TOPOORAPHY OP THE PUNJAB OIL EEGKW. 



(copper glance), commonly covered with green carbonate of copper, from the size of a 

 walnnt down, are found in the npper part of the Devonian rocks of the Salt Kange ; 

 bnt no vein of the ore has been discovered. The ore is thought to contain fi'om 

 twelve to twenty per cent, of copper ; but to be insignificant in amount. 



10. Iron. — The ores of iron seem to be almost as small in amount at any one place 

 as the copper ore just mentioned. Small balls or crystals of magnetic iron ore from 

 the size of a walnut down, are found in a pebble rock at Aluggud through a small 

 space ; and similar bits of iron are found on the surface of the ground at Gunda, and 

 doubtless in many other places. But no place has been found to yield enough to 

 work. 



11. Lead. — Galena is found in small crystals in a limestone near the Keora salt 

 mines ; but is in such small quantity as to be worthless. 



YI. MAP. 



The Topography of the map that goes with this paper is based on that of Captain 

 (now Colonel) D. G. Robinson's admirable map of the Kohistan of the Sind Sagur 

 Doab, a map on a scale of one mile to the inch with the steepness of the slopes shown 

 merely by depth of shading, and with numerous levels marked in feet. 



As a difference Avill be noticed in the spelling of the same names in the paper and 

 on its map, it may be said that the spelling of the map is according to the rules of ro- 

 manized Hindoostanee (or for reducing Hindoostanee to Roman characters), a system 

 very convenient for maps, as comparatively brief, and showing the native pronuncia- 

 tion very perfectly, while the diacritical marks can be made in the manuscript without 

 trouble. On the other hand the spelling of the names in the paper is according to 

 the rules for anglicising Indian names, and is more convenient to print, from the ab- 

 sence of diacritical marks, and is more consistent with the rest of the text, and at the 

 same time shows passably the common English pronunciation of native words. 



The map is printed from a plate electrotyped direct from a photograph of the manu- 

 script by the process of Mr. Julius Bien, Superintendent of the J^ew York Lithogi-aph- 

 ing. Engraving and Printing Company.
