WASHINGTON IN PHILADELPHIA. [Two Original Letters from Washington, Contributed to Our Daily Fare.J BY BENSON J. LOSSING, Editor op Ouii Daily Fare I send you two unpublished letters of Gen. Washington'to Gen. Schuyler, now lying be fore me. They respectively, have a local in terest for us both, one having been written at Poughkeepsie, and the other at Philadelphia. The first of the subjoined letters was written ten days before the British evacuated the city of New York, at the close of the Revolution. Washington had received a verbal message from Silt Guy Carleton, on the Oth of No vember, at Rocky Ilill, New Jersey, announ cing his intention to withdraw his army from New York, as early as possible. At that time, a part of the Continental Army Avas at West Point, on the Hudson, under General Knox, and Washington proceeded to that post to make preparations for the evacuation. On the 14th of November he went from West Point to Poughkeepsie, twenty-four miles further up the Hudson, where George Clinton, the Go vernor of New York, had his official residence; and in consequence of the interview between these public officers on the evening of the 14tli, Clinton, on the following day issued a pro clamation, giving notice of the intended de parture of the British. On the same day, Washington wrote the subjoined letter : The second letter was written while Wash ington was on a visit to Philadelphia, a year before his death. At that, time, Avar with France was expected, and Washington had accepted the position of Commander-in-Chief of the Provisional Army then raised or about to be raised for the occasion, on the condition that General Alexander Hamilton (alluded to in the letter) should be the acting general-in chief in the field. At the time when he wrote the subjoined letter, he Avas in consultation Avith General Hamilton, Pinckney, and others, concerning the organization of the army. Poughkeepsie, June, 1804. [copy.] “ Poughkeepsie, 15tli Nov., 1783. Dear Sir: —lt gives me great pleasure to inform you that Sir Guy Carleton has an nounced to me his intention to relinquish the forts he holds on York Island from ICingsbridgc to McGavan’s Pass inclusive, on the 21st inst.; Herrick and Hampstead, Avith all to the east- Avard on Long Island on the same day, and, if possible, to give up the city, with Brooklyn, on the day following; and Paulus’ Hook, Den yces and Staten Island as soon afterward as practicable. “ From this disposition I have great hopes that in case no accident should happen, I shall have it in my potver to congratulate you on Otte ID .a. i Fabe. the full possession of this state by its Govern ment before the close of the present month. “ With the greatest esteem, I am, dear sir, Your most obe’t, humble servant, Geo. Washington. The best respects to Mrs. Schuyler and your fireside. Major-General Schuyler.” [copy.] Philadelphia, 4th Dec., 1798, My Dear Sir I have been honored with your letter of the 20th ult., and congratulate you, very sincerely, on the favorable change you have lately expe rienced (as I have been informed) in your health. “ 1 wish it may be perfectly restored. “I persuade myself, that it is unnecessary for me to add that, if health and other circum stances had enabled you and Mrs. Schuyler to have visited Mrs. Washington and myself, at Mount Yernon, it would have been considered as a most pleasing and flattering evidence of your regard; and the more so, as neither she nor I, ever expects to be more than twenty five miles from that retreat, during the rem nant of our lives. “But, strange to relate, here I am! buried in scenes far removed and foreign from any I had contemplated when I quitted the chair of Government. “Y'our grandson, Mr. Church, has all the exterior of a fine young man, and, from Avhat I have heard of his intellects and principles, will do justice to and reward the precepts he has received from yourself, his parents, and Uncle Hamilton. So far, then, as my atten tions to him will go, consistent with my other duties, he may surely count upon me. “I pray you to present me (and I am sure Mrs. IVashington would unite in them if she was here) to Mrs. Schuyler, in the most re spectful terms, and let me pray you to be as sured of the sincere esteem, regard, and wishes of the most affectionate kind, of “ Dear, sir, your most obedient and “ Very humble servant, “ G. Washington. “ Philip Schuyler, Esq.” A NOBLE TESTIMONIAL. The folloAving letter from a soldier tells “briefly and bravely” Avhat the Sanitary is Washington, D. C., April 4, 1804. Miss , Member of Ladies Executive Committee of Central Fair of Sanitary Com- For the past two months on arduous duty, and often compelled to seek shelter in the tents of the Sanitary Commission, I have often in tended to acknoAvledge my obligations to that organization through the press, but want of time, together Avith other causes, l)as as often prevented my doing so. And, to-day, acci dent, rather than anything else, prompts my acknowledgments, and to you. On duty at Alexandria, Va., engaged in distributing re cruits to the several armies noiv in the field, I have often found myself with detachments of men, Avhen night Avas falling around me, Avitli no place of shelter, and never yet have I ap plied to the Sanitary Commission in vain. The accommodations they provide are not—cannot be—excelled in the army, Avhile those in charge are always kind and obliging. Until the last bed is full, until the last blanket is exhausted, and the last vacant space on the floor is occu pied, no soldier, either sick or well, is turned aAvay. The amount of expense incurred is necessarily great, but the good done is more than proportionate. In no possible way can money for the alleviation of misery and suffer ing in the army be so well applied. I speak from my own experience, better than that of many others, from the fact that I have been, in the discharge of my duties, to every corps, and to nearly every division and brigade in the Army of the Potomac. More than the foregoing is deserved, less I could not say and be just. Your obedient servant, Williaji Austin, Ist Lt. Co. G, 107f/t K. I'. Vols. THE ART GALLERY. Among the most remarkable features of the Fair, the Art Gallery deserves special men tion. A single room, four hundred feet in length, is of itself a wonder; but Avhen we think of it as lined at the distance of from three to ten feet from the ground with excel lent pictures, it will be readily admitted that no exhibition of the kind was ever before Avitnessed in America. And these pictures are truly excellent, having been, notwithstand ng their vast number, carefully selected. Had the Committee on Art taken all which Avere available, they might have filled a gallery of twice the size of the present one. The best private collections from Boston to the Border have contributed their treasures, thanks to the Committee, aided by the indefatigable exertions of Messrs. Joseph Harrison and James L. Clagiiorn, who did all in their power to ascertain where the choicest pictures were to be found. This part of the Fair alone is in reality well worth far more than the price of admission. OUR HISTORY OF THE SANITARY FAIRS. We give on our leading page the first of a series of articles by Mr. Charles Stille, devoted to a history of the Sanitary Fairs which have been held in this country. We believe that we are guilty of no idle vaunt when Ave venture to commend these papers to our renders as one of the most valuable records of the domestic history of our Avar ever written.
