In the midst of this prosperous career the two brothers-in-law, the Ministers, began to differ in their views, and Lord Townshend was soon driven by the overbearing conduct of Walpole to resign. Lady Townshend, the sister of Walpole, and even Queen Caroline, exerted their influence for some time to put an end to these feuds; but Lady Townshend soon died, and the queen, finding the breach inevitable, took the side of Walpole as the more indispensable servant of the Crown. There were serious topics on which Townshend and Walpole differed, both domestic and foreign. Townshend did not approve of the length to which matters were carried against the Emperor, and he was weary of the timid temper of the Duke of Newcastle, and strongly urged his dismissal, and the employment of Lord Chesterfield in his place; but a Pension Bill brought the quarrel to a crisis. The object of the Bill, which was warmly supported by the Opposition, was to prevent any man holding a pension, or who had any office held in trust for him, from sitting in Parliament. The king privately styled it "a villainous Bill, which ought to be torn to pieces in every particular." Both Walpole and Townshend were of the same opinion; but Townshend was for openly opposing it, Walpole for letting it pass the Commons, and be thrown out in the Lords. Townshend, to whom the odium of rejecting it was thus carried in the Lords, protested against this disingenuous conduct on the part of Walpole, and assured him that the trick would soon be fully observed, and bring more unpopularity on him in the end than a manly, open opposition--which it did. The temper of Townshend was warm, though his nature was upright; and in this mood, a discussion taking place on foreign affairs at the house of Colonel Selwyn, the dispute became so heated that Walpole declared that he did not believe what Townshend was saying. The indignant Townshend seized Walpole by the collar, and they both grasped their swords. Mrs. Selwyn shrieked for assistance, and the incensed relatives were parted; but they never could be reconciled, and, after making another effort to obtain the dismissal of Newcastle, and to maintain his own position against the overbearing Walpole, Townshend resigned on the 16th of May. He retired to Reynham, and passed the remainder of his life in rural pursuits. One of the greatest benefits which he conferred on this country he conferred after his retirement--that of introducing the turnip from Germany.
