colour, uiid the other volcanic, cinlirficino' a variety of doleritic, 

 trachytic, and ainy^'daloidal rocks disposed in successive sheets 

 as the evident result of rejx'atiMl lava Hows It has l»een usual 

 to rejj^ard both of these i^roups as hcint,' of New K(m1 sandstone or 

 Jura Ti'ias a<,'e. But at present there is, in this reoion, abso- 

 lutely no ])njof that such is their true ])osition, while observa- 

 tions made elsewhere, in I'oeks of siniilai- character and associa- 

 tions, at least make the reference somewhat doubtful. 



P)y far tht; best opjtortunity for the study of the sandstones 

 is atfbrdiMJ by the shore section closely adjacent to the so-called 

 "sea wall," about six miles from Di^by, in the settlement of* 

 Rosswfiy. At this |)oint is expostid a series of bluffs which, both 

 by their hei^^ht and coloui', form a striking' feature in the land- 

 scape. Tin; section is nearly half a mile in length, gradually 

 rising' with the <li|) of the strata from tin.' watei- le\-el at the 

 northei'n end to (piite one hundred feet at thi.^ southei'n This 

 heiuht above the sea level is not \ei'v ditl'ei'ent fi'om that seen 

 on. the road from the town of Di^diy to ])i<^d)y Li^ht, and would 

 indicate that the depression in winch these sandstones were 

 deposited, and which must at one time have connected the waters 

 of Anna])olis l]asin and St. Mary's Bay, must have had at least 

 a corresponding; depth below its present level. 



In chai'acter the sandstones are not unlike those seen at 

 various points in the Annapolis valley, but they lack, as far as 

 observed, the oypsiferous as))ect which is so marked a feature 

 in the sandstones which underlie the traps of .>lomid(jn. The 

 prevailing colour is a brick-red, of lio-ht and dark shades. At 

 intervals it is intei-stratitied with light green bands varying in 

 width from half an inch to 5 or G inches. The green bands 

 especially characterize the lower beds, and these are also dis- 

 tinctly n)oi"e arenaceous than the beds above, (ju one of 

 the reefs laid bare by the tide was observed what appeared 

 to be a tree-trunk several feet in length, together with some 

 obscure branching mai'king.s, which resend)led tracks, but 

 both were obscure, and nothing else of this natui'e could be 

 found.
