PART I. 



GENERAL DESCRIPTION. 

 CHAPTER I.— INTRODUCTORY. 



The area to be described in the present memoir comprises that 



portion of the province of Sind or Sindh 1 which 

 Area described. 



lies west of the Indus, and especially the hilly 



portions of the Karachi and Shikarpur Collectorates, together with the 



curious isolated ranges of limestone hills to the east of the Indus in 



Northern or Upper Sind near Rohri, and in Southern or Lower Sind near 



Hyderabad. Eastern Sind, and especially the district of Thar and 



Parkar, lying north of the Ran of Kachh (Cutch), has not yet been 



examined in detail. 



Before proceeding with the description of the province of Sind, a 

 few words are necessary to show how important is an accurate knowledge 

 of the geology as a guide to that of other parts of British India. 



It is unnecessaiy to recapitulate here what has been explained fully 



1 The names of the province of Sind and of the river called the Indus by Europeans, 

 are really identical ; and Hindu, Hindustan, and India itself are all derived from the same 

 source, the letters S. and H. being interchangeable, and the last frequently disappearing 

 in the process of representing Oriental names by European equivalents. The old name 

 of the Indus is Sindhu. There is a Muhammadan story about the name of Sind being 

 derived from Sindh, the brother of Hindh and son of Noah.
