    If default is made in the interest due upon money loaned by any township treasurer, or in the payment of the principal, interest at the rate of 12 per cent per annum shall be charged upon the principal and interest from the day of default, which interest shall be included in the assessment of damages, or in the judgment in the suit or action brought upon the obligation to enforce payment thereof, and interest at the rate of 12 per cent per annum may be recovered in an action brought to recover interest only. The township treasurer may bring appropriate actions in the name of the trustees for the recovery of the interest when due and unpaid, without suing for the principal, in whatever form secured.
