The Nooper Swans and the Brent Geese, and other mysterious families whom Robin did not know, were calling overhead continually, and there was a constant boom-boom-boom going on among the reed-beds. Robin was a trifle scary and nervous now; this ramble had had so many adventures in it. But still he was eaten up by curiosity, and he tried to explore the reed-bed where the boom-boom was. And he pushed his way between the roots of the bulrushes, and flew a little here and there, while the sunset gradually faded out of the sky, until he came to a most wonderful place.
