NORTHERN WATERSHED OF THE TEEREE TOWEY BASIN. 93 



of these contortions is an oval, quaquaversal, dome-shaped sheet of the 

 nummulitic limestone, just south of and about a mile distant from 

 Sooddul (Sudul) village; but even this is faulted to the east, and sends 

 a narrow band of the limestone southward to join that of the main ridge. 

 The latter between this place and Shuwuki shows the nummulitic lime- 

 stone on its northern side as a boldly curving convex sheet descending below 

 the sandstones of the valley, but between this boldly curved sheet and the 

 dome -shaped hill, a portion of the limestone is absolutely inverted so as to 

 form a small cap upon a summit of the ridge which is mainly composed 

 of contorted tertiary sandstones and clays. Fig. 10 is a diagrammatic 

 sketch of the place from the dome-shaped hill, and Fig. 11, a section 

 south by west from Sooddul (Sudul) . —

The contortions necessary to produce this result are difficult even to 



imagine. If a second band of the nummulitic

limestone were admissible, it would make tkino's 

 easier to comprehend, but no such second band was observed in the vici- 

 nity, and where there are so numerous evidences of extreme contortion, 

 compression, and inversion in the district, it may not be too much to sup- 

 pose this, one more among many strange cases of the strata being over- 

 thrown. The cap is a very small one ; hence, perhaps, the difficulty of 

 connecting it with curvature of the adjacent beds, but it must be re- 

 membered that the distorting forces which have operated in this district 

 were sufficient to produce extreme results, and force the rocks into the 

 most anomalous positions.
