AS general rule, IL may De lalQ down


that there is no auxiliary so powerful in


diminishing the amount of such moisture


as cannot be actually shut out from any


part OF building, as free circulation OF


air. 1t is to be remembered that the at


mosphere is almost always in such state


that when it comes into contact with free


moisture it will absorb some of it. Let,


therefore, openings communicating with


be freely provided. The hollow space in a


and the hollow under floor, should all


enjoy free circulation of air. 1t is even


desirable, in building hollow walls, to at


the cavity, and in oil these cases it should


be remembered that two openings are re-


quisite to each hollow in order to give


much hope of current or change of air


Where there is no ventilation under the


lowest floor of a house, the joists and


timbers will soon begin to decay. This


may be accelerated by covering the floor


with oil cloth or kamptulicon or similar


non-porous coverings. Ivy or creepers


against external walls, and even trees


growing close to them, tend to promote


moisture by cutting off circulation of air.


The failure Of any portion Of the ar


rangements for water-supply or drainage


will be pretty sure to lead to damp. As
general rules, no drain should ever be


permitted to pass under any part Of a
dwelling house and when this cannot be
prevented, the drain should be so laid
without being covered up with earth, that
every part fit which is under the floor of
the house can be reached at once. The
water pipes, on the other hand, should be
kept we'll within the house for warmth's
sake, and, where they leave it, should be
at level of not less than three feet at the
least below the surface, for protection
against frost. Whenever practicable,
water pipes should be left where they can
be seen and got at. Iron Is preferable to
lead for their material, and the arrange
mcnts should always include the mta of
shutting off water supplies in very frosty
weather


1t only remains to suggest to those per-
sons who unfortunately find themselves in
damp house which they cannot leave,
that they ought to use as many remedies as
they can, rather than only one at time;
that, as far as possible, what is done should
be done in dry weather. and that the re-
pairs or remedies attempted should be car
ried out with good materials and labor,
in the most thorough way possible, and
under vigilant supervision. Damp is
most insidious, fluids it's way in at very
small and very out-of-the-way inlets, and
when once established seems very 10th to
be disturbed. Those who build for them
selves will, we hope, not overlook the
very just importance Of the simple precau-
tions necessary to keep their houses dry;
but we should be especially gratitied if
these observations induce some of our
readers who rent houses to bestow some
little pains in ascertaining, before they
take a house, if these precautions have
to select a wet day for looking over
house, for if the day be fine, and the
weather dry, damp spots as we'll as many
other defects may be easily overlooked
Let the intending tenant look for the ex-
listing Of damp courses, dry areas, and ven
tilation under floors; let him avoid
ground floor that is not little raised
above the earth outside, unless he is sure
there is good cavity under it we'll venti-
lated. Bricks that are manifestly porous,
or which change color very much when
rain falls, parapets with no copings, walls
where the pointing is not thoroughly
sound, caves without cutters, and the like,
are to be looked upon with great distrust
and an unsound roof or ill.arranged gut.
ttrs (of which, Blythe bye, few non pro-
persons can form a good opinion)
ought to be looked upon with as much
disfavor as dining room of the wrong
shape, or drawing room that looks
gloomy. In one word, in choosing house
in which man intends himself and his
family to live, he should look out for the
indications of damp as pointing out the
presence of one of the most serious enc
mics to his comfort, if not to the continu-
ance of their life, which he can have to
encounter. Tool Journal.
