In the very western part of Jones county, I first met with the 

 limestone of the secondary formation. It is on the plantation 

 of Mr. Humphreys, at the heads of New river and Trent river. 

 The rock lies in a heavy ledge on the borders of a swamp ; its 

 surface is much worn and ragged. It is of a straw color, and 

 apparently of good quality for making lime ; — on submitting a 

 piece to chemical examination, I find it as good as the limestone 

 of this formation usually is. It yielded in one hundred parts,

Several springs come out at its edge, which bring up small fos- 

 sil shells and pieces of coral. Among the shells, which are gene- 

 rally very imperfect, may be recognized the Pecten membranosus, 

 a Cardium, and others common to the same formation in New- 

 Jersey. The water seems well adapted to the recent Planorbis 

 trivolvis, Physa heterostropha, and Paludina Integra^ which in- 

 habit it in profusion, and also to the luxuriant water-cresses, 

 which equally abound in it. Ai'ound the limestone is a deposit 

 of calcareous marl of a light yeUow color, aftbrding a very con- 

 venient and rich natural manure ; but it has been entirely neg- 

 lected as well as the limestone, the little lime required for the 

 country being brought from Thomaston, Maine, although they 

 have enough of the rock, wood at the expense of cutting it 

 only, and a suitable sandstone for kilns, scattered through this 

 region. This stone belongs to the same formation, and has been 

 used sometimes for making millstones. Having fortunately some 

 plans of kilns with me, I was happy to leave them, with the 

 advice that the people make the attempt at least to supply them- 

 selves with their own lime.
