Marbles and Limestones of Arkansas.™—This report, by T. 
C. Hopkins, represents Volume IV of the Annual Rept. of the Ark- 
ansas Geol. Surv. for 1893. Part I consists of an introductory chapter 
giving a general description of the marble area of the State, followed 
by a discussion of limestones in general, including their composition and 
origin, geological and geographical distribution, varieties and uses, and 
a detailed description of the different limestones of Arkansas. In part 
II the author states briefly the origin and uses of marble, gives a 
résumé of the marbles of United States and other countries, and de- 
scribes in detail those of Arkansas, giving especial attention to their 
use for building purposes. In order to make the work of practical 
value in establishing a marble industry in the State, two chapters are 
devoted to quarrying and the preparation of the stone. 
The text is illustrated by a number of good plates, and a set of six 
map sheets. `
