quartz-rock, and some jasper, with siliceous cement. Some of the 

 materials of this rock have been greatly squeezed, crushed, and 

 mylonized. 



If the strata of Section T be continued with the same strike as 

 that shown by the " conglomerate " band (which in Mr. Kyan's 

 plan of the Forbes Reef Gold-mining Company's property passes 

 obliquely across the Ingwenya Berg on the western side of the 

 summit. Fig. 1), through the Section T towards X, the strata T b 

 may be found in X G, and T a in X f, as the latter section trends 

 westward ; and, further, X d, o, b, and A continue the succession on 

 to the granite in the Transvaal. These beds in Section X (Fig. 3) 

 dip to the east, at a high angle ; and are evidently not only 

 conformably continuous with the " conglomerate " band of the plan 

 (that is, the breccia of T o, Fig. 2), but with the whole of the 

 great syncline.

A part of the eastern limb of the syncline is not represented by 

 specimens ; but in the general section (not given here) it is shown 

 to be more vertical, and consequently more compressed. Moreover, 

 it is immediately succeeded on the S.S.E. by a repetition of T b and
