"By thirty hills I hurry down,
Or slip between the ridges.
By twenty thorps, a little town,
And half a hundred bridges.
Till last by Philip's Farm I flow
To join the brimming river,
For men may come and men may go,
But I go on forever . . ."

These lines, taken from Tennyson's poem "The Brook", most probably describe the River Lymn. This is the river that once powered Stockwith Mill and which eventually joins the sea as the Steeping River at Gibraltar Point. It is large enough to attract duck, mainly mallard and teal, and moorhens may also be spotted.
