 A pretty deep section of the beds belonging to this portion of 



the marl region, is beheld in Richard's Hill, about two miles 

 north of Mullica Hill. A loose yellowish sand containing a few 

 of the green grains, and having the depth of about five feet, 

 occurs on top, being underlaid by about seven feet thickness of 

 ferruginous sand full of disintegrating shells, casts, and concre- 

 tions, intermingled with a small amount of the greensand or marl 

 grains. Below ihis there occurs a brown ferruginous sand, con- 

 taining a few of the granules, indistinct casts, and cemented 

 lumps or concretions of the same with the calcareous matter of 

 the shells. Beneath all, and nearly at the base of the hill, is a 

 bed of unmixed ochreous ferruginous sand, very yellow. It has 

 been dug by the meadow side, and applied to the soil, but with 

 what good results I know not. By adverting to the section at 

 Mullica Hill, to be given next, it will be seen, that this last bed is 

 in all probability the same which lies at the base of the series 

 there, and that to search, therefore, lower in the earth at this 

 place for a purer marl than that half way up the hill, would be to 

 experiment without hope of success, or at least any that could 

 be justified by our present knowledge of the marl stratum in this 

 quarter. 



About four miles northeast of Mullica Hill, a marl is dug in a 

 ravine near the road which leads to Woodbury, which is of a 

 dark green colour, and found to be extremely beneficial upon the 

 land. 



Analysis shows it to possess the following

 formed by the valley of Raccoon creek, exposes an interesting 

 series of beds through a height of about forty feet. The upper-
