"Absolutely impractical," he declared. "The only feasible plan would be to take out the north partition and build an extension like this."

"That couldn't be done," said Dan, "on account of the projection."

Whereupon, such is the power of opposition, Mr. Clarke set himself to prove that it could. For over an hour they wrangled, going into the questions of cost, of time, of heating, of ventilation, scarcely looking up from the plans until a figure in a checked suit flung open the door, letting in a draught of air that scattered the papers on the desk.

"Hello, Dad," said the new-comer, with a friendly nod to Dan, "I'm sorry to disturb you, but I only have a minute."

"Which I should accept gratefully, I suppose, as my share of your busy day?" Mr. Clarke tried to look severe, but his eyes softened.

"Well, I just got up," said Mac, with an ingratiating smile, as he smoothed back his shining hair before the mirror in the hat-rack.

"Running all night, and sleeping half the day!" grumbled Mr. Clarke. "By the way, what time did you get in last night?"

Mac made a wry face.

"Et tu, Brute?" he cried gaily. "Mother's polished me off on that score. I have not come here to discuss the waywardness of your prodigal son. Mr. Clarke, I have come to talk high finance. I desire to negotiate a loan."

"As usual," growled his father. "I venture to say that Dan Lewis here, who earns about half what you waste a year, has something put away."
