In Bath Patrick Alexander set up the first of a series of workshops. His most prestigious workshop was "The Mount" at Batheaston purchased in 1900 and here he had a gas supply brought into the garden and a balloon inflation valve installed. Town gas, although not as light as Hydrogen, was readily available and very much less expensive; it was, of course, highly flammable. His workshops were fully equipped and employed several people, there he designed and manufactured experimental balloons and meteorological instruments.
