CHAPTER IV
A SENSATIONAL DISCOVERY
When Will awoke he began preparations for breakfast before paying any attention whatever to his chums, whom he believed to be sleeping quietly on their cots. It was November, and quite chilly in the apartment, so his next efforts were directed to coaxing the electric coils into a cheery glow.
Presently George came tumbling out in his pajamas and sat down on a rickety chair to talk of the adventures in prospect.
"I wonder if the Labyrinth mine is so much of a labyrinth after all?" he asked. "It seems to me that we might find our way through it without danger of losing ourselves," he continued with a yawn.
"It's some labyrinth, I take it," Will replied.
"Well, we can make chalk marks on the walls as we move along," suggested George. "Besides," he added, "we can string an electric wire through the center gangway and turn on the lights."
"There are probably electric lights there now," answered Will.
"Then there's no danger of our becoming lost," George argued.
"I wish you'd go to the back of the room and tip over those two cots," grinned Will. "It's the hardest kind of work to get Tommy and Sandy to bed, but when you do get them in bed once, it's harder still to get them out of it. Just tip the cots over and roll 'em out on the floor."
