THE PICTOU COAL FIELD — POOLE. 329 



No. 2 near the south-west corner of the Vale area, and No. 3 on 

 Marsh brook some 15 chains from its mouth, both cut strata of 

 the same horizon as the later borehole from the McLeod pit in 

 1889. 



Besides the opening on the George McKay seam three slopes 

 were put down near the Marsh pit on the Captain seam, and their 



•direction indicates a curving round to the east of the crop of 

 this overlying seam. The slope nearest to the pond went down 

 some forty feet, the next dipping N. 50 E. 14'^ some 110 feet, and 

 the most westwardly N. 40^ E. for some 80 feet. The irregularity 

 in the direction of the slightly inclined strata to the east is con- 



. sidered due to rolls, and not to faults. 

 • Tke Vale Section. — This includes the St. Lawrence and McBean 



.areas of Logan and the ground adjacent to the west. It contains 

 a syncline of which a fork runs into the Marsh pit section. The 

 main syncline extends westward along the base of McLellan's 

 mountain under McLellan's brook to the eastern foot of McGre- 



.gor's mountain. In sections numbers G, 7, 8 and 9 of his report, 

 Logan gives a record of some of the measures that dip towards 

 the northwest. These sections require some readjustment due 

 to information since obtained by the veteran explorer of this 

 locality, Mr. A. McBean, but the records here given are still very 

 incomplete and far from accurate. The bottom of the syncline in 

 the Vale area is approximately under Marsh brook in its coui'se 

 before it is deflected westward by the high ground on the bor- 

 ders of the North fault. The axis of the syncline dips eastward 

 and as it proceeds the fold is sharper, the legs dip at higher and 

 higher angles and are more disturbed by cross faults. These 



•cross faults are upthrows to the east and increase in strength as 

 they approach the axis. In the extreme eastern corner, the St. 

 Lawrence area, the ground is so disturbed that little hopes are 

 entertained of the finding of patches of workable coal, though 

 among the faults of the east end of the Vale area there is a piece 



•of unwrought good coal but it is steep. Sir William discusses at 

 the foot of page 42 whether the fault that there disturbs the 

 seams is an upthrow or downthrow. Every member of the series 



•■of faults in that locality disclosed since 1869 has been found to
