“They seem to is right,” agreed more cautious Bob. “But remember we’ve tried them for only a comparatively few feet. How they will work at a long distance is another question.”

“Of course that’s so,” agreed Jack thoughtfully, “but, for the life of me, I can’t see why they won’t catch them just as well at a long distance as at a short. Anyhow we’ll know before long. I’ll take my bike and go up to the lake first thing in the morning and we’ll give them another try.”

“That’s the ticket, and now I move we hit the hay for a few hours’ sleep, I’m about played out working all day and most of the night the way we’ve been doing lately,” Bob said as he switched off the light.

The two boys had indeed as Jack put it, “been burning the candle at both ends,” and they no more than touched their pillows before they were sound asleep. Nor did they awake until their sister, Edna, called them.

“Come on there, you sleepy heads. Think I’m going to keep breakfast waiting for you all day?” she cried as she sprinkled a few drops of water on Jack’s face.

“Who called out the fire department?” the latter muttered as he sat up and rubbed his eyes.

“It needs more than a fire department to get your eyes open,” Edna laughed as she gave Bob a similar treatment. “You’ve got just three minutes to get down to the table or you get nothing to eat,” and with the ominous threat she ran from the room.

“Guess she means it,” Bob yawned as he threw the bed clothes to one side.

They made it with ten seconds to spare, but, as Jack declared, “a miss is as good as a mile.”

“Thought I’d scare you into hustling,” Edna declared as she placed a huge plate of hot cakes in front of them.
