ent. The Turks scattered and waited, but there was no explosion.
With a smile the Turkish officer picked up the tin. Unfastening a note
tied round it, he read:

"DEAR YUSSEF,--This is the _real_ stuff. By the way, you were at Rugby
with me. Shall be sorry to kill you.--Yours, etc.,

"CLAUD DUFAIR."

Plunk! came a stone into the Australian lines; round it was fixed a
note:

"DEAR CLAUD,--Many thanks--it was a god-send. Fancy you being here. I
thought you would have been guarding the Marys and Mauds of London from
the Zepps. Congrats! Of course, I shall be sorry to kill
_you_.--Yours, etc.,

"YUSSEF BEY.

"_P.S._--There will be no firing to-day--go to bed."

And there was no firing. This Turkish officer, like every other
Turkish soldier, was a gentleman.

It is remarkable how circumstances produce the inventor. At Hell-Fire
Post the men found that the ordinary square periscope was almost
useless. Every time one went up, bang went a Turk's rifle, and the
periscope was blown to smithereens. Indeed, The Kangaroos lost nearly
all their periscopes in the first few days. Now this was awkward.
Periscopes are life-savers, for the periscope prevents a man pushing
his head above the parapet to see if Johnny Turk is coming over to say
"Good morning." Something had to be done, so the famous quartette
began to cudgel their brains.

"I've got it," said Claud, picking up a walking-stick.

"Got what," inquired Bill.

"An idea--you watch." Taking a penknife out of his pocket, he deftly
and quickly cut away the inner portion of the stick. This kept him
busy for a couple of hours. When finished, he took a little pocket
mirror out of his haversack.

"Too big," said Bill.

"No, it isn't," answered Claud, slipping a diamond ring off his finger.
He scratched the mirror, then cut two pieces out of it. These he fixed
into the walking-stick. "There you are now--a brand new periscope."
And it proved just the thing. The field of vision was quite good.
Being small it did not attract attention. The result of this discovery
was that every officer's stick was immediately commandeered, and with
the aid of Claud's ring and other people's mirrors, a good supply of
periscopes were made.

"You think you're smart fellers, I suppose," said Bill, his envy roused
by this success. "But I'll show you fellers something in a day or
two."

"What is it?"

"'Wait and see,' as old Asquith says." For the next few day
