The collection is enriched by a letter dated "Cambridge, August 26, 1775" from Washington himself. He wrote it in that house,--now so venerable with his memory,--in that very room, where his bust now stands upon a poet's table; from this sheet of paper passed the hand that held the leading-staff! Nothing can be more perfectly in keeping with all other manifestations of Washington than the whole visible aspect and embodiment of this letter. The manuscript is as clear as daylight; the punctuation exact, to a comma. There is a calm accuracy throughout, which seems the production of a species of intelligence that cannot err, and which, if we may so speak, would affect us with a more human warmth, if we could conceive it capable of some slight human error. The chirography is characterized by a plain and easy grace, which, in the signature, is somewhat elaborated, and becomes a type of the personal manner of a gentleman of the old school, but without detriment to the truth and clearness that distinguish the rest of the manuscript. The lines are as straight and equidistant as if ruled; and from beginning to end, there is no physical symptom--as how should there be?--of a varying mood, of jets of emotion, or any of those fluctuating feelings that pass from the hearts into the fingers of common men. The paper itself (like most of those Revolutionary letters, which are written on fabrics fit to endure the burden of ponderous and earnest thought) is stout, and of excellent quality, and bears the water-mark of Britannia, surmounted by the Crown. The subject of the letter is a statement of reasons for not taking possession of Point Alderton; a position commanding the entrance of Boston Harbor. After explaining the difficulties of the case, arising from his want of men and munitions for the adequate defence of the lines which he already occupies, Washington proceeds: "To you, sir, who are a well-wisher to the cause, and can reason upon the effects of such conduct, I may open myself with freedom, because no improper disclosures will be made of our situation. But I cannot expose my weakness to the enemy (though I believe they are pretty well informed of everything that passes), by telling this and that man, who are daily pointing out this, and that, and t' other place, of all the motives that govern my actions; notwithstanding I know what will be the consequence of not doing it,--namely, that I shall be accused of inattention to the public service, and perhaps of want of spirit to prosecute it. But this shall have no effect upon my conduct. I will steadily (as far as my judgment will assist me) pursue such measures as I think conducive to the interest of the cause, and rest satisfied under any obloquy that shall be thrown, conscious of having discharged my duty to the best of my abilities."
