"What is the good of this artillery racket? Think of all the years we have fired our guns, only to wake the echoes of Falcon's Nest and Rock Castle! Why waste these charges of powder?"

"That is you all over, Ernest!" Jack exclaimed. "If a cannon shot costs so much it must bring back so much, or else be silent!"

"You are wrong to talk like that," said M. Zermatt to his second son, "and I do not regard the cost as wasted. To fly a flag over Shark's Island cannot be sufficient, for it would not be seen from far out at sea, while our cannon shots can be heard a good two and a half miles. It would be foolish to neglect this chance of making our presence known to any ship passing by."

"In that case," said Frank, "we ought to fire every morning and every evening."

"Certainly; just as they do in the navy," Jack declared.

"In the navy there is no danger of running short of ammunition," remarked Ernest, who was by far the most obstinate of the four brothers.

"Make your mind easy, my boy; we are not nearly out of powder," M. Zermatt assured him. "Two cannon shots, twice a year, at the beginning and the end of winter, only cost a trifle. It is my opinion that we should not discontinue this custom."

"Papa is right," said Jack. "If the echoes of Falconhurst and Rock Castle object to being disturbed from their sleep, well and good! Ernest will make an apology to them in verse, and they will be delighted. Come along, Fritz!"

"We must go and let Mamma know first," said Frank.

"And Jenny too," Fritz added.
