NOTES ON RECENT SEDIMENTARY FORMATIONS — ELLS. 417 



the trappean rocks bein^' apparently very similar to those found 

 in the Annapolis Valley, and being also favourable to the 

 growth of fruit trees. 



The extension of the trap ridge of Kings County to the 

 eastward is seen in a scattered group of islets known as Five 

 Islands, and Partridge Island, near Parrsboro, while to the west 

 the bold bluffs of Capes Sharp and d'Or, and further down the 

 Bay the cliffs of Isle Haut represent further outbursts of similar 

 igneous rocks along the northern margin of this area of disturb- 

 ance and volcanic activity. 



The relations of the volcanic rocks, generally known as Trap, 

 to the associated sandstone are well seen at several points, and 

 from the study of these it would appear that the former is the 

 more recent. The intrusion of the volcanic into the sedimentary 

 is clearly seen, and the sandy layers along the contact are not 

 only pushed upward on either side of the dykes, but the red 

 rock is metamorphosed to a certain extent, as seen in the discol- 

 oration of the beds and by their alteration to a more quartzose 

 condition. In fact the whole range of the North Mountain is 

 practically only an immense sheet or overflow of igneous rock 

 which has issued through a line of fissure, traversing both the 

 red Ti'iassic beds and the underlying Carboniferous strata, and 

 spreading out northward in the direction of the waters of the 

 Bay of Fundy. This trap ridge consists of a series of layers of 

 various kinds, in which are found heavy columnar rocks, forming 

 pillars as regularly shaped as those of the Giant's Causew^ay. 

 These can be well seen at various places along the north side of 

 the promontory between Capes Blomidon and Split. Other 

 layers are ashy and soft, others again reddish and felspathic or 

 amygdaloidal, and certain beds contain masses of beautiful 

 zeolites, amethysts and agates, which have caused .this belt of 

 rocks to be celebrated far and wide among mineral collectors. 



At several places along the Bay of Fundy shore of the North 

 Mountain, the trap, which for the most part forms an unbroken 

 wall for sevent}^ miles, is overlaid by newer sedimentary beds. 

 Probably the most conspicuous deposits of these are situated a 

 short distance west of Scot's Bay. One of these is well seen in
