An ingenious Expedient.

“On my way homo from a Western trip I stopped at Duluth,” said a traveler. “The thermometer registered 10 degrees below zero, but building was going on lust the same on a dozen brick buildings, one of which was an ofllce building to cost three hundred thousand dollars. In the East wo shut up shop in the building line in freezing weather, because frozen mortar loses its temper aud is worthless. But out there they lay hot brick in hot mortar; it sets boforo freezing and when set it’s all right. The bricklayors on a building work as close together as possible, wearing protectors on their hands. Beside them are little furnaces and metal-lined mortar tubs, beneath which aro fires. The brloks and mortar are heated hot and laid. A brick, you know, will retain heat for a long while.”
