lined cavities. There are red blotches on the surface due to 
oxidized iron. 10 feet. 
24. Interbedded black and white chert and shale layers, with 
one irregular limestone layer about four inches in thickness. 
The bedding is more distinct towards the bottom where jointing 
becomes abundant. There are several waved surfaces. Calcite 
veins and nodules with large pseudomorphs of limonite. 
5 feet. 
25. Several grayish, dense, limestone layers of less than two 
feet each in thickness. The upper layers, on weathering, bring 
out the thin bedding. There are also thin partings of light, cal- 
careous shale. Joints are rare and irregular. Red blotches and 
threads, with little calcite and no chert. Fossils seen about half 
way up the unit. Limonite pseudomorphs. 11 feet. 
26. Blue, heavy bedded, medium crystalline limestone with 
definite layers and chert nodules. Some layers are siliceous but 
not sandy ; the main beds, six in number, show minor beds on 
weathering. There are several small shale partings and one fer- 
ruginous, flinty parting which is cross-bedded. There is also a 
one foot calcareous, shale layer seven feet from the top. 
47 feet, 
27. A faulted zone with slickensides common. Most definite 
fault is the southern and has a dip of fault plane about 67°N 89° 
W. Strike is therefore N 1° E. Two or more major faults 
occur to the north of first one but the dip and strike and amount 
of displacement are not determinable. This is a brecciated zone 
of greatly smashed and distorted strata. Probably 103 feet. 
28. (We are now on the wagon road, having been on the rail- 
road up to this point) . Heavy bedded, bluish grey, finely crystal- 
line limestone with layers and nodules of white and light blue 
chert, some layers of which are 2 inches thick and single nodules 
6 inches across. There is little jointing but there are calcite 
bunches. The top of the unit is wave marked with crests three 
feet apart, with a shaly parting at the surface. Weathers red 
and rusty. 27 feet. 
Wave markings and shale partings may mark change in con- 
ditions and life, but there seems to be no change in dip or strike 
and little change in the lithological phase of the rocks. The wave 
marks and crests trend N 15 to 20 degrees E.
