“That thing might have hit some of us,” cried Jefferson Arnold. “Better look out! There may be others.”

“I hardly think so,” was Nick Carter’s calm response. “That is a message only, unless I am much mistaken. Don’t you see there is something tied around the wooden shaft just below the head. Looks like a bit of cloth.”

He stepped forward, and, with a sharp tug, drew the spear from the hard earth. Then he unwound from it a silk necktie of a rather unusual pattern.

“It is Leslie’s!” shouted Jefferson Arnold wildly, as he held out his hand for the tie. “I never saw one like it except on my son. He had it on when we were in that city yonder.”

“I remember it,” answered Nick, looking at the curious combination of colors thoughtfully. “It struck me as unique, and yet in perfect taste. Still, probably there are others like it in the world.”

“Perhaps. But it isn’t likely others would have these initials embroidered on the back of it,” rejoined Jefferson. “See! ‘L.A.’ No, Carter, this is my boy’s necktie, and he is in the hands of those rapscallions over there.”

The father buried his face in his hands, and rocked to and fro convulsively.

“Well, even so, what is the meaning of the spear coming over the rocks like this?” asked Patsy.

“There can be only one meaning,” returned Nick Carter. “Calaman, the high priest of that strange city, Shangore, sends us this necktie to let us know he has Leslie Arnold a prisoner.”

“Why did we ever come away without making sure he was safe?” groaned Jefferson Arnold. “It was my fault. My boy will think we have deserted him.”
