In 1874 the Central Authority expressed its regret at the slow progress "towards the permanent classification in separate establishments of the various classes of indoor paupers, other than the sick.... We attach the utmost importance to this improvement of the classification of indoor paupers, which we believe to be a necessary condition of the maintenance of that discipline which lies at the root of an effective administration of indoor relief. This improvement, however, cannot be effected, except at an enormous and almost prohibitory cost, otherwise than by the combination of several boards of guardians for this purpose. Their existing workhouses would, in that event, become available for the separate accommodation of various classes of indoor paupers chargeable to the several combined areas. We are advised that in the existing state of the law it is doubtful whether such a combination can be effected otherwise than by the voluntary action of boards of guardians, which we trust may still take place, and the desirableness of which we shall continue to press upon the guardians."[789] No such combinations took place, and the Central Authority, baffled by the expense and apparently not prepared to adopt the heroic expedient of issuing orders merging several unions in one, abandoned the attempt to get classification by institutions, except with regard to the children and the sick. The able-bodied had to be dealt with in a general workhouse; and we must note, for twenty years after 1871, battling with the ameliorative efforts of the departmental architect, the departmental medical officer, and the departmental educational experts, on behalf of particular classes of inmates, an attempt to make the workhouse more "deterrent" to other classes of paupers.

The most marked increase of severity was directed against the class of "ins and outs," called in America "revolvers," and it took the form of enlarged powers of detention. By an Act of 1871 the guardians were enabled to detain a pauper (other than a vagrant) who gave notice to quit, in any case for twenty-four hours; if he had already discharged himself once or oftener within a month before giving the notice, for forty-eight hours; and if he had so discharged himself more than twice within two months, for seventy-two hours.[790] Under the Act of 1899[791] a pauper may even be compulsorily detained for 168 hours (one week) "if he has, in the opinion of the guardians, discharged himself frequently without sufficient reason."
