GEOLOGICAL SURVEY 



Mr. King paid the Wynaad a second visit, but of very short 

 duration, in 1878, and published his notes of the same in the 

 records for August of that year. 28 In 1880 Mr. King 

 visited Pondicherry and reported on the artesian wells sunk 

 at that place, and gave a rather favorable opinion on the 

 probability of similar borings meeting with success at 

 Cuddalore and Madras and at other places situated on the 

 coast alluvium. 29 



The author's work in the Nellore and Kistna Districts 

 occupied him during three field seasons, from 1874 to 1877, 

 and the results were embodied in a Memoir " On the Geology 

 of the Eastern Coast from Lat. 15° N. to Masulipatam." — 

 (Memoirs of the Geological Survey of India, vol. xvi, part i, 

 1879). 



The points of special interest here met with were (1), the 

 settlement of the non-volcanic character of the Boggola- 

 konda, a conspicuous black conical hill south-east of Vinu- 

 konda in the Kistna District, which had often been asserted 

 to be the centre from which emanated the generally slight 

 earthquake shocks so common in that quarter. 



(2) The existence of three important series of rich magnetic 

 iron-beds — one at Ongole, one north, and another south of 

 that town — the first being so situate that its ore could be 

 easily and cheaply conveyed to the East Coast Canal or else 

 the sea at Kottapatam. 



(3) The discovery of very richly fossilif erous marine beds in 

 the Upper Grondwana (Rajmahal) outliers to the north-east of 

 Ongole. Outcrops of these beds had been noted by the late 

 Mr. C. 2E. Oldham while making a traverse from Gruntur to 

 Ongole at Tangelamudi, Inkolu, and Eazpudi, and were
