see on our fir, oak, nut and ash trees, on grasses, spinach, docks and nettles, which are all fertilised through the agency of the wind.

A similar line of argument holds good with fruits; that a ripe strawberry or cherry is as pleasing to the eye as to the palate — that the gaily-coloured fruit of the spindle-wood tree and the scarlet berries of the holly are beautiful objects — will be admitted by everyone. But this beauty serves merely as a guide to birds and beasts, in order that the fruit may be devoured and the matured seeds disseminated. I infer that this is the case from having as yet found no exception to the rule that seeds are always thus disseminated when embedded within a fruit of any kind (that is within a fleshy or pulpy envelope), if it be coloured of any brilliant tint, or rendered conspicuous by being white or black.
