Jock Hastie - Apr54.   I guess that when this picture was taken we were over-staffed.   Our signals complement had a number of morse wireless operators who worked from an office in station headquarters.   There was normally no wireless operating to do and I think they spent most of their working time being teleprinter operators.   I think that Wilbur felt he had to find them something to do and had discovered a few tons of rock so that they could build a low wall around our transmitting station.   (Thanks to Dick Endecott)
