 Nagpur is 1000 feet above the sea. The city is mostly built on gneiss 

 and other metamorphic rocks ; overlying these is basalt, which forms 

 much of the country round. In 1864 there were 1231 wells in the 

 city, about 900 of which yielded brackish water. The city is now 

 supplied by gravitation works. W. T.

Compiled from the Official Reports. The rocks passed through, 

 according to Prof.Fritsch, are gneiss, mica-schist, and hornblende-schist, 

 with some crystalline limestone, and a little dolomite, gypsum, &c. The 

 beds have a fan -shaped structure, being vertical in the middle, at the 

 8. end dipping N., and at the N. end dipping S. Much water was met 

 with ; in some places it issued at the rate of 3000 gallons a minute. 

 Details of methods and rate of work in various rocks are given, and 

 observations on the temperature. W. T.

The Dunes of Gascony are nearly 120 miles long. The sand formerly 



advanced towards the interior, but is now fixed by plantations of sea 



pines. The general height of the Dunes is from 160 to 230 feet; but 



near the middle of the chain some arc 300 feet high. W. T.
