"Well, keelhaul me!" growled Dick. "He might just as well tell everybody what we've done as to examine the letter like that. There must be a screw loose in his head! Why, I never saw him act like that before. I can't smoke his roll any way you put it."

"I vas all mixed oop aboudt it meinseluf," said Carl, in a puzzled tone. "He iss acting so keveer as I can't tell. Oof he vas keeping drack oof somepody, vy don'd——"

Just then something happened that caused Carl to catch his breath. A startled exclamation escaped Dick.

In a flash the cotton bale had leaped into flame!

Wild shouts came from everywhere on that part of the levee. Stevedores dropped their burdens, bystanders lost their passive demeanor and teamsters jumped from their trucks. Buckets were secured and dipped in the river, and hustled toward the blazing bale with the water.

Meanwhile, Matt had slouched off to a good distance from the fire. While the boys drew nearer and watched excitedly, they saw an officer rush up to their chum, seize the cigarette from his lips and dash it on the planks and crush it under his foot.

"Can't you read, you idiot?" fumed the officer. "Look there!"

With his club he pointed to a sign which read, "No smoking." All over the levee there were signs to that effect. No matter which way a fellow turned the curt order, "No smoking," stared him in the face.

"Aw, forget it!" said Matt, with a curt disregard for legal authority that came to Dick and Carl like a slap in the face. "You're a copper, all right, but you can't get gay with me."

This insolence astounded the officer. Likewise it served to arouse his temper.
