VALUE INDIAN WHEAT HAS FORAGE trically-driven wrecking outfit, the first of its kind devised. It not only takes current from a third rail third rail but is equipped with storage batteries of two hundred and thirty cells. All the equipment of the "INDIAN wheat," which is common but very much smaller, and is rich in protein. It occurs most abundantly in early spring in INDIAN WHEAT, KNOWN TO ONLY A FEW, HAS A RANGE FROM CANADA TO MEXICO wrecker and the car itself can be oper ated for sev eral hours' time away from any source of power. The new wrecker is double-ended, with a power ful crane on each end and, in addition, is equipped with four power operated outriggers, or extending beams, for additional stability when lifting heavy loads. The outriggers are located two on each end of the car and when not in use can be run back or drawn in, and do not interfere with the progress of the car. The wrecker was especially designed by an industrial firm of Bay City, Michi gan, to meet conditions at the terminal. The car itself is swung low, which enables it to pass through all the tunnels and low bridges of the lines. The booms at each end swing through a radius of one hundred and eighty degrees, and can both be operated at the same time or separately. The cab at each end of the car controls the corresponding boom and the propelling apparatus as well. As all of these are controlled by air there are no heavy levers required. No time is wasted in turning the car and, being its own locomotive, it is able to arrive on the scene of a disaster about an hour earlier than the time required by the old style locomotive-drawn wreckers. ROOF GARDEN WITH ROOF gardens are common on the bigger hotels in most large cities, but it is claimed that from this one in Salt Lake City the views on all sides are unsurpassed in picturesque wild beauty. In the photograph the view is to the southeast, across the city, with the Wasatch Mountains a few miles distant. A western view looks across twenty miles of wild desert onto the Oquirrh Range, where the greatest open-mine operations of the world are. being carried on. North, a short arm of the great Wasatch Mountains comes down close to the hotel, rising, in rugged wildness, for fifteen hundred feet above the city level. South, for fifty miles, stretches the beautifully fertile Salt Lake Valley with the great Utah Lake in the far distance. Northwest, the landlocked briny Salt Lake, studded with its strange islands, lies amid the gigantic rocks which form its shores. EXHIBIT OLD ELECTRIC THIS "grand-daddy" of all electric vehicles has just been presented to the New York Electric Vehicle Association. The machine was built in 1893 THREE-WHEELED VEHICLE SAID TO BE THE ANCESTOR OF ALL ELECTRIC CARS The machine was built in 1893. and still has the same pneumatic tires that were put on when it was made. It is an oddly wrought three-wheeled contraption, steered with a tiller by a single wheel in the rear, like a ship's rudder. There are only two speeds, and the machinery is set on the front axle. The storage battery is carried under the seat and in the body. The name of the inventor is not known. THE TRAFFIC OFFICER OF THE TRACKS His idea was to have a light, efficient battery, with as light a frame as possible, and the main object seems to have been to obtain speed. The machine was rigged up for service and tried out before a curious crowd of onlookers. At the same time, a modern electric car was photographed with it. He blows the whistle to warn the workmen when a train approaches. WHISTLE TO SAVE LIVES BECAUSE he proved to the Lehigh Valley Railroad Company that section foremen and construction foremen should carry a whistle, W. T. Morris, who has that kind of position himself, got a month's vacation with pay. The railway gives prizes for "Safety First" ideas, and this man showed that the lives of construction hands could be saved if the foreman had some efficient means of letting them know when danger, in the shape of an oncoming train, approached. Gate tenders have also been provided with whistles so that they may more easily warn people when they attempt to cross tracks when gates are lowered. MAMMOTH BUBBLE OF LIGHT A By L. R. PERRY MONG the mass of structures erected at the Panama-Pacific Exposition in San Francisco, will stand one, conspicuous in the daytime because of its odd and beautiful form and, at night time, because of its illumination. This center of interest will be the mammoth glass Palace of Horticulture. By day, it will stand out as as a great fairyland castle in the midst of the myriad colored tropical South Gardens, toward the western end. By night, the entire structure will glow as a mammoth self-illumined bubble-a phosphorescent opal. Here will be found the latest and, per- ern science oped-illumination by means of "wells of light". This structure, six hundred and thirty feet long and two hundred and ninety-five feet wide and costing three hundred and sixty thousand dollars, will cover five acres of ground. Several naves will pass through it; over the center the largest steel and glass done in the world will tower one hundred and eighty feet. On the exterior of this dome, in the daytime, a huge flower basket twenty-six feet high and weighing over one hundred tons will be noticed crowning the top as a sky ornament. The term "crystal palace" seems the most fitting term that can be applied to the entire edifice. A GREAT DOME WHICH IS REALLY A MAMMOTH BUBBLE OF LIGHT The effect at night of a mammoth glowing bubble or iridescent opal, is obtained in the following manner: Within the building, at the base of the dome in the center, will be an eighteen-foot ornamental tower. About the base of this tower will be placed a number of searchlights directed to.ward the great dome above. The rays of the lights will pass through a large "diffusion plate" borne on top of the tower, composed of a small number of small lenses which, while causing a beautiful dispersion of the rays by refraction, will not break them into their prismatic colors. In one part of this building, Festival Hall, two of these beams will be reflected from mirrors before passing through the plate, in order that they may be brought to bear upon the lower areas of the building walls. All the light will be reflected back from the dome and walls, filling the building with an evenly blended light with the source entirely concealed. The interior illumination will also provide an exterior effect, as, in front of one of the searchlights hidden at the base. of the light well or tower, will be a revolving glass plate of red, green, and yellow sections, which will send a constantly varying surge of color against the dome of opalescent glass. Another revolving plate, opaque with the exception of one quadrant, will break the waves of color with a pulse of white light passing through it, and the effect will be exactly that of a great opal shot through with warm changing colors. WHITE IN THE OPERATING ROOM MUST GO W By J. A. WHITMAN HITE is supposed to stand for sanitation and cleanliness and, for that reason, hospital boards in in the past have insisted upon this effect, sometimes, perhaps, to make a show place of the most dramatically interesting department of the hospital. Today the most modern hospitals administer, in the majority of cases, continuous gas. This cannot be given in an ante- or preparation room. The patient, therefore, must be taken directly into the operation room in a perfectly conscious condition. The effect upon the patient about to go under the knife, on being wheeled into this atmosphere of blinding snowy whiteness, is that of shock and terror. Op the top floor of the building, where every available bit of sunlight is reflected. A frequent comment of the patient later on is, "How frightened I was when I saw all those nurses and doctors in white clothes in that terribly white room." But it is not altogether the psychological effect on the patient that the up-todate surgeon is thinking of when he advocates abandoning white for green. It is the effect upon himself that he is considering, and it is right and proper that this should be his viewpoint. To him is entrusted the fate of human lives. His full attention must be absolutely concentrated on the task before him. Anything that tends to disturb him, to lower his efficiency, reacts directly on the patientin other words, imperils the patient's |
