A dangerous illness brought Washington near the grave, during his first Presidential summer, and he is said never to have regained his full strength. In August his mother died, venerable for years and wisdom, and always honored by her son in a spirit that would have satisfied a Roman matron. She maintained her simple habits to the last, and is said never to have exhibited surprise or elation, at her son's greatest glory, or the highest honors that could be paid him. Her remains rest under an unfinished monument, near Fredericksburgh, Virginia. Of the wife of the illustrious Chief, it is often said that little is known, and there is felt almost a spite against her memory because she destroyed before her death every letter of her husband to herself, save only one, written when he accepted the post of Commander-in-Chief. But, to our thinking, one single letter of hers, written to Mrs. Warren, after the President's return from a tour through the eastern States, tells the whole story of her character and tastes, a story by no means discreditable to the choice of the wisest of mankind. Mr. Sparks gives the letter entire, as we would gladly do if it were admissible. We must, however, content ourselves with a few short extracts:-- "You know me well enough to believe that I am fond only of what comes from the heart. Under a conviction that the demonstrations of respect and affection to him originate in that source, I cannot deny that I have taken some interest and pleasure in them. The difficulties which presented themselves to view in his first entering upon the Presidency, seem thus to be in some measure surmounted. * * * I had little thought, when the war was finished, that any circumstances could possibly happen which would call the General into public life again. I had anticipated that from that moment we should be suffered to grow old together, in solitude and tranquillity. That was the first and dearest wish of my heart. I will not, however, contemplate with too much regret, disappointments that were inevitable, though his feelings and my own were in perfect unison with respect to our predilection for private life. Yet I cannot blame him for having acted according to his ideas of duty, in obeying the voice of his country. The consciousness of having attempted to do all the good in his power, and the pleasure of finding his fellow-citizens so well satisfied with the disinterestedness of his conduct, will doubtless be some compensation for the great sacrifice I know he has made. * * * With respect to myself, I sometimes think the arrangement is not quite as it ought to have been, that I, who had much rather be at home, should occupy a place with which a great many younger and gayer women would be extremely pleased. * * * I am still determined to be cheerful and happy, in whatever situation I may be; for I have learned from experience that the greater part of our happiness or misery depends on our dispositions and not on our circumstances.
