In the midst of this agitation, the smallpox broke out in the capital, and the Governor was compelled to move the General Assembly to Cambridge. Here in January, 1764, another misfortune occurred. Harvard Hall was burned to a heap of ruins, the only one of the ancient buildings which still remained. Of five thousand volumes, only a hundred were saved, and of John Harvard's books, but a single one. The Governor at once appealed to the Assembly and obtained a vote for reconstruction. He set the example of contributing towards a new library by the gift of some of his own books; he also drew the architectural design for the new building and superintended its execution. Subscriptions were made both in England and America for the erection of the new hall. In June 1763, a confederation of several Indian tribes had suddenly and unexpectedly swept over the whole western frontier of Pennsylvania and Virginia, had murdered almost all the English settlers, and through unusual skill captured every British fort between the Ohio and Lake Erie, and had closely blockaded Fort Detroit and Pittsburg. After desperate fighting, the troops under Amherst succeeded in repelling the invaders and secured the three great fortresses of Niagara, Detroit and Pittsburg. The severe fighting appears to have been done by the English troops. Massachusetts seemed to be fatigued from the late war and could give no help when aid was asked. Connecticut finally sent 250 men. Peace was signed in September, 1764, the war having lasted fourteen months, months of extreme horror. The credit of the war belonged to the English soldiers, another great service rendered to the colonies by England. England felt that the colonies should help share the great expense of the late wars. George Grenville as First Lord of the Treasury, and Chancellor of the Exchequer, signalized his period of administration by the Stamp Act. On the 10th of March the House of Commons on the motion of the Minister, passed a variety of resolutions respecting certain duties on foreign goods imported into the British colonies of America. Grenville remarked in his honest way to the colonial agents in London, "I am not, however, set upon this tax. If the Americans dislike it, and prefer any other method, I shall be content. Write therefore, to your several colonies, and if they choose any other mode, I shall be satisfied, provided the money be but raised."[163] [163] Samuel Adams (Hosmer) Ch. VI.
