gratory birds, such as the swallow, the cuckoo, and others, had again made their appearance.
The animals, which during the dry season are compelled to gather round the springs and other permanent waters, were enabled, by the late rains, to scatter themselves over a large extent of country, and were now difficult to find. There can be little doubt that the instinctive power of animals—domesticated as well as wild—is capable of catching the scent of humid winds and green herbage at a very great distance. Thus I have often seen oxen turn their heads toward the quarter where distant lightning indicated that rain had fallen, and sniff with evident pleasure the breeze produced by colder air. Mr. Moffat, the missionary, mentions an instance where a great number of cattle were entirely lost, solely, as he supposes, from this cause.
"Many years previous to my sojourn in Namaqua-land," says the reverend gentleman, "Afrikaner thus lost the greater part of his cattle. One evening a strong wind commenced blowing from the north; it smelt of green grass, as the natives expressed it. The cattle, not being in folds, started off after dark. The circumstance being unprecedented, it was supposed they had merely wandered out to the common, where they were accustomed to graze; but it was found, after much search, that some thousands of cattle had directed their course to the north.
