“A platform,” put in Bob, willing to help her along.

“Yes. But what else could it be called? I’m in earnest.”

“A step,” suggested Sinclair.

“Yes, a step; but couldn’t it be called a stair?”

“It could be,” said Bob, “but I don’t believe it is one.”

“But suppose your erratic uncle chose to call it that.”

“Oh,” laughed Bob, “you mean the stair in the poem.”

“I do. I mean the stair across the hall.”

“What! Oh, I say, Patty, now you’re jumbling up the sense.”

“No, I’m not. I’m straightening out the sense. Suppose Mr. Marmaduke meant ‘above the stair across the hall,’ and meant this stair and this hall.”
