THE PICTOU COAL FIELD— POOLE. 265 



stones containing calaniites and stignmria roots have a clip 

 of N. 10° to 35° E. with a dip of 40' increasing lower down 

 the brook to 60°, and 65° at the turn in tlie brook where an 

 older mill was situated, and here tlie rocks have an inclination N. 

 10° W. and include beds of grey conglomerate. 



How far north the Lower Carboniferous extends towards the 

 Acadia pit has not been determined, but the color of the soil 

 being redder on the range than on the flanks may indicate an 

 extension for some distance in that direction. 



The great extent of conglomerates and false bedded sand- 

 stones seen at McDonald's mill site on the same brook suffSfests 

 that these beds are basal and closely overlie an older formation 

 which has not been exposed. The section No. II given in the 

 Report begins at McDonald's mill dam with coarse conglomerates 

 interbedded with sandstones. Some of the lower of these inter- 

 bedded sandstones contains numerous remains of plants with 

 roots and rootlets. The dip is about N. 10" W. 40°, which is 

 continued for 600 feet down the brook, and when the highest of 

 the conglomerate beds is past the inclination is found to be N. 

 40° E. 30°. This dip and direction appears to be the average 

 for some distance along the main brook and in a lateral branch 

 from the east. Although exposures are numerous it is difiicult 

 to get the correct average inclination as there is much false bed- 

 ding To what extent the rocks of this section have been 

 repeated by faults has not been made out, but it is probable that 

 the series of faults proved along the crop of the Acadia seam 

 extending over to French's tunnel are continued. Certainly 

 there is a fault of some moment passing under Squire McLeod's 

 house where the brook crosses the Middle river road. 



The valley of the Midd'e river aflbrds the I est exposures of 

 these rocks, alternating beds of dull red sandstones too much 

 cleaved to supply good building stone, and argillites having a 

 characteristic mottled appearance. At French's tunnel the coal 

 measures weatlier a yellowish grey, a colour which gives place to 

 reddish tints at the higher turn of the river where beds of coarse 

 red conglomerates are seen. These beds 8 and 3 feet thick and 150 

 yards apart are not readily distinguishable from the heavy beds
