We are greatly indebted to B. B. Bedding & Co., of the State Journal, Sacramento, California, for a package of seeds of value. Among them is one of the greatest vegetable curiosities, called the Sing, or Vegetable Chestnut, sold by almost every Chinese vender of edibles in Califor- . nia, and brought from China in a cooked state. It resembles the horns of a bull.

The editors say that they have found but one place where these odd nuts are sold uncooked, and these are so damaged by age and mould, that there is no possibility of making them grow.

The plant producing this nut is well known to botanists. It is the Chinese Trapa Wcomw - the word is abridged from calcitrapa, the Latin name of a dangerous instrument furnished with four spines, which was formerly used in war to impede the progress of cavalry. Both this and the T. nutans are aquatics; the nuts are farinaceous, and are esteemed nourishing and pectoral. The skin, with the spines, being removed, there is a white, sweet kernel within, somewhat like a chestnut. The natans are sold in the markets of Venice, under the name of Jesuits' nuts. They are also much eaten in Switzerland, and the South of France. Some of the canals at Versailles are covered with the plant. Pliny says that the Thracians made them into bread; and Thunberg states that the Seeds of the T. bicornis are commonly put into broth in Japan. The plant flourishes in a cistern in the stove, and was fruited in England, in 1815. It is cultivated, by the Chinese, in marshes, and is a favorite article of food, which accounts for its being common in the oriental shops of California Accompanying these curious water-chestnuts are specimens of an apparently new walnut, lately discovered in California, in appearance between our native walnut and the Madeira-nut. Mr. Redding brought from a distance suckers from some old stools, and has them growing at Sacramento. We shall pay every attention to our specimens, and endeavor to raise them.

The tree is recommended for shade and ornament. Other specimens were sent to the Patent Office, but no leaves or flowers having been received, we are unable to say more of it at present; it does not appear to be described either by Michaux or Nuttall Swift's Improved Lawk Mowing Machine, on the basis of "Shanks'*," we have lately seen at work, and we are free to say that its operation is perfect; it cuts, picks up the grass, and rolls at the same time; the cutting is even, and, after a few weeks, a lawn presents the appearance that it should always do, and soon acquires an even, firm sod.

It is one of the greatest labor-saving machines ever invented, and is getting generally diffused. Address H. N. Swift, Fishkill Landing, Dutchess County, New York.

Aunt Charlotte's Seedling Strawberry is in request; one correspondent having actually sent the large sum of ten cents! for some seeds! We do hope some of our readers suppose there are disinterested articles which are not disguised puffs, occasionally, at ieast, in the Horticulturist, The story; was not written to sell the plant - quite the contrary, for the excellent penman and amiable gentleman who wrote that article, is too happy whenever he can gratify a friend; he was amused, however, with the remittance, which is expended in stamps, to tell the writer as much!
