"And how does it operate?" queried one.

"It is one of those ingenious Yankee contrivances. I have never seen one quite like it, but my intelligence makes its principle plain. Evidently one inserts the tube into the dynamite, so, and presses the bulb—-"

There came a loud cry from General Antuna, who had bent closer; he clapped his hands to his face and staggered from his chair, for in suiting his action to his words the colonel had squeezed the bulb, with the result that a spray of salt water had squirted fairly into his superior officer's interested and attentive countenance.

"My eyes! Dios mio! I am blinded for life!" shouted the unhappy general, and his subordinates looked on, frozen with consternation.

The author of this calamity blanched; he was stricken dumb with horror.

Some one cried: "A doctor, quickly. Jesus Cristo! Such carelessness!"

"This is terrible!" another stammered. "It will explode next."

There was a concerted scramble away from the table.

Leslie Branch laughed—it was the first time that O'Reilly had ever heard him give audible evidence of amusement. His reedy frame was shaken as by a painful spasm; his colorless face was distorted, and from his lips issued queer, hysterical barks and chortles. "Tell 'em it's nothing but brine," he said, chokingly.

When this welcome intelligence had been translated, and when the general had proved it to be true, there was a great sigh of relief, followed by a subdued titter at the colonel's expense. The latter was chagrined. Having made himself and the comandante ridiculous, he took refuge behind an assumption of somber and offended dignity. But it was plain that he still considered these Americans dangerous people, and that his suspicions were as keen as ever.
