Grinding, no doubt, if traced to the principles that lie at the bottom, is nothing more than a cutting process, in which the edges employed are harder than any material that can be made into cutters, the edges firmly supported by being imbedded into a mass as the particles of sand are in grindstones, or the particles of emery in emery wheels.¤¥ª¡¥¤¥Á¤¤¥

An engineer may direct and control work without a knowledge of practical fitting, but such control is merely a commercial one, and cannot of course extend to mechanical details which are generally the vital part; the obedience that may thus be enforced in controlling others is not to be confounded with the respect which a superior knowledge of work commands.¥¤ê

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.¥¥¥¤¥¤¤

When I was half way between Liège and the Netherland frontier, I noticed that the village of68 Vivignes was burning in various places. It is a beautiful spot, quite concealed between the green trees on the slope of the hills, west of the canal. And the finest and largest farms were exactly those ablaze. The fire crackled fiercely, roofs came down with a crash and a thud. Not a living being could be seen. From the windows of the burning houses small white flags hung, and they too were one by one destroyed by the fire. I counted forty-five farms that were burning, destroyed by the raging flames.ÏÞ©ß

It is well for an apprentice to invent or demonstrate all that he can—the more the better; but as explained in a previous place, what is attempted should be according to some system, and with a proper object. Time spent groping in the dark after something of which no definite conception has been formed, or for any object not to fill an ascertained want, is generally time lost. To demonstrate or invent, one should begin methodically, like a bricklayer builds a wall, as he mortars and sets each brick, so should an engineer qualify, by careful study, each piece or movement that is added to a mechanical structure, so that when done, the result may be useful and enduring.Óè¥Õ¥»
