Returned by Caithness to Parliament, in which he remained for thirty years, rarely missing a division, his position gave him farther opportunities of usefulness, which he did not neglect to employ. Mr. Pitt, observing his persevering energy in all useful public projects, sent for him to Downing Street, and voluntarily proposed his assistance in any object he might have in view. Another man might have thought of himself and his own promotion; but Sir John characteristically replied, that he desired no favour for himself, but intimated that the reward most gratifying to his feelings would be Mr. Pitt’s assistance in the establishment of a National Board of Agriculture. Arthur Young laid a bet with the baronet that his scheme would never be established, adding, “Your Board of Agriculture will be in the moon!” But vigorously setting to work, he roused public attention to the subject, enlisted a majority of Parliament on his side, and eventually established the Board, of which he was appointed President. The result of its action need not be described, but the stimulus which it gave to agriculture and stock-raising was shortly felt throughout the whole United Kingdom, and tens of thousands of acres were redeemed from barrenness by its operation. He was equally indefatigable in encouraging the establishment of fisheries; and the successful founding of these great branches of British industry at Thurso and Wick was mainly due to his exertions. He urged for long years, and at length succeeded in obtaining the enclosure of a harbour for the latter place, which is perhaps the greatest and most prosperous fishing town in the world.
