“You are kind; suppose we say three reports in succession from one of the revolvers means that you are urgently wanted?”
“A good plan; if there is no wind the sound will carry well.”
“What signal will you use in calling us?”
“I do not think the necessity can ever arise.”
“But it may: who shall say?”
“I brought some sky rockets with other fireworks to amuse Ruth; three of those sent up will serve provided some one happens to be looking this way; otherwise I shall fire my rifle three times,—the same as you will do with your smaller weapon.”
“Then that is the understanding between us.”
CHAPTER XVII—An “Injin” Story
The doctor and his little daughter stood at the landing, the mother remaining at the house, and watched the canoe as it put out from the shore and headed toward the bungalow on the other side of the lake. The fact that the boys had to sit facing the other way did not prevent them from turning their heads several times and waving a hand or paddle in response to the good-bye greeting of Sunbeam. Mike having no paddling to do indulged in the exchange much more than his companions.
By and by the girl at the request of her father ran to the house and brought back his powerful telescope, which he pointed at the boat. Unaware of this, and carrying no binoculars, the lads did not know how distinctly they remained in the field of vision of their friends and naturally the signalling between the parties stopped.
