always kept to the same level, need not be above six inches ; 

 but, as it is seldom practicable to keep the head to the same 

 level, it is better to have the bottom of the pond or cistern 

 sufficiently high to effect the desired object ; in which case, 

 so long as there is any water in the cistern at all, the jet will 

 rise to the proper height. 



Where a natural head of water of the proper height cannot 

 be obtained, recourse may be had to artificial means of raising 

 water to an elevated cistern or reservoir. This cistern may 

 either be placed on a natural or artificial eminence, or on 

 the summit of a building. In pleasure-grounds, an artificial 

 mount, or piece of conical rockwork, would afford a good 

 situation; and a simple tower, round or square, is also at 

 once a cheap mode of elevating a cistern, and of adding to 

 grounds an ornament, which, if not very beautiful, can yet 

 never be considered mean or paltry. 



The water may be raised to the basin or cistern so placed, 

 by forcing-pumps worked by men, horses, wind, water, or 

 steam; or by that very ingenious machine, the hydraulic ram, 

 which we have before noticed (Vol. V. p. 594-.) as being in 

 use at Bury Hill ; and which has lately been put up, in various 

 parts of the country, for this purpose, by Mr. Rowley. How- 

 ever, the mode which we would recommend, as most directly 

 applicable where there is no natural power, is that of having 

 a small steam-engine, say of two-horse power, which might 

 be placed in the lower part of the tower containing the cistern, 

 or in any convenient situation near the well, pond, or other
