262 TRANS. ST. LOUIS ACAD. SCIENCE. 



The divisions as given above will be used in the present essay. 

 T.wo districts, however, which do not contain any ores themselves, 

 but which have nevertheless become very important manufactur- 

 ing centres, will have to be added, namely, 



V. The manufacturing districts of St. Louis and Grand Tower. 

 The former of these two districts is partially, the latter wholly, 

 situated in the State of Illinois, but both use Missouri iron ores 

 almost exclusively. 



It is intended to give in the present essay a brief review of the 

 five industrial regions above mentioned, in regard to their loca- 

 tion and extent, to their means of inter-communication, to then- 

 resources for the iron manufacture, and, finally, in regard to the 

 actual development of these resources, according to our present 

 stage of information. 



I. EASTERN ORE REGION. 



Extent.— The Eastern iron Ore Region of Missouri extends 

 over the following counties, in which iron ores are known to 

 exist, namely: Butler, Stoddard, Bollinger, Cape Girardeau, 

 Wayne, Reynolds, Iron, Madison, Perry, Ste. Genevieve, St. 

 Francois, Washington, Jefferson, and Franklin. 



Means of Communication. — The Franklin County district has 

 its commercial outlet over the Atlantic and Pacific railroad, 

 through the stations Moselle, St. Clair, and Stanton. The iron 

 ores of Ste. Genevieve, Perry and Cape Girardeau Counties will 

 have to be shipped from various points on the Mississippi. 



All the other districts in the Eastern region are situated along 

 the St. Louis and Iron Mountain Railroad. This road, after leav- 

 ing St. Louis County, and passing near a few iron ore deposits in 

 Jefferson and Washington Counties, divides into two branches at 

 the station of Bismarck. A few miles further south the western 

 branch reaches the Iron Mountain district with its specular ores, 

 in Southern St. Francois and Northern Iron Counties, and after- 

 wards runs through the western half of the south-eastern limonite 

 district, through Southern Iron County, through Wayne and But- 

 ler Counties, and thence farther south into the State of Arkansas. 

 At Poplar Bluffs, in Butler County, it joins the Cairo, Arkansas 

 and Texas Railroad, which runs eastward to the Mississippi 

 River, and thus forms another outlet for the mining districts of
