Henry David Thoreau made several journeys to Cape Cod between eighteen forty-nine and eighteen fifty-five, walking along the wild Atlantic shore and the more sheltered Bay side. He observed the stark landscape of the Cape, where shifting sands, harsh winds, and relentless breakers shape an environment uniquely removed from the inland world. Throughout his walks, he encountered the ruins of shipwrecks, such as the tragic loss of the brig Saint John at Cohasset, which brought waves of Irish emigrants to a sudden and violent end. Thoreau reflected on the callous indifference of the sea and the sober duty of the locals who scavenged the wreckage and reclaimed valuable timber and manure from the tide.
The narrative follows Thoreau as he conversed with local characters, including an eighty-eight-year-old oysterman in Wellfleet who remembered the Revolutionary War and lived entirely by his own hard-won common sense. Thoreau examined the peculiar flora and fauna of the sand plains, detailing dwarf apple trees and poverty-grass that miraculously survived the salt spray and barren earth. He described the vast salt-works, the ancient windmills that served as landmarks for sailors, and the lonely Charity-houses erected by the Humane Society to shelter shipwrecked mariners who managed to scale the steep clay cliffs.
Moving northward toward the sandy hook of Provincetown, Thoreau noted the immense mackerel fleet that crowded the horizon, numbering hundreds of vessels that sailed out from Cape ports to harvest the sea. He detailed the mechanics of blackfish drives, where fishermen herded schools of small whales ashore to harvest their oil. The book closes by meditating on the vastness and inhuman sincerity of the ocean, which remains a timeless wilderness indifferent to human endeavor, washing the shores of continents and consuming the works of men.
