THREE:A learner will no doubt wonder why sand is used for moulding, instead of some more adhesive material like clay. If he is not too fastidious for the experiment, and will apply a lump of damp moulding sand to his mouth and blow his breath through the mass, the query will be solved. If it were not for the porous nature of sand-moulds they would be blown to pieces as soon as the hot metal entered them; not only because of the mechanical expansion of the gas, but often from explosion by combustion. Gas jets from moulds, as may be seen at any time when castings are poured, will take fire and burn the same as illuminating gas.The ceremony wound up with a short silent prayer offered at the request of the parson.

TWO:The first of these operations includes all threading processes performed on lathes, whether with a single tool, by dies carried positively by slide rests, or by milling.We are now in a position to understand how far Epicurus was justified in regarding the expectation of immortality as a source of dread rather than of consolation. In this respect also, the survival of the fittest has determined that human92 nature shall not look forward with satisfaction to the termination of its earthly existence. Were any race of men once persuaded that death is the passage to a happier world, it would speedily be replaced by competitors holding a belief better adapted to the conditions of terrestrial duration. Hence, practically speaking, the effect of religious dogmas has been to make death rather more dreaded than it would have been without their aid; and, as already observed, their natural tendency has been powerfully stimulated by the cupidity of their professional expositors. The hope of heaven, to exist at all, must be checked by a considerably stronger apprehension of hell. There is a saying in America that the immortality of the soul is too good to be true. We suspect that the immortality in which most religious Americans still believe hardly deserves such a compliment; but it accurately expresses the incredulity with which a genuine message of salvation would be received by most men; and this explains why Universalism, with the few who have accepted it, is but the transition stage to a total rejection of any life beyond the grave. No doubt, in the first flush of fanaticism, the assurance of an easy admission to paradise may do much to win acceptance for the religion which offers it; but when such a religion ceases to make new conquests, its followers must either modify their convictions, or die out under the competition of others by whom mortal life is not held so cheap.
TWO:Steady, all! Engines quit and left us with a dead stick! No danger.
