Upon the tributaries of the Kah-we-ah river, these trees are converted by the mills into lumber, which is sold about as cheap as pine. The lumber is much like the famous red-wood of California, and is equally durable, though perhaps not so easily worked. Although of the same genus as the red-wood, the _species_ is distinct, the “Big Trees” being known as the Sequoia Gigantea, while the California red-wood is known as the Sequoia Sempervirens. This statement may seem unnecessary to the botanist, but the two species are so frequently confounded in respectable eastern periodicals, that the statement here is deemed proper. Besides this, absurd fears have been expressed by those uninformed of the facility with which these trees have been cultivated in Europe and in this country, that the species will soon become extinct.[21] Professor Whitney says: “It is astonishing how little that is really reliable is to be found in all that has been published about big trees. No correct statement of their distribution or dimensions has appeared in print; and if their age has been correctly stated in one or two scientific journals, no such information ever finds its way into the popular descriptions of this tree, which are repeated over and over again in contributions to newspapers and in books of travel.... No other plant ever attracted so much attention or attained such a celebrity within so short a period.... Seed were first sent to Europe and to the Eastern States in 1853, and since that time immense numbers have found their way to market. They germinate readily, and it is probable that hundreds of thousands of the trees (millions it is said) are growing in different parts of the world from seed planted. They flourish with peculiar luxuriance in Great Britain, and grow with extraordinary rapidity.... The genus were named in honor of Sequoia or Sequoyah, a Cherokee Indian of mixed blood, better known as George Guess, who is supposed to have been born about 1770, and who lived in Wills Valley, in the extreme northeastern part of Alabama, among the Cherokees. He became known to the world by his invention of an alphabet and written language for his tribe.... The big tree is extremely limited in its range, even more so than its twin brother, the red-wood. The latter is strictly a coast-range or sea-board tree; the other, inland or exclusively limited to the Sierra. Both trees are also peculiarly Californian. A very few of the red-wood may be found just across the border in Oregon, but the big tree has never been found outside of California, and probably never will be.” In a note Prof. Whitney says:
