ONE:Second.The manner of moulding and its expense, so far as determined by the patterns, which may be parted so as to be 'rammed up' on fallow boards or a level floor, or the patterns may be solid, and have to be bedded, as it is termed; pieces on the top may be made loose, or fastened on so as to 'cope off;' patterns may be well finished so as to draw clean, or rough so that a mould may require a great deal of time to dress up after a pattern is removed.Disintegrating machines, such as are employed for pulverising various substances, grinding grain or pulp, separating fibrous material, and so on, are, with some exceptions, simple enough to be readily understood. One of these exceptions is the rotary "disintegrators," recently introduced, about the action of which some diversity of opinion exists. The effect produced is certainly [60] abrasive wear, the result of the pieces or particles striking one against another, or against the revolving beaters and casing. The novelty of the process is in the augmented effect produced by a high velocity, or, in other words, the rapidity of the blows.
TWO:The villages Gougnies and Biesmes had been destroyed also; of the former not one house was left undamaged; but nothing happened to the townlet Mettet. Here we were forbidden to go on, as we were already more than nine miles and a half from Charleroi. This compelled us to leave the main road, and to proceed along byways which soon took us to the Ardennes, where our motor-car rushed along in zigzags.
