AND COAL-MEASURES OF MISSOURI. 137 
At Wayne City, the landing for Independence, a series of limestone benches, 
with intervening marlites and shaly beds, extend to the height of two hundred and 
sixty feet. (Section No. 19, M.) Near the lower bench of limestone, the Allorisma 
sulcaia was found, together with a small and probably undescribed species of Pro- 
ductus. The highest wall of limestone presents a glistening surface, caused by the 
reflection of minute facets of calcareous spar disseminated through the rock. The 
middle beds are more schistose than those either above or below them. 
Towards Liberty Landing, the ridges decline to about eighty or one hundred feet 
in height, where a wall of limestone, six to eight feet thick, is found at an elevation 
of from thirty to forty feet above the river. Thence the corresponding strata, gra- 
dually rising again, appear at Livingston and Sibley, or old Fort Osage, from fifteen 
to twenty feet higher in the ridges. At the latter point, the base of the section is 
composed of greenish, concretionary, argillaceous shale, and hard marlite covered by 
a bed of limestone, eight feet above the water-level, which is partly made up of 
well-preserved specimens of Cheetetes capillaris. (Section No. 18, M.) Near the 
mouth of Fishing River, and above Napoleon, the same fossil is abundant in a gray 
concretionary limestone, underlaid by sandstone, the position of which is shown on 
Section No. 17, M. An undescribed species of Nerita occurs also at this locality. 
The first workable bed of coal which I encountered in my descent of the Mis- 
sourl River, was at Wellington. It is from twelve to fourteen inches thick, and 
lies a few feet above the bed of the river, as shown on Section No. 16, M. 
At Camiden, on the opposite side of the river, nearly east of Wellington, a bed of 
coal has been exposed, fifteen feet above the river, corresponding probably to the 
Wellington bed. It is also found at several places on the Snei, south of the Mis- 
souri. 
The bed of gray limestone, which covers the principal coal-seam at Wellington, 
containing Cheetetes capillaris, occupies the same relative position over the coal at 
Lexington, but here it lies at a greater elevation above the river—fifty feet. (Sec- 
tion No. 15, M.) Iwas informed by the men working the Lexington coal, that 
another seam existed in the bed of the river, also overlaid by limestone. 
One to two miles below Lexington, the coal and Chetetes limestone are seen on 
the right bank of the river, forty-five feet above the water-level. The coal is here 
two feet thick, and rests on indurated slaty clay. 
At the bold promontory on the right shore, fourteen miles below Lexington, 
heavy beds of sandstone, from fifteen to twenty feet in thickness, extend down to 
the river. Three to four miles further down, at the next promontory, the sand- 
stone is more schistose, and only five feet thick, and rests on four feet of argilla- 
ceous shale, seen just above the margin of the river, partly concealed by blocks 
of limestone which have fallen from above, and which appear to be derived from 
two calcareous bands over the sandstone. (Section No. 14, M.) 
At Waverley, which lies between Mount Hope and the Great Pass, there is said 
to be coal in the bed of the river; this probably corresponds to the twenty-inch 
seam at Lexington. Salt has been obtained by the evaporation of springs of brine 
on the Salt Fork of Riviére la Mine, which heads within a few miles of the same 
place.
