For a large house, a tank that will hold about two hun- 
dred gallons will be requisite, and for a smaller housa, 
one in proportion. This tank duing the earlier growing 
season ought to be kept full of water, so that when used 
it may be of the same temperature as the inside of the 
house. Cold water applied immediately from an under- 
ground cistern, or well, suddenly checks the action of ali 
ag and ought by all means to be guarded against 
The force-pump may be attached to the tank, and if an 
air-tight metal globe be fixed over the discharge pipe, on 
the same principle as a fire engine, a steady stream will 
be propelled through the hose. By having two faucets or 
the lower pipes, one leading tothe tank, and the other 
from the cistern below, there is no need for two pumps, as 
they may be shut, and opened, so as to answer the double 
purpose of drawing water from the cistern, or distributing 
it from the tank over the house. For a small grapery 
where eunemy is an object, a common syringe may be 
used instead of the hose, but in a large house the force 
pump is more economical, and has the advantage of ena 
bling the operator to drive the water well into the crevices 
of the ace which greatly assists in keeping clear
