the dip of a hasty short flight

After he had cooled he arose and made his way back to a pleasant hardwood forest of maple and beech. Here the leaves were just bursting from their buds. Underfoot the early spring flowers--the hepaticas, the anemones, the trilium, the dog-tooth violets, the quaint, early, bright-green undergrowths--were just reaching their perfection. Migration was in full tide. Birds, little and big, flashed into view and out again, busy in the mystery of their northward pilgrimage, giving the appearance of secret and silent furtiveness, yet each uttering his characteristic call from time to time, as though for a signal to others of the host. The woods were swarming as city streets, yet to Orde these little creatures were as though invisible. He stood in the middle of a great multitude, he felt himself under the observation of many bright eyes, he heard the murmuring and twittering that proclaimed a throng, he sensed an onward movement that flowed slowly but steadily toward the pole; nevertheless, a flash of wings, a fluttering little body, the dip of a hasty short flight, represented the visible tokens. Across the pale silver sun of April their shadows flickered, and with them flickered the tracery of new leaves and the delicacy of the lace-like upper branches.
Orde walked slowly farther and farther into the forest, lost in an enjoyment which he could not have defined accurately, but which was so integral a portion of his nature that it had drawn him from the banks and wholesale groceries to the woods. After a while he sat down on a log and lit his pipe. Ahead the ground sloped upward. Dimly through the half-fronds of the early season he could make out the yellow of sands and the deep complementary blue of the sky above them. He knew the Lake to lie just beyond. With the thought he arose. A few moments later he stood on top the hill, gazing out over the blue waters.
Very blue they were, with a contrasting snowy white fringe of waves breaking gently as far up the coast as the eye could reach. The beach, on these tideless waters, was hard and smooth only in the narrow strip over which ran the wash of the low surf. All the rest of the expanse of sand back to the cliff-like hills lay dry and tumbled into hummocks and drifts, from which projected here a sawlog cast inland from a raft by some long-past storm, there a slab, again a ship's rib sticking gaunt and defiant from the shifting, restless medium that would smother it. And just beyond the edge of the hard sand, following the long curves of the wash, lay a dark, narrow line of bark fragments.
