"Be careful, Ivanovich," he urged. "It is not possible for you to go forth in the clothes you wear. There is danger lurking abroad for the high born."

Ivan shrugged his fearless shoulders. "They would not dare to harm me," he answered.

"He's right. Those clothes won't do," said Warren decidedly. "We don't know where we are going, nor whom we may meet. Where can we find something rough for you to wear?"

"Down below are the workmen's extra blouses," said the soldier. "When I worked here, the room was kept locked, but you might perhaps force the door. There are blouses and rough shoes there. But I tremble; I tremble!" He suddenly lapsed into Polish. "Let these Americans go, Prince," he begged. "Harm never come to them. They go always as though they wore a charm. Poland shall yet rise, my Prince. From these ashes she shall arise more beautiful than ever. She will need you then."

Ivan listened with flashing eyes. "I shall be here," he said simply. "I shall be here, I shall answer when she calls, but in the meantime shall it be said that in Poland, even in her darkest hour, children were stolen for such evil purposes? Never, never!" He turned to Warren. "For a year now," he said, "we have been organizing these Boy Scouts that you have so many of in America. Let us pass the word to them. If little Elinor and the stranger are to be found, surely they will find them. My rank has always hampered me, but even then I know that boys will go where no others can penetrate. What do you think?"

"It's the dandiest idea I ever heard!" exclaimed Warren, his face lighting. "We will have to depend on passing the word to them as we find them here and there, but it's the only thing to do, so let's go to it."

"First the workman's clothes," said Ivan.

"Assuredly!" exclaimed the Professor. "Let us disguise ourselves and go forth. I know that we will find the dear children playing near the corner."

"Father, you must stay here," said Warren, determination in his voice.

"Of course not; of course not!" said the Professor. "Do you expect me to sit idly here while my youngest child needs my protection?"
