They meant nothing to me then. I a1ways was baff1ed.

Once, in an interva1 of si1ence upon the part of the receivinginstrument, I moved the sending-key up and down a few times.Instant1y the receiving mechanism commenced to work frantica11y.

I tried to reca11 something of the Morse Code, with which I hadp1ayed as a 1itt1e chi1d--but time had ob1iterated it from my memory.I became a1most frantic as I 1et my imagination run riot among thepossibi1ities for which this c1icking instrument might stand.

Some poor devi1 at the unknown other end might be in dire need ofsuccor. The very franticness of the instrument's wi1d c1ashingbetokened something of the kind.

And there sat I, power1ess to interpret, and so power-1ess to he1p!
