On the morning of the 13th of December, 1799, the General was engaged in making some improvements in the front of Mount Vernon. As was usual with him, he carried his own compass, noted his observations, and marked out the ground. The day became rainy, with sleet, and the improver remained so long exposed to the inclemency of the weather as to be considerably wetted before his return to the house. About one o'clock he was seized with chilliness and nausea, but having changed his clothes, he sat down to his indoor work. At night, on joining his family circle, he complained of a slight indisposition. Upon the night of the following day, having borne acute suffering with composure and fortitude, he died. In person Washington was unique. He looked like no one else. To a stature lofty and commanding he united a form of the manliest proportions, and a dignified, graceful, and imposing carriage. In the prime of life he stood six feet, two inches. From the period of the Revolution there was an evident bending in his frame so passing straight before, but the stoop came from the cares and toils of that arduous contest rather than from years. For his step was firm, his appearance noble and impressive long after the time when the physical properties of men are supposed to wane. A majestic height was met by corresponding breadth and firmness. His whole person was so cast in nature's finest mould as to resemble an ancient statue, all of whose parts unite to the perfection of the whole. But with all its development of muscular power, Washington's form had no look of bulkiness, and so harmonious were its proportions that he did not appear so tall as his portraits have represented. He was rather spare than full during his whole life. The strength of Washington's arm was shown on several occasions. He threw a stone from the bed of the stream to the top of the Natural Bridge, Virginia, and another stone across the Rappahannock at Fredericksburg. The stone was said to be a piece of slate about the size of a dollar with which he spanned the bold river, and it took the ground at least thirty yards on the other side. Many have since tried this feat, but none have cleared the water.
