New York is now an immense city. Strangers are received here with less reserve generally than at Philadelphia. I found the Academy well supplied with paintings, and sculptures of the Greek masters. The steam boats of the Sweet Ohio, with all their swiftness of motion and beautiful forms, do not interest the eye like those that are here tossing over the foaming billows with the grace of the wild swan. Were I a painter—ah could I, like ——, carry in my mind's eye all my mind feels when looking at the Battery at the moon's tender reflections on the farthest sails, forcing the vessel they move with the very wind's heart,—express as he does the quick moving tar hauling in a reef at the yard's end,—and make on the canvas a noble commander speak, as you have done; then, my dear friend, I could show you New York's harbor and all its beauties.... I cannot part with that Fair City [Philadelphia] this soon; I cannot help thanking Fairman, Peale, Neagle, Le Sueur, and many others besides Mc Murty for their attentions to me. Should you see honest Quaker Haines, beg him to believe me his friend; should you see Mr. Ord, tell him I never was his enemy. Think of me some time, and accept the truest best wishes of JOHN J. AUDUBON. I leave for Boston tomorrow. Should you please to write to me, direct to Care of Messrs. Anshutz & Co, Pittsburgh, where I shall be in about 40 days.
