Mr Barlow.—If you understood arithmetic you might do it in five minutes.
Tommy.—That is extraordinary, indeed; I can hardly conceive it possible.
Mr Barlow.—A bushel of corn weighs about fifty pounds; this sack contains four bushels; so that there are just two hundred pounds weight in all. Now, every pound contains sixteen ounces, and sixteen times two hundred makes thirty-two hundred ounces. So that you have nothing to do but to count the number of grains in a single ounce, and there will be thirty-two hundred times that number in the sack.
Tommy.—I declare this is curious indeed, and I should like to learn arithmetic. Will Harry and you teach me, sir?
Mr Barlow.—You know we are always ready to improve you. But before we leave this subject, I must tell you a little story. "There was a gentleman who was extremely fond of beautiful horses, and did not grudge to give the highest prices for them. One day a horse-courser came to him, and showed him one so handsome, that he thought it superior to all he had ever seen before. He mounted him, and found his paces equally excellent; for, though he was full of spirit, he was gentle and tractable as could be wished. So many perfections delighted the gentleman, and he eagerly demanded the price. The horse-courser answered, that he would bate nothing of two hundred guineas; the gentleman, although he admired the horse, would not consent to give it, and they were just on the point of parting. As the
man was turning his back, the gentleman called out to him, and said, 'Is there no possible way of our agreeing, for I would give you anything in reason for such a beautiful creature?' 'Why,' replied the dealer, who was a shrewd fellow, and perfectly understood calculation, 'If you do not like to give me two hundred guineas, will you give me a farthing for the first nail the horse has in his shoe, two farthings for the second, four for the third, and so go doubling throughout the whole twenty-four, for there are no more than twenty-four nails in all his shoes?' The gentleman gladly accepted the condition, and ordered the horse to be led away to his stables."
Tommy.—This fellow must have been a very great blockhead, to ask two hundred guineas, and then to take a few farthings for his horse.
Mr Barlow.—The gentleman was of the same opinion; "however, the horse-courser added:—'I do not mean, sir, to tie you down to this last proposal, which, upon consideration, you may like as little as the first; all that I require is, that if you are dissatisfied with your bargain, you will promise to pay me down the two hundred guineas which I first asked.' This the gentleman willingly agreed to, and then called the steward to calculate the sum, for he was too much of a gentleman to be able to do it himself. The steward sat down with his pen and ink, and, after some time, gravely wished his master joy, and asked him, 'in what part of England the estate was situated that he was going to purchase.' 'Are you mad?' replied the gentleman; 'it is not an estate, but a horse, that I have just bargained for; and here is the owner of him, to whom I am
going to pay the money.' 'If there is any madness, sir,' replied the steward, 'it certainly is not on my side; the sum you have ordered me to calculate comes just to seventeen thousand four hundred and seventy-six pounds, besides some shillings and pence; and surely no man in his senses would give this price for a horse.' The gentleman was more surprised than he had ever been before, to hear the assertion of his steward; but when, upon examination, he found it no more than the truth, he was very glad to compound for his foolish agreement, by giving the horse-courser the two hundred guineas, and dismissing him."
Tommy.—This is quite incredible, that a farthing just doubled a few times, should amount to such a prodigious sum; however, I am determined to learn arithmetic, that I may not be imposed upon in this manner, for I think a gentleman must look very silly in such a situation.
