It was principally with flowers, which excite more attention and give more pleasure than most natural objects, that my mind was occupied in this connection; for here it seemed to me that the effect was similar to that produced on the mind by sweet human-like tones in bird music. In other words, a very great if not the principal charm of the flower was to be traced to the human associations of its colouring; and this was, in some cases, more than all its other attractions, including beauty of form, purity and brilliance of colour, and the harmonious arrangement of colours; and, finally, fragrance, where such a quality existed.

We see, then, that there is an intimate connection between the two subjects—human associations in the colouring of flowers and in the voices of birds; and that in both cases this association constitutes, or is a principal element in, the expression. This connection, and the fact that the present subject was suggested and appeared almost an inevitable outcome of the one last discussed, must be my excuse for introducing a chapter on flowers in a book on birds—or birds and man. But an excuse is hardly needed. It must strike most readers that a great fault of books on birds is, that there is too much about birds in them, consequently that a chapter about something else, which has not exactly been dragged in, may come as a positive relief.

As the word expression which occurs with frequency in this chapter was not understood in the sense in which I used it on the first appearance of the book, it may be well to explain that it is not used here in its ordinary meaning as the quality in a face, or picture, or any work of art, which indicates thought or feeling. Here the word has the meaning given to it by writers on the æsthetic sense as descriptive of the quality imparted to an object by its associations. These may be untraceable: we may not be conscious and as a rule we are not conscious that any such associations exist; nevertheless they are in us all the time, and with what they add to an object may enhance and even double its intrinsic beauty and charm.

I have somewhere read a very ancient legend, which tells that man was originally made of many materials, and that at the last a bunch of wild flowers was gathered and thrown into the mixture to give colour to his eyes. It is a pretty story, but might have been better told, since it is certain that flowers which have delicate and beautiful flesh-tints are attractive mainly on that account, just as blue and some purples delight us chiefly because of their associations with the human iris. The skin, too, needed some beautiful colour, and there were red as well as blue flowers in the bunch; and the red flowers being most abundant in nature and in greater variety of tints, give us altogether more pleasure than their beautiful rivals in our affection.

The blue flower is associated, consciously or not, with the human blue eye; and as the floral blue is in all or nearly all instances pure and beautiful, it is like the most beautiful human eye. This association, and not the colour itself, strikes me as the true cause of the superior attraction which the blue flower has for most of us. Apart from association blue is less attractive than red, orange, and yellow, because less luminous; furthermore green is the least effective background for such a colour as blue in so small an object as a flower; and, as a fact, we see that at a little distance the blue of the flower is absorbed and disappears in the surrounding green, while reds and yellows keep their splendour. Nevertheless the blue has a stronger hold on our affections. As a human colour, blue comes first in a blue-eyed race because it is the colour of the most important feature, and, we may say, of the very soul in man.

Some purple flowers stand next in our regard on account of their nearness in colour to the pure blue. The wild hyacinth, blue-bottle, violet, and pansy, and some others, will occur to every one. These are the purple flowers in which blue predominates, and on that account have the same expression as the blue. The purples in which red predominates are akin in expression to the reds, and are associated with flesh-tints and blood. And here it may be noted that the blue and blue-purple flowers, which have the greatest charm for us, are those in which not only the colour of the eye but some resemblance in their form to the iris, with its central spot representing the pupil, appears. For example, the flax, borage, blue geranium, periwinkle, forget-me-not, speedwell, pansy and blue pimpernel, are actually more to us than some larger and handsomer blue flowers, such as the blue-bottle, vipers' bugloss, and succory, and of blue flowers seen in masses.

With regard to the numerous blue and purple-blue flowers which we all admire, or rather for which we all feel so great an affection, we find that in many cases their very names have been suggested by their human associations—by their expression.

Love-in-a-mist, angels' eyes, forget-me-not, and heartsease, are familiar examples. Heartsease and pansy both strike us as peculiarly appropriate to one of our commonest and most universal garden flowers; yet we see something besides the sympathetic and restful expression which suggested these names in this flower—a certain suggestion of demureness, in fact, reminding those who have seen Guido's picture of the "Adoration of the Virgin," of one of his loveliest angels whose angelical eyes and face reveal some desire for admiration and love in the spectator. And that expression, too, of the pansy named Love-in-Idleness, has been described, coarsely or rudely it may be, in some of its country names: "Kiss me behind the garden gate," and, better (or worse) still, "Meet-her-i'-th'-entry-kiss-her-i'-th'-buttery." Of this order of names are None-so-pretty and Pretty maids, Pretty Betsy, Kiss-me-quick. Even such a name as Tears of the blood of Christ does not sound extravagantly fanciful or startling when we look at the glowing deep golden crimson of the wall flower; nor of a blue flower, the germander speedwell, such names as The more I see you the more I love you, and Angels' tears, and Tears of Christ, with many more.

A writer on our wild flowers, in speaking of their vernacular names of this kind, has said: "Could we penetrate to the original suggestive idea that called forth its name, it would bring valuable information about the first openings of the human mind towards nature; and the merest dream of such a discovery invests with a strange charm the words that could tell, if we could understand, so much of the forgotten infancy of the human race."
