AT NAGPUR, &c. 201 



rough buildings, and the basement of the Palace, formed of the fine basalt 

 of SUdhaldi, neatly chisselled and very well put together, is surmounted 

 by an upper story of this poor gneiss. The unfinished wall of the 

 city is entirely of dressed basalt, at least externally dressed, and of the 

 best execution. Beyond the ridge of trap above noticed, at a very short 

 distance north, the decayed gneiss is again met with and quarried for the 

 roads ; but, in proceeding farther north, deep trap soil covers all vestiges 

 of rock, until we reach the granite of Waragaon and Surade. 



To the West, N. W. and S. W. trap entirely prevails ; to the N. E., 

 E., and S. E., black soil in the immediate neighbourhood, prevents the 

 observation of the underlying stratum ; but there is little doubt of its be- 

 ing gneiss, as this is the nearest rock displayed in those directions. 



KHORARI AND WARAGAON SPECIMENS. 



Nos. 1 and 2 (A) These specimens are from the hill of dolomite at 

 Khorh'i, distant from Sitdbaldi about six miles, and to the north of it. 

 The intermediate country is deep, black, trap soil. 



To the east is a low range of granite hills at Waragaon, the gra- 

 nite is remarkable for the great quantity of felspar in it — from its having 

 no mica, (or a very small quantity,) and the quartz being chiefly dispos- 

 ed in masses and exhibiting frequently large cavities lined with fine crys- 

 tals of quartz. To the west, Kltordn is bounded by the trap range, 



turning 



(A) Dolomite, large grained and very bard. 

 Fine-grained and friable Dolomites. 



Dolomites witb disseminated Steatite — with Tremolite, specks of Mica and veins of Calcedony. 

 Varieties named by Dr. Voysey, " Dolomite with disseminated Steatite and specks of Mica." 

 " Dolomite with veins of Calcedony."
