XXXIII. Harbour Whistles
Over old roofs and past decaying spires
The harbour whistles chant all through the night;
Throats from strange ports, and beaches far and white,
And fabulous oceans, ranged in motley choirs.
Each to the other alien and unknown,
Yet all, by some obscurely-focussed force
From brooding gulfs beyond the Zodiac’s course,
Fused into one mysterious cosmic drone.
Through shadowy dreams they send a marching line
Of still more shadowy shapes and hints and views;
Echoes from outer voids, and subtle clues
To things which they themselves cannot define.
And always in that chorus, faintly blent,
We catch some notes no earth-ship ever sent.
