The evening attire which he now resumed was wholly white,—from his pith helmet down to his canvas shoes, he was in white, with the exception of his tie, which was black. He looked at himself in a glass when at the point of leaving his house, and he felt satisfied with his appearance; only he should have dearly liked to exchange his black tie for one of scarlet. He could not understand how it was that he had never passed a draper’s window in London without staring with envious eyes at the crimson scarves displayed for sale. No one could know what heroic sacrifices he made in rejecting all such allurements. No one could know what he suffered while crushing down that uncivilised longing for a brilliant colour.

Just before leaving the house he went to his desk and brought out of one of the drawers a small ivory box. He unlocked it and stood for some time with his face down to the thing that the box contained—a curiously-speckled stone, somewhat resembling a human ear. While keeping his head down to this thing his lips were moving. He was clearly murmuring some phrases in a strange language into that curiously shaped stone.

Relocking the ivory box, he returned it to the drawer, which he also locked. Then he left his house, and took a path leading to a well-built villa standing in front of a banana-jungle, with a tall flag-pole before its hall door—a flag-pole from which the union-jack fluttered, indicating to all casual visitors that this was the official residence of her Majesty’s Commissioner to the Gambia, Commander Hope, R.N.

“Hallo, Koomadhi!” came a voice from the open window to the right of the door. “Pardon me for five minutes. I’m engaged at my correspondence to go to England by the Penguin this evening. But don’t mind me. Go through to the drawing-room and my daughter will give you a cup of tea.”

“All right, sir,” said Dr Koomadhi. “Don’t hurry on my account. I was merely calling to mention that I had forwarded my report early in the day; but I’ll wait inside.”

“All right,” came the voice from the window. “I’m at the last folios.”

Dr Koomadhi was in the act of entering the porch when his pith helmet was snatched off by some unseen hand, and a curious shriek sounded on the balcony above the porch.

“The ruffian!” said Koomadhi, with a laugh. “The ruffian! He’s at his tricks again.”

He took a few steps back and looked up to the balcony. There sat an immense tame baboon, wearing the helmet and screeching with merriment.

“I’ll have to give you another lesson, my gentleman,” said the doctor, shaking his finger at the creature. “Hand me down that helmet at once.”
