THIS publication contains miscellaneous notes and observations 

 made by Officers of the Geological Survey of India. 



Coal at Chenda.—^lx. W. T. Blanford, F.G.S., having been en- 

 gaged in examining some coal seams discovered in the neighourhood 

 of Chenda, here furnishes a report on the prospects of the coal being 

 profitably mined. He states that although one seam is very pro- 

 mising, some further research is necessary before a decisive opinion 

 can be formed upon this subject. 



Dr. Oldham adds that borings have been carried out close to the 

 town of Chenda, and have proved the existence of coal, about 2 ft. 

 6 inches in thickness. The coal is said to be hard, but as no trial of 

 it has yet been made, its quality is unknown. 



Coal near Nagpur. — Mr. Blanford reports on the likelihood of coal 

 being found near Xagpur. Although it is probable that the sand- 

 stones developed in the neighbourhood belong to the Indian coal- 

 bearing series, yet he has been unable to obtain any indications 

 of coal. 



By far the greater portion of the beds of this series in Xagpur 

 are concealed by thick alluvial soil, and it is therefore impossible to 

 say whether coal exists beneath it. or not. Mr. Blanford, however, 

 points out a few localities where its presence is just possible, in 

 order that, if advisable, borings may be made to determine the 

 question. 



Geological Notes on the Surat Collectorafe, (Bombay Presidency). — 

 Mr. A. B. Wynne, F.G.S., gives a general account of the Physical 

 features and of the formations constituting this Collectorafe, and he 

 then furnishes some detailed notes on the rocks in various localities. 



Taken generally the district may be described as flat, with isolated 

 hills on the south, and bordered on the east by a hilly and 

 jungly tract. 



The formations which occur are —

The trap-beds consist of many varieties, ranging from solid 

 basaltic trap to soft shaly-looking amygdaloid, the variously sized 

 cavities of which are filled with zeolites of different kinds, and 

 sometimes by transparent or amethystine quartz. 



Besting unconformably upon the traps is to be seen a series of
