Bideh soils are more productive than such as are
light coored, when in other respects they are equal

TON Jhey rapidly absorb heat when exposed to
Inc rays OF the sun, and as rapidly cool when they
are Withdrawn. Both of these effects are highly
benehch to vegetation. The heat which the soil
acquires during the day, stimulates the action of
the roofs and growth of the plants and the rapid
coollhg OF the surface causes the dew with which
the ar charged TO be deposited early, and in large
quantities. during the evening. Some gardeners
use white sand on the top of the Soils because"
as they say, 1T is so heating" Had they knowl-

they would at once see the absurdty of the prac-

white or very light coored earth can never be fer

colored when growing, and their color helps their
growth in two ways-and for the same reason that
dark soils do, viz by conducting the heat into the
plant While the sun is up, and again conducting it
OIL when down, by which there is a rapid and plen-
tiful deposit of dew upon it.
White buildings reflect the suns rays. while
darker coors absorb them; consequently, those
whlch are white are vastly more durable than such
as are very dark. IL would be more economical 10
