The attention given to the petroleum inter- 

 ests has somewhat retarded the recent develop- 

 ment of coal, which ranks second in importance 

 among the minerals of the state. The coal 

 fields extend from Kansas to Arkansas, and 

 have an area of about 20,000 square miles. 

 Most of the coal is now obtained in Pittsburg, 

 Coal, Okmulgee and Latimer counties. In the 

 production of natural gas, Oklahoma is one of 

 the leading states, and the production since 

 1910, when the state ranked fifth, has greatly 

 increased. Lead and zinc are mined in Ottawa 

 County, in the northeast, which is a part of the 

 lead and zinc region of southwestern Missouri. 

 Clay products, principally common brick, lime- 

 stone, asphalt, gypsum, lime, cement rock, py- 

 rite, salt, sand, gravel and commercial mineral 

 waters are other minerals of importance, and 

 granite, copper, iron, gold and silver are found 

 in small quantities. 



Manufactures. The great development of the 

 oil and coal as fuel resources and the abundance 

 of agricultural and mineral products have caused 

 an increase in manufacturing industries. First 



in importance is the production of flourmill 

 and gristmill products; this is followed by the 

 refining of oil, the manufacture of cottonseed 

 oil and cake, lumber and timber products, and 

 printing and publishing. Oklahoma City, Enid, 

 Muskogee and Guthrie are the centers of the 

 flour milling and printing and publishing indus- 

 tries. Steam railroad car repairs and foundry 

 and machine-shop work are also important. 

 Oklahoma, in the first decade of its history as 

 a state, reached thirty-eighth place among the 

 manufacturing states of the Union. 



Transportation. The state is well supplied 

 with railroad transportation facilities, for it is 

 traversed by trunk lines from east to west, 

 north to south and northeast to southwest. In 

 1914 there were 6,357 miles of railroad in the 

 state, not including the short spurs. All im- 

 portant towns are on one or more lines, and 

 there are wagon roads between railroad stations 

 and small settlements. Oklahoma City, Tulsa, 

 Muskogee, McAlester, Guthrie, Chickasha and 

 Enid are the railroad centers. The principal 

 lines in the state are the Chicago, Rock Island 

 & Pacific; the Saint Louis & San Francisco; 

 the Atchison, Topeka & Santa Fe; the Missouri,
