motive force, in the place of petroleum, in the motor which his eldest
son had so long been trying to construct for the Grandidier works. So he
had set to work with Thomas, devising a new mechanism, encountering
endless difficulties, and labouring for a whole year before reaching
success. But now the father and son had accomplished their task; the
