The workshops are supplied with mechanics by a simple expedient; hopeless specimens of English malefactors, condemned to penal servitude for the term of their natural life, are relegated to this region, a kind of grim humour characterising the selection.

The most hideous convicts are chosen, and those most corresponding in outward appearance to the favourite devils of the hierarchy, under whose names they pass in the workshops, where they commonly communicate with each other in the language of Volapuk.

The reason given is that this language has been adopted by the Spoeleic Rite, which I confess that I had not heard of previously, but I venture to think that the doctor has concealed the true reason, and that Volapuk has been thus chosen because it is a diabolical invention; a universal language prevailed previously to the confusion of Babel, and the new language is an irreligious attempt to produce _ordo ab chao_ by a return to unity of speech.
