DETAILED ACCOUNT OF SOME RECENT EXPERIMENTS. 73 



If a bore-hole were sunk 7 or 8 miles north east of Wadhwan, for 

 instance, it would probably encounter the following series of beds 

 in succeeding order : — 



1. Alluvium, probably 10 to 20 feet. 



2. Tertiary limestones and marls, — some 40 to 60 feet. 



Upper Water-level. 



3. Unknown strata, probably of tertiary age and of unknown 

 thickness. 



-4. Upper cretaceous limestones and marls. 

 5. Brown sandstone, cretaceous or Jurassic. 



Lower Water-level. 



6. Unknown strata below. 



It will be seen therefore that water wouid certainly be obtained 

 by boring, and it may be that by driving the boring down to the 

 lower water-level indicated above, artesian conditions will be en- 

 countered. The proposition appears to me hopeful, and I would 

 suggest that such a bore-hole be constructed of at least 1,000 ft. 

 depth in the neighbourhood, say, 7 miles north-east of Wadhwan. 



(8) Experiments made in former years, and the experience 

 gained in well sinking, have proved that water may be obtained 

 almost everywhere in Gujdrat, — although in varying depths. It 

 appears also, that much of the water-supply from wells is more or 

 less brackish and becomes often unfit for either drinking or irrigation
