The plows on the elevated arm face in the direction from which the plow is coming. When the end of the field is reached, this arm is lowered, and the plow starts back. DEVELOPING ENGLISH PLOWS FIELDS choked with seeds or covered PORTABLE ICE PLANT FOR VILLA with high stubble, or with manure, GENERAL PANCHO VILLA re A balk ordinary shallow steam plows. new English steam disk plow has been brought out to overcome this. The balance gear of most broad shallow plows has caused the trouble, because the weight of that half of the plow which is elevated has the tendency to cause the other half to jump from its work, particularly when the speed is high and when plowing shallow. The new plow overcomes this drawback by means of a device whereby the center of the plow is automatically shifted by the pulling strain, and the center of gravity thus placed directly over the working parts. One of the new English models carries two gangs of plows, pointed in opposite directions. Thus the plow can be worked back and forth over a field. cently bought a portable ice plant for hospital service. The sick and wounded, ill with fever, will receive great benefits from ice packs and ice water made by this machine. It is not General Villa's intention to operate the machine while it is in transit, except when it is loaded on flat cars. When the plant is taken over rough country, they will operate it only during encampments. One truck has the compressor, gasoline engine, cooling tower, condenser, and centrifugal pump, all set on two inches of cork-board to make a cushion for the machine and to eliminate vibration. The gasoline storage tank is swung under the rear end of the truck. The cooling tower is between the engine and compressor. The other truck carries the tank. This screen and several like it are covered with birds which dashed themselves to death against the illuminated faces of the clock on the Philadelphia City Hall. CATCHING BIRDS IN AN UN INTENDED TRAP TRAGEDIES of "the heavens above" are not confined to aeronautic fatalities; for any visitor to Philadelphia's mammoth but unsightly City Hall may learn, through ocular proof, of yet another source of aerial death. He will be shown three screens, against whose white surfaces are mounted some two hundred birds-owls and orioles, woodpeckers and wrens, robins and redwings, ducks and doves, swallows and sparrows galore, a thrush or so, and an occasional titmouse-well nigh the full catalogue of the feathered denizens of the Middle Atlantic States. These birds have all been picked up, dead, on the balcony beneath the great clock whose faces glow out from the central tower of the building, or on the upper roofs-mute witnesses of the enduring truth that not only moths and men are dazzled to their deaths. heat of the dishes and the tank, together with the heat of the rinsing water in its bottom, quickly dries the entire batch of dishes, so as to obviate the necessity of drying each individual piece. As a means of stopping the exodus of the married woman from the kitchen to the business or professional office, this type of invention probably has no superior. If "woman's place is in the home", the home cannot have too many of such mechanisms installed to lighten and shorten the hours of drudgery that MAKES DISHWASHING A JOY housekeeping frequently necessitates. NE of the most disagreeable ΟΝΕ features connected with household duties is the task of washing a big batch of dishes several times a day; yet the large mechanical dishwashers now in use on ocean steamships and in first class hotels are too large and cumbersome to be suitable for use in private homes. But what seems like an ideal method of washing dishes has been brought forth in a recent electric dishwasher. The dishes are placed in a specially constructed wire rack, which is circular in shape and fits around the central cylinder inside of the washing chamber. From the top of the cylinder a circular wire basket in which glasses and silverware are placed, is suspended. Beneath the tank is a centrifugal pump driven at high speed by an electric motor; this circulates six to eight quarts of hot, soapy water necessary for washing at a rate of about thirty gallons a minute, under six pounds pressure. The hot water splashes among the dishes in the tank for less than a minute; the drain is then opened and the water drawn off. Fresh hot rinsing water is run in and the dishes are rinsed for a few seconds. The combined KITCHEN WORK IS NOTHING BUT FUN WHEN THE MACHINE IS This simple device washes the dishes, thus eliminating one of the By C. M. MORRISON The wonders of the steam engine, the telegraph, wireless, the flying machine may be some day regarded as insignificant compared with the extraordinary "Remembering Machine". While its creator-S. Bent Russell of St. Louis —makes no extravagant claims for it, nevertheless, the machine has possibilities so astounding as to make one gasp in contemplating them. Perhaps the “Remembering Machine" solves the riddle of the ages, How can man practically rid himself of all unpleasant labor? A detailed description of the workings of the mechanism is given immediately following this article, on page 496.-The Editors. O IL oozes slowly in thick, viscous streams from the great lathes, as they turn slowly but irresistibly in their relentless power; overhead the smooth, worn belts speed briskly and slap at the ceiling. The hum of a thousand machines fills the air; the confusion of whirling arms and belts and cams. bewilders the eye. The great factory is jammed with equipment. In fact, so close are the machines to each other, that there is barely room for a man to thread his way among them. There is no need for room, because on the entire floor, in all that maze of flying steel, not one man has a place. It is the strangest factory on earthfloor after floor of complicated machinery, without a man to guide it. Magnets are attached to the controls of each, and in front of some of them are curious rows of glass bulls'-eyes; and that is all. A maze of wires, bound together into four cables, each thicker than a hogshead, leads into a seven-story tower at one corner of the plant. The entire maze of machinery is controlled from this tower. But, more marvelous than the factory, even the tower is not filled with operators, each with keys and switches in front of him with which he controls some part of the machinery. Instead, it looks like a huge telephone exchange; for every floor is filled with neat rows of complicated mechanism, with parts that grind slowly and steadily, others that shoot into place with quick snaps that punctuate the purr of the mechanism like rifle shots, and above all is the insistent swish of rushing water, and the flash of opening and closing electric switches. This huge maze of machinery in itself is running the entire factory, taking in the raw material, making it up, casting out defective pieces, packing, sorting, and storing the finished goods, without the intervention of a single human being. As a matter of fact, no such factory exists. It is a mere dream of the scientist; but it is a dream that now may actually be realized. Man may now be able to construct just such a mechanical brain as that installed in the imaginary tower-a brain which thinks, analyzes, judges, decides. These are all possible, as the logical development from a single extraordinary invention made by a St. Louis engineer-S. Bent Russell by name. Jacques Futrelle, who went down with the Titanic, created a "Thinking Machine"-a semi-psychic, semi-human, imaginary detective with a machine-like brain in a long-faced skull. Robert Houdin, the famous French necromancer, devised an automaton in the form of a man that would sit at a table and answer, by writing or drawing, any question put to it. Vaucanson's artificial duck, invented in 1709, "stood on its legs, moved its head to the right or left, drank, dabbled its bill in the water, quacked like a living duck, put out its head to take up seed, swallowed the latter, and would lay an egg for the edification of the spectators," according to a court chronicle of the time. But none of these marvelous devices even approaches that of Russell's. Anyone could see that the machines were run by clockwork; and not even the most fanciful writer had dared to dream of a machine that could actually think. And yet that is just what Russell's machine does. And the word "think" does not mean, as it usually does when applied to machin ery, that the device performs some intricate mechanical operation; it means that the machine possesses real intellectual powers, comparable to those of the living animal. In fact, the intellectual power of the machine, in its present state of development, may be compared to the powers of a baby that is just learning to look around, and to cry for food; and just as development will increase the mental powers of the child, so perfection of the machine will increase its ability to think. The way in which the human brain acquires its habits of doing things may be compared to the action of current in a telephone exchange where the wires are not perfectly insulated from each other, and where, consequently, current leaks S.
