More than that, he deduced, the man had vanished and yet, after he was gone, there had come that unexpected descent of the rolling door which had first made them think themselves trapped. Sandy argued, and with good common sense, that a ghost, in broad sunny daylight, was a silly way to account for the man. He also felt that it was equally unjust to credit the drop of the door to gravity. Friction drums are not designed to allow the ropes on them to slip, especially if there is no jolt or jar to shake them. Walpole, however, continued to oppose the South Sea Bill in the Commons, declaring that the terms were too extravagant ever to be fulfilled; that the experiment could result in nothing but a fearful increase of the costs of stockjobbing, and final confusion and ruin. He insisted that, before the proposals of the Company were accepted,[47] the rise of their stock should be limited, and every means taken to prevent the fever of infatuation that would ensue from the promise of dividends out of funds which could never be realised. He proposed for this purpose the introduction of a clause fixing the number of years' purchase to be granted to the annuitants of the South Sea Company; but to this it was objected that it was the interest of the Company to take up the annuities; and, as the annuitants had the power of coming in or not, as they pleased, the Company would, of course, offer advantageous terms, and, therefore, the whole affair might be safely left to private adjustment. Aislabie added that the South Sea Company would not submit to be controlled in an undertaking they were to pay so dear for. The Bill passed both Houses. As the woollen manufactures of Ireland had received a check from the selfishness of the English manufacturers, it was sought to compensate the Protestants of Ulster by encouraging the linen manufacture there, which the English did not value so much as their woollen. A Board was established in Dublin in 1711, and one also in Scotland in 1727, for the purpose of superintending the trade, and bounties and premiums on exportation were offered. In these favourable circumstances the trade rapidly grew, both in Ireland and Scotland. In 1750 seven and a half million yards of linen were annually woven in Scotland alone. "Pardon me, Lieutenant¡ªI should perhaps say Captain"¡ªinterrupted Lieut. Bowersox, with much sweetness of manner, "but the most of us are familiar with your views as to the inferiority of the discipline of the Western Armies to that of the Army of the Potomac and European armies, so that we need not take up the' time of the court with its reiteration. What farther happened?" "Sure," Dodd said. "But I mean people. And you want the same things we do. You want a little comfort out of life, a little security¡ªsome food, say, and enough food for tomorrow. Right?" "Why, two shillings is too much fur farm-folks lik us to give fur a pound of chocolate. It's naun but a treat, and we can do wudout it." At last they came to Castweasel¡ªthree old cottages and a ruined one, leaning together in a hollow like mushrooms. Beside the ruined cottage a tree-trunk was lying, and Rose suddenly stretched herself with a little sigh. "I'm sorry," he said sheepishly. Rate, skate, and crabs. Farewell, farewell, you jolly young girls! HoMEɧµÄ»¤Ê¿ÃÃÃÃ
