That day they intended to discover the North Cape like 'Othere, the old
sea-captain', in the book of verses which Una had brought with her; but
on account of the heat they changed it to a voyage up the Amazon and the
sources of the Nile. Even on the shaded water the air was hot and heavy
with drowsy scents, while outside, through breaks in the trees, the
sunshine burned the pasture like fire. The kingfisher was asleep on his
watching-branch, and the blackbirds scarcely took the trouble to dive
into the next bush. Dragonflies wheeling and clashing were the only
things at work, except the moorhens and a big Red Admiral, who flapped
down out of the sunshine for a drink.

When they reached Otter Pool the _Golden Hind_ grounded comfortably on a
shallow, and they lay beneath a roof of close green, watching the water
trickle over the flood-gates down the mossy brick chute from the
mill-stream to the brook. A big trout--the children knew him
well--rolled head and shoulders at some fly that sailed round the bend,
while, once in just so often, the brook rose a fraction of an inch
against all the wet pebbles, and they watched the slow draw and shiver
of a breath of air through the tree-tops. Then the little voices of the
slipping water began again.

'It's like the shadows talking, isn't it?' said Una. She had given up
trying to read. Dan lay over the bows, trailing his hands in the
current. They heard feet on the gravel-bar that runs half across the
pool and saw Sir Richard Dalyngridge standing over them.

'Was yours a dangerous voyage?' he asked, smiling.

'She bumped a lot, sir,' said Dan. 'There's hardly any water this
summer.'
