One night, he made a rough calculation of the number of hides that could be stowed in the lower hold, between the fore and main masts, taking the depth of hold and breadth of beam (for he always knew the dimension of every part of the ship, before he had been a month on board), and the average area and thickness of a hide; he came surprisingly near the number, as it afterwards turned out. The mate frequently came to him to know the capacity of different parts of the vessel, so he could tell the sailmaker very nearly the amount of canvas he would want for each sail in the ship; for he knew the hoist of every mast, and spread of every sail, on the head and foot, in feet and inches. When we were at sea, he kept a running account, in his head, of the ship’s way—the number of knots and the courses; and if the courses did not vary much during the twenty-four hours, by taking the whole progress, and allowing so many eighths southing or northing, to so many easting or westing; he would make up his reckoning just before the captain took the sun at noon, and often came wonderfully near the mark. Calculation of all kinds was his delight. He had, in his chest, several volumes giving accounts of inventions in mechanics, which he read with great pleasure, and made himself master of. I doubt if he ever forgot anything that he read. The only thing in the way of poetry that he ever read was Falconer’s Shipwreck,186 which he was delighted with, and whole pages of which he could repeat. He knew the name of every sailor that had ever been his shipmate, and also, of every vessel, captain, and officer, and the principal dates of each voyage; and a sailor whom he afterwards fell in with, who had been in a ship with Harris nearly twelve years before, was very much surprised at having Harris tell him things about himself which he had entirely forgotten. His facts, whether dates or events, no one thought of disputing; and his opinions, few of the sailors dared to oppose; for, right or wrong, he always had the best of the argument with them. His reasoning powers were remarkable. I have had harder work maintaining an argument with him in a watch, even when I knew myself to be right, and he was only doubting, than I ever had before; not from his obstinacy, but from his acuteness. Give him only a little knowledge of his subject, and, certainly among all the young men of my acquaintance and standing at college, there was not one whom I had not rather meet, than this man. I never answered a question from him, or advanced an opinion to him, without thinking more than once. With an iron memory, he seemed to have your whole past conversation at command, and if you said a thing now which ill agreed with something said months before, he was sure to have you on the hip. In fact, I always felt, when with him, that I was with no common man. I had a positive respect for his powers of mind, and felt often that if half the pains had been spent upon his education which are thrown away, yearly, in our colleges, he would have been a man of great weight in society. Like most self-taught men, he overestimated the value of an education; and this, I often told him, though I profited by it myself; for he always treated me with respect, and often unnecessarily gave way to me, from an overestimate of my knowledge. For the intellectual capacities of all the rest of the crew, captain and all, he had the most sovereign contempt. He was a far better sailor, and probably a better navigator, than the captain, and had more brains than all the after part of the ship put together. The sailors said, “Tom’s got a head as long as the bowsprit,” and if anyone got into an argument with him, they would call out—“Ah, Jack! you’d better drop that, as you would a hot potato, for Tom will turn you inside out before you know it.”
I recollect his posing me once on the subject of the Corn Laws. I was called to stand my watch, and, coming on deck, found him there before me; and we began, as usual, to walk fore and aft, in the waist. He talked about the Corn Laws;187 asked me my opinion about them, which I gave him; and my reasons; my small stock of which I set forth to the best advantage, supposing his knowledge on the subject must be less than mine, if, indeed, he had any at all. When I had got through, he took the liberty of differing from me, and, to my surprise, brought arguments and facts connected with the subject which were new to me, to which I was entirely unable to reply. I confessed that I knew almost nothing of the subject, and expressed my surprise at the extent of his information. He said that, a number of years before, while at a boardinghouse in Liverpool, he had fallen in with a pamphlet on the subject, and, as it contained calculations, had read it very carefully, and had ever since wished to
