SoMK ISoTEs ON Uni)KH(;i{ound Water. 135 



Dining the piogress of boring at Moitiuier station some ga.s was 

 struck at a depth of 105 ft., and proved inflammable. None wan 

 collected for e.vamination, and there seemed to be only sufficient to 

 make the water lively when it rose in the bore-hole. 



It appears fn>m the results that the indurated bluish shale alter- 

 nating with sandstone gives promise of good wattn-. The water at 

 Willowmore proves in practice not good for locomotive purposes ; the 

 shale at ^\'illowmore is nearly as dark as at Vondeling, where the drill 

 foreman described it as black ; both are in Bokkeveld beds. Red and 

 grey, or blue marl, Uitenhage beds, is evidently heavily charged with 

 salts, as are most of the heavy claj^s of South Africa ; see analyses of 

 water at Uitenhage, .Sandflats and Glenconnor. In the Stormberg 

 lH>re-hole, however, which is beside the Stormberg-Rosmead line, the 

 red shale and clay, which one would expect to be " brak," proved to 

 have fairly good water infiltrating through or confined below. 



Where dolerite has been pierced, in the hopes of getting a supply 

 below, the results have varied. At Bedford station there is practically 

 no water either upon or below the dolerite, while at Aberdeen Road a 

 good supply was obtained below a bed of dolerite. 



In all cases the bore-hole is continued for 8 or 10 ft. below the 

 point at which the maximum amount of water is entering the hole, as 

 a sump below the pump. Boring was done by drills, the property of 

 the Railway Department, under direction of the engineers. 



The analyses of water were made by the Analytical Department 

 of the Government at the instance of the Engineers Department of the 

 C.G.R. Analyses of some natural springs near the railway are given, 

 in addition to the bore-hole waters.
