Ewan Callister, assistant to the revenue officer at Douglas before the Revestment.

He was paid three pounds Manx a year, the same as Paul Bridson whom he assisted, and more than the assistant at Castletown, who had one pound. The whole of the Duke of Atholl's revenue establishment for the Island cost forty-nine pounds thirteen shillings and fourpence Manx, against collections running at between five and six thousand pounds a year over a ten-year average, and a Receiver General at forty pounds stood outside that figure. Douglas, where Callister served, was the first port of the Island, and the two men there were paid the same.

The Duke printed those figures for a reason. He was answering the suggestion that his officers had done well out of the trade, and he set the salaries against the reputation: when he heard of people on such pay as this living splendidly, bringing up numerous families or dying opulent, he left his readers to draw the conclusion.
