"Oxygen is in a comparatively mild and harmless state when it is by itself," said Johnny; "but when it gets to combining with any thing it has a great affinity for, it is in a sort of rage. I think myself that there must be some pretty rapid motion going on in a fire, even if we can't see it."
Johnny had handed the chisel to Sue, telling her to put it right back where she found it.
"Well, I will," replied Sue; "but I guess things won't be put back in their right places much after Felix gets here."
Sue had no sooner said this, than she clapped her hand over her mouth. "Oh!" she exclaimed, "if I haven't gone and told!"
Johnny's face had grown very long in an instant.
"Is that your bad news?" he said. "When is Felix coming?"
"I don't know," replied Sue: "you'll have to ask mamma, for she was to decide."
Sue then went back with the chisel, and Alec said,—
"So your cousin Felix is coming again, is he?"
