June 20th.—On the "Mary Powell," enjoy'd everything beyond precedent. The delicious tender summer day, just warm enough—the constantly changing but ever beautiful panorama on both sides of the river—(went up near a hundred miles)—the high straight walls of the stony Palisades—beautiful Yonkers, and beautiful Irvington—the never-ending hills, mostly in rounded lines, swathed with verdure,—the distant turns, like great shoulders in blue veils—the frequent gray and brown of the tall-rising rocks—the river itself, now narrowing, now expanding—the white sails of the many sloops, yachts, &c., some near, some in the distance—the rapid succession of handsome villages and cities, (our boat is a swift traveler, and makes few stops)—the Race—picturesque West Point, and indeed all along—the costly and often turreted mansions forever showing in some cheery light color, through the woods—make up the scene.
