There is no authentic statement of the revenues of James III. as Sovereign and as Earl of Orkney, but assuming and deducting a rise during the Episcopal Tacks proportioned to that which appears between the first and second Rentals of Lord Sinclair, the Skatts and Land-males of the Crown may be approximately stated at between £500 and £600. Their progressive increase during the sixteenth century may be more minutely estimated by a comparison of Lord Sinclair’s Rentals (1492–1502) with that of Earl Patrick (1600–1), and an unerring tariff of current prices is found in the Rentals themselves, or in the contemporary Rolls of the Scottish Exchequer. The last Rental of Lord Sinclair stands thus— 1502. _Scat Butter_—1312 Lispunds at 1s. per Lispund £82 0 0 _Scat Malt_—60 Lasts at £3, 6s. 8d. 200 0 0 _Forcöp_ (the exact amount of the Lawman’s fee, £12) 12 0 0 _Wattel_—12 Lasts 40 0 0 ——— —— —— Total Odal Payments £334 0 0 _Butter_, 24 Barrels (360 Lispunds) £22 10 0 _Cost_ (or Grain Rent), 88 Lasts 293 6 8 _Flesh_, 59 Lasts (118 oxen at 13s. 4d. per head) 78 13 4 —— 32 salted Marts at the same price 21 6 8 _Hawkhens_, 440 at 6d 7 6 8 ——— —— —— Total Land males of Earldom 423 3 4 ——— —— —— Total Crown’s Scats and Males £757 3 4 ==== == == These revenues, with the unrentalled profits of Wrack, Waith, Chetry, Balliatus, &c., were farmed by Tulloch and other tacksmen, at a rent or Tack duty varying from £366 to £466, till James V. (1540) ascertained by personal investigation, that under the most liberal tack, a duty of £2000 was not too high for the increased value of official perquisites, and the higher prices of conversion, which had raised the Crown’s Rental as follows— 1540. _Butter_ at £3 per Barrel £262 10 0 _Malt_ at £5 per Last 300 0 0 _Wattel_ at £5 per Last 60 0 0 _Forcop_ as before 12 0 0 ——— —— —— Total Odal payments £634 10 0
