fined pebbles, mostly a quartzyte, the rock being really a 
quartzyte" ('98, pp. 67-68). 
A mile south of the village of Pubnico Harbor, where the 
railroad to Harrington crosses the same road mentioned in con- 
nection with cross-bedding, is a sericite schist, altered from a 
sandstone, and containing olive-green quartzyte pebbles, some- 
what resembHng massive serpentine. .This is probably part of 
the formation noted by Bailey in the same region. The schist 
has much fine biotite irregularly distributed through it. The 
pebbles are sufficiently resistant to stand ovtt well on the 
weathered surfaces, and occasionally these surfaces show pits 
due to loss of the pebbles. 
At Western Head, south of Lockport. Shelburne county, 
the sediments "include some . . . beds made up of well round- 
ed quartz pebbles of the size of bullets" (loc. cit., p. 56) . In 
describing the strongly conglomeratic rocks of Yarmouth, he 
mentions (p. 69) pebbles up to a foot in diameter, of gray 
quartzyte in some strata ; in others of a "gray or purple-gray 
vesicular rock," which he has not determined. In a ^IS. letter 
he speaks of them as ''feldspathic, and recalling the vesicular 
ash rock (trachytes?) of Huronian age underlying the Cam- 
brian rocks about St. John." He considers them practically 
basal, part of division la of his classification ; but on the map 
accompanying the report the whole region is colored as division 
II, the "banded argillyte division." 
At Westfield, Queens county, "near the mouth of a brook 
emptying into the Westfield river," is said by Bailey to be 
"a deposit of verv hard breccia or conglomerate, the cement of 
which is oxide of iron" (loc. cit.. p. 38) . A traverse of the 
river in the region indicated, failed to discover the strata, nor 
does the stream appear to contain pebbles of it. The nearest 
resemblance to a conglomerate was seen in a small piece of 
recently cemented breccia of whin pebbles, the matrix being 
iron rust. At the so-called Jumbo mine, a few hundred yards 
northwest of the bridge over the river, mentioned by Bailey in 
this connection, but not as containing conglomerate, is a vein 
breccia ; and where the margins of the leads have been faulted 
are many small slickensided lenses, sometimes cemented into a 
fault breccia. The hand specimens suggest a conglomerate, 
at first sisfht.
