Looking westward from the island at high tide this morning you could see already deep hints of this coming autumn coloring, swelling out of the deep green of grasses that make up the main carpeting of the marsh, touches of brown and olive that are singularly pleasing to the eye under the summer blue of the sky and its fleecy flecking of white clouds. Amid these, scattered here and there, round eye-like pools reflect this summer blue and fleecy whiteness and all along the island's verge and that of other islands and the borders of the Glades was the pink of wild roses and morning glories, both of which seem to thrive better and bloom later in the season here than inland. But the softest and loveliest coloring that the marsh will ever get is that which the gray mists of early morning seem to have brought in and left like a fragrant memory of themselves, the lavender gray of the marsh-rosemary. "There's rosemary; that's for remembrance," said Ophelia, and many a lover of sea and marsh-side will carry longest in memory the gentle sadness that the tint of the sea-lavender gives the marsh when all its other colors are still those of the flush joy of summer. Remembering Ophelia, marsh-rosemary seems its best name, though you have a right to sea-lavender if you wish. If the sea fogs did not bring it as an essence of the first glimpse of dawn in gray ocean spaces, then I am convinced that the loving tides bear it as a gift to the island and scatter it shyly at its feet, after dark.

You have but to wander about the shores of the island at the marsh line to find strange evidence of this gift-bearing propensity of the shy tides. Trinkets of all sorts that they gather in travels in distant seas the tides bring and lay lovingly at the roots of black oak and sweet gum, hickory and stag-horn sumac. Here is bamboo that for all I know grew near the head waters of the Orinoco, though it may have sprouted in the Bahamas, floated north by the Gulf Stream, shunted from its warm edge into the chill of the Labrador current and drawn thence by the Cohasset tides. Beside this lies a cask ripped from the deck of a Gloucester fishing schooner that sought the halibut even on the chill banks that lie just south of the point of Greenland. And so they come, chips from a Maine shipyard, wreckage from a Bermuda reef, and a thousand tiny things picked up at points between.

But the tides bring to the marsh and the island in it, to all shores that they touch here on our Atlantic seaboard, more than this. They bear deep in their emerald hearts, generated in their cool, clear depths, a rich vivific principle that bears vigor to all that they touch and sends rich emanations forth on the air beyond. Today on the inland hills and land-bound pastures the sun beat in sullen insolence and the wind from the west scorched and wilted the life in all things. The same wind, coming to me across two miles of salt marsh, had in its cool, salty aroma a life-giving principle that set the pulse to bounding and renewed vigor. It had gathered up from the marsh this tonic of the tides, this elixir vitae which all the doctors of the world have sought in vain. Some day some one of them, wiser than the rest, will distil its potency from the cool salt of sea tides, and humanity, poor hitherto, will find itself rich in possibilities of physical immortality. Sea captains have a foolish custom of settling down at eighty to enjoy life on shore, else there is no knowing how long they would live. They have breathed the aroma of this life-giving essence all their lives.

Yet the sea itself is dead; it is a vast accumulation of the product of complete combustion, hydrogen burnt out. But just as dead worlds, which are the molecules of infinite space, shocking together, burst into spiral nebulae of flame which are the beginnings of live suns and planets and all luxuriant life thereon, so it seems as if the atoms of sea water, ever rushing to restless collision, burst continually into renewed life. All forms are in it, from the mightiest mammals to the protozoa which the microscope suspects rather than surely discovers. Every time molecule touches molecule in the depths, a new spark of tiny life must flare up, else never so many could inhabit the water. The coarser aggregations of these we see in bewildering profusion and variety every time the tides fall back and leave the rocks bare. At the bottom of the ebb I like to climb perilously down the rough Glades cliffs to life-brooding pools and inlets, where lazy waves swirl or are for a brief hour cut off. At the half-tide line the rock that is a reddish granite becomes chalky white with the shells of barnacles that cover every inch of space from there down. Acorn-like, they cluster closer than ever acorns did on the most prolific oak. After the tides reach them as they rise, the whole surface of the rock must be fuzzy with their curved cirri of tongues which protrude and lap the rising waves. Their number is legion, yet how infinite must be the fine floating life, so fine that we cannot note that it clouds the limpid water, on which these sessile gray creatures feed.

Below a certain level these are crowded out by the mussels which grow in such dense accumulations that they cling not only to the rock but to one another and to stubby brown seaweed till they are like nothing so much as pods of bees swarming about their queen. So dense is this grouping of living creatures that the inner ones are smothered by their crowding fellows and serve merely as a foundation on which these build. Even among these swarm starfishes and limpets and other crustaceans, and streamers of kelp squirm out from the rock where they keep slender hold, to sway in the restless water, just as all the rocks above a certain depth and below a certain height are olive black with dense hangings of rockweed while in depths that are just awash at low tide they are olive brown with unending mats of Irish moss. These are but the forms of overwhelming life that meet the eye on first descending into the cool depths. To name all that may be noted in just the pause of a single ebb would be to become a catalogue.

Along the Salt Marsh

Yet howsoever vivid the life or astounding by its multiplicity it is not impressions of these that linger long after one has come up from the bottom of the ebb. It is rather that here one has breathed the air of the deep life laboratory of the world, that into his lungs and pores and all through his marrow has thrilled a breath of that subtle essence, that life renewing principle which Fernando de Soto sought in the fountain of youth which he thought bubbled from Florida sands but which in reality foamed beneath his furrowing keel as he ploughed the sea in search of it. It is the same thrill which the wilting west wind steeps from the salt marsh as it comes across, some baffling and alluring ether distilled from under-sea caverns where cool green mermen tend emerald fires. The scent of it levitates from the wash of every wave and if you will watch with pure eyes and clear sight you may of moonlight nights see white-bodied mermaids flashing through the combers to drink of it. No wonder these are immortal.

Nor can you take from the things of the sea this life-giving essence, once they have attained it through growth during immersion in its depths, though perchance, as Emerson sang, "they left their beauty on the shore, with the sun and the sand and the wild uproar." The shell on the mantel shelf of the mariner's inland home may be unsightly and out of place. But put your ear to it. Out of the common noises of the day, it weaves for you the song of the deep tides, the murmur of ocean caves and the croon of the breakers on the outer reef, and dull indeed is your inner ear if you cannot hear these things, and at the sound see the perfect curl of green waves and smell that cool fragrance which comes only from their breaking.
