GEOLOGICAL EEPORT. 31 



" Iron ore is found at many localities in Pulaski county. A 

 large deposit of specular iron ore, similar to that used at the 

 Meramec Iron Works in Phelps county, was examined by Mr. 

 Engelmann in Sec. 31, T. 37, R. 12. In N.E. qr. of Sec. 30, 

 T. 36, R. 11, there exists a large deposit of brown hematite. 

 It occurs in the cherty beds of the 2d Sandstone and 3d Mag- 

 nesian Limestones. Large masses of brown hematite were also 

 observed on the hills of Bee Branch, in T. 37, R. 10. In a 

 cave in Sec. 19, T. 36, R. 8, sulphuret of iron occurs. Sul- 

 phuret and brown hematite are also found in Sec. 9, T. 38, 

 R. 13. 



" Fragments of brown and specular ore were observed at many 

 points in La Clede county, but only in small quantities. Mr. 

 Engelmann observed large masses of brown hematite near Bear 

 creek, in Sec. 25, T. 36, R. 14. 



" Jefferson County. In N.E. qr. of Sec. 4, T. 39, R. 4 E., on 

 land belonging to Mr. Prcntiss, is a deposit of brown hematite 

 which appears to be of good quality. The ore projects in large 

 masses above the surface of the ground, and the indications are 

 that it exists in workable quantity." 



ABSTRACT FROM MR. 



" Near the line between Webster and Green counties, in 

 Sec. 18, found hematite in fragments, some of them quite 

 large. They occurred in a ravine about the line between the 

 Saccharoidal Sandstone and 2d Magnesian Limestone. 



"In Green county, in Sees. 24 and 25, T. 29, R. 24 W., 

 on the summit and sides of a low hill, masses of brown hema- 

 tite of a good quality were found. The underlying rock, as 

 observed at the nearest locality, was Encrinital limestone. 



" Iron ore is abundant in Maries county, occurring both as 

 a hematite and a sulphuret. The sulphuret is found in small 

 quantities in many places. It is most abundant in Sees. 28 

 and 30, T. 38, R. 9 W., on railroad land. The sulphuret is 

 frequently changed to an oxide on the exposed surface. 



" Good specular ore was found abounding in large masses in 

 Sec. 5, T. 39, R. 11 W., associated with argillaceous hematite. 

 This locality is worth exploring.
