[13] The following is a list of the principal mines worked under the Spanish government, with their situation:
| Mine La Motte | Head of St. Francis river. |
| Mine à Joe | On Flat river. |
| Mine à Burton | On a branch of Mineral Fork. |
| Old Mines | On a branch of Mineral Fork. |
| Renault's Mines | On Mineral Fork, or Fourche Arno. |
[14] A law erecting the Territory of Arkansas from the southern part of Missouri, has since passed; but its northern boundary is extended so as to include all White river above the latitude of 36° 30'.

[16] On this passage, Mr. Silliman remarks, "that sulphur is not poisonous to men or animals.... The carbonate of barytes is eminently poisonous; but we have never heard that the sulphate is so. May not the licking around the furnaces expose the cattle to receive lead, in some of its forms, minutely divided? or, if it be not active in the metallic state, both the oxide and the carbonate, which must of course exist around the furnaces, would be highly active and poisonous. Is it not possible, also, that some of the natural waters of the country may, in consequence of saline or acid impregnations, dissolve some of the lead, and thus obtain saturnine qualities? We must allow, however, that we are not acquainted with the existence of any natural water thus impregnated."—Jour. Sci., Vol. III.
[17] I was mistaken in supposing this the only locality of the fluate of lime in the United States. It has also been found "in Virginia, near Woodstock or Miller's town, Shenandoah county, in small loose masses, in the fissures of a limestone containing shells. (Barton.)—In Maryland, on the west side of the Blue Ridge, with sulphate of barytes. (Hayden.)—In New Jersey, near Franklin Furnace, in Sussex county, disseminated in lamellar carbonate of lime, and accompanied with mica and carburet of iron; also near Hamburg, in the same county, on the turnpike to Pompton, in a vein of quartz and feldspar. (Bruce.)—In New York, near Saratoga Springs, in limestone; it is nearly colorless, and penetrated by pyrites.—In Vermont, at Thetford.—In Connecticut, at Middletown, in a vein, and is accompanied by sulphurets of lead, zinc, and iron. (Bruce.)—In Massachusetts, at the lead-mine in Southampton, where it is imbedded in sulphate of barytes, or granite; its colors are green, purple, &c.—In New Hampshire, at Rosebrook's Gap, in the White Mountains, in small detached pieces. (Gibbs.)"—Cleveland's Mineralogy.
