210 CEMENT MATERIALS AND INDUSTRY. [bull. 24. 
The timber is short-leaf pine, post oak, scrub hickoiy, black-jacl 
and black gum, with an occasional white oak and holly. 
The town of Dekalb is near the east edge of the Lagrange formi 
tion. One and a half miles northeast of the town, on Sucarnoocl' 
Creek, is a bed of lignite 3 feet thick, which outcrops a few feet abo^ 
the bed of the creek. This bed has been opened up with a view i 
developing the vein. A level was run 20 feet into the hill and const 
erable lignite taken out. It was found to be of excellent quality, an 
was burned in the office of the chancery clerk, Mr. S. O. Bell, at Di 
kalb. The following analyses were made, No. 1 b}^ J. C. Long an 
No. 2 by R. T. Pittman.

The lignite is overlain by a bed of gray clay and this b} r stratif 
red, } T ellow, and white sand, with occasional bands of ferrugincj 
sandstone in the sand. On these hills there is a deposit of Lafaye 
that reaches in places a thickness of 20 feet, and in this there is c< 
siderable sandstone. 
The Lagrange around Dekalb — the eastern edge of the format 
and therefore made up of its basal beds — is a mass of unconsolida 
sand and sandy clay, which is easily eroded. The country is rou 
being cut up into deep ravines and narrow valleys. 
The hillsides, when properly taken care of, are fertile, and the 
cleared land has a fine growth of pine, poplar, white oak, and hickc 
Two and one-half miles east of Scooba, on the west bank of the cr 
shown on the map (PI. II), is the first outcrop of Selma chalk on 
Scooba and Gainesville road. 
A sample of limestone was taken from this outcrop by A. F. Cri 
and was analyzed by W. S. McNeil, in the laboratory of the Uni 
States Geological Survey, with the following result:
