Schacht[180] observes: "In wooded countries, the atmosphere is generally
humid, and rain and dew fertilize the soil. As the lightning rod
abstracts the electric fluid from the stormy sky, so the forest attracts
to itself the rain from the clouds, which, in falling, refreshes not it
alone, but extends its benefits to the neighboring fields. * * The
forest, presenting a considerable surface for evaporation, gives to its
own soil and to all the adjacent ground an abundant and enlivening dew.
There falls, it is true, less dew on a tall and thick wood than on the
surrounding meadows, which, being more highly heated during the day by
the influence of insolation, cool with greater rapidity by radiation.
But it must be remarked, that this increased deposition of dew on the
neighboring fields is partly due to the forests themselves; for the
dense, saturated strata of air which hover over the woods descend in
cool, calm evenings, like clouds, to the valley, and in the morning,
beads of dew sparkle on the leaves of the grass and the flowers of the
field. Forests, in a word, exert, in the interior of continents, an
influence like that of the sea on the climate of islands and of coasts:
both water the soil and thereby insure its fertility." In a note upon
this passage, quoting as authority the _Historia de la Conquista de las
siete islas de Gran Canaria, de Juan de Abreu Galindo_, 1632, p. 47, he
adds: "Old historians relate that a celebrated laurel in Ferro formerly
furnished drinkable water to the inhabitants of the island. The water
flowed from its foliage, uninterruptedly, drop by drop, and was
collected in cisterns. Every morning the sea breeze drove a cloud toward
the wonderful tree, which attracted it to its huge top," where it was
condensed to a liquid form.
In a number of the _Missionary Herald_, published at Boston, the date of
which I have mislaid, the Rev. Mr. Van Lennep, well known as a competent
observer, gives the following remarkable account of a similar fact
witnessed by him in an excursion to the east of Tocat in Asia Minor:
