‘ashes.’—Concretionary shales.--Band of ferruginous chert beds.—Lime- 
stones,— Upper band of—Silicio-felspathic bands or felsites—Have pro- 
duced no alteration in contact beds.—Trap flows.—Character of rocks.—Con- 
temporaniety.x—Two periods of volcanic energy.—Lie of traps with other 
strata.—Flows tailing in over one another.—Faint indications of volcanic 
centres.—Intrusive trap of Beddadoor hill.—Considered generally, the traps 
are mostly contemporaneous, partly intrusive.—Southern representatives of 
Tadapurtee series—Poolumpett slates.—Character of—Clay slates.— 
Two bands of limestone.—Sands, flags, and cherts.—Lie of strata to the east, 
obscure.— Eastern line of faulting.— Character of limestones.— Breccia beds.— 
Peculiar silieious beds.—Signs of unconformity.—No similar limestones in 
the Tadapurtee field.—Similar beds in Baukrapett hill east of Cudda- 
pah.—Possibly also Poolumpett oan dán im ... DS P 
CHAPTER 4.—The Nullamullay Beds.—Poolumpett slates are overlaid uncon- 
formably by quartzites of Byrenconda mountain. Seeming representatives in 
the Kistnah Nullamullays.—In the Yellaconda ridge.—In the Gundycotta 
range.—Character of strata in Polleonda.—Kaukuleonda fault.—The mid- 
ridges south of the Chey-air.—Unconformity.—Crushed-up strata.—Southern 
extremity of the series obscured by faulting.—Nullamullay field.— Yellaconda 
beds, Mr. Foote's notes.-—Stratigraphy not clear.—B y ren con da outcrop to- 
wards Muntaral Cunnama.—Apparent break in the north-easterly extension of 
strata.—Style of Gundycotta beds.—Inliers.—Cumbum  slates.—Byren - 
condas overlaid by slates.— Extent of slate series.— Strata vary much.— 
Folding.—Intercalated bands of quartzite.—' Thickness of Cumbums.— 
Character of slates.—Intercalations of limestone.—Often very similar to those 
of KARNULS.—Limestones of the Penn-air.—In Baukrapett hill.—Signs of 
faulting,—Obscurity at  Nundiallumpett.—Hotcomudgoo  faults.—Down- 
throw to the south.—Limestones in the Cumbu ms metalliferous.— Regions of 
quartz suffusions.—No minerals of value in these.—Mr. Foote's notes on the 
Cumbums e ise ae 3. 24 ... 212—240 
CHAPTER 5.—Quartzites overlying Cumbum slates.—Soutlhern part of Yella- 
condas.—In  Byrenconda.—In the Kistnah Nullamullay.—Indications of 
unconformity in the Kistnah region.—Southern Yellaconda beds.—Thick- 
ness.— Eastern edge concealed by talus.—Faulted.-- Northern part of Yella- 
eondas.— Possible inversion of strata.—Or a system of faults.— Breaks in 
continuity and character of strata between Cumbum and Kullsapad.—Nemilly- 
- goondum quartzites.—Giddaloor outlier.—Nundicunnama and Howhoblum,— 
Nemillygoondums seem to answer to Yellaconda beds.—Higher slates of 
Aukiveed.—The Kistnah Beds.—Strata on the Kistnah.—Obscure stratigraphy 
of Dorenal valley.—Kistnah Beds overlie Cumbums.—Traverse of south- 
south-east slopes.—Unconformable to Cumbums.—Sreeshalum plateau,— 
Quartzites.—K olumnullah slates.—Irlaconda quartzites.— Great thickness
