One thing, however, may be said by way of preliminary to the account of this particular tour. There was much controversy at the beginning of 1905 upon the question whether the movement of a six-cylinder petrol car is, or is not, more luxurious than that of a four-cylinder car of first-rate design and construction. A prolonged match, not entirely free from flukes, the bane of motoring trials, has been held by way of attempt to decide the issue; and it has ended in favour of six cylinders, as illustrated by the identical car in which this tour was taken. The controversy will probably go on for ever, none the less, for it is the old case of _de gustibus_ which can never be settled, and it is all but impossible to compare memories of kindred sensations felt at different times. Who can say, for example, which cigar, glass of old wine, sail on a strong breeze, gallop over the Downs, run in a first-rate motor-car, dive into cool water, which--almost what you will, so long as it be one of the pleasures classified by old Aristotle as coming into being through the touch--was absolutely the best of his life? Without scientific certainty, however, there may be strong conviction, and mine is that a good six-cylinder, whether Rolls-Royce or Napier, runs more smoothly than any four-cylinder car, and I have tried nearly all the best of them. In fact, there is very little to choose in point of smooth running, if indeed there be anything to choose at all, between it and a White steam car, used on another East Anglian tour. Tried by the, to me, infallible touchstone of my own spine, a six-cylinder is a very little, but still distinctly, more luxurious than the best four-cylinder car; but this is not to say that there are not a round dozen of four-cylinder cars on the market which make their passengers as comfortable as any man, or even delicate woman, can reasonably wish to be in this world.
