What is our problem to-day? It is again the problem of power and movement; not a new problem, but a very old problem, in fact the eternal problem dressed up in a new frock. Our problem is to revive our old industries, so far as they can be revived, and to establish new ones, for industries, like the human beings who create them, grow old, come on the pension list and die. Our problem is, as it was during the war, to shift the population, to demobilize our great army of unemployed, and to cause it to trickle from our over-populated little island into our underpopulated Dominions and Colonies. Lastly, our problem is to secure ourselves against another war. To-day, we find ourselves in a veritable labyrinth of difficulties, but there must be a way out, possibly several, for otherwise we could not be standing in its centre. We have got into it, so we can get out of it, as we have of many a former maze; but how? It is here that I think the spirit of George Stephenson can help us, and it is for this reason that I have taken up so much of this little book with this great man’s name and work, and with the difficulties he faced and, undaunted, conquered. His motto was “Perseverance”; let it be ours. He did not talk over much, but he took his coat off and got to work. He worked single-handed and was obstructed at every turn. The whole country was against him, yet he conquered, and, more to him than to any other man a century ago, it seems to me, were the problems, which then faced England, solved, and they are the problems which face England now. As it may be said, and with some truth, in fact a great deal of truth, that the railway made the war, since it made the peace which preceded the war, so with equal truth may it be said that the petrol engine, encased in a tank, by making peace possible, may now make peace profitable, even if in doing so it begets the germs of another war. In other words, as the war was so largely won by the tank, so must the peace which has followed it be largely won by the caterpillar tractor, or roadless vehicle. Henry Herbert will vote me to Bedlam, but this is the most encouraging fact of all, for every new idea must start by being in a minority of one, such as that of George Stephenson’s against the world. The stronger the opposition the better the idea, may not be a law of Nature, yet it is a pretty sound rule, and one with few exceptions. If we persevere and laugh, the caterpillar tractor will win the peace, and to paraphrase the words of George Stephenson, I will, in my turn, make a prophecy:
