IN THE remarkable drawings above, our artist presents a graphic explanation of the effects upon an airship of a severe thunderstorm such as that responsible for the recent wreck of the Shenandoah. In the largest picture is shown how a "line squall" is formed by the meeting of uprushing warm air and descending currents that have been cooled by contact with raindrops and ice crystals of the upper atmosphere.

New Engines for Motor Railways

[no value]
S. W. Clatworthy
WHILE the efficiency and economy of the motor-ship at sea long has suggested the advantage of motor-locomotives, the chief drawback to practical use of the internal-combustion engine on our railways has been its lack of flexibility. In other words, because it is essentially a one-speed engine, it is found incapable of widely varying output of power to meet changing demands.

THE great white stallion snorted, wild-eyed, muscles tensed, his gorgeous mane tossing in the breeze that swept across the vast desert of the Colorado Plateau. Behind their leader a shaggy band of mustangs trembled in terror. Out of the mighty depths of the Grand Canyon rose a humming roar that thundered through the spacious silence of the plateau as a great winged creature shot from the chasm at the North Rim and swooped downward, like a giant bird of prey.

THOSE eight hours out of every 24 that you, like most of the rest of us, spend in the mysterious stupor that we call sleep—what is their purpose? Practically a third of your life you spend in the blank unconsciousness of slumber. Is this really necessary, as physicians long have believed, to rest your tired body and mind and restore your nervous energy? Or is it simply a useless and tragic waste of a third of the precious hours of a lifetime?

William J. Edmonds
You can play host to a surprising number of birds this winter if you spend the small amount of time necessary to make a simple bird-feeding shelter and keep it well stocked with suet and seeds all through the cold months. The shelter illustrated is not only substantial and well designed for its purpose, but also is sufficiently simple in construction to be made by any one with the common tools found in every household.

PROFESSIONAL photographers obtain high gloss effects on photographs by allowing the prints to dry on polished ferrotype plates. The amateur can do the same thing in the way illustrated. When removed from the bath, the prints should be placed face down on the bottom of a developing tray and the excess water removed with a blotter and roller.

PLASTER of Paris, which has many uses in the home workshop, may be hardened and toughened by mixing it with a diluted glue solution instead of water. The mixture also sets more slowly, which is sometimes an advantage. Plaster casts can be made more or less weatherproof by painting with three or four coats of linseed oil, each coat being allowed to dry before the next is applied.

DAN GERRITY
BEFORE puttying a new pane in a window, I fasten the glass in place with old phonograph needles. I find these are easier to drive than the regular V-shaped glazier’s points. Phonograph needles are equally useful in holding picture-frame backs in place and for other purposes when very sharp steel points are needed in the home WORKSHOP.
