The day before we had seen a good battle in the clouds when the Boche plane had crashed, and a Transvaal machine-gun officer brought the report that the British airman had been Pienaar.

'Well done, the old _takhaar_!' he cried, and started to yarn about Peter's methods.

It appeared that Peter had a theory that every man has a blind spot, and that he knew just how to find that blind spot in the world of air.

The best cover, he maintained, was not in cloud or a wisp of fog, but in the unseeing patch in the eye of your enemy.

I recognized that talk for the real thing.
