FORE:Prout departed on his errand. It was easy enough for him to obtain a private interview with the prisoner, who received him with polite mockery. His instinct told him that Prout wished to learn something.Need I say that I did all I could to make the woman a little more reasonable, and make her understand that it would not do to let a child of ten walk by itself from Lige to Maastricht, and least of all in these dire times. But I could not make her see this, and this instance proves all the more, perhaps, how upset the inhabitants of Lige were that morning; they were nearly out of their senses for fear.

FORE:Leaving out problems of mechanism in forging machines, the adaptation of pressing or percussive processes is governed mainly by the size and consequent inertia of the pieces acted upon. In order to produce a proper effect, that is, to start the particles of a piece throughout its whole depth at each blow, a certain proportion between a hammer and the piece acted upon must be maintained. For heavy forging, this principle has led to the construction of enormous hammers for the performance of such work as no pressing machinery can be made strong enough to execute, although the action of such machinery in other respects would best suit the conditions of the work. The greater share of forging processes may be performed by either blows or compression, and no doubt the latter process is the best in most cases. Yet, as before explained, machinery to act by pressure is much more complicated and expensive than hammers and drops. The tendency in practice is, however, to a more extensive employment of press-forging processes.
