THE ELECTRIC REMEDY

"Get Professor Henderson!" directed Jack, "Where is Mr. Roumann, Washington?"

"In heah!" exclaimed the colored man, pointing to the shop. "He am all blowed to pieces!"

Jack and Mark were terribly afraid. The smoke of the explosion hung all about. They rushed through it, and into the shop. Part of the side of the wooden building had been blown out.

"Where is he?" asked Mark. "I can't see anything."

"Over here," called Jack, as he saw a huddled heap in one corner. As the smoke cleared away he could see pieces of machinery scattered all about.
