BETWEEN SACKVILLE AND AMHERST. 



85 



scooped out, so as to form the hollow 

 in which the Tantamare Marsh now 

 exists. 



No. 3 is grey-sandstone conglo 

 merate which very frequently overlies 

 these gypsiferous marls, being the base 

 of the productive coal-measures. The 

 hardness of this rock has enabled it 

 to withstand the action of the water, 

 and to form the ridge on which Fort 

 Cumberland stands. 



No. 4 represents the productive coal- 

 measures, greenish -grey, generally 

 thin-bedded, and more or less soft 

 sandstones, with shales and thin beds 

 of coal which have been more easily 

 washed away by the currents of water. 



No. 5. I am uncertain from my 

 notes whether this is the grey sand 

 stone and conglomerate which often 

 underlie the upper coal-measures, or 

 whether it is a repetition of the red 

 sandstone of Sackville. If it be the 

 latter, then 



No. 6 is a repetition of the gypsi 

 ferous red marls of No. 2, and there 

 exists a dislocation by which the Fort 

 Lawrence Eidge has been thrown up. 

 If No. 5 be a grey-sandstone conglo 

 merate, as I am inclined to believe, 

 then No. 6 represents the upper coal- 

 measures thin-bedded, soft, yellow 

 sandstones, easily scooped out by the 

 ancientc urreuts. 



No. 7 is the red sandstone, marls, 

 and gypsum of Nos. 1 and 2, certainly 



Amherst.
