No. XL VI.— NOTE ON SUBMERGED TREE STUMPS DISCOVERED 

 IN BOMBAY HARBOUR. 



( With an illustration.) 



In a paper published in our Journal, Vol. V, No. 2, 1890, entitled 

 " Prehistoric Bombay " by W. E. Hart, an account is given of the various 

 evolutions of nature that took place before our present Bombay as a single 

 Island, to quote Mr. Hart's words, "rose, as did of old, the Goddess of 

 Beauty from the sea." 



To shortly summarise Mr. Hart's paper, he deduces from the evidences of 

 marine and land fossils in the deposits on the flats and at Byculla and the 

 discovery of a submerged forest in the excavation of Prince's Dock, that 

 after the various flows of the trap had completed the general formation of 

 this portion of Western India, an area of some 1,000 square miles, including 

 what is now Bombay, broke off from the Coast and was submerged in the 

 sea ; and that subsequently in the area that includes Bombay there were 

 at least 2 upheavals and the subsequent subsidences, the last of which left 

 Bombay as a succession of Islands which were eventually joined together 

 by the silting up of the deposits brought down by the neighbouring creeks. 



The purpose of the present note is to place on record the finding of some 

 additional trees in somewhat similar circumstances to those mentioned in 

 Mr. Hart's paper, as having been found by Mr. George Ormiston in the 

 excavation for the Prince's Dock. Mr. Ormiston states that he discovered 

 some 400 trees, 223 of which were still standing at a depth of about 32 

 feet below high water. Of those fallen several showed signs of having 

 been burnt, from which he deduces the presence of man. 



The trees or rather tree stumps discovered during the excavation for 

 the New Docks were only 4 in number, 3 of which were standing. Their 

 position is nearly half a mile from what was a few years ago the foreshore
