PREFACE The people of the United States are engaged in the solution of the railroad problem. The main question to be determined is: Shall the railroads be owned and operated as public or as private property? Shall these great arteries of commerce be owned and controlled by a few persons for their own private use and gain, or shall they be made highways to be kept under strict government control and to be open for the use of all for a fixed,... more...

The Wright Brothers’ Aeroplane By Orville and Wilbur Wright   THOUGH the subject of aerial navigation is generally considered new, it has occupied the minds of men more or less from the earliest ages. Our personal interest in it dates from our childhood days. Late in the autumn of 1878 our father came into the house one evening with some object partly concealed in his hands, and before we could see what it was, he tossed it into the... more...

TUESDAY LECTURE The Compass Everyone is supposed to know what a compass looks like. It is marked in two ways—the old way and the new way. Put in your Note-Book this diagram:   The new way marked on the outside of the diagram, starts at North with 0°, increases toward the right through East at 90°, South at 180°, West at 270° and back to North again at 360° or 0°. The old way, marked on the inside of the... more...

American railroads of the early 19th century were cheaply and hastily built. They were characterized by inferior roadbeds, steep grades, sharp curves, and rough track. In spring, poor drainage and lack of ballast might cause the track to sink into the soggy roadbed and produced an unstable path. In winter this same roadbed could freeze into a hard and unyielding pavement on which the rolling stock was pounded to pieces. In those pioneering times... more...

Screw Propellers from 1858 to 1862. During the maple sugar season of the spring of 1858, a well-to-do farmer, of western New York, whittled out a spiral or augur-like screw-propeller, in miniature, which he thought admirably adapted to the canal. He soon after went to Buffalo, and contracted for a boat to be built, with two of his Archimedean screws for propulsion by steam. Although advised by his builders to substitute the common four-bladed... more...
