By 1793 the burden of the estate had become so heavy that Washington decided to rent all of it except the Mansion House Farm and accordingly he wrote to Arthur Young telling his desire in the hope that Englishmen might be found to take it over. One man, Parkinson, of whom more hereafter, came to America and looked at one of the farms, but decided not to rent it. Washington's elaborate description of his land in his letter to Young, with an accompanying map, forms one of our best sources of information regarding Mount Vernon, so that we may be grateful that he had the intention even though nothing came of it. The whole of Mount Vernon continued to be cultivated as before until the last year of his life when he rented Dogue Run Farm to his nephew, Lawrence Lewis.
As a public man he was anxious to improve the general state of American agriculture and in his last annual message to Congress recommended the establishment of a board of agriculture to collect and diffuse information and "by premiums and small pecuniary aids to encourage and assist a spirit of discovery and improvement." In this recommendation the example of the English Board of Agriculture and the influence of his friend Arthur Young are discernible. It would have been well for the country if Congress had heeded the advice, but public opinion was not then educated to the need of such a step and almost a century passed before anything of much importance was done by the national government to improve the state of American agriculture.
In farming as in politics Washington was no standpatter. Notwithstanding many discouragements, he could not be kept from trying new things, and he furnished his farms with every kind of improved tool and implement calculated to do better work. At his death he owned not only threshing machines and a Dutch fan, but a wheat drill, a corn drill, a machine for gathering clover seed and another for raking up wheat. Yet most of his countrymen remained content to drop corn by hand, to broadcast their wheat, to tread out their grain and otherwise to follow methods as old as the days of Abel for at least another half century.
He was the first American conservationist. He realized that man owes a duty to the future just as he owes a debt to the past. He deplored the already developing policy of robber exploitation by which our soil and forests have been despoiled, for he foresaw the bitter fruits which such a policy must produce, and indeed was already producing on the fields of Virginia. He was no misanthropic cynic to exclaim, "What has posterity ever done for us that we should concern ourselves for posterity?" His care for the lands of Mount Vernon was evidence of the God-given trait imbedded in the best of men to transmit unimpaired to future generations what has been handed down to them.
His agricultural career has its lessons for us, even though we should not do well to follow some of his methods. The lessons lie rather in his conception of farming as an honorable occupation capable of being put on a better and more scientific basis by the application of brains and intelligence; in his open-minded and progressive seeking after better ways. Many of his experiments failed, it is true, but for his time he was a great Farmer, just as he was a great Patriot, Soldier and Statesman. Patient, hard-working, methodical, willing to sacrifice his own interests to those of the general good, he was one of those men who have helped raise mankind from the level of the brute and his whole career reflects credit upon human nature.
Peace hath its victories no less renowned than war, and the picture of the American Cincinnatus striving as earnestly on the green fields of Mount Vernon as he did upon the scarlet ones of Monmouth and Brandywine, is one that the world can not afford to forget.
