the required spot ; but where there is no such head of water, 
the latter must be provided from a reservoir artificially 
prepared, and kept constantly full 
There are two very simple and cheap modes of effecting 
this, which we shall lay before our readers, and one or the 
other of which may be adopted in almost every locality. 
The first is to provide a large flat cistern of sufficient size, 
which is to be placed under the roof in the upper story of 
one of the outbuildings, the carriage-house for example, 
and receive its supplies from the water collected on the 
roof of the building ; the amount of water collected in this 
way from a roof of moderate size being much more than 
is generally supposed. The second is to sink a well of 
capacious size (where such is not already at command) 
in some part of the grounds where it will not be con- 
spicuous, and over it to erect a small tower, the top of 
which shall contain a cistern and a small horizontal wind- 
mill ; which being kept in motion by the wind more or less 
almost every day in summer, will raise a sufficient quantity 
of water to keep the reservoir supplied from the well 
below. In either of these cases, it is only necessary to 
carry leaden pipes from the cistern (under the surface, 
below the reach of frost) to the place where the jet is to 
issue ; the supply in both these cases will, if properly 
arranged, be more than enough for the consumption of the 
fountain during the hours when it will be necessary for it 
to play, viz. from sunrise to evening. 
The steam-engine is often employed to force up water 
for the supply of fountains in many of the large public and 
royal gardens ; but there are few cases in this country 
where private expenditures of this kind would be justifiable. 
But where a small stream, or even the overflow of a
