On the margin of this village, is a curious agricultural exhibition. It is a large tract of flat land upon Connecticut river, of great fertility and value (one hundred and fifty or two hundred dollars an acre,) containing altogether several thousand acres. With one or two trifling exceptions, it has no houses or dividing fences upon it, though partitioned among perhaps two hundred proprietors. Hardly an opulent, or _middling_ wealthy man in Northampton, but owns a lot of five, ten, twenty, or fifty acres, in this teeming expanse. The lots are all in crops, of one kind or other; and being mostly of regular shapes (oblongs, or other four sided figures,) the various aspects they present, accordingly as the crop happens to be deep green, light green, or yellow--mown, or unmown--afford a singular and rich treat, to an eye that can at once survey the whole. Most opportunely, Mount Holyoke (the great lion of western Massachusetts, to scenery-hunters,) furnishes the very stand, whence not only this lovely plain is seen, but the river, its valley, and the adjacent country, for twenty or thirty miles around. Nearly a thousand feet below you, and not quite a mile from the foot of the mountain, the low ground, fantastically chequered into lots so variously sized and colored--dwindling too, by the distance, into miniatures of themselves--reminds you of a gay bed-quilt. A lady of our party (we ascended the mountain this afternoon, and staid till after sunset,) aptly compared it to a Yankee _comfort_; the elms and fruit trees dotted over the surface, and shrunk and softened in the distance, representing the tufts of wool which besprinkle that appropriately named article of furniture. The whole landscape, seen from Mount Holyoke, it would be presumptuous in me to try to describe. I have said, twenty or thirty miles around: but in one direction, we see, in clear weather, the East and West Rocks, near New Haven--about seventy miles off. Fourteen villages are within view. The whole scene is panoramic: it is as vivid and distinct as reality; but rich, soft and mellow, as a picture. We descended; and as we recrossed the river by twilight, the red gleams from the western sky, reflected in long lines from the dimpling water, forced upon more than one mind that fine passage in a late work of fiction, where the remark, that "no man can judge of the happiness of another," is illustrated by the reflection of moon-beams from a lake. But I am growing lack-a-daisical: and must conclude. I set off in the stage for Albany, at two o'clock in the morning. Good night. We copy the following production of Mrs. Sigourney from the "_American Annuals of Education and Instruction_," a periodical published in Boston. It is difficult to decide whether the prose or poetry of this distinguished lady is entitled to preference. Her noble efforts in behalf of her own sex deserve their gratitude and our admiration.
