_June 18._--A walk in North Salem in the decline of yesterday afternoon,--beautiful weather, bright, sunny, with a western or northwestern wind just cool enough, and a slight superfluity of heat. The verdure, both of trees and grass, is now in its prime, the leaves elastic, all life. The grass-fields are plenteously bestrewn with white-weed, large spaces looking as white as a sheet of snow, at a distance, yet with an indescribably warmer tinge than snow,--living white, intermixed with living green. The hills and hollows beyond the Cold Spring copiously shaded, principally with oaks of good growth, and some walnut-trees, with the rich sun brightening in the midst of the open spaces, and mellowing and fading into the shade,--and single trees, with their cool spot of shade in the waste of sun: quite a picture of beauty, gently picturesque. The surface of the land is so varied, with woodland mingled, that the eye cannot reach far away, except now and then in vistas perhaps across the river, showing houses, or a church and surrounding village, in Upper Beverly. In one of the sunny bits of pasture, walled irregularly in with oak-shade, I saw a gray mare feeding, and, as I drew near, a colt sprang up from amid the grass,--a very small colt. He looked me in the face, and I tried to startle him, so as to make him gallop; but he stretched his long legs, one after another, walked quietly to his mother, and began to suck,--just wetting his lips, not being very hungry. Then he rubbed his head, alternately, with each hind leg. He was a graceful little beast. I bathed in the cove, overhung with maples and walnuts, the water cool and thrilling. At a distance it sparkled bright and blue in the breeze and sun. There were jelly-fish swimming about, and several left to melt away on the shore. On the shore, sprouting amongst the sand and gravel, I found samphire, growing somewhat like asparagus. It is an excellent salad at this season, salt, yet with an herb-like vivacity, and very tender. I strolled slowly through the pastures, watching my long shadow making grave, fantastic gestures in the sun. It is a pretty sight to see the sunshine brightening the entrance of a road which shortly becomes deeply overshadowed by trees on both sides. At the Cold Spring, three little girls, from six to nine, were seated on the stones in which the fountain is set, and paddling in the water. It was a pretty picture, and would have been prettier, if they had shown bare little legs, instead of pantalets. Very large trees overhung them, and the sun was so nearly gone down that a pleasant gloom made the spot sombre, in contrast with these light and laughing little figures. On perceiving me, they rose up, tittering among themselves. It seemed that there was a sort of playful malice in those who first saw me; for they allowed the other to keep on paddling, without warning her of my approach. I passed along, and heard them come chattering behind.
