388 THE PICTOU COAL FIELD — POOLE. 



Cflomerate beds that are rusty and carry pebbles of white quartz 

 arc easily traced from A. McLean's house across four ravines 

 westward for 30 chains and are then supposed to be lost against 

 a fault coming from a shoulder of the hills and extending to J. 

 Reevy's in the valley, parallel to the fault at Patrick's oil coal 

 pit. At least it may be assumed that the influence of the pair 

 of Fulling Mill faults reaches this line and the regularity of the 

 syncline onward to McLellan's brook is seriously disturbed. At 

 Reevy's, where the McGregor slope and fault of Logan's Report 

 are to be found, the opposite dip is met with and both the George 

 McKay and Captain seams are supposed to be recognized, but 

 their outcrops have not been traced eastw^ard to connect there 

 with better know^n ground. 



Minerals. 



Within the circumscribed limits here dealt with the only 

 mineral of present economic importance other than coal is tire- 

 clay, but short reference may be made to others of interest on 

 account of their association. 



Goal. — Analyses of many of the coals are given in the Survey 

 i-eport for 1869, page 365 ; in How's Mineralogy of Nova Scotia^ 

 1869 ; in the Coal Fields of Nova Scotia by John Rutherford, 

 1871 ; in Dr. Gilpin's papers in these Transactions and in Prof. 

 Johnson's oft quoted report of 1843 and referred to, page 411 of 

 the Survey report of 1869. The variation in the composition of 

 the several seams in different parts of the field has already been 

 mentioned and the analyses published in Acadian Geology illus- 

 trate the variations met wnth in the several layers that go to 

 make up some of the large seams. The only note of interest that 

 may be added is that while the coals of the lower series, chiefly 

 found to the west of the East river will all coke, those of the 

 upper series to the east are much drier and are non-coking coals. 

 All the coals of this field are non-caking. 



Fireclay. — Beds of fireclay are numerous. Few have been 

 analysed and their value determined. Most of them contain 

 nodules of clay ironstone wdiich, however, on w^eathering, readily
