"Yes, I know," answered Harry. "That's why I'm trying to be extra careful. I'm just as anxious for a light as you are."

"The rats are coming closer," observed Jack, a slight quaver perceptible in his voice. "I don't want them to start anything."

"All right now, Harry; lean on me a bit to balance yourself," urged Ned. "Make sure this time, and get it in your cupped hands."

"Here goes!" announced Harry, lifting one foot and striking the match upon the sole of his shoe. "Here comes the light!"

But, contrary to expectations, the light did not come, although the lad tried again and again.

"Try the other match, Harry; maybe this one got wet somehow and won't work," suggested Jack, stepping closer.

"I have tried them both," declared Harry in a faint voice.

"What's the matter, then?" demanded Jack excitedly.

"I guess they are those safety matches that will light only on the box," was Harry's explanation. "I haven't the box, either," he added in a voice scarcely above a whisper. "It's no go, boys!"

"Look through all your pockets," directed Ned, "and see if there isn't a scrap of box left by oversight. We must have a light!"
