Note 118 — TRAVELS IN THE INTERIOR OF NORTH AMERICA, IN THE YEARS 1832, 1833, AND 1834 (continued 4)

It is well known that the whole tract contains shell limestone. Mr. Lesueur has made important collections of this kind on the Tower Rock at Vicksburg, Natchez, and other places on the banks of the Mississippi, of part of which he has made descriptions and drawings. He has accurately stated the several strata, with the shells of animals and fishbones occurring in them. The shells are very friable when taken out of the rock—afterwards, and especially if washed in water, they are firmer. Mr. Lesueur has sent large collections of these things to France.—Maximilian.
