On the whole, this third year of the Administration closed not less satisfactorily than its predecessors, and Congress adjourned without anxiety after carrying into effect all the measures which Mr. Gallatin had at heart. So far as he was concerned, hardly a lisp of discontent was heard, except, perhaps, among the followers of Duane and Leib. By them he was accused of wishing to build up a third party by the patronage of the Treasury, a charge which meant only that he had refused to put his patronage at their disposal. The summer again found Mr. Gallatin at Washington, alone, discontented, and occupied only with the details of Treasury work. One pleasure indeed he had, and as his acquaintance with Alexander Baring was destined to have no little value to him in future life, so his acquaintance of this summer with Alexander von Humboldt was turned to good account in after-years. In a letter to his wife he gave an amusing account of his first impressions of Humboldt. Among his correspondents of this year there are none whose letters seem to have any permanent value, unless one by John Randolph be an exception. In this there are curious suggestions of restlessness under the sense of political inferiority. It would be interesting to know what that opinion of Mr. Gallatin's was which could induce Randolph to concur with it so far as to favor the creation of a navy to blow the British cruisers out of water. GALLATIN TO HIS WIFE. DATE WASHINGTON, 6th June, 1804. ... I have received an exquisite intellectual treat from Baron Humboldt, the Prussian traveller, who is on his return from Peru and Mexico, where he travelled five years, and from which he has brought a mass of natural, philosophical, and political information which will render the geography, productions, and statistics of that country better known than those of most European countries. We all consider him as a very extraordinary man, and his travels, which he intends publishing on his return to Europe, will, I think, rank above any other production of the kind. I am not apt to be easily pleased, and he was not particularly prepossessing to my taste, for he speaks more than Lucas, Finley, and myself put together, and twice as fast as anybody I know, German, French, Spanish, and English, all together. But I was really delighted, and swallowed more information of various kinds in less than two hours than I had for two years past in all I had read or heard. He does not seem much above thirty, gives you no trouble in talking yourself, for he catches with perfect precision the idea you mean to convey before you have uttered the third word of your sentence, and, exclusively of his travelled acquirements, the extent of his reading and scientific knowledge is astonishing. I must acknowledge, in order to account for my enthusiasm, that he was surrounded with maps, statements, &c., all new to me, and several of which he has liberally permitted us to transcribe.
