2. In general a suspender is required to give caution to pay the debt in the event it shall be found due. Where the suspender cannot, from his low or sus-pected circumstances, procure unquestionable security, the lords admit jura-tory caution; but the reasons of suspension are in that case, to be considered with particular accuracy at passing the bill. Act. S. 8 Nov. 1682; Ersk. Prin. L. Scot. 4, 3, 6.
