PREFACE. If the River Nidd and the brooks adjacent, in the vicinity of Knaresbro’, up the valley to Ramsgill, near Pateley-Bridge, and near the adopted line, had not possessed the many water-falls, and given motion to the sixty-seven mills which they do;—or had the great landed proprietors, on the line now adopted been hostile to this all improving project, of this highly favoured and not less honoured, their native... more...

THE RURAL MOTOR EXPRESS. The transportation burden on the railroads and highways of the country has been tremendously increased by the war. There is a larger load to be carried, of manufactured goods, raw materials, and foodstuffs. Not only has production of manufactures, raw materials, and farm products increased, but it is now necessary to transport a much larger proportion of these goods over long distances. The burden is further... 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...

To increase the highways transport resources as one of the means of strengthening the entire transportation system of the country, and for the purpose of avoiding the waste incurred by running transport vehicles empty, return-load bureaus are established. These bureaus are a means of bringing together the shipper having goods to move and the operator of an empty vehicle which is possibly running to the point for which the goods to be shipped are... more...


The carbureter measures the fuel charges for the engine and automatically mixes them with the proper amount of air to form a highly combustible gas. The Marvel Model "S" Carbureter is of the automatic air valve, heat controlled type. Its outstanding advantages are: 1. Simplicity of construction and operation. 2. Quick starting in any weather. 3. Automatically controlled heat application to ensure complete vaporization of fuels. 4. Economy in... 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...

CHAPTER I.INTRODUCTORY North-West Donegal.  A fine afternoon in September.  The mountain ranges were bathed in sunshine and the scarred and seamy face of stern old Errigal seemed almost to smile.  A gentle breeze stirred the air and the surface of the lakes lay shimmering in the soft autumnal light.  The blue sky, flecked with white cloudlets, the purple of the heather, the dark hues of the bogs, the varied greens of bracken,... more...

Mr. Chapin and Gentlemen: It would be a truism to say that I have always been interested in transportation. It has always been a subject of keen interest to me, I presume, because I was born with it. By the fortune of birth I came to live in a region where transportation has been through every one of its stages in this country. If you go back into the history of the Colonies, you will find the two first lines of through transportation in America... more...
