We passed several little rivers on their way eastward to join the 

 Manjira. An explanation of the cause of the total absence of trap on 

 some of the hills must still be sought for. 



Thursday, Wth February, 1819. — Through the continuation of the 

 plain to which Beechicondah is the pass. For some distance granitic 

 sandy soil, when a river produced its usual accompaniment the black 

 cotton soil of the trap. We passed Mudnoor at the back of which to 

 the N. E. the granite commences surmounted by the trap. As we 

 crossed the fields and ascended the hills of Bukutapoor, calcedony with 

 green-earth, heliotrope, amygdaloid wacke, with zeolite, stilbite, and 

 carbonate of lime coloured green, were found in great abundance and 

 very fine specimens. 



The western side of the hill on which we are encamped is composed 

 of the crystalline transition greenstone, but in the vallies and towards 

 the eastern side it consists of wacke enclosing large specimens of foliated 

 zeolite or stilbite with amygdaloidal pieces of green-earth, which has 

 given its colour to carbonate of lime also contained in it. The wacke 

 is of a greenish grey colour and is destitute of crystals of olivine or of 

 basaltic hornblende. 



Friday, \2tk February, 1819. — I visited a ravine about a mile due 

 east of the hill, in which the trap was much water-worn. In one part 

 it had very much the external appearance of the Rowley Bag Basalt 

 described in Thomson's Annals, being semicolumnar. In another 

 part, it consisted of nodular concentric masses of which the external 

 coats were decomposed, leaving rings around a lump of more compact 

 nature undecomposed, on others a number of concentric circles visible of 

 various sizes, according to the quantity of the mass decomposed. 



Our servants have brought in a number of very haudsome speci- 

 mens of 



Wacke contg. Foliated zeolite. 



Ditto Green earth. 



Ditto Green carbonate of lime. 



Ditto Nodular mesotype, heliotrope. 



Ditto with green-earth and calcedony. 



Ditto with Jasper ditto ditto. 



Saturday, 13£A February, 1819. — The surrounding hills and accli- 

 vities are of two descriptions. The lowest are of granite, are rugged,
