We were kindly received at Detroit by General and Mrs. Cass, who had invited us to be their guests, and pursued our way, without accident, to New York, where we arrived the day prior to the annual celebration of the Evacuation. New scenes and new situations here rapidly developed themselves. But before these are named, some letters that followed me from the Lake may be noticed.
B.F. Stickney, Esq., writes (October 15th) from the foot of the Miami of the Lakes (now Toledo): "Recently I have had brought to me a specimen of manganese, the bed of which is located about nine miles south-west of this. The quantity is represented to be very extensive."
I find that strontian is much more extensively interspersed through the rock formations of this region than I had heretofore conceived. At the foot of the rapids of this river, there are extensive strata of carbonate of lime, sufficiently charged with magnesia to destroy all vegetation, when converted to the state of quicklime; although Dr. Mitchell, in his "Notes to Phillips' Mineralogy," denies to magnesian carbonate of lime this quality. But I have tested it fully. I rather think the doctor's mistake must have arisen from a supposition that Mr. Phillips intended to say that the magnesia, when in combination with carbonate of lime, and in sitû, was destructive to vegetation.
Ohio and Erie Canal.--"A commissioner of the State of Ohio, with engineers, is taking levels, examining water-courses, and making estimates of cost, to ascertain the practicability of making a canal from Cincinnati up the valley of the Big Miami, and Loromier's creek, across the summit level, to the Auglaize and Miami of Lake Erie, to the level of the lake water. These surveys will give us much assistance in judging of the geological formations between the Lake and the Mississippi."
Geology.--"As an outline sketch, I should say that, from the rock basin of the Erie-sea to the Ohio River, by the way of Fort Wayne, there is a ridge, of about 200 feet elevation, of rock formation, all new floetz, with a covering of from ten to seventy feet of pulverulent earth. At the summit this layer is twenty feet. That the Miami and Wabash have cut their courses down to the rock, with only here and there a little sand and gravel upon its surface. As far as conjecture will go, for the levels of the strata on the Wabash and Miami, the same mineralogical characters are to be found in the strata, at the same elevation. This would be an important fact to be ascertained, by the levels accurately taken."
"I am pleased that you have not abated your usual industry in the pursuit of knowledge in the science of geology and mineralogy, first in magnitude and first in the order of nature."
Morals of Green Bay.--J.D. Doty, Esq., Judge of the District, reports (Oct. 15th) that the Grand Jury for Brown County, at the late special session of court, presented forty indictments! Most of these appear to have been petty affairs; but they denote a lax state of society.
John Johnston, Esq., writes (Oct. 30th): "Since the arrival of the mail, I have been the constant companion in thought of the great and good Lafayette, throughout his tour, or rather splendid procession as far as the account has reached us, and for which history has no parallel. Oh! how poor, how base, the adulation given by interested sycophants to kings and despots, compared to the warm affections of the grateful heart, and spontaneous bursts of admiration and affection from a great, free, and happy people."
Hooking Minerals.--L. Bull, now of Philadelphia, writes respecting the position of several boxes of minerals left in the Lyceum of Natural History, of New York, in 1822, which have, been sadly depredated on.
Plan of a Philosophical Work on the Indians.--General C. announces to me (Dec. 5th) that he has settled on a plan for bringing forward the results of his researches on the subject of the Indian tribes. The details of this appear to be well selected and arranged, and the experiment on the popular taste of readers, for as such the work is designed, cannot but be hailed by every one who has thought upon the subject. Few men have seen more of the Indians in peace and war. Nobody has made the original collections which he has, and I know of no man possessing the capacity of throwing around them so much literary attraction. It is only to be hoped that his courage will not fail him when he comes to the sticking point. It requires more courage on some minds to write a book than to face a cannon.
