Here it is--_re_--that's to say, about black soldiers.

I have it on my notes that they are from the 10th Soudanese battalion of the Egyptian army.

They are recruited from the Dinkas and the Shilluks--two negroid tribes living to the south of the Dervish country, near the Equator." "How can the recruits come through the Dervishes, then ?" asked Headingly sharply.
"I dare say there is no such very great difficulty over that," said Monsieur Fardet, with a wink at the American.
"The older men are the remains of the old black battalions.

Some of them served with Gordon at Khartoum, and have his medal to show.
The others are many of them deserters from the Mahdi's army," said the Colonel.
"Well, so long as they are not wanted, they look right elegant in those blue jackets," Miss Adams observed.

"But if there was any trouble, I guess we would wish they were less ornamental and a bit whiter." "I am not so sure of that, Miss Adams," said the Colonel.
