ON THE THERMAL
can be placed in any generalisation from these South American
mean temperatures.
The question is probably considered too simply — too much
to the neglect of concurrent influences. Until we know, for
example, somewhat more of the comparative radiant powers of
different soils, we cannot expect any very definite result. A
change of temperature would certainly be effected by the
plantation of such a marshy district as the Sologne, because, if
nothing else were done, the roots might pierce the impenetrable
subsoil, allow the surface-water to drain itself off, and thus dry
the country. But might not the change be quite different if
the soil planted were a shifting sand, which, fixed by the roots
of the trees, would become gradually covered with a vegetable
earth, and thus be changed from dry to wet ? Again, the
complication and conflict of effects arises, not only from the
soil, vegetation, and geographical position of the place of the
experiment itself, but from the distribution of similar or
different conditions in its immediate neighbourhood, and
probably to great distances on every side. A forest, for
example, as we know from Herr Rivoli's comparison, would
exercise a perfectly different influence in a cold country subject
to warm winds, and in a warm country subject to cold winds;
so that our question might meet with different solutions even
on the east and west coasts of Great Britain.
The consideration of such a complexity points more and more
to the plantation of Malta as an occasion of special importance;
its insular position and the unity of its geological structure
both tend to simplify the question. There are certain points
about the existing climate, moreover, which seem specially
calculated to throw the influence of woods into a strong relief.
Thus, during four summer months, there is practically no
rainfall. Thus, again, the northerly winds when stormy, and
especially in winter, tend to depress the temperature very
suddenly; and thus, too, the southerly and south-westerly
winds, which raise the temperature during their prevalence to
