In endeavouring, however, for a moment to glance back into the unwritten past, and to reconstruct the conditions of some fourteen or fifteen centuries since, it must not be forgotten that the downs may then have presented a different appearance. There is a tradition lingering still that they were in the olden times almost covered with wood. I have tried to fix this tradition--to focus it and give it definite shape; but like a mist visible from a distance yet unseen when you are actually in it, it refuses to be grasped. Still, there it is. The old people say that the king--they have no idea which king--could follow the chase for some forty miles across these hills, through a succession of copses, woods, and straggling covers, forming a great forest. To look now from the top of the rampart over the rolling hills, the idea is difficult to admit at first. They are apparently bare, huge billowy swells of green, with wide hollows, cultivated on the lower levels, but open and unenclosed for mile after mile, almost without hedges, and seemingly treeless save for the gnarled and stunted hawthorns--apparently a bare expanse; but more minute acquaintance leads to different conclusions. Here, to begin with, on the same ridge as the earthwork and not a quarter of a mile distant, is a small clump of wind-harassed trees, growing on the very edge. They are firs and beech, and, though so thoroughly exposed to furious gales, have attained a fair height even in that thin soil. Beech and fir, then, can grow here. Away yonder on another ridge is another such a clump, indistinct from the distance; though there is a pleasant breeze blowing and their boughs must sway to it, they appear motionless. With the exception of the poplar, whose tall top as it slowly bends to the blast describes such an arc as to make its motion visible afar, the most violent wind fails to enable the eye to separate the lines of light coming so nearly parallel from the branches of an elm or an oak, even at a comparatively short distance. The tree looks perfectly still, though you know it must be vibrating to the trunk and loosening the earth with the wrench at its anchoring roots.
