 ness j the shales being of purple or chocolate color and the limestone 

 pale-bluish or greenish-white. These are largely displayed in the two 

 streams draining the slope east of Mannagarh (Munnaghur) . In the 

 lowest part of the bay near the banks of the big nullah at Hungurgee 

 these shaley beds are overlaid by grey and drab limestones, the beds of 

 which are much crumpled. 



At Kakkalgaon, three miles north-west by north of Kattigiri 

 (Kutteegeree), are banded grey, greyish- white, and whitish limestones, the 

 latter associated with purple-grey clay rock. 



At Hulgiri (Hoolgeeree), twelve miles south-east of Kaladgi,agreat 

 number of beds crop up north-east of the village, showing nearly as 

 great a variety of colors as the Bagalkot beds. 



To the eastward of Kaladgi and north of the Ghatprabha, to the 

 north of the Arrakeri syncHnal valley, is a great

portions of the beds. Much of the calcareous matter has been removed 



by atmospheric agency, and the surface of the country is greatly marked 



by chert debris. The more calcareous beds are best seen along the Shola-

no trace of the great volume of excavated materials which must have 



been piled somewhere had the excavation been made by human agency. 



This lake is of interest, as being the only natural one, as far as my 

 knowledge goes, in Southern India.* It is small in size, not more than 



* There is one other reservoir of fresh water which I should unhesitatingly regard as 

 a true lake if glacial phenomena were admissible in the Peninsula of India. It is a small 

 sheet of water lying at a considerable elevation in the southern ghats west of Courtallam 

 in a coffee estate belonging to Mr. Roosmale-Cocq of Tuticorin; the bund which retains this 

 very jiicturesque pool strongly resembles an old moraine.
