[Schoolcraft.] Also on the banks of Bonne Femme, near New Franklin. [Compiler.]

Argillaceous slate.-It is found overlaying shale on the Missouri, at La Charbonnière, six miles below St. Charles.-[Dr. Beck.] Also fifteen miles south of Lexington, in Lafayette county.-[Compiler.]

Shale. On the Missouri, under the above. It rests upon coal, and sometimes alternates with it.—[Dr. Beck.]

Potters' clay. On the right bank of the Mississippi, commencing at the head of Tywapety bottom, about forty miles above the junction of the Ohio, and extending for thirty-four miles to nearly six miles above the Grand Tower. The stratum varies in thickness from one to ten feet, rests on sandstone, and is covered by shell limestone, containing well-characterized nodules and veins of flint.-[Jessup and Cleveland.] Also at Gray's mine, in Jefferson county, ten feet below the surface of the ground, snow-white, unctuous, becomes plastic by mixture with water, and is infusible in a very high heat.-[Schoolcraft.]

Fullers' earth.-On the banks of the Mississippi river, at Tywapety and Bois brulé bottoms, and also near Ste. Genevieve.[Schoolcraft.]

Reddle-red chalk.-This mineral occurs in a bed of considerable extent in Washington county.-[Schoolcraft.]

Sulphur.-Several springs in the vicinity of Herculaneum are highly impregnated with this mineral. It is deposited on the stones over which the water runs in the form of a yellowish crust. This is also the case at the spring five miles west of St. Louis. -[Dr. Beck.]

Graphite.-In Madison and Washington counties. It occurs in lamina and nodules, disseminated in iron ore.—[Dr. Beck.]

Coal. At Florisant, eighteen miles north of St. Louis, and on the Osage river.-[Schoolcraft.] At La Charbonnière, on the Missouri river.-[Dr. Beck.] On Rivière des Pères, in St. Louis, Howard, Cooper, Boone, Monroe, Saline, Lafayette, and almost all the counties of the state.-[Compiler.]

Sulphuret of iron-iron pyrites.-On the branches of the Merrimac, and at several mines in Washington county; crystal

lized, and in lamellar masses, sometimes interspersed with blende, heavy spar, and galena.-[Schoolcraft.] Also in Pike county, near Louisiana, in globular masses, which are sometimes radiated. [Dr. Beck.]

Micaceous oxyde of iron.-At the Narrows, Madison county, a vein of this ore is found traversing red granite.-[Schoolcraft.] Compact red oxyde of iron.-On the head waters of Gasconade river. [Schoolcraft.]

Ochrey red oxyde of iron-red ochre.-In Cape Girardeau county, six miles west of the Mississippi river.—[Schoolcraft.]

Sulphuret of lead-galena.—In the counties of Washington, Ste. Genevieve, St. François, Madison, and Jefferson. Also at St. Louis, and in the vicinity of St. Charles, and on the head waters of the Osage river.-[Jessup.]

Carbonate of lead.-In Missouri, at Mine à Breton. In this situation it is frequently found incrusting galena.-[Schoolcraft.] Sulphuret of zinc-blende.-This mineral is found associated with sulphuret of lead at the mines in Washington, Jefferson, and St. François counties.-[Dr. Beck.]

Oxyde of manganese.-Near the head of the Merrimac river, accompanying ores of iron.-[Schoolcraft.]

Sulphuret of antimony.-Specimens of this mineral have been found in Washington county.-[Schoolcraft.]

REMARKS.

; and

The census is supposed to have been loosely or inaccurately taken. The time given for this operation, and the slender compensation allowed the sheriffs, would have a tendency to such a result. The emigrants who arrived in the autumn of 1836 generally came too late to be included in the enumeration the emigration of this year is known to be far greater than that of any previous year since the adoption of the constitution of Missouri. Many intelligent citizens of the state compute the present population of Missouri at one hundred thousand more than the above table exhibits :

There are in Missouri 40,540 slaves, and

911 free blacks.

The slave population has not increased as rapidly as that of the white.

In the foregoing table, showing the increase of the population of counties, the number of inhabitants in some of them appears to have been reduced. This is caused by cutting off inhabited territory from the counties to make new ones.
