There is a sort of {geography of religion ; and I regret to think that tlie majority of mankind take their creed from the dime in whidi they happen to be bom ; and that many, and not an inconsider- able portion of mankind, suffer the sacred torch to bum out altogether, in their contact with the world, and then vainljr imagine that they can recover the sacred fire by striking a spark out of dogmatic theology I

��ADOmON TO THE CHiJmB on RAILB0AD&

One of the most important fietcts which the engine-driver ought to know is the exact time since the preceding train has passed the point of railroad on which his own engine is.

This may be done by placing signals, about to be described, by the side of or across the road at all places where such know- ledge is most important.

The principle to be employed is, that at the passage of those places the engine itself should, in its transit, wind up a weight or spring. That this weight should act upon an arm standing perpendicularly, which would immediately commence moving slowly to the horizontal position. This it should attain by an equable motion at the end of three, five, or any desirable number of minutes.

The means of raising the weight may be derived either from a projection below the engine or by one above it. The latter, which seems preferable, might be attached to a light beam tra- versing the road to which the apparatus should be fixed.
