During the Crimean War, Boydell’s traction machine was used to haul open trucks on the road and across country. Its engine, the “Hercules,” was fitted with a curious arrangement, which, by means of rails attached in six sections to the wheels, enabled it to lay down and take up its own track as it went along. In the South African campaign the military traction engines did some excellent work, and, as they rolled over the plains, startled the Kaffirs out of their senses at the unwonted sight of what they probably thought was some new and monstrous form of rhinoceros. It has yet to be decided what is the best motive power for lorry cars in warfare, both oil and steam motors having, as compared with those driven by electricity, the disadvantage that the machinery moves by a series of shocks. Doubtless the ideal power would be one that acted evenly. The electric motor is superior to all others in the regularity of its action, and its steering is most readily effected. All that is wanted to adapt electric traction to military purposes is a perfected storage battery, and the day may not be far distant when extensive use will be made of light accumulators capable of being safely carried and of being recharged as readily as a steam engine can be supplied with fuel. MOTORS IN AGRICULTURE In England the use of steam for agricultural machinery has hitherto been confined to the purpose of ploughing and threshing. But coal in some districts is dear, and farmers are beginning to find that oil engines are more economical, there being no loss of fuel in the sudden stopping of work during wet weather; but petrol has a nasty trick of not vaporising readily when it is frosty, and here electricity steps in with an admirable _force-motif_. With a dependable electro-motor, the farmer may work his self-binder all day long in the harvest-field, and at-night send it up to market with produce. Moreover, the motor may help to plough and harrow in the winter, and when there is no work to be done it costs nothing, having--unlike the horse--no stomach to fill. In fact, the successful adaptation of the motor to farming may solve the ever-present labour problem, and do much to resuscitate the agricultural industry, while fruit and vegetable growers may find it invaluable, making them independent of high railway rates and bad train service. But, although the application of the automobile to agriculture is only in the experimental stage, it cannot be doubted that, in some shape or other, it will come to the cornfield, the orchard, and the market garden, while the modern farmer will welcome it gladly.
