intervals, a small party of soldiers, with a troop of horses 

 (a posta), so as to be enabled to keep up a communication 

 with the capital. As the Beagle intended to call at Bahia 

 Blanca, I determined to proceed there by land ; and ulti- 

 mately I extended ray plan so as to travel the whole way by 

 the postas to Buenos Ayres. 



August 11th. — Mr. Harris, an Englishman residing at 

 Patagones, a guide, and five Gauchos, who were proceeding 

 to the army on business, were my companions on the jour- 

 ney. The Colorado, as I have already said, is nearly eighty 

 miles distant : and as we travelled slowly, we were two days 

 and a half on the road. The whole hne of country deserves 

 scarcely a better name than that of a desert. Water is found 

 only in two small wells : it is called fresh ; but even at this

 a tribe of Indians come in sight of it, they offer their 

 adorations by loud shouts. The tree itself is Iom^, much 

 branched, and thorny. Just above the root it has a diame- 

 ter of about three feet. It stands by itself without any 

 neighbour, and was indeed the first tree we saw ; afterwards 

 we met with a few others of the same kind, but they were 

 far from common. Being winter the tree had no leaves, 

 but in their place numberless threads, by which the various 

 offerings, such as cigars, bread, meat, pieces of cloth, &c..
