We rise at length and walk along the wooded slope admiring new beauties at every step. Here is a thicket of wild gooseberry filled with dark green leaves and the tinkling notes of tree sparrows, and we hardly know which is the more beautiful. A little farther and we are in a tangle of pink and magenta raspberry vines from which the green leaves are just pushing out. The elder has made a great start; the yellowish-green shoots from the stems and from the roots are already more than six inches long. The panicled dogwood and the red-osier dogwood (no, not the flowering dogwood) as yet show no signs of foliage, but the fine white lines in the bark of the bladdernut, which have been so attractive all winter, are now enhanced by the soft myrtle green of the tender young leaves. The shrubby red cedar is twice as fresh and green as it was a month ago, as it hangs down the face of the splintered rock where the farmer boys have set a trap to catch the mother mink. But Mrs. Mink is wary. Here is a pile of feathers, evidently from a wild duck, which seems to indicate that while the duck was making a meal of a fish which she had brought to shore, the mink pounced upon her and ate both duck and fish.
While we stand looking there is a slight movement among the roots of a silver maple at the river’s brink. A moment later Mrs. Mink comes around the tree and towards us. She is about eighteen inches long, with a bushy tail about another eight inches, her blackish-brown body about as big round as a big man’s wrist, and she has a “business-looking” face and jaw. Did you ever try to take the young minks from their nest in the latter part of April and did Mrs. Mink fight? She hasn’t seen or smelled us yet, but suddenly when she is within seven feet of us, there is an upward movement of that supple, snakelike neck, a quick glance of those black diamond eyes, and she turns at right angles and dives into the river. A frog could not enter the water so silently.
We climb the slope again and pause in front of a big sugar maple, a rather rare sight hereabouts. The sap-sucker has bored a row of fresh holes in the bark of the tree and the syrup has flowed out so freely that the whole south side of the tree is wet with it. Scores of wasps, bees and flies of all sizes and colors are revelling in the sweetness.
Finally we come to where there is less grass but more dead leaves and leaf mould, and here is the first real herbaceous flower of this spring, the dwarf white trillium, or wake-robin. How beautiful it looks, its three pure, waxy-white petals, its six golden anthers and three long styles, and its pretty whorl of three ovate leaves, at the summit of a stem about four inches high. A little farther and we find a group of them and then other clusters, fresh and pure and sweet enough to make a bouquet for Euphrosyne.
Oh, but someone says, the hepatica is the first flower of spring; all the nature writers say so. Well, but they don’t seem to say much about the trillium; possibly they haven’t found it so often. Indeed, it seems to be more choice of its location. It is hardly ever, perhaps it would be safe to say never, found on a southern or a southwestern slope. Almost invariably it is found on the steep slope of a river bank, facing northeast or east. Hepaticas nearly always grow on the same slope, but they come into blossom about two days later than the trillium. But on another bank which faces the noon and the afternoon sun the hepaticas are up with the trilliums in the calendar of spring. This year the trillium was found blooming, on a northeastern slope, March 24. At this place the hepatica did not bloom until March 26. But it bloomed March 24, on a southwest slope, fifteen miles away.
By-the-way, the list of March blooming plants for 1908, is probably one of the longest for years: March 20, aspen; twenty-first, hazel and silver maple; twenty-third, pussy willow, prairie willow and white elm; twenty-fourth, dwarf white trillium and hepatica (also known as liverleaf, squirrelcup, and blue anemone); twenty-fifth, slippery elm, cottonwood; twenty-ninth, box elder and fragrant sumac; thirtieth, dandelion; thirty-first, Dutchman’s breeches.
How some of these early flowers secure the perpetuation of their species is an interesting study for amateur botanists. In the case of the trillium the fruit is a three-lobed reddish berry, but one has to search for it as diligently as Diogenes did for an honest man before he finds it. The plant seldom sets seed in this vicinity, but seems to depend rather upon its tuber-like rootstocks in which the leaves lie curled all through the winter. The hepatica attracts pollen-feeding flies, female hive-bees and the earliest butterflies, and is thus cross-fertilized to some extent; but it is thought also to be able to effect self-fertilization. In the case of the hepatica acutiloba, however, it has been found that staminate flowers grow on one plant and pistillate flowers on another, hence insects are essential to the perpetuation of this species.
After bringing us the trilliums and hepaticas in numbers, Nature pauses. She means to give us time to inhale the fragrance of some of the hepaticas, and to learn that other hepaticas of the same species have no fragrance at all; that there is a variety of delicate colors, white, pink, purple, lavender, and blue; that the colored parts, which look like petals are really sepals; that they usually number six, but may be as many as twelve; that there are three small sessile leaves forming an involucre directly under the flower; that if we search we shall find some with four, more rare than four-leaved clovers; that the plant which was fragrant last year will also be fragrant this year; that the furry stems are slightly pungent,—enough to give spice to a sandwich; these preliminary observations fit us for more intricate problems later on.
