At Varna it became necessary for Helmar to change some of his money into Turkish currency.

"I want you to get this money changed, Mark," said he, when they alighted from the train; "you are better able to do it than I, I do not understand the ways of these money bureaux. There is sure to be one somewhere handy. While you do this, Charlie and I will seek an hotel, and then return here and await you."

He handed Arden some notes as he spoke, carefully counting them out to him lest he should make a mistake.

"The exchequer is getting low," he went on, as he saw his companion pocket them; "that is half of my all, and is just sufficient to see us all three to Constantinople."

"Is it as bad as that?" said Mark, looking keenly at Helmar as he spoke. "It's not a very lively look-out for us. Well, I'll meet you here in a couple of hours' time. I dare say by that time I shall have succeeded in changing them, and you in finding a suitable hotel." And he turned to go.

"Yes, we'll be here in the ticket-office when you return," Helmar called out after him; "don't be longer than you can help."

As soon as he had gone, Charlie Osterberg and Helmar left in search of quarters.

"This is the queerest place I was ever in, Helmar," said Charlie, as they turned into a narrow, unevenly-paved street. "These buildings all look as if they were about to collapse—and don't they look dirty!"

"Eh? What was that you were saying?" replied his companion. "Oh, yes—the houses—'m, I dare say they aren't over-clean. I say, Charlie, I'm half sorry I sent Arden with that money, somehow I wish I'd gone myself."

"Why, what do you mean? He'll change it right enough."
