+<p><b>Fire Island Beach</b> is a barrier of sand, stretching for twenty miles
+along the south coast of Long Island, and separating the Great South Bay
+from the Atlantic ocean.
+</p><p>
+To reach it, you must make a sail of from three to seven miles, and once
+upon it, you find it a wild, desolate, solitary spot, wind-searched and
+surf-pounded.
+</p><p>
+Its inner shore is covered with a growth of tide-wet sedge, with here
+and there a spot where dry meadow comes down to make a landing-place.
+</p><p>
+The outline of this inner shore is most irregular, curving and bending
+in and out and back upon itself, making coves and points and creeks and
+channels, and often pushing out in flats with not water enough on them
+at low tide to wet your ankles.
+</p><p>
+A third of the distance across the Beach, the meadow ends and sand
+begins. This slopes gradually up for another third of the distance, to
+the foot of the sand hills, which seem tumbled into their places by some
+mighty power, sometimes three tiers of them deep, sometimes two, and
+sometimes only one.
+</p><p>
+These sand hills are the most striking features of the Beach. The
+biggest of them are not more than sixty feet high, yet so hard a feat is
+it to climb to the top, and so extended is the view below you—on one
+side the wide Bay, on the other, the ocean stretching its restless
+surface to the horizon—that you feel yourself upon an elevation tenfold
+as high.
+</p><p>
+Through these hills the wind makes a great galloping, whirling out deep
+bowl-shape hollows among them, and piling the shifting sand upon their
+summits. Now and then you will notice a hill with its shoulder knocked
+off by the wind, and a ton of sand gone no one can tell where. In every
+storm their contour changes, and yet their general formation is so
+similar at all times that the change is seldom thought of. A coarse
+spear-like grass finds a sparse growth upon them, and does what it can
+to hold the sand in place; but it has a hard time of it, as its blades
+buried to their tips or its naked roots often testify.
+</p><p>
+But there is one part of this Beach that is ever much the same. It is a
+broad, shelving strip of sand between the hills and the sea, where the
+tide rises and falls, pounding and grinding, year in and year out—the
+play-ground and the battle-ground of the surf.
+</p><p>
+On a summer’s day, I have seen this surf so low and quiet that one could
+launch a sharpie upon it, single-handed, and come ashore again without
+shipping a quart of water. At other times it is a terror to look at—a
+steady break of waves upon the outer bar, with row after row coming in,
+rearing and plunging as they strike the shore. In such a sea there is no
+launching yawl or surf-boat, and no coming ashore.
+</p><p>
+When the tide is on the right moon and the wind has blown a gale from
+the southeast, the strand is entirely submerged, and people upon the
+main shore three miles away can see the surf breaking over the Beach
+hills.
+</p><p>
+Such a riot of sea and wind strews the whole extent of beach with
+whatever has been lost or thrown overboard, or torn out of sunken ships.
+Many a man has made a good week’s work in a single day by what he has
+found while walking along the Beach when the surf was down.
+</p><p>
+“The Captain” knew all this and had patrolled that Beach scores of
+times.
+</p><p>
+Ten years had passed since the first time which laid the habit of
+wandering along the surf-shore apparently in search of whatever the sea
+had cast up. Sometimes a spar, sometimes sheets of copper torn from a
+wreck and carried by a high surf far along the strand, sometimes a
+vessel’s gilded name, at other times only scattered drift-wood were the
+rewards of these lonely walks.
