334 ANNUAL REPORT 
shipped several miles from Cornelia furnace, and a clay obtained near the 
plant. This company also owns its own coal lands; hence the fuel ques- 
tion is not a troublesome one. The laboratory facilities are generously 
provided for. As to shipping facilities, they could not be improved upon, 
and there are probably few cement works who can boast of as many con- 
nections with different railroads. This shows the wisdom of building 
the plant at this place instead of erecting it at the limestone quarry. The 
mill has 8 rotaries and an approximate capacity of 1,400 barrels. For the 
plan of the works the writer is indebted to the Henry S. Spackman En- 
gineering Co., Philadelphia, who constructed the plant.

first constructed. 
The Lehigh Portland Cement Co. works practically the same raw 
materials. The stone and clay pass through a Gates crusher together 
and then through a rotary dryer; from here the mixture passes through 
a Williams pulverizer into tube mills driven direct by electric motors. 
The rotary kilns are 60 by 6 feet. The clinker is ground, or was at the 
time of the visit, by a Williams mill and tube mills. Electrical trans- 
mission is used throughout and hence no belts are seen except in engine 
house. The available power. is 700 horsepower. . 
At Ironton a new plant has been erected, that of the Ironton Portland 
Cement Co., using the limestone found at this place, and clay. The ma- 
terials are ground in a Gates crusher, a Williams mill and tube mills, 
and the clinker passes through a Kent mill, replacing ball-mills, and finally 
through tube mills.
