Japanese Print

Both skyed
In south-west wind beyond
Poplar and fir tree, swallow,
Heron, almost collide,
Swerve
With a rapid
Dip of wing, flap
Each in an opposite curve,
Fork-tail, long neck outstretched
And feet. All happened
Above my head. The pair
Was disappearing. Say I
Had seen, half hint, a sketch on
Rice-coloured air,
Sharako, Hokusai!
