[To the Editor of the SPECTATOR.]

Sin,—The letter by " Parallax commenting upon Com- mander Windham's advocacy of the spending of money on roads and air service in preference to a Channel Tunnel omits, I think, to give sufficient weight to the question of transhipment, &c., costs. Perhaps more often than not such costs provide the major part' of transit costs. Goods will only " flow " to this or that weight-carrier provided the cost of doing so does not overbalance that of the cheaper method of weight-carrying. In other words, the method of transport is governed by the sum total of costs, not by the portage costs alone. It seems reasonable to argue rather that no method of transport should be developed at the expense of another, for there is need for each according to circumstances.—I am, Sir, &c., W. J. G.
