3. CONGLOMERATE ORES. 



Conglomerate ores, although not so extensively developed areally through- 

 out Cass County, are yet of sufficient importance to be considered equal to 

 either of the laminated or nodular concretionary ores. 



This ore is a mixture of ferruginous pebbles of sizes ranging from half an 

 inch to an inch in diameter, ferruginous sands and gravels, and occasionally 

 a siliceous pebble cemented together by oxide of iron. In the purer con- 

 glomerates siliceous pebbles are usually absent, and these also contain a greater 

 proportion of the iron cementing material. 



These ores are generally found occupying positions along the banks of the 

 streams in the district, particularly in places where these streams have cut 

 through the first or lower range of ridges lying between the lowlands of the 

 country toward the east and north and the upper or main ridges. They are 

 frequently found capping or lying high up on the sides of the lower hills 

 occurring amongst the main chain of ridges. 



The most extensive deposits of this class of ore found in Cass County oc- 

 cur on the south side of the Albert Emanuel and west side of the David W. 

 Gilbert head rights. This deposit lies upon both sides of a small creek and 

 rises about fifty feet above its bed. The ore is in large quadrangular blocks 

 measuring from two to four feet along each side. The actual thickness of the 

 deposit is not known, as no excavations have ever been made. It is evidently 

 over five feet in thickness. Experimental tests made of this conglomerate 

 show it to produce a fine light gray soft iron, and to carry about thirty per 

 cent of metal. 



The next deposit of any extent is on the side of a hill on the southeast cor- 

 ner of the Samuel Harrison headright, close to Mr. M. Powell's house. Here 

 the blocks are scattered, and many of them tilted on edge. They are par- 

 tially covered by a gravel, which appears to be the result of a disintegration 

 of the conglomerate ores themselves. The hill appears from a section in the 

 stream at Mr. Powell's house to be composed of a mottled sandy clay. The 

 following is « section from the bank of the stream at this place:
