Passage Beds. ■{ 



Estheria Shales. Thickness 638 feet, including 

 the cupriferous shales and tuffs. Three hundred 

 and sixty-seven feet chiefly fine-grained green- 

 ish-grey sandstone with pebbly-bands and a 

 little fine conglomerate, gi'eenish-grey indurated 

 clay shale and dark grey mudstone. 



Seventy-one feet clay shale and mudstone, 

 dark reddish-purple slightly mottled with green, 

 passing towards the base of the beds into dark 

 greenish -purple and bluish - black tuffaceous 

 shale and seven inches of tuff. 



Two hundred feet greenish-grey carbonaceous 

 sandstone with beds of tine conglomerate 10 feet 

 to 28 feet thick, containing pebbles of grey 

 f el site, and black, red and green jasper, and 

 indurated greenish-grey clay shale. 



Valves of a species of Estheria were found 

 by me at depths of 1,362 feet, 1,627 feet, and 

 1,651 feet, and subsequently by Mr. W. 

 Anderson, at depths of 1,963 feet and 2,000 

 feet.

Thickness proved 307 feet at least. Chiefly sandy-clay shales, 

 dark grey, cai'bonaceous, with frequent bands of fine grained clayey-

 mencement of these beds ; and thin ferruginous bands at twenty- 

 eight-feet above the first coal seam, hard quartzose-sandstone and 

 clayey-carbonaceous sandstone, and five feet eight inches of fine 

 conglomerate.
