It is amusing to an intelligent man who has much intercourse with our landholders and farmers, to note how little the most of them know of the prodigious forest wealth with which they are surrounded, even on the soil owned by themselves. Go to a man living in our middle and western states, and ask him how many varieties of wood grow upon his estate, and he Will, in all honesty, tell you that he has perhaps a dozen altogether, and these comprise such as he makes into his ox yokes, whippletrees, sled crooks, hoops, handspikes, withes, whip-stocks, framing timber, boards, rails, fence posts, and fire wood; and if there be any more varieties than these, they might as well grow at the north pole as on his own territory, so far as any interest which he takes in them is concerned. Now, it appears that this little penisula of forty acres, on examination, produces sixty species of native woods! What a wealth of tree vegetation on so small a spot! And yet, this piece of ground is sterile, compared with many of -equal territory to be found in the United States.

"O! would some power the giftic gic to, To see ourselves ss ithers see us," in the wealth of our extensive and luxuriant forests! Bar tram, Michaux, and Nutlall, with all their research, have not revealed the extent of our woodland treasures, and there is yet a wide and a new field for the naturalist unexplained in the vast solitudes of Oregon, New Mexico, and the Californias. Even the bleaker and inhospitable shores of Lake Superior abound in woods new to our books, which may yet reveal to us productions of surpassing interest. It is gratifying to see, now and then, in your columns, our attention directed to such rich and refreshing subjects.

WE were much impressed by a little incident in our neighborhood last summer - showing, 1st, our wealth of forest trees, and 2d, how much more interest foreigners take in them, than natives. A student in the School of Aunts, in Paris, wished to procure a collection of samples of the different American woods - showing their structure, grain, Ac. A gentleman in our neighborhood, owning a beautiful peninsula of 40 acres on the Hudson - Mr. Denning, undertook to procure them for him. Sixty species he found on his own place, almost as many indigenous trees as could be found in any one country in Europe. The remainder, making 107 species, he collected without difficulty. So few persons are aware of the great variety embraced in our forests, that we have asked Mr. D. for the list, for preservation in our columns. Ed.

Dear Sir - Having been requested by Mr. Pea body, of Salem, to procure for him specimens of American woods, to be forwarded to a Scientific Institution in France, I found in our immediate vicinity 107 varieties, some few of which were brought from the south, but most of them are natives of our own soil. I have taken the nomenclature of Browne's Sylva Americana, giving also the common name, and some have only the name they are known by in the country. The first sixty varieties I found on this place; the residue in the mountains in Putnam county. Knowing your great affection for trees, I send you a list of the specimens furnished Mr. Peabody. Previous to completing the collection, I became very much interested in it, and quite surprised to find so many varieties in our own vicinity. Our mountain wood-cutters take much pride in their knowledge of the different species of wood, and I remarked how very accurate they were in distinguishing varieties in which the difference is not very apparent. I added some specimens not included in the list, which did not reach the size of trees, as I included none under sixteen feet.

Yours truly, W. H. Denning.
