All Bearings and Courses hereafter-mentioned, are the true Bearings and Courses, and not by Compass. Cape Chapeaurouge. Cape Chapeaurouge, or the Mountain of the Red Hat, is situated on the West side of Placentia Bay, in the Latitude of 46° 53' North, and lies nearly West 17 or 18 Leagues from Cape St. Maries; it is the highest and most remarkable Land on that Part of the Coast, appearing above the rest something like the Crown of a Hat,... 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...

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...

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...

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...


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...

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...

I did not come to-day with the idea of bringing you anything new. On the contrary, I have come here to get the inspiration which association with those from the outside gives. There is no hope for this place unless we can keep in contact with the remainder of the United States. In isolation we think in a vacuum, and it is only when we know what you are thinking of on the outside that we get the impulse which leads to construction. I think I can... more...

LEGEND OF THE SEVERN, WYE, AND RHEIDOL. (See Illustration on the Cover.) The Welsh are justly proud of their hills and their rivers; they frequently personify both, and attribute to them characters corresponding with their peculiar features.  Of the Severn, the Wye, and the Rheidol, they have an apologue, intended to convey an idea of their comparative length, and also of the character of the districts through which they flow.  It is... 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...
