EMBELLISHMENTS. 467 



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 les? 

 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
