“Well, see what the storm blew in!” the young man exclaimed. “I didn’t expect you girls to pop in on a night like this.”
“Salt, how soon will you be driving to Riverview?” Penny asked breathlessly.
“About twenty minutes. As soon as my relief shows up.”
“May we ride with you?”
“Why, sure.”
Penny called down from the catwalk to tell Old Henry he need not wait. With a friendly wave of his hand, the cabin owner drove away. The girls then followed Salt into the drafty tower room.
Curiously they gazed at their surroundings. In the center of the room stood a small coal stove. Above it a tacked sign admonished: “Keep this fire going!” There was a table, two chairs and a telephone. Also a round clock which indicated seven-forty.
Before Penny and Louise could explain why they had come, Salt held up a warning finger.
“Listen!” he exclaimed. “Wasn’t that a plane?”
He ran out on the catwalk, letting in an icy blast of wind. In a moment he came back, grinning sheepishly.
