"You are right; words are cheap," said Jack; "but for want of something trustier I must ask you to give yours that you knew nothing of that crocodile. If you cannot give me an assurance on this point I shall do as I threaten. I know you are three to two, but we need not fear a set of cowards who shoot at helpless persons from an ambush."

James Strong flushed and glanced at his companions, who reddened also. Nevertheless, he maintained a bold front, and replied readily enough—

"We have not come into the interior of Africa to guess riddles. I know nothing about any crocodiles; but if one had eaten your friend there as he crossed the ford we should not have gone into mourning. It might have had you too, without many tears from us. As to shooting from an ambush, you may explain what you mean if you please, or do the other thing if you prefer it. There's no law against riddles and lunatics that I know of, in these parts."

"Very well, then; so be it," said Jack. "At the same time let me tell you this: Prevaricate as you will, we know well enough what we know; you shot at us from the cliffs at Graciosa—good. Luckily you are very bad shots, all of you. Now I am a dead shot. I have twice been in the Queen's Hundred at Wimbledon and Bisley, and my friend here is not far behind me at a mark. What you are to understand is this—that if any of you fellows at any time fire at us, either of us, and miss, we shall shoot back, and we shall not miss; if we can't get a shot at you at once (for you are likely to be behind an ambush), we shall let fly at our next meeting. Bear this in mind for your good."

"Come, chuck the sermon," said James Strong, who was the spokesman of the party, and a very rude one at that.

"Very well," said Jack, "words are thrown away upon fools; next time I shall shoot."

And with this crude repartee we left these worthies and crossed the ford, and gained a good ten miles upon them by nightfall.

Now that my tale is taking us rapidly towards the spot in which, according to our maps, old Clutterbuck's treasure lay buried, it would be as well to present for the reader's assistance a copy of the map and instructions as we each received them from Steggins the lawyer on the day of the reading of the will.

Here is the copy, which I present to the reader with apologies for its shortcomings as an artistic production. I could have made it more presentable and accurate, but it is better to reproduce it as I received it.
