Sea fever
by john masefield

i must down to the seas again, to the lonely sea and the sky,
and all i ask is a tall ship and a star to steer her by,
and the wheel's kick and the wind's song and the white sail's shaking,
and a grey mist on the sea's face and a grey dawn breaking.

i must down to the seas again, for the call of the running tide
is a wild call and a clear call that may not be denied;
and all i ask is a windy day with the white clouds flying,
and the flung spray and the blown spume, and the sea-gulls crying.

i must down to the seas again to the vagrant gypsy life.
to the gull's way and the whale's way where the wind's like a whetted knife;
and all i ask is a merry yarn from a laughing fellow-rover,
and quiet sleep and a sweet dream when the long trick's over.
