If they only had more battery—could make the current in the wire stronger! Immediately on the thought came remembrance of the emergency battery he had made the previous year at Watson Siding. He spun about toward the office water-cooler. But only to utter an exclamation of disappointment. This cooler was of tin—of course useless for such a purpose.

Hurriedly he began casting about for a substitute. “Billy, think of something we can make a big battery jar of!” he cried. “To strengthen the wire!”

“A battery? But what would we do for bluestone? I used the last yesterday!”

Alex returned to the table, and threw himself hopelessly into the chair.

At the moment the Jakes Creek operator answered his call, and received the message of warning.

“Say,” said Saunders, “perhaps some of the other fellows on the wire have bluestone and the other stuff, and could make a battery!”

Alex uttered a shout. “That’s it!” he cried, and springing to the telegraph key, as soon as the wire closed, called Indian Canyon. “Have you any extra battery material there?” he sent quickly.

“No. Why—”

Abruptly Alex cut him off and called Imken. He also responded in the negative. But from Terryville came a prompt “Yes. Why—”

“Have you one of those big stoneware water-coolers there?”
