The cuckoo is a bird that figures largely in English poetry, but he always has an equivocal look in American verse, unless sharply discriminated. We have a cuckoo, but he is a great recluse; and I am sure the poets do not know when he comes or goes, while to make him sing familiarly like the British species, as I have known at least one of our poets to do, is to come very wide of the mark. Our bird is as solitary and joyless as the most veritable anchorite. He contributes nothing to the melody or the gayety of the season. He is, indeed, known in some sections as the rain- crow," but I presume that not one person in ten of those who spend their lives in the country has ever seen or heard him. He is like the showy orchis, or the lady's-slipper, or the shooting star among plants,— a stranger to all but the few; and when an American poet says cuckoo, he must say it with such specifications as to leave no doubt what cuckoo he means, as Lowell does in his "Nightingale in the Study:"—
"And, hark, the cuckoo, weatherwise,
Still hiding farther onward, wooes
you."
In like manner the primrose is an exotic in American poetry, to say nothing of the snowdrop and the daisy. Its prominence in English poetry can be understood when we remember that the plant is so abundant in England as to be almost a weed, and that it comes early and is very pretty. Cowslip and oxlip are familiar names of varieties of the same plant, and they bear so close a resemblance that it is hard to tell them apart. Hence Tennyson, in "The Talking Oak:"—
"As cowslip unto oxlip is,
So seems she to the boy."
Our familiar primrose is the evening primrose,—a rank, tall weed that blooms with the mullein in late summer. Its small, yellow, slightly fragrant blossoms open only at night, but remain open during the next day. By cowslip, our poets and writers generally mean the yellow marsh marigold, which belongs to a different family of plants, but which, as a spring token and a pretty flower, is a very good substitute for the cowslip. Our real cowslip, the shooting star, is very rare, and is one of the most beautiful of native flowers. I believe it is not found north of Pennsylvania. I have found it in a single locality in the District of Columbia, and the day is memorable upon which I first saw its cluster of pink flowers, with their recurved petals cleaving the air. I do not know that it has ever been mentioned in poetry.
Another flower, which I suspect our poets see largely through the medium of English literature and invest with borrowed charms, is the violet. The violet is a much more winsome and poetic flower in England than it is in this country, for the reason that it comes very early and is sweet-scented; our common violet is not among the earliest flowers, and it is odorless. It affects sunny slopes, like the English flower; yet Shakespeare never could have made the allusion to it which he makes to his own species in these lines:—
"That strain again! it had a dying fall:
Oh! it came o'er my ear like the sweet south
That breathes upon a bank of violets,
Stealing and giving odor,"
or lauded it as
"Sweeter than the lids of Juno's eyes,
Or Cytherea's breath."
Our best known sweet-scented violet is a small, white, lilac-veined species (not yellow, as Bryant has it in his poem), that is common in wet, out-of-the-way places. Our common blue violet—the only species that is found abundantly everywhere in the North—blooms in May, and makes bright many a grassy meadow slope and sunny nook. Yet, for all that, it does not awaken the emotion in one that the earlier and more delicate spring flowers do,—the hepatica, say, with its shy wood habits, its pure, infantile expression, and at times its delicate perfume; or the houstonia,—"innocence,"— flecking or streaking the cold spring earth with a milky way of minute stars; or the trailing arbutus, sweeter scented than the English violet, and outvying in tints Cytherea's or any other blooming goddess's cheek. Yet these flowers have no classical associations, and are consequently far less often upon the lips of our poets than the violet.
