"Say," remarked Ben, pausing in his task of emptying a squat chest, marked, Don Ramon De Guzman, Sevilla, "you don't think I'm going to touch any of this loot do you? It all belongs to you boys and Bluewater Bill, and I've no right to a cent's worth of it. The excitement is enough for old Ben Stubbs."

"Well, you've got a nerve!" cried Frank, "to think that you are not going to get a share. Why we are all in on this, and, when we have all the stuff out and get it valued, we'll divide it up in fair proportion."

"You won't get me to take any of it," grumbled old Ben obstinately, grubbing away in the treasure-filled box.

"We shall see about that," said Frank, who knew it was useless to argue with the old sailor.

As they worked feverishly, from time to time gazing at the sky in apprehension of the appearance of Luther Barr's dirigible, the adventurers had an illustration of the manner in which the old Spaniards guarded their treasure that came very near having a tragical termination.

Ben Stubbs had hammered off the lock of a huge chest, with a semi-circular top, and was in the act of flinging back the lid, when he stopped short with an exclamation. It was fortunate for him that he paused, for as he did so, the lid, actuated by some hidden mechanism, swung back and a steel arm, tipped with sharp prongs, shot out. Had the sailor been less nimble the device would undoubtedly have caved his skull in. As it was, it missed him only by an inch.

"Well, that's a nice murderous contrivance," gasped the astonished sailor.

An examination showed the boys that the tips of the prongs were stained and they had little doubt, as they examined it, that the marks were those of human blood. The life fluid of some old-time marauder who had paid with his life for his attempt to rifle the chest. The death-bearing arm, they discovered, was actuated by levers and springs, connecting with the lifting mechanism of the lid. The boys were compelled to admit, as they examined the device, that fiendish as it was it had been designed by a master mechanic of his time.

As they worked, you may imagine, the boys swept the sky for a sign of Luther Barr's dirigible, but not a trace of her did they discover that day.

"It begins to look as if we had beaten Luther Barr this time," cried
Harry, exultingly.
