It is natural to suppose that documents of this kind should come to be used as a sort of currency, in a district where money is so scarce as Shetland. This custom is not so wide-spread as might have been expected; but that lines are frequently transferred by the original holder, is clearly enough proved. The merchants who issue them are chary of admitting that such transfers are made, and some even seem to think it necessary to take precautions against such a proceeding. That the practice exists appears from the evidence of Mr. Sinclair's chief shopman, who admits that he has heard a 'vague report' that the lines have been exchanged; and when asked to explain the entry 'To lines' occurring in accounts in the journal or work-book, says: '... Sometimes the party that the account belongs to will have to pay another party so much, and she gives us instructions to mark a line for a certain amount in the book, and then give her that line to give to the other party, who comes back with it and gets the amount in goods.' '3383. Then the line is granted to your knitters for the purpose of paying their debt to another?-Yes.' '3384. Is that frequently done?-Not very often. It has happened occasionally.' [J.J. Bruce, 3355; R. Sinclair, 2581, 2591, 3617.] The evidence of the knitters themselves proves that the practice of selling or exchanging these lines is quite usual and well-known among the more necessitous of them, <i.e.> those who have no means of living but knitting. One respectable merchant in Lerwick gave up the practice of issuing lines, on account of the trouble and annoyance occasioned by this practice. [E. Robertson, 248; M. Hutchison, 1592; E.
