service during the days of earthquake and fire at San Francisco. This government station has a Postal Telegraph wire in connection and while every other Postal office as well as Western Union and every telephone wire was placed out of commission this one retained communication with Seattle and Portland for three days over an accidental cross in the wires. The Pacific fleet steaming northward from San Diego to Long Beach, were notified of the great catastrophe by wireless from this station. Plans for the landing of a force of bluejackets and marines and supplies of food and medicine were completed while the

This interesting duplicate locomotive is 10 feet long, 5 feet 4 inches high and 3 feet wide. The boiler is formed of four number 9 round washboilers, with one galvanized wash tub for the flaring portion. The cab was formed out of four cake boxes, with a curved stove board for the roof. The eccentrics and working gear were represented by transom lifts and brass tubing of paris green sprayers.

The complete list of utensils and small hardware which went into this locomotive is as follows: Two stove boards, three waiters, two oil stove ovens, three coils hose, nine patty pans, one egg beater, one pint cup, two conductor elbows, one milk pan, one fruit press, seven milk skimmers, two creamers, two door stops, two dampers, two clamps, one A.

ships were still three hundred miles away. When the Chicago, flagship of the feet, arrived and took up anchorage off Fort Mason, where General Funston had established his headquarters, the burning city obtained direct telegraphic communication with the outside world by means of wireless to Yerba Buena and then to the East over the abovementioned Postal wire.

well-drilled and well-equipped modern army; and here is photographic evidence of this development. The Chinese soldier looks strikingly like his Jap cousin, and, in fact, is being trained by Jap officers, to a large extent. Because she is developing a new army, and knows that it is a good one, China has lately been threatening to drive Russia out of all Chinese territory.

There seems to be no reason why the Chinese, when properly drilled and officered, should not be classed as among the world's best soldiers. They are quick to learn, are obedient and possess patience and endurance.

By. paying out a sufficient length of line, the kite may be made to touch at any depth. As soon as the water shoals to the depth at which the kite is set, the latter, touching the bottom, causes a signal to be given in an apparatus installed on deck.

As seen from Fig. 1, the kite is designed like a roof with its planes aslant against the motion of the vessel, so as to cut down into the water when the latter is moving. It thus sinks to the bottom in the same way that an air-kite rises in the air. The wire to which the kite is fastened is kept strained, taking the shape Fig. 2.

In fact when giving out as much of the line as corresponds to a certain depth of water, the lead will give a signal immediately the vessel gets into shallower water. The depth may be ascertained at any time by slowly giving out the line until the lead strikes bottom. And, finally, the lead may be used in connection with observations to be used for pricking charts, and

Not all, however, care to hurry life insurance along by testing mancarrying machines. Here is another line of endeavor for such.

Everybody has seen a bird soar and a few observers have spent a good deal of time and energy wondering how it is done. If they never tried to imitate they are probably still wondering, for mere watching the birds will never teach us to fly. A machine that will imitate the birds and give to a beginner his first lessons in flying is easily made out of inexpensive materials as shown in the sketch.

It is made of heavy drawing paper cut into the shape shown and braced with a thin piece of wood glued on top. The weight which is glued to the bottom of the model and which corresponds to the body of a bird may be made of any piece of wood or rubber shaped so as to present the least possible resisting surface to the action of the wind. The wings are curved as shown in the end view and the
