As has been mentioned previously, the cellar must be well drained,
either by natural or by artificial means. No stagnant water should be
allowed to remain in the cellar, although at the higher temperatures
of the best cellars this does less harm than it does in cellars that
are too cold. Some beekeepers have advocated having a stream of water
flowing through the cellar, and this will do no harm in warm cellars,
and it may serve to assist somewhat in maintaining an even temperature.
