The Encyclopedia of Founding

Twelve hundred entries from the golden age of cast metal — how bells are founded, why brass is not bronze, what a cupola melts and a core withstands — by Simpson Bolland, the trade's great teacher.

Drain

A hole sunk beneath a mould in the pit when there is danger of water accumulating there. A well can be sunk some distance away, into which the water will flow, to be expelled by means of a pump. Cinder-beds may be made to answer as drains by laying them on a slant and providing a well at their lowest point for the water to collect in. See CINDER-BED. Dram is the same as drachm. The avoirdupois dram is equivalent to 27 1/3 1/2 grains troy; the apothecaries' dram is equivalent to 60 grains troy.
