is found, which, from the base, covers the low hills and knolls westerly 

 to Vyathoor. 



Stony River : foot of Heggulla pass.— In the bed of this river lie 

 large irregular blocks of massive hornblende rock with garnets, and a 

 granite with both mica and hornblende, evidently rolled down (like 

 those on the slope of the pass,) from the adjacent heights. The horn- 

 blende rock is usually crystalline, but there occur globular masses of 

 compact basaltic greenstone, with needle-shaped crystals of augite 

 shooting irregularly through its substance ; those probably are from 

 some large dyke in the vicinity. The garnet occurs both massive, 

 dodecahedral, and semi-foliated ; the last is the most common variety. 



Vyathoor. —The Coorg frontier is crossed into Malabar, close to the 

 Stony river, from which the first Malabar village, Vyathoor, is about 

 five and a half miles distant, and about twenty-nine and a half miles 

 inland from Cannanore. The adjacent country is rocky, and covered 

 with jungle : laterite continues capping the granitic and hypogene 

 rocks, principally granitic hornblende schist. The beds of the mountain- 

 streams abound with fragments of garnet. I found none of the crystal- 

 lized specimens of any magnitude. Magnetic iron-sand also is found 

 in their beds in small quantities. The Moplay town of Ercoor lies 

 about eleven miles farther, on a fine clear stream, called the Rokaat, 

 which debouches near Mount Delli at Markaree. The houses have 

 upper stories, are built of laterite, and have a remarkably substantial 

 and neat appearance. 



Cudully. — This place is about ten miles inland from Cannanore. 

 The surface of the country is rugged and uneven, with low hills and 

 cliffs of laterite, and still covered with luxuriant jungle. In many 

 places the jungle has been fired, leaving the black precipitous tabular 

 masses of laterite, which cap them, exposed. The hornblende schist is 

 still seen in low situations. Black pepper, betel and rice, are exten- 

 sively cultivated. 



Cannanore.— -Nearer Cannanore, passes are cut through high cliffs of 

 laterite, and steps planed down the sides of the terraces, which descend 

 towards the sea coast. Hornblende schist veined with quartz is still 

 seen as the underlying rock. At Cannanore, the laterite terminates in 

 high, sea- washed cliffs.
