COAL.

possible that the quality will improve when developed deeper. The iron 

 pyrites appear in the seams in the coal, and may be the result of a combina- 

 tion of the sulphur so abundant in the alum bearing clays with iron deposited 

 from percolating water. 



Of the Waldrip coal I am not so certain. Owing to the condition of the 

 mine, I was unable to go into it. Some of the people interested in its devel- 

 opment have told me that there is very little sulphur, but I fear they under- 

 estimate the matter. At Brady, where I saw some of the coal, iron pyrites 

 showed plainly in most of the pieces. The quantity of sulphur in the coal at 

 these two points is too great to admit of its use in the best iron work, and I 

 fear that most of the coal will have the same fault. I will say, however, that 

 in coking fully one-half of the sulphur is driven off; and furthermore, that 

 the Arkansas and Indian Territory coals are used in iron work, although they 

 carry a considerable quantity of sulphur. I give below a table of analyses of 

 coals from different parts of the Waldrip beds:

Ikon. — In some of the beds both above and below the Waldrip series there 

 is a great quantity of iron ore in the form of nodular hematitic ironstone in 

 the clay. This iron appears to be very rich. The analysis is as follows: 



Silica 4.37 



Ferric oxide 89.73 



Alumina 5.47 



Sulphur 0.10

Phosphosus Trace.

Metallic iron 62.81 



Analysis by L. Magnenat. 



In places this iron may be in sufficient quantities to pay for working in 

 connection with the coal, provided the coal is found to be suitable for iron 

 making. On Bull Creek this iron is very abundant; and near Home Creek, 

 about five miles west of Trickham, there is a bed containing such quantities 

 of this ore that the surface over several acres is strewn with the nodules. 

 There are many tons on a few acres of the surface at this point.
