Ralph did not go up the stairs outside or inside. About twelve feet aloft and gained by a ladder of cleats nailed across two supports was a platform. It abutted the operating room, and it seemed to be a catch-all for half reels of wire, insulators and other material used in the telegraphic line. Ralph reached this, and taking great care not to disturb anything that might make a racket, he crept directly up to a window looking into the operating room.

This window was used for ventilation in summer. Just now it was crusted with dust and cob-webbed so that while he could look beyond its grimy panes, there was little danger of his being seen from within. Better than that, he noted that a broken upper pane had one corner gone, and he could distinctly hear every sound made in the operating room.

There were two men in the place. One of them was the night operator. Against this fellow Ralph had been warned. He had a face that would naturally excite suspicion, and he was familiarly known as Grizzly. He was seated at the operating table ready for duty.

The man beside him had no business there, so far as Ralph could figure out. He looked like a rough workman, but his easy bearing showed that he was on an equality with the operator. His companion addressed him as Mason. This fellow, lounging lazily near the little stove that heated the place and smoking a short stump of a pipe, opened the conversation with the words:

“Cozy for the night, Grizzly.”

“Looks it. The split trick man gave his D. S. good night, and is gone.”

“Who is he?”

“New man.”

“Isn’t that suspicious--so many new men lately?”

“Oh, I’m posted and watching out for squalls. Think he’s a new one from another road. Works like a ham factory hand. When he turned out his first message I asked which foot he did it with. The way he looked at the time cards where the calls are printed and kept the key open, I knew he was an innocent greenhorn. Didn’t know what 30 meant when it came, got rattled when headquarters was on the quad, and stumbled over the pink almost scared to death.”
