GENERAL GEOLOGY. 



Fig. 7. 



No. 3. Soft, irregularly bedded, Magnesian limestone, passing up 



into purer and more regularly bedded limestone .• 40 feet. 



No. 2. Ligbt gray oolitic limestone, in heavy layers 15 feet. 



No. 1. Yellowish, shaly, fine-grained sandstone 20 feet. 



No. 1 of this section at Indiantown is equivalent to No. 1 of the section at 

 Burlington ; No. 2 is equivalent to No. 6 there ; and No. 3 to No. 7 at the same 

 place. The characteristic fossils of the Kinderhook formation prevail throughout 

 the whole series of beds found at Indiantown, even including the whole forty 

 feet of No. 3. Although the upper part of No. 3 presents the lithological 

 appearance of some parts of the Burlington limestone, yet its distinctive 

 palseontological characters are wanting or feebly shown. The whole is there- 

 fore referred to the epoch of the Kinderhook beds, especially since the line of 

 demarkation between the rocks of that epoch and those of the Burlington lime-

At Orford, near Indiantown, bed No. 2 is well exposed, and 

 is there extensively quarried for lime, as it is also at the last
