HIS FIRST AEROPLANE

T is hard for "grown-ups" to realize that to our children the art of flying is accepted quite as a matter of course, just as we accepted roller skating or swimming. This photograph shows a child of the twentieth century, a six-year-old, at work on his first airship, a monoplane with propeller in front. The youngster watched the aviators skimming through

the air at the Los Angeles aviation meet
and has been experimenting with flying
machines ever since. You and I were
trying to construct a top schooner or a
coaster at that age but none of us ever
dreamed of building monoplanes. The
generation to which this small chap be-
longs will probably perfect the new sci-
ence, simply because they will regard
flying as a matter of fact instead of as
a startling novelty.

man cannot get in long enough to chop a hole in the floor so as to set in the pipe. When the pipe is set down in the hole it is in a position which sends an inch and a quarter stream directly up to the side of the opening, driving away the heat and smoke. The operator by turning the wheel in his right hand a quarter of turn changes the pipe from one position to another in less than a second, covering about 300 feet and all the ceiling.

If conditions are such that a man can

not get in on the first floor to chop a hole he can break the basement windows and get the pipe through.

The amount of water from an inch and a quarter nozzle, with 150 pounds of pressure behind it makes this the coolest part of the building, as it drives away the heat and smoke. A half turn of the wheel on top will send this powerful stream over 150 feet either way. Each pipe has a set of spikes to hold it to the floor in case it is desirable to use 200 pounds pressure. A set of hooks are

employed to break the deadlights, to hook the pipe to them, so that if the wall looks bad the men can leave the pipe and still have a powerful stream in any direction they wish to leave it.

HAVANA'S NOTABLE FLOODS

The

AHURRICANE which also did great damage along the Atlantic seaboard of the United States flooded the streets of Havana, making boats the only safe method of transportation. People were rescued from their houses by patrol wagons and then, when this became impossible, in boats. The financial loss in Havana alone as a result of this flood was more than one million dollars. coal docks were wrecked, customs houses and wharves flooded and lighters and barges sunk in the harbor and valuable household effects in houses in the submerged districts ruined. For several days. communication by Havana with the interior was cut off so great was the flood and the destroyed telegraph and telephone system. While the damage to property in Havana was so great fortunately only two lives were lost, two men being drowned in the harbor.

The group in the picture seem to be posing as contentedly as if standing on dry land.

GUAYULE SHRUBS IN TEXAS

SINCE the discovery was made that the

guayule shrub contains ingredients from which a high grade of crude rubber may be manufactured, the industry of gathering and baling the shrubs has become very important in the upper Rio Grande border region of Texas where it grows in more or less profusion. This desert shrub was considered more than worthless a few years ago. The ranchmen despised it because it was unfit as forage for their cattle, and it was a menace to the raisers of sheep and goats for the reason that these animals would eat the branches of the shrub and die from indigestible balls of rubber that formed in their stomachs. It grows only upon the poorest land, being found chiefly upon the limestone ridges. With the establishment of a rubber factory at Marathon, Texas, in the heart of the guayule shrub territory, a large demand for the shrub was created. Many men are employed in cutting, baling and hauling the shrub to the factory. Large shipments of the shrub are also made to other factories. Land that was formerly non-productive, even of grass, is now bringing in a handsome revenue from the shrub which it produces.

The discovery of the virtues of the guayule shrub is merely another addition
