The light is never the same on a landscape many minutes together, as all know who have tried, ever so crudely, to fix the fleeting expression of the earth with pencil. It is ever changing, and in the same way as you walk by the hedges day by day there is always some fresh circumstance of nature, the interest of which in a measure blots out the past. This morning we found a bramble leaf, something about which has for the moment put the record of months aside. This bramble leaf was marked with a grey streak, which coiled and turned and ran along beside the midrib, forming a sort of thoughtless design, a design without an idea. The Greek fret seems to our eyes in its regularity and its repetition to have a human thought in it. The coils and turns upon this leaf, like many other markings of nature, form a designless design, the idea of which is not traceable back to a mind. They are the work of a leaf-boring larva which has eaten its way between the two skins of the leaf, much like boring a tunnel between the two surfaces of a sheet of paper. If you take a needle you can insert the point in the burrow and pass it along wherever the bore is straight, so that the needle lies between the to sides of the leaf. Off-hand, if any one were asked if it were possible to split a leaf, he would say no. This little creature, however, has worked along inside it, and lived there. The upper surface of the leaf is a darker green, and seems to the touch of firmer texture than the lower; there are no marks on the under surface, which does not seem touched, so that what the creature has really done is to split one surface. He has eaten along underneath it, raising it no doubt a little by the thickness of his body, as if you crept between the carpet and the floor. The softer under surface representing the floor is untouched. The woodbine leaves are often bored like this, and seem to have patterns traced upon them. There is no particle of matter so small but that it seems to have a living thing working at it and resolving it into still more minute atoms; nothing so insignificant but that upon examination it will be found to be of the utmost value to something alive. Upon almost every fir branch near the end there are little fragments like cotton, so thick in places as to quite hang the boughs with threads; these gossamer-like fragments appear to be left by some insect, perhaps an aphis; and it is curious to note how very very busy the little willow-wrens are in the fir boughs. They are constantly at work there; they sing in the firs in the earliest spring, they stay there all the summer, and now that the edge of autumn approaches their tiny beaks are still picking up insects the whole day long. The insects they devour must be as numerous as the fir needles that lie inches thick on the ground in the copse.
