" Compute the interest to the time of the first payment, if that be one yerir "or more from the time the interest commenced, add it to the principal, and deduct the payment from the sum total. If there be after payments made, compute the interest on the balance due to the next payment, and then deduct the payment as above, and in like manner from one payment to another, till all the payments are absorbed ; provided the tiine between one payment and another be one year or more. But if any payment be made before one year's interest bath accrued, then compute the interest on the principal sun due on the obligation for one year, add it to the principal, and compute the interest or. the sum paid, from the time it was paid, up to the end os the year: add it to the sum paid, and deduct that suin from the principal and interest added as above.* "If any payments be made of a less sum than the interest arisen at the time of such payment, no interest is to be coni puted but only on the principal sum for any period."
