"I must see this craft's master, and at once," Darrin insisted.

"He here cannot be at dis minute," replied the foreign mate. "To de cabin mit me come, please."

"Your cargo is wood pulp, you say?" Dave continued.

"Yes, sir."

"Where is it?"

"In our hold, already, sir," answered the mate.

"Throw off that hatch," Dave directed, pointing. "I am going to inspect your cargo."

The hatch was promptly uncovered. Leaving Burton and his men on deck, Dave descended into the hold by a ladder, followed by the mate and two of the "Olga's" seamen. A brief inspection proved that the hold was well filled with a cargo of wood pulp.

"Now, you vill go to de after hold, please?" asked the mate, as Darrin climbed up to the deck.

"Yes," Dave nodded, and went aft, followed by four of his men, while Burton and the others remained forward. Here in the after hold the same kind of cargo was found. The "Olga" looked like a straight enough craft, but there was something in the manner of the mate that made Darrin suspicious.
