"From what I've heard of you, you're a one-two-seven boy and all to the good. How'd you like to get your lunch hooks on that bag of sparks? You can pull it off, if you get busy, and the undersigned will help. All you need is nerve and ginger. I can furnish my share. You've got an air ship. Well, hit the clouds and fly to me. I'll put you wise. Meet me at Bayou Yamousa, wherever that is, and come in a hurry. I'm going there now and I've got the start of you by some hours. This is a hot starter, and no 'con.'

[CHAPTER VIII.]

A BULLET FROM BELOW.

The boys were stunned. Could it be possible that this was a "straight tip," and not a hoax?

The letter was written on a scrap of paper taken from a notebook; and the envelope in which it was inclosed had been used twice. The first time it had been addressed to "Hubert Bangs, General Delivery, New Orleans, La." The "Hubert Bangs" had been scratched off with a lead pencil and Motor Matt's name written in its place. The ragged end of the envelope had been folded over and secured with a pin.

"A drick!" muttered Carl. "Dot feller Pangs iss vone oof Jurgens' gang."

"Strike me lucky," put in Dick, "but that's the sizing I give it, Matt."

"You're wrong," averred Matt. "If a trick was intended, Bangs would never have used an old envelope bearing his name. Be sure of that. Even if a trick was intended, it would be a ruse to get us into the vicinity of the gang of thieves. The gang wouldn't do that, being too anxious, just now, to keep out of sight. But, supposing that was Jurgens' game, wouldn't it be a good thing for us to come close to the thieves? They have the diamonds, and they are what we want."

"Right-o!" exclaimed Dick. "Hoax or no, our move is to slant away for Bayou Yamousa, where we intended to go in the first place. We'll not find Yamousa there, but luck of another kind may be waiting for us."
