GEOLOGICAL RECONNOISSANCE 



also, a set from Mr. M. L. Robinson's land, two miles north of Jackson- 

 port. At the latter place, No. 2, the cultivated soil, was selected from an 

 old field fifty years or more in cultivation, and has produced for the last 

 twenty years successive crops of cotton, with an average yield of about 

 eight hundred pounds of seed cotton per acre, rating in the New Orleans 

 market in quality equal to the Mississippi cotton, and having a rather 

 better staple than the cotton from Tennessee. 



The principal growth of timber on this land is black, white and post- 

 oak, sweetgum, blackwalnut, and some hickory. 



The Cairo and Fulton railroad crosses White river near Jacksonport, 

 and runs along Village creek, through the northern part of the county. I 

 was informed that as many as one hundred and fifty hands were employed 

 this season in its construction in Jackson county, and it is hoped that the 

 completion of so important a work to the State, is placed beyond a doubt. 

 The large grant of lands bordering on the road, it is estimated will be 

 sufficient to pay for its construction.

INDEPENDENCE COUNTY. 



The geological formations in the part of this county explored by me, 

 are exhibited in the following section: 



On the road from Jack- 

 sonport to Batesville, 

 after reaching the high- 

 land some five miles in 

 a westerly course from 

 Black river, the water- 

 worn quaternary horn- 

 stone and chert gravel 

 (k) of this section is 

 found capping the tops 

 of the hills as far west 

 as range 4. This gravel 

 bed sometimes rests upon 

 the ferruginous sand- 

 ston (/), and sometimes 

 immediately upon the 

 buff-colored sandstone 

 (/); but was nowhere 

 recognized in connection 



Conglomerate ami millstone grit, with interca 

 lated shale and schistose sandstone, 4d0 feet 

 in thickness.
