The seam has a bad roof, and the Henderson stand is beingused with the machines to great advantage. Example XIV. (Durham).—Three machines have been inuse for more than a year. Each machine is controlled by alad, 17 or 18 years old, with a younger boy, 14 or 15 years old,who is occupied chiefly in scraping out the cuttings. The machine is mounted on a small-wheeled iron tram,running on the ordinary tub tramway, and standing only a fewinches in height (Fig. 7); and by means of iron plates, coveringthe foot of the upright column, and bolts, the machine is fastened REPORT OF COMMITTEE UPON MECHANICAL COAL-CUTTI \( I 69 firmly to the tram. When it is run into the face, the only workrequired, in fixing it, is to run out the screw of the column bythe ratchet-brace, until it bears tightly against a timber-plankplaced next the roof, and to steady the tram against the outwardthrust by placing a wood chock under it.
