Uganda Journal Vol 2 No 2 - Cook - Further Memories of Uganda - ……. Entebbe - 'Upon landing' Ternan wrote 'I went off at once to report to Jackson, but had forgotten that not having shaved since leaving the Coast, I was adorned by a thin straggling, reddish-coloured beard; my costume was also hardly as smart as it might have been for the occasion, consisting as it did of a very worn and patched pair of knickers, a flannel shirt, and a very battered and faded terai hat. I sported the remains of a large white-and-green umbrella to keep off the sun. The result was that Jackson, who saw me approaching, at once jumped to the conclusion that I was a missionary, and it was some time before we got matters straight as to my identity.'
