These little incursions into the enemy's territory Captain Harrison conducted with consummate boldness and skill, and with a considerable measure of success, for it was quite a favourite amusement of his to devise and suggest schemes of a particularly alluring character which, when adopted by the enemy, he of course triumphantly circumvented without difficulty.  There was only one fault to find with this propensity on the part of our skipper, but in my humble judgment it constituted a serious one.  It was this.  Captain Harrison's personality was a distinctly striking one; he was the kind of man who, once seen, is not easily forgotten; and I greatly dreaded that some day, sooner or later, the reckless frequenter of the low-class Freetown taverns would be identified as one and the same with the captain of H.M.S.  _Psyche_, who was of course frequently to be seen about the streets in the uniform of a British naval captain.  Indeed I once took the liberty of delicately hinting at this possibility; but the skipper laughed at the idea; he had, it appeared, the most implicit faith in his disguises, which included, amongst other things, a huge false moustache of most ferocious appearance, and an enormous pair of gold earrings.
