If there be any debt of the decedent bearing interest, whether

presented or not, the executor or administrator may, by order of the

part thereof, at any time when there are sufficient funds properly

applicable thereto, whether said claim be then due or not; and

interest shall thereupon cease to accrue upon the amount so paid.
