Section 8th. — Arisaig Pier to the Mountains. 



The Arisaig Pier rocks begin the section. The first rock is 

 the Trap of preceding sections. It is here largely exposed in bold 

 reefs. The second rock is hard porcellaneous jasper, beautifully 

 banded with numerous veins of quartz and bari/te. These have a 



width of feet. Following these are sand and sand banks 



hiving arenaceous shales, apparently unaltered representatives of 

 the original of the porcellaneous jasper. They are of A and are 

 non-fossil iferous. After these come B shales, the fossil iferous 

 slates of A in sections 5th and 6th being missing. The B shales 

 are fossiliferous and have the apparently characteristic cone in cone 

 concretions. We have then a hill having B' strata. Descending 

 the hill we cross the road and following an old road ascend what 

 is locally called double hill. As we take the new road we come 

 upon Arisaig brook, and find on either side sections of double hill, 

 having abundance of fossils of B'. On the top of the highest 

 (second) part of the hill the outcropping strata produced a lingula 

 of unusual size. The succeeding strata exposed on the side of the 

 brook, show a ferruginous bed, about nine inches thick ; some parts 

 of this bed have the qualities of iron ore. It is very fossil iferous. 



The fossils seem to indicate the horizon of C Aymestry lime- 

 stone. Regarding this section as dividing the area of the upper 

 series into two parts. This bed may be considered as a passage 

 between C of the tivo divisions. These strata dip at a high angle. 



Proceeding along the old road we have other strata exhibiting 

 both a northerly and a southerly dip. This is the approximate, 

 position of the synclinal axis. The southern strata are non-fossil-, 

 iferous — they are red and gray. From their relative position to the 

 strata succeeding in the line of section, and from considerations to 

 which I shall afterwards turn attention, I am disposed to regard 

 these as part of a higher member of the upper series, i. e., higher 

 than D Upper Ludlow, and consequently equivalent to the Ludlow 

 tilestone of England. I would designate this E of Upper Arisaig 



series. Succeeding this at a distance of feet strata are seen 



outcropping in considerable extent. These have abundance of 

 fossils of D Upper Arisaig. Descending the hill no farther outcrops,
