"One of the best things about the American Naval Officer--and one that stands him in good stead at the present time--is his open-mindedness. He may have come over here firmly believing that some gun, some explosive, some system of loading or fire-control, or any of a number of other things he has perfected to the best of his experience, is better than anything else of the kind that Britain or any other nation has got. But that does not blind him in the least to the good points of the latter, and no false sentiment, pride, or conservatism will prevent the incontinent scrapping of his own long-laboured-over invention to make way for what his open mind and sterling common sense tell him is better. It is this which makes it comparatively easy for the American to do a thing which is above almost all others difficult for the Briton--to profit and take advantage of another's experience. "An American destroyer--and the same will be true of any other ships of whatever class that may be sent over--takes its place as a unit of one of our fleets or squadrons just as easily and naturally as if a new British ship, manned by British sailors, had been commissioned, and that will go on just as long as it is necessary or advisable to increase your naval strength in European waters. Indeed, the effective smoothness of the system under which the American ships work with ours makes one feel that--quite without realising it--we have taken the first step in the formation of what has so long been talked of as a Utopian dream--an 'International Police Force.' It is hardly the time to talk of such a consummation at this stage of things; but if it ever does eventuate, you make take it that an Anglo-Saxon naval force will be its foundation." Because it has been impossible to tell the public really anything about American naval co-operation with the British, the historic significance of that event has been almost overlooked. As a matter of fact, however, it marks the first occasion in which the ships of one Allied nation have been practically incorporated (so far as the direction of operations are concerned) in the navy of another. Allied fleets have carried out operations together--as the French and the British at the Dardanelles, or the British and the Italians in the Adriatic--but never has the co-operation been so intimate--and, it may be added, so successful--as in the present instance.
