Giant Engines Point to New Era in Transportation
A story of the remarkable struggle between steam, electricity, and oil—Marvelous inventions may mean cheaper travel by rail and sea
[no value]
[no value]
Hawthorne Daniel
DEVELOPMENTS in transportation during the last few months all seem to point to the ultimate subordination or elimination of steam as a direct source of power for the movement of ships and trains. Significant of this trend was the recent arrival from Great Britain of the motorship Aorangi at the Panama Canal and later at San Francisco, and the keen interest of American engineers in this beautiful 23,000-ton passenger liner driven by internal combustion engines.

Robert E. Martin
HAVE you ever tried to walk a chalk line? If you have, you probably found it difficult. The reason is obvious—your supporting base was narrowed, and you had to support your body almost on a point. But can you walk in a straight line employing your usual gait, with feet at a normal distance apart?

Arthur A. Stuart
PARIS bids fair to be the first of the world’s largest cities to solve its rapid-transit problems high in the air. Recent reports from the French capital indicate that actual construction work soon may begin on a remarkable, high speed aero-railway, along which propeller-driven cars suspended from head monorail will travel 60 miles an hour, carrying thousands of commuters between Paris and the suburb of St. Denis.

MORE than half a million acres of national forest lands laid in waste by flames! These startling figures set 1924 down as one of the most critical years in the experience of the United States Forest Service. Growing carelessness on the part of the campers, combined with long sustained droughts are given as the cause.

MANY novel features are incorporated in a new method of producing moving pictures for non-theatrical use developed by Thomas Armat, of Washington, D. C., who was a pioneer in the development of the moving-picture projecting machine. The new process involves a camera, a projecting machine, a new kind of moving-picture film, and new ways of taking and showing pictures, which permit one-eighth of the usual quantity of film to be used.

URGENT need of houses that can be rented at prices a workman can afford to pay, has brought about a new type of steel home in Great Britain, principally in Scotland. They can be erected, largely by unskilled labor, almost overnight. Three motor-trucks are said to be sufficient to carry the materials for a complete house from the factory to the site.

MAKING children eat bread crusts may be a useful practice from an economical standpoint, but the time-honored belief that the crusts possess better dietary qualities than the center of the bread seems to have scant basis in fact. This was revealed in some interesting experiments just completed by Professor Roscoe Hart Shaw of the American Institute of Baking.

THE inverted V between the lower legs of the sawbuck illustrated makes it exceptionally strong and rigid. If made of hard, heavy wood, it will hold as large a log as two men can handle. The buck also has the upper part clear for the passage of the saw and it can be made long enough for a piece equal to two sticks of the finished wood to lie across its horns.

EDWIN M. LOVE
WHEN heavy objects must be lifted on a truck without the aid of winch or tackle, it often is possible to use the method illustrated in the accompanying photographs. These show how a heavy stump was loaded by three men. The chain was tightened and the stump rolled up the incline once more, when it was possible to pry up the lower ends of the planks until they were nearly level with the truck bed.

ROBERT PAGE LINCOLN
IF YOU are in the habit of carrying your fishing-rods without any protection save thin canvas cases, sooner or later they will come to grief in transit. A tube for two fishing-rods can be made readily out of a length of round galvanized iron rain-spout tubing about 3 in. longer than the rods when they are unjointed.

After the springs are in place, whether sewed to webbing or held in the manner explained, the next step is to tie the tops in a position to give the seat its shape. Figure 3 shows the springs tied and the worker driving the last tack. In this particular operation you should keep in mind how the original job was tied and do the new work accordingly.

A SMALL portable electric motor or a fan motor can be adapted easily for removing varnish from floors, sandpapering the wood, and waxing and polishing the finished surface.

Charles Kugler
EASILY as it may be made, this fixture makes possible the speedy grinding of U.S.S. or 60-deg. thread tools and Acme or 29-deg. tools. Either type of tool can be ground at one setting. For example, to grind a 60-deg. tool, the sides A and B are placed on the magnetic chuck of a tool-grinder and the C is used only when a U.S.S. tool is desired to make a flat on the thread.

MOST lathes have two pans for chips, one for iron and one for brass. If your turning is mainly iron, the trouble of changing the large pans can be saved by making a small pan that just fits in the opening in the bed under the chuck. The majority of lathes have a flange at the bottom of the bed that will hold the pan.
