are wastefully dispersed by the winds to one which
reaches a female flower and fertilizes a seed.
Contrast this with one of the close-fertilized flowers
of a violet, in which there are not many times more
grains of pollen produced than there are of seeds
to be fertilized; or with an orchis-flower, in which
the proportion is not widely different. These
latter are certainly the more economical; but there
is reason to believe that the former arrangement is
not wasteful. The plan in the violet-flower assures
the result with the greatest possible saving of material
and action; but this result, being close-fertilization
or breeding in and in, would, without much doubt,
in the course of time, defeat the very object of having
seeds at all.[XIII-3] So the same plant produces other
flowers also, provided with a large surplus of pollen,
and endowed (as the others are not) with color, fragrance,
and nectar, attractive to certain insects, which are
thereby induced to convey this pollen from blossom
to blossom, that it may fulfill its office. In
such blossoms, and in the great majority of flowers,
the fertilization and consequent perpetuity of which
are committed to insects, the likelihood that much
pollen may be left behind or lost in the transit is
sufficient reason for the apparent superfluity.
So, too, the greater economy in orchis-flowers is
accounted for by the fact that the pollen is packed
in coherent masses, all attached to a common stalk,
the end of which is expanded into a sort of button,
with a glutinous adhesive face (like a bit of sticking-plaster),
and this is placed exactly where the head of a moth
or butterfly will be pressed against it when it sucks
nectar from the flower, and so the pollen will be
bodily conveyed from blossom to blossom, with small
chance of waste or loss. The floral world is full
of such contrivances; and while they exist the doctrine
of purpose or final cause is not likely to die out.
Now, in the contrasted case, that of pine-trees, the
vast superabundance of pollen would be sheer waste
if the intention was to fertilize the seeds of the
same tree, or if there were any provision for insect-carriage;
but with wide-breeding as the end, and the wind which
“bloweth where it listeth” as the means,
no one is entitled to declare that pine-pollen is
in wasteful excess. The cheapness of wind-carriage
may be set against the overproduction of pollen.
Similar considerations may apply to the mould-fungi
and other very low organisms, with spores dispersed
through the air in countless myriads, but of which
only an infinitesimal portion find opportunity for
development. The myriads perish. The exceptional
one, falling into a fit medium, is imagined by the
Westminster Reviewer to argue design from the beneficial
provision it finds itself enjoying, in happy ignorance
of the perishing or latent multitude. But, in
view of the large and important part they play (as
the producers of all fermentation and as the omnipresent
scavenger-police of Nature), no good ground appears
for arguing either wasteful excess or absence of design
from the vast disparity between their potential and
their actual numbers. The reserve and the active
members of the force should both be counted in, ready
as they always and everywhere are for service.
Considering their ubiquity, persistent vitality, and
promptitude of action upon fitting occasion, the suggestion
would rather be that, while
