up his arms and fell back. A shriek
of terror went up from the Zwengi, while the pigmy arrows played havoc
among them as they fled back to their canoes. Next instant a canoe put
out from the south bank.

"Look there!" shouted Burt, peering through his glasses. "White helmets!
We're saved, Critch!"

"Yes," and Critch began to dance up and down, waving his arms like mad,
"an' it's your uncle and Cap'n Mac! Hurray! Hurray!"

A week later a small German Company steamer was making her way down the
broad Makua River. In the shade of her awning reclined Mr. Wallace,
Captain Montenay, Burt and Critch. John was busying himself forward, and
the decks of the little craft were littered with long, curved packages
that looked strangely like elephant tusks.

"Well, it was mighty lucky for us that you started after us that way,"
Burt was saying. "If you'd tried to strike right through the black dwarf
country we'd have missed you. Ain't it queer how things worked out?"

"Not a bit," asserted Captain Mac quietly. "It looks to me, Burt, as if
the hand o' Providence was in it."

The boys stared at the Scotchman for a moment in wonder. Suddenly Burt

taken from the mummy as he and Critch had unwrapped it. Mr. Wallace took
it with an exclamation of pleasure.

"This is really something worth having, boys!" he declared, carefully
unfolding the papyrus. "Hello! Let's see what it says."

In spite of its age, the first part that unrolled showed clear and
strong picture writing, in bright colors. The others gave a simultaneous
exclamation, while Mr. Wallace bent his brows in the endeavor to read
it.

"Well, it's nothing special," he announced, "merely being scenes from
the life of Ta-En-User, with the story of his achievements. I think we'd
better roll it up and keep it from the damp now; we can read it later.
It'll make something great for your room, Burt! It's mighty few boys
that can boast of having a relic like that hanging on their walls!"

"Well, I'm kind o' sorry we're going home," sighed Critch. "Won't this
be a great yarn to write up for the school paper, eh, Burt?"

"Nonsense!" said Mr. Wallace sharply. "It's too big a story for that,
Critch. Why don't you two chaps get busy and make a book out of it? I'll
help you in the stiff places."

"Hurray!" cried Burt.

"Bul
