The history of the present _deposit_ may be briefly told. Earl Temple's papers were always kept at Stowe, the well-known and superb mansion of the Buckingham family. A considerable portion of Mr Grenville's correspondence, preserved at Wotton, was brought to Stowe, and arranged with that of Earl Temple, and the remainder was discovered by the editor, in a large chest at Buckingham House, which had remained unopened since it was brought there. The whole of these papers were rearranged by the late Duke, with the assistance of the editor, (then librarian at Stowe,) but with the ducal wish that they should not be published before the death of his uncle, the Right Hon. Thomas Grenville. The latter, however, surviving the Duke seven years, the publication was retarded till, by the present Duke, it was committed to the hands of the editor, in conformity with the intention of his father. In England in the last century there were _castes_ as marked as in India: there was a military caste, a class of society in which the generality of the military commissions, and all the leading employments of the court, went; there was also a political _caste_, a class in which all the great offices of administration went, as regularly as the night succeeded the day, and in which any deviation from the routine, any appointment of any individual _not_ in the muster-roll of the aristocracy, would probably have been considered as a deviation from the law of nature. In this condition of things, men of other classes had no imaginable chance of prominent office on their own account. Their only hope must be in attaching themselves to some of those "_Dii majorum gentium_"--those sons of fortune, those hereditary possessors of high positions, those natural rulers of the powers and the privileges of political high life. The government, in consequence, was an Oligarchy under the name of a monarchy, and the authority of the Crown was merged in the actual authority of the political connection.
