The trouble from the French standpoint was that they were advancing squarely towards the mountain ridge that forms the backbone of the Riff sausage and had to fight separately for every little foothill. Nonetheless, the losses apparently were not heavy, and an advance was made several miles deep on a 40-mile front. Thirteen of the blockhouses (the French advance posts before the campaign began...
...Mass., was a mill-hand in a Maine lumber camp. He worked with the night shift and part of his job was to keep the boiler simmering.

When the fire cooled down, Crack! would go the boiler door, back inward, concave like a saucer...
Within the Spencer Thermostat, there will be a little disc of flexible metal. When an iron or percolator gets too hot, crick! will go the disc, convex like a bubble, and cut off the current. When the iron cools, crack! concave like a saucer, and the current will go on again.

...exerted suddenly, considerable resistance is offered even by as mobile a body as air. Birds are enabled to fly only by the resistance of the air during the downward stroke of the wings. During the upward stroke, less resistance is offered, owing to the fact that the wing is convex on the upper side, and is at the same time contracted in area, thus moving with less velocity. In fact instantaneous photographs show that it takes twice the time to complete the upstroke that is needed for the downstroke. Unless matter offered resistance, no force could be brought to bear...
