"I would not wait here—not in here, Steve. I would watch outside. Look! Do you see these grains of corn?"
He picked up a handful of the kernels from a sample basket on the table.
"Yes. What about them, Dick?"
"I will keep watch. If he comes out, I will follow him and every three or four feet I will let a little of this corn drop, so that it will mark a trail for you to follow. Do you see the idea?"
"Yes, and that is magnificent, Dick! That is the best chance we shall ever have of catching him. It will be better for him to come out, for he will lead you away from the busier part of the city, perhaps, so that it will be easier for us to take him! I'm off! I think we have a chance to get the scoundrel this time, thanks to you!"
They slipped out together, leaving the two unconscious men.
"I think Hallo will come to before long," said Dick. "The other will take longer for he seemed to be more badly stunned, or else he's not as strong as Hallo. Will Mike leave him there, do you think?"
"Yes. Why not? He will be thinking of his own precious skin, you may be sure. Good luck, Dick! I'll be back just as soon as I can!"
"Yes—hurry! But I think we'll be all right."
Dick took his place in a dark doorway on the opposite side of the street and began his vigil. The seconds seemed to drag by endlessly, but Dick never took his eyes from the entrance of the warehouse. And at last—he had really been waiting less than ten minutes!—he was rewarded. Hallo came out holding his hand to his head, staggering a little as he walked. Dick gave him a start, and then crossed and followed. He dropped his corn as he went, and his hand was on the automatic pistol in his pocket, which somehow gave him a sense of security.
