Another singular feature of Mr. Jefferson's acting, is, that he not only makes "Rip Van Winkle" an actual living personage, but the dog "Snyder" also. Although "Snyder" never puts in an appearance upon the stage, he is as important a _dramatis persona_ as any on the stage. I think I have a perfect conception of that dog "Snyder"--a long, lank, shaggy, ill favored, yellow cur, loving "Rip" with all his heart, hating "Mrs. Rip," a sworn friend of all the children in the village, one ear bitten off in an unpleasantness with "Nick Vedder's" mean bull dog, but with a big heart after all in his carcass, and a dog who would always take the part of a small dog in a quarrel with a bigger one. Jefferson succeeds in making "Snyder" an actual canine, although he is never visible to the eye; and when "Snyder" goes rattling down the hill, scared out of his senses by Hendrick Hudson's phantom crew, I acknowledge to a feeling of sadness for the poor beast who is "Rip's" only friend. Although Mr. Jefferson never makes a point of theatrical attitudes for mere effect, some of his poses are remarkably beautiful and artistic, especially that one as he stands shading his eyes with his hands, looking with amazement at the village of Falling Waters, after waking up from his sleep; also the careless way in which he sits upon the table in the first act, and the peculiar attitude in the chair when he is ordered from the house, to which I have already alluded. They are just such attitudes as a painter would choose to paint, or a sculptor to chisel. They are thoroughly artistic, and much of this is undoubtedly due to the fact that Mr. Jefferson has very excellent talent in, and knowledge of, the sculptor's art. Had he followed it as a profession he would undoubtedly have achieved an eminence quite as elevated as that which he enjoys in the dramatic world. If I have devoted considerable of this letter's space to Mr. Jefferson, it is because his "Rip Van Winkle" is a production of art worthy more than passing notice, in the presence of which, the gauze and tinsel of the spectacular drama seem very tawdry, and mock heroics of the sensational and romantic schools of action very false. He stands the only embodiment of the natural school of action--the only true school. Who will be the next to follow him, and assist to reform and restore the stage to its proper place as a great educator of the people and exponent of art? September 5, 1868. _AN AUTUMN REVERIE._ It seems only a little handful of days ago that I was writing you of the note of the little blue trumpeter, announcing from the bare boughs the advent of Spring, and now the Autumn is here. And holding the days in our hands like grains of sand, there was now and then a golden one which you and I would have kept; but, alas! they, too, slipped through our powerless fingers, and the gold in the sand was but a dream within a dream.
