and hornblende ; further oh, pure hornblende appears, and within 
three miles of Mysore, an extensive stony plain is passed over, 
consisting chiefly of small fragments of the rocks already men- 
tioned, but also of small irregular masses, of what, from its weight, 
I take to be a very pure magnetic iron. The compass within 
which this ore is found strewed does not exceed a few miles ; pro- 
bably some vein or bed runs through the rock below. From Mysore 
to beyond Muddoor I travelled at night, but from this to Chinna- 
patam, the rocks begin to assume that variegated appearance, which 
a mixture, sometimes in masses, but generally in contorted layers of 
hornblende, quartz, mica and felspar produces. A little before arrival 
at Closepetta, a rock juts up by the side of the road, which, though 
not above two or three yards broad, contains perhaps a hundred of 
these alternations, some so distinct as to be called veins of quartz ; 
others differing but slightly in colour from the layer next them ; 
some parts of this rock contain garnet. In general, these strata are 
very much inclined, but some are twisted into numerous serpentine 
directions. As we advance beyond Closepetta, the hills close near 
us. These are all very abrupt and perpendicular, though with 
rounded tops ; their sides do not present sharp ridges and furrows ; 
they are of a smooth form, but too steep to admit of the formation 
of a soil. I took specimens from immense fragments and boulders 
near their feet ; and these were all of a coarse sienite, in which the 
crystals of felspar were very large, and the hornblende distinct. 
The former was generally of a reddish hue, but it was sometimes 
white, and passed with the hornblende into a greenstone, while 
through this again, veins of quartz ran. In the variegated rock 
mentioned above, whole masses of hornblende were visible. I am 
inclined to think that all the high mountains of Mysore are of this
