A FOUNTAIN.
if the water requires to be brought from a yet greater distance
the pipes must be of larger diameters.
Unless the bends in pipes of communication from the re-
servoir to the aperture or ajutage be easy and bold, the es-
cape will be proportionally impeded; and to produce an even and
regular jet it is necessary to apply a suitable air-vessel near
to the ajutage, the construction of which is well known to
manufacturers in copper, of which material they are usually
constructed.
The designs are simple in form, and consequently limited in
show of water; but if the jets were amply supplied, the over-
flow of the tables would produce the effect desired.
Designs of this kind are now usually manufactured in artificial
stone, or sculptured in Portland stone; as they were formerly of
lead, the convertibility of which valuable metal undoubtedly
assisted in the rapid disappearance of fountains as soon as they
fell into disrepute. The present rage for cast iron will probably
supercede the use of such leaden works, and as iron would offer
no premium for their demolition, they may be expected to enjoy
a longer triumph of fashionable importance in our gardens.
