This is The Shore Road by Norman MacCaig - just noticed the poem about the Border Collie. He's a good writer for the out doors.
The Shore Road by Norman MacCaig
The sea pursued
Its beastlike amours, rolling in its sweat
And beautiful under the moon; and a leaf was
A lively architecture in the light.
The space between
Was full, to splitting point, of presences
So oilily adjustable a walking man
Pushed through and trailed behind no turbulence.
The walking man
With octaves in his guts was quartertone
In octaves of octaves that climbed up and down
Beyond his hearing, to back parts of the moon.
As though things were
Perpetual chronologies of themselves,
He sounded his small history, to make complete
The interval of leaves and rutting waves.
Or so he thought,
And heard his hard shoes scrunching in the grit,
Smelt salt and iodine in the wind and knew
The door was near, the supper, the small lamplight.
