house found it very hard to keep his own house warm, and was astounded
at the amount of coal it took to render his family comfortable, while
the "other fellow" kept himself warm at his neighbor's expense nearly a
whole winter before the trick was discovered.

IMPROVEMENTS IN CONCRETE CONSTRUCTION.


Portland cement concrete if made with a non-porous aggregate is
impervious to moisture, and yet at the same time, if not hydraulically
compressed, will take up a sufficient quantity of moisture from the air
to prevent condensation upon the surface of the walls. It not only
resists the disintegrating influences of the atmosphere, but becomes
even harder with the lapse of time. It may also be made in several
different colors, and can be finished off to nearly a polished surface
or can be left quite rough. Walls built of this material may be made so
hard that a nail cannot be driven into them, or they can be made
sufficiently soft to become a fixing for joinery, and, if a non-porous
aggregate be used, no damp course is required. Further than this, if
land be bought upon which there is sufficient gravel, or even clay that
can be burnt, the greatest portion of the building material may be
obtained in excavating for the cellar; and in seaside localities, if the
(salt) shingle from the beach be used, sound and dry walls will be
obtained. The use of concrete as a material for building will be found
to meet all the defects set forth by practical people, as it may be made
