The first thing that we have got to do is to rid our minds of the belief that because we see a supply-carrier lying at anchor for some days without being cleared, more money is being spent than is spent on the maintenance of a shore depot. There may be circumstances in which a secondary base is a necessity, but they must be rare and exceptional. We saw that the establishment of one does not help us in the matter of defending our communications. We now see that, so far from being more economical than the alternative method, the secondary base method is more costly. It might have been demonstrated that it is really much more costly than the figures given make it out to be, because ships obliged to go to a base must expend coal in doing so, and coal costs money. It is not surprising that consideration of the secondary base system should evoke a recollection of the expression applied by Dryden to the militia of his day: In peace a charge; in war a weak defence. I have to say that I did not prepare this paper simply for the pleasure of reading it, or in order to bring before you mere sets of figures and estimates of expense. My object has been to arouse in some of the officers who hear me a determination to devote a portion of their leisure to the consideration of those great problems which must be solved by us if we are to wage war successfully. Many proofs reach me of the ability and zeal with which details of material are investigated by officers in these days. The details referred to are not unimportant in themselves; but the importance of several of them if put together would be incomparably less than that of the great question to which I have tried to direct your attention. The supply of a fleet is of high importance in both peace time and time of war. Even in peace it sometimes causes an admiral to pass a sleepless night. The arrangements which it necessitates are often intricate, and success in completing them occasionally seems far off. The work involved in devising suitable plans is too much like drudgery to be welcome to those who undertake it. All the same it has to be done: and surely no one will care to deny that the fleet which has practised in quiet years the system that must be followed in war will start with a great advantage on its side when it is at last confronted with the stern realities of naval warfare. POSTSCRIPT The question of 'Communications,' if fully dealt with in the foregoing paper, would have made it so long that its hearers might have been tired out before its end was reached. The following summary of the points that might have been enlarged upon, had time allowed, may interest many officers:-- In time of war we must keep open our lines of communication. If we cannot, the war will have gone against us. Open communications mean that we can prevent the enemy from carrying out decisive and sustained operations against them and along their line.
