160 OBSERVATIONS ON THE GEOLOGY OF THE 



Wolves, or wild dogs, (for I had no opportunity of judging which), 

 are found in the forests. No jackals, or common foxes, have yet been 

 discovered, and, it is believed, that they do not exist below the latitude 

 of 19° north. Many kinds of tortoises, as before observed, and river 

 turtle, were seen by me. The natives, especially the Kariaus, train dogs 

 to search for them, as they form often a chief article of their food. 



The birds are : — White sea eagles, white land eagles, hawks, of 

 several species, vultures, and kites. 



The peafowl here exhibits a brilliancy of plumage, which far excels 

 that of the Indian one. It is also a larger bird. There are, at the least, 

 four elegant varieties of the pheasant tribe ; also, quails in abundance ; 

 and several kinds of partridges, of which the green, with a red tuft, 

 and the blue, are most conspicuous. There is, likewise, a jungle cock, 

 having a rich blue and reddish plumage, and nearly twice the size of the 

 common jungle fowl. He is well armed with two long spurs on each 

 leg. Pelicans, and the usual tropical water- fowl, abound. A perfect 

 species of duck, having a blackish back and whitish breast, and the 

 weight of which is nearly double that of the common duck, is very 

 common . 



Leaving the 3Iichan-tdng, and proceeding up the Sanlun river, the 

 low rocks, observed on the banks, exhibit coarse black limestone. The 

 high cliffs further removed, shew the more advanced stage of the lime 

 formation. At jfiTa iTrtye^ stockade, close to the hills, the granite again 

 begins ; and here were found scattered about smooth quartz and other 

 pebbles of several pounds in weight, which had been used after their 

 ammunition had failed by the Surman garrison when defending themselves 

 from the attacks of the Siamese ; — baskets, full of these pebbles, were 



arranged
