Now and then, for the sake of a refreshing change, he would leave the wilderness behind him, with all its toils and dangers, and betake him to Greenway Court, the woodland home of old Lord Fairfax, with whom he had become a great favorite, and was ever a welcome guest. Here he would spend a few weeks in the most agreeable manner you can well imagine; for the old lord, being a man of some learning and extensive reading, had collected, in the course of a long life, a large library of the best and rarest books, from which, during these three years, George derived great pleasure and much valuable information. Besides this, a keener fox-hunter than this odd old bachelor was not to be found in all the Old Dominion; and, for the full enjoyment of this sport, he always kept a pack of hounds of the purest English blood. At the first peep of dawn, the cheerful notes of the hunter's horn, and the deep-mouthed baying of the fox-hounds, filling the neighboring woods with their lively din, would call our young surveyor from his slumbers to come and join in the sports of the morning. Waiting for no second summons, he would be up and out in a trice, and mounted by the side of the merry old lord; when, at a signal wound on the bugle, the whole party would dash away, pell-mell, helter-skelter, over the hills and through the woods, up the hills and down them again, across the brooks and along the winding river; hunters and horses hard on the heels of the hounds, hounds hard on the heels of poor Renard, and poor Renard cutting, cutting away for dear life. During the three years thus employed, George made his home at Mount Vernon, it being nearer and more convenient to his field of labor; but, as often as his business would permit, he would go on a visit to his mother at the old homestead on the Rappahannock, whither, as I should have told you before now, his father had removed when he was but three or four years old. These were precious opportunities, ever improved by him, of extending to her that aid in the management of her family affairs, which to receive from him was her greatest pleasure, as well as his truest delight to give. About this time, he formed a habit of writing down in a diary or day-book such facts and observations as seemed to him worthy of note, by which means he would be enabled to fix firmly in his mind whatever might prove of use to him at a future day. This is a most excellent habit; and I would earnestly advise all young persons, desirous of increasing their stock of knowledge, to form it as soon as they begin the study of grammar and can write a good round hand. The following is a specimen of this diary, written by him at the age of sixteen, as you will see by the date therein given:--
