Further experiments appear also to be necessary in order to determine the adhesion of the driving wheel upon wood under various circumstances. It has been represented as much more than upon iron. In a dry state this is very probable; but in a perfectly wet state it is doubtful whether it will not be considerably less, and if so, the supposed advantage of being able to ascend steeper acclivities on the wooden rail may cause disappointments against which it is very material to guard. The same expedient, however, which has been beneficially adopted in the iron rail in a wet state, that of sanding, may prove to be equally or more efficacious on wood. In the meantime there appears to be no sufficient reason to discourage a reliance upon the wooden rail under ordinary circumstances, if abundant breadth be given to the rims of the iron wheels. In the breadth of the wood a liberality can be observed, which in the use of iron is restrained to a minimum by its costliness. In closing these imperfect observations, it may be proper, with regard to the general recommendations which they convey of wooden foundations for railways, to remark that it is not pretended that they can always obviate expensive cuttings and embankments, which must in some instance of necessity be encountered.
