The author has attempted to construct a plant embodying these
essentials, and the working drawing and photographs shown will give the
reader a tolerable idea of his "Mark V" model.
The thing has, at the moment of writing, only been experimentally tested
in one of the London parks. These trials were, however, sufficiently
satisfactory to encourage a belief that the new plant will prove a very
considerable improvement on the old. It has now been despatched to a
site in Surrey, there to undergo the searching and very practical test
of being used for the building of a small-holder's house and homestead.
