The Buenos Aires, a fine ship of five thousand or more tons, dropped rapidly down the river. She had few cabin passengers, and of these only three were on deck. The remainder were in their cabins putting their belongings to rights.

These three men were the elder Daniels, his loutish son and Duval. But they all wore smart new clothes, and Duval had shaved off his mustache. As for the two Daniels, it is an example of what clothes can do to say that they looked more like prosperous, rather countryfied commission dealers than rugged fishermen from Maine.

“Let’s have a look at them pearls again,” Daniels was saying, after he had given a cautious glance about him to make sure they were not observed.

Duval reached into his pocket and drew out a canvas bag. From it he poured out a number of black, lustrous objects, catching them in a cupped hand.

“Twenty of the beauties,” he exclaimed; “twenty black pearls—the rarest gems that come out of the ocean.”

“What are they worth again?” asked the elder Daniels, licking his lips anticipatively.

“Thirty thousand dollars at the least.”

“Jiminy! Hold me, some one!” sputtered Zeb.

“And that, counting the gold dust in the cabin, makes a fortune of close upon seventy-five thousand dollars we got out of that old hulk, don’t it?”
