time of the judgment. This method is correct, whenever the payment exceeds the amount of interest due at the time of payment; but is not to be used when the interest exceeds the payment; for the effect, in such case, would be to give compound interest, which the law does not allow.
To avoid this, the following rule has been adopted, by which every payment is first applied to keep down the interest ; * but the interest is never allowed to form a part [ * 418 ] of the principal, so as to carry interest.
Compute the interest on the principal sum, from the time when the interest commenced to the first time when a payment was made, which exceeds, either alone, or in conjunction with the preceding payments, if any, the interest at that time due; add that interest to the principal, and from the sum subtract the payment made at that time, together with the preceding payments, if any; and the remainder forms a new principal, on which compute and subtract the in*338terest, as upon the first principal; and proceed in this manner to the time of the judgment.
By this rule the interest has been computed in the case before us; and the balance, found due, having been paid to the plaintiff, he has leave to discontinue, and no costs are to be taxed for the tenant (1).
