In early youth his father had sailed in an East Indiaman, and during the intervals of his Indian and Chinese voyages had learned to write and add to his nautical knowledge stores of general reading and information not then common among sailors. Storing up, instead of drinking, his grog-money, he drove a small trade with the natives of these countries in little articles that had excited their curiosity, and for which, hints his distinguished son, the Custom-house dues were never very punctually or rigorously paid. Pressed, however, by a man-of-war that had borne down upon the Indiaman when in a state of mutiny, after a brief experience of the stern discipline of the navy not yet tempered by the measures of reform introduced after the mutiny of the Nore, he returned when not much turned thirty to Cromarty, where his savings enabled him to buy a coasting sloop and set up house. For this the site was purchased at £400, a very considerable sum in those days, and thus his son could, even in the high franchise qualifications after the Reform Bill, exercise the right of voting for the Whig party. The kelp trade, of which we have spoken, among other things engaged the efforts of his father, who had been appointed agent in the North and Hebrides for the Leith Glass-works. Driven by a storm round Cape Wrath and through the Pentland Firth, the vessel, after striving to reach the sheltered roadstead of the Moray Firth, was forced to put in at Peterhead. On the 9th of November 1807 he set sail, but foundered with all hands, by the starting, as was believed, of a plank. During more than one hundred years the sea had been the graveyard of the family: Miller's father, grandfather, and two grand-uncles had been all drowned at sea.
