A highly important section is ilhistrated in Fig. 41. It extends 

 from Mount Battie southerly beyond Rockport, a distance of four 

 miles, but it crosses every member of the Taconic series in Camden. 

 At the bottom we find the older mica schist, in Rockport. Above 

 it in nearly regular succession are the successive members of the 

 Taconic system. They are in the ascending ©rder, Hyaline quartz, 

 dark colored quartz rock, dark colored silicious slate, quartz rock 

 and conglomerate, limestone conglomerate, thick-bedded limestone, 

 (the last two members are Eolian,) micaceous quartz rock, wrinkled 

 clay slate, argillo-micaceous schist. The four first members are 

 properly parts of the formation quartz rock, and the last three are 

 parts of the Taconic schists. Estimating the thickness trigonomet- 

 rically, we should say the quartz rock is at least 1,084 feet thick, 

 the Eolian limestone 630 feet, and the schists 1,690 feet thick. 

 The conglomerate upon Mount Battie is supposed lo be the equiva- 

 lent of the quartz, and is 500 feet thick, which is very nearly that of 

 the lowest member of the formation in Rockport. Hence the total 

 thickness of the series in Camden is at least 3,404 feet. We have 

 taken care not to over-estimate. 



This spction illustrates the fact that none of these rocks are 

 repeated by axes, save some unimportant flexures in the upper
