The first requisite of a good servant is that he should conspicuously know his place. It is not enough that he knows how to effect certain desired mechanical results; he must above all, know how to effect these results in due form. Domestic service might be said to be a spiritual rather than a mechanical function. Gradually there grows up an elaborate system of good form, specifically regulating the manner in which this vicarious leisure of the servant class is to be performed. Any departure from these canons of form is to be depreciated, not so much because it evinces a shortcoming in mechanical efficiency, or even that it shows an absence of the servile attitude and temperament, but because, in the last analysis, it shows the absence of special training. Special training in personal service costs time and effort, and where it is obviously present in a high degree, it argues that the servant who possesses it, neither is nor has been habitually engaged in any productive occupation. It is prima facie evidence of a vicarious leisure extending far back in the past. So that trained service has utility, not only as gratifying the master's instinctive liking for good and skilful workmanship and his propensity for conspicuous dominance over those whose lives are subservient to his own, but it has utility also as putting in evidence a much larger consumption of human service than would be shown by the mere present conspicuous leisure performed by an untrained person. It is a serious grievance if a gentleman's butler or footman performs his duties about his master's table or carriage in such unformed style as to suggest that his habitual occupation may be ploughing or sheepherding. Such bungling work would imply inability on the master's part to procure the service of specially trained servants; that is to say, it would imply inability to pay for the consumption of time, effort, and instruction required to fit a trained servant for special service under the exacting code of forms. If the performance of the servant argues lack of means on the part of his master, it defeats its chief substantial end; for the chief use of servants is the evidence they afford of the master's ability to pay.
