Ink used in drawing should always be the best that can be procured; without good ink a draughtsman is continually annoyed by an imperfect working of pens, and the washing of the lines if there is shading to be done. The quality of ink can only be determined by experiment; the perfume that it contains, or tinfoil wrappers and Chinese labels, are no indication of quality; not even the price, unless it be with some first-class house. To prepare ink, I can recommend no better plan of learning than to ask some one who understands the matter. It is better to waste a little time in preparing it slowly than to be at a continual trouble with pens, which will occur if the ink is ground too rapidly or on a rough surface. To test ink, a few lines can be drawn on the margin of a sheet, noting the shade, how the ink flows from the pen, and whether the lines are sharp; after the lines have dried, cross them with a wet brush; if they wash readily, the ink is too soft; if they resist the water for a time, and then wash tardily, the ink is good. It cannot be expected that inks soluble in water can permanently resist its action after drying; [83] in fact, it is not desirable that drawing inks should do so, for in shading, outlines should be blended into the tints where the latter are deep, and this can only be effected by washing.Machinery of application."Yes, sir," he answered, "that will be difficult enough. Everybody has fled, even my own wife and children. I remained because I thought it was my duty, and now I have been tramping through the streets already for over twenty-four hours, without being relieved. It seems that by far the greater number of my colleagues fled also."I found sailors also in Brussels, but for the rest there was only a little military display there. In this town reigned a certain oppressive silence and157 the cafs were not much frequented. The Brussels people did not hide their patriotic sentiments, and nearly every house displayed the Belgian flag, thanks chiefly to the strong attitude of Burgomaster Max. Outwardly Brussels had not suffered by the war; not a house was damaged and nobody had been killed yet. Nor was there lack of provisions, as was proved by the fact that at the "Mtropole," one of the largest restaurants, I paid only seventy-five centimes (sevenpence-halfpenny) for bread, cold beef, and pickles.For manufacturing processes, one importance of steam-power rests in the fact that such power can be taken to the material; and beside other advantages gained thereby, is the difference in the expense of transporting manufactured products and the raw material. In the case of iron manufacture, for example, it would cost ten times as much to transport the ore and the fuel used in smelting as it does to transport the manufactured iron; steam-power saves this difference, and without such power our present iron traffic would be impossible. In a great many manufacturing processes steam is required for heating, bleaching, boiling, and so on; besides, steam is now to a large extent employed for warming buildings, so that even when water or other power is employed, in most cases steam-generating apparatus has to be set up in addition. In many cases waste [31] steam or waste heat from a steam-engine can be employed for the purposes named, saving most of the expense that must be incurred if special apparatus is employed.
