Scott was a celebrated gambler, whose skill and phenomenal luck gained him a fortune estimated at £500,000.
His seat was tenable for one Parliament only, since Caithness would not be represented in the next Parliament, and early in 1757 he made plans to secure his return as Member for the Northern (Tain) Burghs. He was on friendly terms with William, 18th Earl of Sutherland (great nephew of James St. Clair, his commanding officer), whose sister was married to his old Fife acquaintance James Wemyss of Wemyss. Sutherland offered Scott his interest in the burghs of Dornoch and Wick, and in the summer of 1757 accompanied Scott to the north to begin his campaign.
Give me leave to thank your Grace for your assistance to Colonel Scott. Let me say a word for him independent of me. I exceedingly condemn any improper expression, I dare say he is sorry for it, but he is rough and never sacrificed to the Graces. In act he has not failed during the whole Parliament in a single instance, and last session singly carried the malt bill, though in opposition to Scotch politics and though he was sure to displease the Duke of Argyll and others by it ... I should hope your Grace would reckon him among the number who have adhered faithfully to you without fee or reward.
Add. 32874, ff. 35-36.
In the new Parliament Scott deserted Newcastle for Bute, and was among those listed by Fox as favourable to the peace preliminaries. He wrote, 27 Nov. 1762, to the Earl of Sutherland:
We shall have a fine riot in Parliament this winter but I don’t believe the Opposition will be able to muster above 120 or 130, although Billy Cumberland, Lucky Newcastle, the Nurse [Hardwicke], and Pitt have all joined.
Scott was well known to Shelburne, having been one of his hosts and sponsors in Edinburgh society during his visit 1759-60;
He was now a man of great wealth. ‘As rich as Scott’ was becoming a proverb.
I think we that are considerable East India proprietors have likewise reason to complain of the measure of allowing such a hurlo-thrumbo as Beckford and a declared enemy to the Company to make the motion in so hostile a manner; if it had come in a decent manner from the Treasury bench I for one should have supported instead of opposing it.
Scott’s unsavoury dealings in the Northern Burghs made his re-election there unlikely, especially as Lord Sutherland had given no guarantee for 1768 and was negotiating with the Mackays. In 1765 Anstruther Burghs fell vacant and Scott, seizing the opportunity to represent a district in his native Fife, proposed to his friends Wemyss and Sutherland to resign his seat in favour of a candidate nominated by himself, and with the assistance of the Wemyss interest to contest Anstruther burghs. But neither Sutherland nor Wemyss would come into this.
After his victory Scott went on a visit to America and his name does not appear in the division lists of 1769 on Wilkes and the Middlesex election. William Allen, merchant and chief justice of Pennsylvania, wrote on 7 Nov. 1769:
I had a good deal of conversation with Colonel Scott, a Member of Parliament, who last year travelled through the colonies, who agreed with me that most of the late commercial regulations were absurd and injurious to both countries; and he with great confidence assured me that they would be repealed, and matters put upon the old system.
But dissatisfaction with Government policy does not seem to have carried him into opposition, and to the end of his life he continued to vote with Administration.
He died 7 Dec. 1775. George Selwyn wrote to Lord Carlisle:
General Scott is dead ... The place of Nickster which is in the Devil’s gift and vacated by John Scott is not disposed of. We go into mourning on Thursday. The waiters are to have crepes round their arms and the dice to be black and the spots white, during the time of wearing weepers, and the dice box muffled.
He suggested a motto: ‘Sic Dice placuit’.
