She had taken off her hat, and thrown it down upon the cloak beside her. "It's so oppressively warm in here," she said.

It was not oppressively warm—not warmer than a June night at the North. But the air was perfectly still, and so sweet that it was enervating.

The forest grew denser along this third lane as they advanced. The trees stood nearer together, and silver moss now began to hang down in long, filmy veils, thicker and thicker, from all the branches. Mixed with the moss, vines showed themselves in strange convolutions, they went up out of sight; in girth they were as large as small trees; they appeared to have not a leaf, but to be dry, naked, chocolate-brown growths, twisting themselves about hither and thither for their own entertainment.

This was the appearance below. But above, there was another story to tell; for here were interminable flat beds of broad green leaves, spread out over the outside of the roof of foliage—leaves that belonged to these same naked coiling growths below; the vines had found themselves obliged to climb to the very top in order to get a ray of sunshine for their greenery.

For there was no sky for anybody in the Monnlungs; the deep solid roof of interlocked branches stretched miles long, miles wide, like a close tight cover, over the entire place. The general light of day came filtering through, dyed with much green, quenched into blackness at the ends of the vistas; but actual sunbeams never came, never gleamed, year in year out, across the clear darkness of the broad water floor.

The water on this floor was always pellucid; whether it was the deep current of the main channel, or the shallower tide that stood motionless over all the rest of the expanse, no where was there the least appearance of mud; the lake and the streams, red-brown in hue, were as clear as so much fine wine; the tree trunks rose cleanly from this transparent tide, their huge roots could be seen coiling on the bottom much as the great vines coiled in the air above. These gray-white bald cypresses had a monumental aspect, like the columns of a Gothic cathedral, as they rose, erect and branchless, disappearing above in the mist of the moss. The moss presently began to take on an additional witchery by becoming decked with flowers; up to a certain height these flowers had their roots in the earth; but above these were other blossoms—air-plants, some vividly tinted, flaring, and gaping, others so small and so flat on the moss that they were like the embroidered flowers on lace, only they were done in colors.

"I detest this moss," said Margaret, as it grew thicker and thicker, so that there was nothing to be seen but the silver webs; "I feel strangled in it,—suffocated."

"Oh, but it's beautiful," said Winthrop. "Don't you see the colors it takes on? Gray, then silver, then almost pink as we pass; then gray and ghostly again."

For all answer she called her husband's name. She had called it in this way at intervals ever since they entered the swamp.

"The light we carry penetrates much farther than your voice," Winthrop remarked.
