HARRISON COUNTY.

The elevation of this cutting is 460 feet above tide. 



The stratified red and white sand and sandy clay (No. 6) of this section 

 is seen in various cuttings between this place and the centre of the town of 

 Marshall, and also stretching north and east of the town. 



At the pumping house of the Marshall City Water Works a section of the 

 hill gives the following: 



1. Brown gravelly sand 5 feet. 



2. Laminated ore and ferruginous sandstone 1 foot 6 inches. 



3. Stratified red and white sand and sandy clays, with mottled sand in 



front 45 feet. 



Add to this, section of wells bored in valley of Walnut Creek : 



4. Surface soil, brown sand and gravel, 12 to 15 feet (wash from hills on 



either side). 



5. Blue clay 3 feet. 



6. White sand with some gravel, with increase of gravel towards bottom, 43 feet, + 



Total 97 feet 6 inches. 



The elevation of the top of this cutting is about 387 feet above sea level. 



Along the Marshall and Longview road going west from Marshall the cut- 

 tings made for drainage and other purposes, as well as the washouts, show a 

 series of almost horizontal beds of brown unstratified sand, ferruginous mat 

 ter, and stratified red and white sands and sandy clays, with occasional 

 patches of mottled clay and sand for nearly four miles. At the hill on the 

 S. P. Hall head right the level of the country suddenly falls about fifty feet. 

 The cutting shows the following section: 



1. Brown unstratified sand, with fragments of laminated ore 3 feet. 



2. Stratified white and red sand and sandy clay 40 feet. 



3. White sand at base having a stratified appearance with an easterly dip of 20° . . 6 feet. 



The brown sand (No. 1) overlaps the end of the white and red sand and 

 clay and also covers the white sands. Half a mile farther west these white 

 sands (No. 3) form the surface for a few yards, when they again disappear 

 under yellow sands. In the western exposure the white sands have a slightly 

 western dip. These sands are also seen on the Jose Sanchez headright. In 

 this place, however, they are more of a clay than a sand.
