an almost horizontal position. At some localities a general study of the 

 rock indicates that more or less horizontal beds were repeatedly attacked 

 on the west side by waves. The westward-sloping cut-out margins of these 

 beds were later covered by similar sand beds, which were themselves nearly 

 horizontal. This whole series at present dips in a general way southward 

 at an angle of about 20^. Toward the south the strike seems to be more 

 nearly N. 60^ E., dip 45*^ E., the dip decreasing rapidly southward until it 

 becomes only about 10^. It is difficult to determine the real strike of the 

 more southern shore outcrops. 



North of the fault line mentioned above, the sandstone rarely contains 

 pebbles over an inch long. Southward for some distance there are distinct 

 conglomerate layers. The pebbles usually do net exceed 3 inches in 

 length, although some beds show pebbles somewhat longer, considerably 

 stretched. Grranite pebbles are not infrequent, but are hardly recognizable 

 on account of the extreme shearing. 



A very coarse conglomerate, some of the pebbles a foot in length, 

 occurs along the farm road west of the house on the west side of Windmill 

 Hill. Many of these pebbles are composed of quartzite and are of much 

 larger size than the pebbles in the exposures along the bank farther south. 

 They occur between the 60-foot and 80-foot levels. 



Nothing is known of the stratigraphic position of these rocks. The 

 following remarks, however, may be pertinent. The present eastern mar- 

 gin of the Carboniferous basin, as a rule, shows arkose and coaly shales as 

 the basal beds. Overlying these is sandstone, often with conglomei^ate 

 layers. If the mass of coaly shale, sandstone, and mostly fine conglom- 

 erate so far described be conceded to represent the basal beds of the 

 Carboniferous series in this region, then the veiy coarse conglomerate so 

 abundantly exposed in the bed of the farm road on the west side of Wind- 

 mill Hill may be considered as representing a higher horizon and as ovei"- 

 lying at least the great mass of the sandstones. 



If this view be correct, the coarse conglomerate on the west side of 

 Windmill Hill could then be correlated with the coarse conglomei^ates 

 exposed at High Hill Point, Fogiand Point, the northwest side of Nonquit 

 Pond, and thence northward.
