The following communication is dated Mogadon, Summit Co., Ohio, July 10, 1855. Editor of the Horticulturist - I see in the last issue of your work a notice of the " Wellingtonia Gigantea" of California. It is spoken of as a discovery of Mr. William Lobb. Now what entitles a man to the appellation of "Discoverer" I am not prepared to determine. But the trees spoken of are as familiar to many residents of California, as any other tree in that State.

There are many statements of Mr. Lobb, not at all in accordance with facts. He says:. "It inhabits a solitary district on the elevated slopes of the Siera Nevada, near the head waters of the Stanislau and San Antonia rivers".

So far as I know from a residence of some time on the western slope of the Sieras, and inquiries of others - the spot designated is the only one on the 8ieras, where they Are to be found. But the home of the tree, and where they are to be found in great numbers, is on the western slope of the coast range of the mountains. They are found scattered over an extent of country, for more than two hundred miles north of San Francisco. On Eel river, and the Klamath, they exist in great numbers and much larger than those described by Mr. Lobb, on the Stanislau. They are found there thirty feet in diameter. A company of men cut one down (a small one), for a bridge; it was fallen across an impassable stream. It formed a bridge on which three mules packed could cross abreast, and was of sufficient width for a wagon bridge. The Indians frequently cut into them through the sap, and by burning excavate a hole large enough for a large family. A gentleman in whose word I hare the most implicit confidence, said a party of seven men slept in one and that he turned a pole fifteen feet around in the hollow as high as his head horizontally, and this was one of the smallest sized trees.

But sir, I will not tell what I have the best reason to believe, and know to be the truth about the sue of some of these monarchs of the forest. The great object of my writing, is to enter a remonstrance to the name given by the "John Bull" whom you recognise as the discoverer. The tree has been for two years known by the name you suggest "Washingtonia Gigantea," in California. A year since, a computation of the amount of inch lumber in the largest tree that Lobb described, was made by a Yankee, and that was the name then given.

I protest against the alteration by any admirer of the "Iron Duke" or any other foreigner. Tours respectfully, M. Jewrtt.
