They starred. It was the same peculiar sound they had heard before, and seemed to come from an immense distance. A pheasant crowed as he heard it in the jungle close by them, and a second farther away.

“What can it be?” whispered Mark. “Is there anything here?”—glancing around.

“There may be some genii,” said Bevis quietly. “Very likely there are some genii: they are everywhere. But I do not know what that was. Listen!”

They listened: the wood was still; so still, they could hear a moth or a chafer entangled in the leaves of the oak overhead, and trying to get out. Looking up there, the sky was blue and clear, and the sunlight fell brightly on the open space by the streamlet. There was nothing but the hum. The long, long summer days seem gradually to dispose the mind to expect something unusual. Out of such an expanse of light, when the earth is tangibly in the midst of a vast illumined space, what may not come?—perhaps something more than is common to the senses. The mind opens with the enlarging day.

It is said the sandhills of the desert under the noonday sun emit strange sounds; that the rocky valleys are vocal; the primeval forest speaks in its depths; hollow ocean sends a muttering to the becalmed vessel; and up in the mountains the bound words are set loose. Of old times the huntsmen in our own woods met the noonday spirit under the leafy canopy.

Bevis and Mark listened, but heard nothing, except the entangled chafer, the midsummer hum, and, presently, Pan snuffling, as he buried his nostrils in his hair to bite a flea. They laughed at him, for his eyes were staring, and his flexible nostrils turned up as if his face was not alive but stuffed. The boom did not come again, so they finished their dinner.

“I feel jolly lazy,” said Mark. “You ought to put the things down on the map.”

“So I did,” said Bevis, and he got out his brown paper, and Mark held it while he worked. He drew Fir-Tree Gulf and the Nile.

“Write that there is a deep hole there,” said Mark, “and awful crocodiles: that’s it. Now Africa—you want a very long stroke there; write reeds and bamboos.”

“No, not bamboos, papyrus,” said Bevis. “Bamboos grow in India, where we are now. There’s some,” pointing to a tall wild parsnip, or “gix,” on the verge of the streamlet.
