THE ALLAH-BUND. 2^ 



ture of the Chitichun area and adjoining portions of Hund£s have 

 been worked out more fully by a new exploration of this exceed- 

 ingly interesting country. I scarcely need say that it would be of 

 special interest and well worthy the expenditure of money and time 

 to further explore a territory exhibiting such peculiar structure. 

 For the present we must be satisfied with the discovery of the latter, 

 which had not previously been recognised in India, but must leave its 

 thorough explanation to our successors. 



A note on the Allah-Bund in the north-west of the Rann of 

 Kuchh, 1 by R, D. Oldham, A. R. S. M., F. G. S., Superin- 

 tendent, Geological Survey of India (with plate I.) 



All who have read Sir Charles Lyell's Principles of Geology will 

 be familiar with the account of the great earthquake of Kuchh in 

 1819, by which a considerable area of the Rann of Kuchh was 

 depressed, and a strip of land, known as the Allah Bund, was sup- 

 posed tohave been elevated. 



In 1872, the Memoir on the Geology of Kuchh, by Mr. A. B. Wynne, 

 of the Geological Survey of India, was published, 2 in which it was 

 argued that the Allah Bund was not in fact an elevated tract, but that 

 it merely had the appearance of such when viewed from the south, 

 and represented the comparatively steep slope connecting the 

 area which had been depressed from that which had remained un- 

 changed in level. This view was subsequently adopted by Professor 

 Suess, who threw over his original view that the Allah Bund was the 

 manifestation of a deep seated fold at the surface, 3 and in his Antlitz 

 der Erde unreservedly accepted Mr. Wynne's suggestion. 4 During 

 the recent move of the offices of the Geological Survey, a tracing of
