FORE:One of the problems connected with the handling of material is to determine where hand-power should stop and motive-power begin��what conditions will justify the erection of cranes, hoists, or tramways, and what conditions will not. Frequent mistakes are made in the application of power when it is not required, especially for handling material; the too common tendency of the present day being to apply power to every purpose where it is possible, without estimating the actual saving that, may be effected. A common impression is that motive power, wherever applied to supplant hand labour in handling material, produces a gain; but in many cases the [66] fallacy of this will be apparent, when all the conditions are taken into account.
