It would be out of place in this treatise to discuss the question into what departments or branches the executive business of government may most conveniently be divided. In this respect the exigencies of different governments are different; and there is little probability that any great mistake will be made in the classification of the duties when men are willing to begin at the beginning, and do not hold themselves bound by the series of accidents which, in an old government like ours, has produced the existing division of the public business. It may be sufficient to say that the classification of functionaries should correspond to that of subjects, and that there should not be several departments independent of one another, to superintend different parts of the same natural whole, as in our own military administration down to a recent period, and in a less degree even at present. Where the object to be attained is single (such as that of having an efficient army), the authority commissioned to attend to it should be single likewise. The entire aggregate of means provided for one end should be under one and the same control and responsibility. If they are divided among independent authorities, the means with each of those authorities become ends, and it is the business of nobody except the head of the government, who has probably no departmental experience, to take care of the real end. The different classes of means are not combined and adapted to one another under the guidance of any leading idea; and while every department pushes forward its own requirements, regardless of those of the rest, the purpose of the work is perpetually sacrificed to the work itself.
