Emerson — Carboniferous Bowlders from India. 57 



Art. YII. — Carboniferous Bowlders from India ; by B. K. 



Emerson. 



Lsr the spring of 1894, I was in the office of the Geological 

 Survey of India and Dr. Fritz Notling unpacked for me and 

 explained a fine series of the bowlders of the Carboniferous 

 Glacial period of the Salt range in northwestern India. 



They had been obtained partly from the talus and partly 

 from the conglomerate itself, and he was kind enough to give 

 me samples of the different forms. Later, Dr. King, the 

 Director of the Survey, observing the unconscious but silent 

 admiration with which I examined the finest bowlder of the 

 series, packed it up and sent it after me to my lodgings. This 

 is the largest bowlder in the figure and is 10 inches long. 



It is a dark red rock halfway between a granite and a quartz 

 porphyry and is perfectly scratched on four sides and rough 

 and battered on the ends. 



It is in color, shape, and kind and perfection of striation, 

 so like the great bowlder, about 9 feet Jong, of reel sandstone 

 which stands in front of the Geological Museum at Amherst 

 and which was taken from one of the streets at Amherst dur- 

 ing the lowering of the latter, that I may cite a figure of the 

 latter for comparison from my monograph of old Hampshire 

 Co., Mon. xxix, U. S. G. S., pi. xxxiii, p. 192. 



The bowlder with the cord around it was broken in dislodg- 

 ing it from the ledge and shows remains of the conglomerate 

 cemented onto its upper surface. The bowlder on the small 

 box is scratched on several small facets separated by sharp 

 crests and has also fragments of the conglomerate attached.
