/"\NE of Japan's principal industries is ^ that of silk culture, and this is certainly well represented at the White City. By means of models, photographs, and charts every process of sericulture from sweeping the egg-cards to the removing of the woven fabric from the loom is minutely shown. What is claiming no little admiration in this section is the wonderfully realistic representation of Fuji-yama, the sacred mountain of Japan, built up of hundreds of thousands of silk cocoons. As the model is 180 feet in length and towers some 18 feet in height it will be seen that it is a no mean attempt to reproduce this famous mountain.



^~V\*E of the most curious of American archaeological riddles awaits solution in Northern New Mexico, a few miles from the Indian Pueblo of Taos. Large, rounded cobblestones are unusually abundant for a locality so far from the river, and the cobblestones are distributed with a system and regularity that makes it certain that they were placed by human hands. They are arranged, for the most part, in rectangles, with here and there a circle, covering an area not less than twenty-five square miles in extent.

It is plain that these were the foundation stones of an adobe city, but nowhere else in America have ruins been found of any prehistoric city at all approximating this in size. How long ago it flourished, or by what sort of people it was inhabited, is a point upon which the myths and traditions of the Southwestern tribes are silent. The Pueblo of Taos is known to have occupied its present site for at least four hundred years.

Lighting Gas By Pistol. Ingenious arrangement of flint and steel for use of housekeepers.


""THE story is told of an old lady who saved matches by keeping the gas burning all the time, and yet ridiculous as this may sound, the millions of matches manufactured each year by the numerous match factories in this country, bear silent witness to the fact that it is no small item of expense in American life. In order to eliminate the necessity of carrying the match a versatile inventor has revived the flint and steel of our grandfather's day and placed it upon the market in a new and unique form. The lighter looks like a pistol and is so constructed that when a trigger is pulled a steel bar, having its surface roughened, issues for a short distance from the muzzle and in doing so passes across a piece of flint. This produces a shower of sparks sufficient to light any gas jet.

EXPERIMENTS made at the United States government's plant testing gardens at Fort Brown, Texas, in growing the Japanese tallow tree have proved so successful that many of these trees have been distributed among the farmers of the lower Rio Grande Valley section and considerable attention is being devoted to their cultivation. It is stated that the nuts of these trees contain an oil which is used in the manufacture of a high grade of varnish and that the product is in great demand in this country. The climate and soil of the extreme southern portion of Texas where the trees are being grown seems splendidly adapted to them. The trees, of ornamental appearance, are of quick growth.

BUILDING A CONCRETE BRIDGE IN A DAY. Remarkable scene on the Pennsylvania, where a bridge was built in a day at York, Pa., without delaying trains.

[graphic][merged small]


DROBABLY never before in the history of railroading has a permanent bridge been erected as quickly as that, recently built by the Pennsylvania Company in the suburbs of York, Pa. It is built of nine large slabs of reinforced concrete, which after being molded to exact dimensions were placed alongside the railroad, convenient to the bridge that was to be replaced. At the appointed time two immense steam cranes, mounted on cars, tore up one-half of the old bridge bodily, tracks, spans and all, and deposited it on the solid ground. One by one the great blocks of concrete were lifted into place, but so rapidly was the work accomplished that in thirty minutes after the first half of the old bridge was removed the new section was there to take its place, with track all- laid ready for the passage of trains.

The other half of the bridge was replaced in much the same manner, and the entire structure was completed in a single day and not a single train delayed on account of the work, and the bridge is located on one of the busiest sections of the road, trains following one another very frequently.
