Every building in the path of the fire that was not of steel construction was leveled to the ground, only a mass of debris being left to give evidence of what once was. Thus it follows that modern fireproof construction will enable a burnt building to stand while others will fall. On the other hand, the inadequacy of steel-frame buildings as at present constructed, was made manifest in the fact that the fire was able to come in at the windows, and everything was burnt entirely out, from basement to cornice, except the steel skeleton. Therefore, as in this case the window openings proved to be the vulnerable points where the fire was admitted, and as no building is strictly "fireproof" so long as it is possible for fire to shoot in at any opening,

It was the thorough knowledge of mechanical and locomotive engineering, acquired in the United States, which made it possible for John Magill to go back to Russia and rise again to a more than princely estate.

Prince Michael Hilkoff looks like a typical down-east Yankee of the old school. In the proper costume, he might easily pose as Uncle Sam himself, for his short white goatee, and his thin, erect figure, with its broad shoulders and long legs and arms, are all in character.

He has paid, in all, three visits to the United States. He came first in 1857. At that time he was a young Russian swell of twenty-one. While a student at the University of St. Petersburg, he had read, in a French translation, the Leatherstocking novels of Fenimore Cooper, and they had first aroused his interest in the wonderful country beyond the ocean.
