ameter. These ropes, which are very easily broken at this stage, are dried, and then twisted tightly, until finally they become as small as threads. Part of the threads are used for the warp, and part for the filling, out of which a strong web of wooden cloth is woven.
weeps and Sprinkles THE automobile street sweeper and
sprinkler is a French invention designed to perform at once two kinds of work ordinarily done' separately. The dust that always arises after a disturbance of the pavement debris, is instantly downed by the almost simultaneous shower of water that follows hard upon the course of the sweeper.
For its cleanliness and labor-saving qualities, the invention commends itself. An automobile is built with a box or tank, having a capacity of 600 gallons of water. A brush, driven by chain and
Calla Lily Farm IN California the calla lily flourishes in 1 superabundant profusion, and attains a degree of perfection rarely ever seen elsewhere. It is cultivated on a very large scale, for the sale of these flowers is immense. During the entire year, the plant flourishes in the open air, and its cultivation has become a very profitable industry. Great crops are raised, and scores of carloads are shipped to the cities and larger towns of California, where a ready market is found. These favorite flowers are also shipped into Nevada and other adjoining States in immense quantities.
What is probably the largest calla lily farm in the world is located in California. There is one 50-acre field in Ventura county devoted exclusively to the cultivation of these flowers. They are planted in long, narrow rows, and are cultivated by means of plows and hoes just like corn or potatoes. The lilies attain a very large size, and are perhaps the most beautiful
repeats the operation. Each cigar is watched carefully during combustion ; and every detail affecting the filler, wrapper, binder, ash, and aroma is noted. The plant from which each cigar is made is known, and the seed of the one making the best showing is selected for future planting
The cigars are placed in “mouthpieces" at the ends of several glass tubes leading to a bottle, which, through another tube, is connected with a flask containing a siphon. The flask and siphon act as lungs-breathing water, however, instead of air. The siphon comes into action when the .flask is filled, the water being gradually drawn off, to be replaced with air drawn through the cigars. A special device is provided to make the action intermittent. Four cigars of average size can be smoked in half an hour.
Machinery has supplanted man's activity in many ways; but not even this product of ingenuity need arouse any fear that machinery is going to invade the sphere of man's “dear delights.”
sprocket, is raised and lowered by a lever at the driver's side. This brush sweeps a strip six feet wide. The sprinkler has a maximum spread of 20 feet. With an empty tank, the machine may attain a speed of 151/2 miles an hour. The motor is of 12 horse-power, and is adjusted to three speeds, 5, 11, and 1542 miles an hour. These speeds depend upon the circumstances under which the machine is working. If the street is wet from rain or other cause, the pavement is, of course, simply swept without recourse being had to the water tank.

A Smoking Machine THE champion cigar-smoker has been
found in the Department of Agriculture at Washington. At each smoking, four cigars are consumed, all at the same time. Were such a record to be credited to any member of the personnel of the departmental staff, probably few of the important results announced from time to time from this center of activity woull be heard of.
This smoker, however, is only a testing machine used for determining the quality of tobacco intended for cigars, with a view to producing an unrivaled quality of the fragrant weed. It smokes the four cigars with more regularity than any man could possibly accomplish the feat. It takes ten seconds steady draw, gives a puff, and after one-half minute

We are now told that radium is perhaps millions of times more powerful than dynamite, and that it is estimated that a single ounce of this substance would have sufficient power to raise 10,000 tons a mile above the earth's surface. Another way of stating the same estimate is this: the energy needed to tow a ship of 12,000 tons a distance of 6,000 sea miles at 15 knots an hour, is contained in 22 ounces of radium.
