Iisr the economy of rail-roads it is of the greatest importance to consider the nature and effect of the different species of power that are likely to .be applied on them. We shall commence with that which is most simple in its application and certain in its effect; how long it may maintain this rank is questionable, but at present there is not a superior agent for producing motion on a rail-way. Horse Power. When the power of a horse is to be applied to move carriages on a rail-road, it is obvious that we should endeavour to apply it in such a manner as will afford the greatest quantity of useful effect, withas much speed as can be obtained, without injury to the animal. Hence, we have two objects of inquiry; these are, the duration of a day's work, and the maximum of useful effect. Duration of the Day's Work of a Horse.
