HARRISON COUNTY. 129 



same positions, the two grades of conglomerate ore are found scattered in the 

 form of large irregularly shaped blocks. The lower and more recent of these 

 deposits are frequently in a thinly bedded condition. 



The geode or nodular concretionary ore, although sometimes found among 

 the higher yellow and gray sands, belongs more essentially in this county to 

 the dark brown and red sands belonging to the middle division of the county. 



In thickness these deposits vary from the scattered deposits of a few inches 

 to a maximum thickness of twelve or fourteen feet for laminated ore. For 

 nodular, concretionary, and conglomerate ores no thickness can very well be 

 given, as those ores are generally found in the form of nodules or bowlders. 

 Probably the heaviest deposits of nodular ore are those found on the W. C. 

 Crawford head right, where, mixed with a brown sand, it reaches a thickness 

 of four feet. On the J. M. Dorr headright the same material is about seven 

 feet. The conglomerate ores are generally found in the form of large irregu- 

 lar blocks or bowlders, and measure in places from 2x2x1 to 6x^x2 

 feet, and many are even larger — some on the north side of Little Cypress 

 Creek having a size of over ten feet in length and from three to five feet in 

 thickness. On the C. Grillet headright it forms a ridge of blocks for some 

 distance and having an elevation of about fifteen feet. 



In that portion of the county lying to the north of the Little Cypress Creek 

 the ores found consist of laminated and conglomerate ores, the conglomerate 

 greatly preponderating. At Oney's Mill, on Eagle Creek, on the S. B. Simp- 

 son headright in the western part of the county, the conglomerate ore lies upon 

 both sides of the creek in the form of huge masses, some of which measure 

 ten feet in length, eight feet in width, and over three feet in thickness. 

 These huge blocks lie piled on the top of each other to a height of over 

 twenty feet along both sides of the creek for more than two hundred yards. 

 Further down the stream, and underneath these blocks, a bed of laminated 

 ore of the massive variety about a foot thick appears in the breaks of the hill 

 along the widening bottom connected with this stream. This is on the 

 eastern bank of the creek, and along the western bank these ores appear in a 

 similar relation to each other. Oney's mill is situated within a few yards of 

 the crest of the divide between the two Cypresses and on the south side. On 

 the north side of this divide a small stream, tributary to the Big Cypress 

 Creek, flows through a region covered by similar blocks of ore. These ores 

 are on the S. B. Simpson headright, and they also occur on the John Morton, 

 Dan Jones, M. Redding, and other headrights in this neighborhood, at which 

 places they have about the same thickness. On the H. Oney and J. Oney, 

 two small headrights southeast of the S. B. Simpson headright, laminated ore 

 in a very broken condition shows a probable thickness of three or four feet.
