FORE:The progress of our manufactures was equally satisfactory. At the commencement of this period that great innovator and benefactor, the steam-engine, was produced. The idea thrown out by the Marquis of Worcester, in his "Century of Inventions," in 1663, had been neglected as mere wild theory till Savery, in 1698, constructed a steam-engine for draining mines. This received successive improvements from Newcomen and Crawley, and further ones from Brindley in 1756, and Watt extended these at the end of this period, though this mighty agent has received many improvements since. Navigable canals, also, date their introduction by the Duke of Bridgewater, under the management of Brindley, from the latter end of this period, 1758. Other great men, Arkwright, Compton, Hargreaves, etc., were now busily at work in developing machinery, and applying steam to it, which has revolutionised the system of manufacture throughout the world. In 1754 the Society of Arts and Manufactures was established.Warren Hastings had saved Madras and the Carnatic, but only at the cost of extortion. To obtain the necessary money, he began a system of robbery and coercion on the different princes of Bengal and Oude. The first experiment was made on Cheyte Sing, the Rajah of Benares, who had been allowed to remain as a tributary prince when that province was made over to the British by the Nabob of Oude. The tribute had been paid with a regularity unexampled in the history of India; but when the war broke out with France, Hastings suddenly demanded an extraordinary addition of fifty thousand pounds a year, and as it was not immediately paid, the Rajah was heavily fined into the bargain. This was rendered still more stringent in 1780, when the difficulties in Madras began. Cheyte Sing sent a confidential agent to Calcutta, to assure Hastings that it was not in his power to pay so heavy a sum, and he sent him two lacs of rupees (twenty thousand pounds), as a private present to conciliate him. Hastings accepted the money, but no doubt feeling the absolute need of large sums for the public purse, he, after awhile, paid this into the treasury, and then said to Cheyte Sing that he must pay the contribution all the same. He compelled the Rajah to pay the annual sum of fifty thousand pounds, and ten thousand pounds more as a fine, and then demanded two thousand cavalry. After some bargaining and protesting, Cheyte Sing sent five hundred horsemen and five hundred foot. Hastings made no acknowledgment of these, but began to muster troops, threatening to take vengeance on the Rajah. In terror, Cheyte Sing then sent, in one round sum, twenty lacs of rupees (two hundred thousand pounds) for the service of the State; but the only answer he obtained for the munificent offering was, that he must send thirty lacs more, that is, altogether, half a million.
