Now, as they resumed their way, the trees altered and drew farther apart, the ground was solid under foot, and through the foliage of the euphorbia and raphia palm came stray glimmers of sunshine, bits of blue sky, birds, voices, and the whisper of a breeze.

“This is better,” said Berselius.

Adams flung up his head and expanded his nostrils.

“Better, my God!” said he; “this is heaven!”

It was heaven, indeed, after that hell of gloom; that bog roofed in with leaves, the very smell of which clings to one for ever like the memory of a fever dream.

All at once patches of sunlight appeared in front as well as above. They quickened their pace, the trees drew apart, and, suddenly, with theatrical effect, a park-like sward of land lay before them leading to a sheet of blue water reflecting tall feather-palms and waving speargrass, all domed over with blue, and burning in the bright, bright sunshine.

“The Silent Pools!” cried Adams. “The very place where I saw the leopard chasing the antelope! Great Scott!—Hi! hi! hi! you there!—where are you going?”

The collector had raced down to the water’s edge; he knew the dangers of the place, for he divided the grass, filled his calabash with water, and dashed back before anything could seize him. Then, without drinking, he came running with the calabash to the white men.

Adams handed the calabash first to his companion.

Berselius drank and then wiped his forehead; he seemed disturbed in his mind and had a dazed look.
