“None—at present.”

Warden himself was surprised when his lips framed the qualification. For no assignable cause his mind traveled to the lowering face on the gourd, then reposing in his portmanteau at Waterloo Station, and he remembered the curled scrap of tattooed skin in his pocket. He had not mentioned the calabash to the official. Though it bore curiously on the visit of the men of Oku to the Isle of Wight, he believed that such a far–fetched incident would weaken his statements. Since he was inclined at first to err so greatly in his estimate of the Under Secretary’s knowledge of West African politics, he was now more resolved than ever not to bring an extravagant toy into a serious discussion. Any reference to it would be ludicrously out of place. He was beginning to entertain a deep and abiding respect for the Foreign Office and its denizens.

The Under Secretary asked a few additional questions before he rose to fold up the map. Warden took the hint, and was about to depart when he received an unlooked–for piece of news.

“By the way, it is almost a certainty that Count von Rippenbach accompanied the Emperor in the visit paid to the Sans Souci?” said the official.

“I assume his identity solely from paragraphs in the newspapers.”

“It will interest you to learn that the Count has just returned from an exploring and hunting trip in the Tuburi region.”

Now, Tuburi lies in the no–man’s land that separates Lake Tchad from German West Africa, and Warden met the Under Secretary’s bored glance a second time with quick comprehension.

“I think,” went on the quiet voice, “I think it would be well if you kept the Colonial Office posted as to your movements during the remainder of your furlough. Personally, I expect no immediate developments. The Emperor is a busy man. He can only devote half an hour each year to affairs that affect the Niger. But, keep in touch. You may be wanted. I am exceedingly obliged to you. One learns so much from the men who have passed their active lives in lands which one has never seen except in dreams. I dream here sometimes, in front of that map—and its companions. Oh, I had almost forgotten. Do you know Mr. Baumgartner?”

“Only by sight.”

“That is useful. It might help if you were to meet him in some unexpected locality. And his yacht, the Sans Souci, you have noted her main features, such as the exact number of windows in her deck houses, or the cabin ports fore and aft of the bridge?”
