and has a yellow crust. These pits lie in the side of a hill, on 

 the road from the mills to Johnson's house. Around this neigh- 

 bourhood the land is rather high, and hence perhaps the true 

 marl has not yet been reached. The proximity of this impure 

 marl to the railroad, makes it desirable, if possible, to learn 

 whether the true greensand bed does not lie below it at an ac- 

 cessible depth. 



Three miles from Englishtown, on the Matchaponix creek, at 

 John Perrine's saw-mill, the same stratum is seen as at Rue's. 

 It is not so destitute of the grains of marl as to be entirely unfit 

 for use. It occupies the bed of the creek for some distance 

 below the saw-mill. It is sandy and micaceous, with small 

 irregular concretions of clay cemented by oxide of iron, and a 

 few grains of marl. 



In many parts of this section there is a stratum of a mottled 

 bluish clay with blotches of yellow ferruginous clay. This lies 

 over the spurious marl stratum, and looks not unlike the upper 

 marl bed at Middletown and its vicinity. 



Around the parsonage, two and a half miles from Englishtown, 

 on the road to Freehold, the marl is pretty good, though a little 

 impure from containing some sand and clay. At no great depth 

 it contains shells and other fossils. The soil is sandy, but grows 

 better to the northwest. All the indications of the marl region 

 are present here. 



In and around the farm of Mr. Hunt, one mile from Blooms- 

 burg tavern, the marl lies extensively denuded in the meadows. 

 It is pretty good, consisting mainly of greenish grains, with a 

 good deal of clay. These meadows are very ferruginous, and 

 contain bog iron ore.

The proportion of potash which this marl contains, deduced 

 from that in the greensand, is 8-6 per cent.
