s than half-an-hour's search had placed them in
possession of three more bags similar to the first, but two of which
contained stones far more valuable, than even the first; one nothing but
diamonds, and fine ones at that. These, after investigation, were
placed aside, and operations resumed.

But further excavation all round and under, brought nothing to light.

"That'll be the lot, I'm thinking," said Fleetwood. "It about
corresponds with what Hlabulana said they'd got."

"Joe," said Wyvern gravely. "Do me the favour to pinch my leg, and
pinch it hard, just to show that I'm not dreaming, you know. The whole
thing seems too good. Seems as if one would wake up in a minute."

"It does, doesn't it," answered the other, equally serious. And again
they lapsed into silence, each full of his own thoughts.

"Now for what's to be done," went on Fleetwood. "I don't like these
diamonds. There I'm in my element, for, as you know, I was a digger in
the early Dutoitspan days--not that they ain't devilish good ones. But
they're awkward things to hawk around anywhere in South Africa--the
I.D.B. law, you know. Suppose by any chance it got round that one had a
bag of diamonds like that in one's possession, they'd have one watched
day and night to find out how one got hold of it. Then it'd be bound to
give away the rest of the show. We don't want that."

"Not much. Look here, Joe. I've an idea which may be a good one or may
not. We can't possibly carry away that box. Let's bury it again and
call for it some time later when things are quiet again. As for the
diamonds, we'll plant them in some other place just to make sure that
Hlabulana doesn't show them to someone else, and pick them up at the
same time as the bar gold. How does it pan out?"

"First rate. Only, old chap, I don't think it'll be much a case of _us_
calling for them. I'm pretty sure I shall have to undertake it for
both, for with a recollection of the portrait in your room in Ulundi
Square you'll be in no hurry to repeat this expedition."

They set to work to bury the box again. It mattered little enough if
here were marks of fresh digging, for who in the world would ever dream
of treasure lying buried in this particular cave--one among many--
without some due? Hardly had they done so than the entrance darkened,
and Hlabulana stood within. In the excitement of their discovery they
had forgotten his very existence. Quickly Fleetwood explained t
