After breakfast, some of the men, who had gone forward on a little path with some footprints of water-loving animals upon it, returned with the joyful tidings of "metse", water, exhibiting the mud on their knees in confirmation of the news being true. It does one's heart good to see the thirsty oxen rush into a pool of delicious rain-water, as this was. In they dash until the water is deep enough to be nearly level with their throat, and then they stand drawing slowly in the long, refreshing mouthfuls, until their formerly collapsed sides distend as if they would burst. So much do they imbibe, that a sudden jerk, when they come out on the bank, makes some of the water run out again from their mouths; but, as they have been days without food too, they very soon commence to graze, and of grass there is always abundance every where. This pool was called Mathuluani; and thankful we were to have obtained so welcome a supply of water. After giving the cattle a rest at this spot, we proceeded down the dry bed of the River Mokoko. The name refers to the water-bearing stratum before alluded to; and in this ancient bed it bears enough of water to admit of permanent wells in several parts of it. We had now the assurance from Ramotobi that we should suffer no more from thirst. Twice we found rain-water in the Mokoko before we reached Mokokonyani, where the water, generally below ground elsewhere, comes to the surface in a bed of tufa. The adjacent country is all covered with low, thorny scrub, with grass, and here and there clumps of the "wait-a-bit thorn", or 'Acacia detinens'. At Lotlakani (a little reed), another spring three miles farther down, we met with the first Palmyra trees which we had seen in South Africa; they were twenty-six in number. The ancient Mokoko must have been joined by other rivers below this, for it becomes very broad, and spreads out into a large lake, of which the lake we were now in search of formed but a very small part. We observed that, wherever an ant-eater had made his hole, shells were thrown out with the earth, identical with those now alive in the lake.
