The measurements are based on pacing, but are sufficiently 

 accurate to exhibit the stratigraphic characters of the section, 

 the dip and strike of which agree closely with that of the 

 first outcrop. Flattened plant stems occur in the shales of 

 bed No. 6 and again in No. 9. The plants are calamites and 

 the stems of ferns, but no fronds of the latter have been 

 found. 



Carboniferous, red series. — For about 3800 feet north of 

 the above described section, there are no outcrops along the 

 line of the railroad. At this distance from the gray rocks, is a 

 cut in reddish strata having the typical lithological characters 

 of most of the rocks in the Norfolk County basin and the 

 lower portion of the Carboniferous in Attleborough, Mass. 

 The strata dip steeply to the south or are in places nearly ver- 

 tical. The section from south to north apparently in descend- 

 ing order is as follows : 



1. Fine quartzite conglomerate, with quartz veins 25 feet. 



2. Red sandstone and slate 15 



3. Fine quartzite conglomerate, with quartz veins 20 



4. Ked and gray sandstone . 30 



5. Red sandstone . . . 50 



6. Fine quartzite conglomerate and sandstone 10 



7. Red slate 6 



8. Limestone, a lens, highly cleaved (I -5 ) 



9. Red sandstone and slate 10 



10. Red slate 15 



11. Dike, diabase? (1-5) 



12. Calcareous white and red slates.. 2 



13. Red slates 10 



14. Calcareous slates 4 



1 5. Red slates 30 



16. Red sandstone, with veins of quartz and calcite 5 



17. Red slates 20 



18. Covered beds . ..100 



19. Red slates 50 



These measurements, like those in the preceding sections are 

 based on pacing, the succession being made out on the west
