either the storage tank must be very large and correspondingly 

 expensive, or the crops run grave risk of going short of water 

 at the time they need it most. There are many suitable engines 

 driven by oil, petrol, gas, hot-air, steam, or electricity, any of 

 which will be found more dependable than an engine driven by 

 wind, and where one of these is used a tank holding 5,000 

 gallons per acre of garden will be found large enough. 



For a garden of two acres the supply pipe from tank to 

 ground should be 4in. in diameter, mains 3in., branches 2in., 

 stand-pipes or hydrants liin., with liin. cocks or taps, and the 

 hose-pipe should be the same size. This arrangement will 

 ensure ample pressure and permit of several hose-pipes being 

 in use simultaneously. The plan below shows the general lines 

 on which a French garden is laid out, with the arrangement of 

 water-pipes.
