His idea of good cultivation in these years was to let his fields lie fallow at certain intervals, though he also made use of manure, marl, etc., and in 1772 tried the experiment of sowing two bushels of salt per acre upon fallow ground, dividing the plot up into strips eight feet in width and sowing the alternate strips in order that he might be able to determine results. He imported from England an improved Rotheran or patent plow, and, having noticed in an agricultural work mention of a machine capable of pulling up two or three hundred stumps per day, he expressed a desire for one, saying: "If the accounts are not greatly exaggerated, such powerful assistance must be of vast utility in many parts of this wooden country, where it is impossible for our force (and laborers are not to be hired here), between the finishing of one crop and preparations for another, to clear ground fast enough to afford the proper changes, either in the planting or farming business." These were his golden days. He was not so rich as he was later nor so famous, but he was strong and well and young, he had abundant friends, and his neighbors thought well enough of him to send him to the Burgesses and to make him a vestryman of old Pohick Church; if he felt the need of recreation he went fishing or fox-hunting or attended a horse race or played a game of cards with his friends, and he had few things to trouble him seriously. But fussy kings and ministers overseas were meddling with the liberties of subjects and were creating a situation out of which was to come a mighty burden--a burden so Atalantean that it would have frightened most men, but one that he was brave enough and strong enough to shoulder and with it march down to immortality. CHAPTER VIII CONSERVING THE SOIL The Revolution rudely interrupted Washington's farming experiments, and for eight long years he was so actively engaged in the grim business of checkmating Howe and Clinton and Cornwallis that he could give little time or thought to agriculture. For more than six years, in fact, he did not once set foot upon his beloved fields and heard of his crops, his servants and his live stock only from family visitors to his camps or through the pages of his manager's letters. Peace at last brought him release. He had left Mount Vernon a simple country gentleman; he came back to it one of the most famous men in the world. He wasted no time in contemplating his laurels, but at once threw himself with renewed enthusiasm into his old occupation. His observation of northern agriculture and conversations with other farmers had broadened his views and he was more than ever progressive. He was now thoroughly convinced of the great desirability of grass and stock for conserving the soil and he was also wide awake to the need of better tools and methods and wished to make his estate beautiful as well as useful.
