Saturday, 20th February, 1819. — I passed through the village of 

 Mengoor near which, on the banks of a . small nullah, the thermo- 

 meter sank to 47° just before sunrise : in its neighbourhood, I also saw 

 a bed of lithomarge lying on the alluvium which rested as usual on the 

 trap. The fields on my right and left were full of gram and corn 

 crops ; nevertheless I observed that a large quantity of land had been 

 thrown out of cultivation. The approach to the Godavery was over 

 waving land consisting entirely of trap and alluvium ; now and then 

 beds of amygdaloid with green earth and wacke were seen, and within 

 a mile of the river small blocks of granite rising through the alluvium, 

 so rounded, that I found it impossible to bring away specimens. My 

 visit to the rocks was first paid ; I found them to consist of granite 

 forming the banks and bed of the river, the former were about 40 feet 

 high ; of this height the granite occupied one-half and the remainder 

 consisted of black cotton soil ; the river was shallow indeed. I crossed 

 its deepest part, and found it vary from 2 to 4 feet in depth, its bed 

 consisting of granitic sand mixed with a few calcedonies and agates, and 

 on the borders magnetic iron sand ; I did not see shells. In the crevices 

 of the rocks I found some pieces of stilbite or radiated zeolite. The 

 height to which the river rose two years ago, was pointed out to me, it 

 might be about 30 feet above its present level : it had washed away the 

 corner of a wall surrounding a handsome pagoda built of black basalt :
