NOVA SCOTIAN GEOLOGY—HONEYMAN, 255 
on the Beech Hill road. This shews that the high ground on 
the right is formed by these pre-carboniferous rocks. Above the 
bridge the continuation of these rocks is manifest by the expo- 
sure in the bed and sides of the brook, and in outcrops on the 
high lands on the right. Below the bridge are several branches 
of the brook, the most important has two falls, the lower and 
upper, the one at Mr. Webster’s farm, the other near the summit 
of the height of New Canaan. 
The rocks of the area are slates and shales with occasional 
arenaceous beds. Their colouring is sufficiently varied, some- 
times it is beautiful and ornamental. The colours are red, yel- 
low, fawn coloured, black and grey. They are not so highly 
metamorphic as the rocks of the preceding area, and their stratifi-. 
cation is more obvious. There are also fossils in one member of" 
the series. In the brook at Kentville some of the strata are yel- 
low with beautiful red, wavy lines, having the appearance of” 
woody structure (pine). At the dam the slates are black and. 
deep red (ochrey) with oceasional green, being coloured by films 
of carbonate of copper. At Webster Falls there is a set of fawn. 
coloured slates of considerable thickness, having sandy strata 
with a vesicular structure. I was fortunate enough to come upon 
a part of the fawn slates having Dictyonema Websteri (Hall), 
named after the discoverer, the late Dr. Webster. The strata of 
the Upper Falls are black slates, almost like roofing slate. The 
height and arrangement of the strata must form a beautiful 
waterfall when the brook is well filled with water. 
The Dictyonema and other strata of the area have been refer-. 
red to the Niagara Limestones (Upper Silurian Period), on the- 
slender paleontological grounds of Dictyonema occurrence.. 
Others are disposed to regard this as an evidence of Lower: 
Silurian age, so that the age of the rocks of this area may also: 
be regarded as doubtful. Ihave not observed any unquestion- 
able Upper Silurian rocks of similar aspect. In Cape Breton» 
Dictyonema is a Lower Silurian form, the same is the case at 
Quebee. It occurs in the Upper Lingula Flags of Wales. The 
revelations of Nictaux and the occurrence of Asaphus ditmarsiae 
at Clement’s tend to shake faith in received opinions, The:
