"Green ones?" asked Bones anxiously.

"Lord, of every colour," said Bosambo, "blue or green or red, even golden crocodiles have I in my splendid river. But they will cost great money because they are very cunning, and my hunters of crocodiles are independent men who do not care to work."

Bones dried up the flood of eloquence quickly.

"O Bosambo," said he, "there is no money for this palaver, but a green crocodile I must have because the evil people of the Lower Isisi say I have put a spell on their land because I slew the Green One, M'zooba, also this crocodile must I have before the moon is due. My Lord M'ilitani has sent me many powerful messages to this effect."

This was another matter, and Bosambo looked dubious.

"Lord," said he, "what manner of green was this crocodile, for I never saw it?"

Bones looked round.

Neither the green of the trees he saw, nor the green of the grass underfoot, nor the green of the elephant grass growing strongly on the river's edge, nor the tender green of the high trees above, nor the tender green of the young Isisi palms; and yet the exact shade of green it was necessary to secure. He ransacked all his books, turned over all his possessions and Hamilton's too, in an endeavour to match the crocodile. There was a suit of pyjamas of Hamilton's which had a stripe very near, but not quite.

"O Ahmet," said Bones at last in desperation, "go to the storeman, and let him bring all the paints he has so that I may show Bosambo a certain colour."
