of Mexico after his triumphant campaign, inclosing a memorandum which he urged the general to hand to civilians attached to the army. This was a request to purchase books, copies of documents, printed grammars, and vocabularies of the Mexican languages, and he authorized the general to spend four hundred dollars in this purpose on his account. In the second volume, published in 1848, he printed the result of his continued investigations on the subject which first interested him, as an introduction to a republication of a work by Mr. Hale on the "Indians of Northwest America." This consisted of geographical notices, an account of Indian means of subsistence, the ancient semi-civilization of the Northwest, Indian philology, and analogic comparisons with the Chinese and Polynesian languages. These papers Mr. Gallatin modestly described to Chevalier as the 'fruits of his leisure,' and to Sismondi he wrote that he had not the requisite talent for success in literature or science. They nevertheless entitle him to the honorable name of the Father of American Ethnography. In 1837 Mr. Wheaton, the American minister at Berlin, requested Mr. Gallatin to put the Baron von Humboldt in possession of authentic data concerning the production of gold in the United States. Humboldt had visited the Oural and Siberian regions in 1829, at the request of the Emperor of Russia, to make investigations as to their production of the precious metals. Mr. Gallatin was the only authority in the United States on the subject. Later von Humboldt wrote to Mr. Gallatin of the interest felt abroad, and by himself, in the gold of the mountains of Virginia and Tennessee, a country which rivaled on a small scale the Dorado of Siberia. The treasures of the Pacific coast were not yet dreamed of. Mr. Gallatin perfectly understood the range of his own powers. He said of himself:-- "If I have met with any success, either in public bodies, as an executive officer, or in foreign negotiations, it has been exclusively through a patient and most thorough investigation of all the attainable facts, and a cautious application of these to the questions under discussion.... Long habit has given me great facility in collating, digesting, and extracting complex documents, but I am not hasty in drawing inferences; the arrangement of the facts and arguments is always to me a considerable labor, and though aiming at nothing more than perspicuity and brevity, I am a very slow writer."
