Not satisfied with detracting from the merits of Mr.Schoolcraft's work, 'Trio' indulges in some bitter and illiberal remarks upon those gentlemen who composed the Yellow Stone River expedition; and to show how little qualified he is for the subject, I will venture to declare him ignorant of the very first principles upon which that expedition was organized." So much for the "Trio." No actual discovery of the authors was made; but from information subsequently obtained, it is believed that their names are denoted under the anagram LENICTRA.
Other criticisms of a different stamp were, however, received from high sources, speaking well of the work, which may here be mentioned.
Professor Silliman writes from New Haven, November 22d: "I perused your travels with great satisfaction; they have imparted to me a great deal of information and pleasure.

Could any scientific friend of yours (Captain Douglass, for instance) prepare a notice, or a review, I would cheerfully insert it.
"In reading your travels, I marked with a pencil the scientific notices, and especially those on mineralogy and geology, thinking that I might at a future period embody them into an article for the journal.

Would it not be consistent with your time and occupations to do this, and forward me the article?
I would be greatly pleased also to receive from you a notice of the fluor spar from Illinois; of the fossil tree; and, in short, any of your scientific or miscellaneous observations, which you may see fit to intrust to the pages of the journal, I shall be happy to receive, and trust they would not have a disadvantageous introduction to the world." How different is this in its spirit and temper from the flimsy thoughts of the Trio! _Literary Honors_ .-- Dr.Alfred S.Monson, of New Haven, informs me (November 23d) of my election as a member of the American Geological Society.

Mr.Austin Abbott communicates notice of my election as a member of the Hudson Lyceum of Natural History.
_Appointment under Government_ .-- A friend in high confidence at Washington writes (November 4th): "The proposition to remove from Sackett's Harbor to the Sault of St.Mary a battalion of the army, and to establish a military post at the latter place, has been submitted by Mr.Calhoun to the President.

The pressure of other subjects has required an investigation and decision since his return; so that he has not yet been able to examine this matter.
