From the boUer are twopipes, one from the middle of the side, the other over it ashigh as it can be placed (in fact ordinary flow and returnpipes), of two-inch gun-baiTel tubing; they are 20 feet inlength, and then join a cistern made ofgalvanised sheet fron to contain about (.; /f^ eight gallons; they have a rise of 9 inchesfrom the boUer to the cistern. The coverof the cistern is moveable but closelyfitted, and there is a small opening in thecover of about 2 inches in diameter fittedwith a loose top, through which the gar-dener supplies the cistern with water as. a, BoUer. 6, Bimsens bnmer. c, c. , d, Ketttrn-pipe.
