The slate region of Arkansas is confined to the central portion of the Ouachita Uplift and covers portions of Polk, Montgomery, Garland and Saline Counties, as shown on the accompanying map. All of the deposits which have been developed commercially lie in western Montgomery and eastern Polk Counties, as shown.

The subject of the Arkansas slates has been covered in the State Geological Survey report for 1909, "Slates in Arkansas," by A. H. Purdue, and the following is taken from it:

"Physical Tests. The following specimens were collected and submitted to the Structural Materials Testing Laboratories of the U. S. Geological Survey at Forest Park, St. Louis, for transverse pressure, absorption, and physical tests, and for chemical analyses. The results are herewith published.

Composition. "Slate may be defined as any rock that has the property of parting along parallel planes developed to such an extent that it may be split into thin plates with even surfaces. This property of parting is called cleavage.

"As to color, slate may be black, purple, red or green. Black slate, like black shale, owes its color to finely divided carbonaceous matter deposited with the shale from which the slate was derived; purple slate to a mixture of iron oxide, FeОs and chlorite; red slate to the presence of iron oxide; and green slate probably to the presence of a large amount of chlorite.

Uses. "Most of the slate quarried in Arkansas is sold for roofing, though a large amount is used for other purposes, such as floor

*Owing to the large amount of volatile organic material it is impossible to determine the ferrous oxide-consequently all iron has been assumed as being present in the lowest state and calculated as such.
