A trio of authors from the independent Tilbury House Publishers of Gardiner will sign their books Saturday, April 23 from noon to 3 p.m. at Beyond the Sea Gallery-Café, 74 Main St.

W. H. (Bill) Bunting’s “Live Yankees: The Sewalls and Their Ships” is the story of a Bath family with a broad reach in the world through shipbuilding, managing shipping, investing in railroads and politics. Despite a veneer of old-fashioned formalized civility, international shipping in the late 1800s and early 1900s was a highly competitive, low-margin and often cutthroat business.

While the Sewalls’ shrewd responses to market changes make a fascinating story, the surviving correspondence from their captains offers adventure of another kind. They were required to make regular reports to the Sewall office and this correspondence is a treasure-trove of stories about the voyages of Sewall ships — surly crews, mutinies, plagues, shipwrecks, “cannibal isles,” destitute widows and more, along with details of ship performance, weather encountered, trouble in port and even lawsuits.

Bunting of Whitefield also is the author of “Portrait of a Port: Boston 1852–1914”; “Steamers, Schooners, Cutters, and Sloops”; “A Day’s Work: A Sampler of Historic Maine Photographs, 1860–1920” in two volumes; “Sea Struck”; and “The Camera’s Coast.” With Earle G. Shettleworth, Jr., he was co-author of “An Eye for the Coast: The Maritime and Monhegan Island Photographs of Eric Hudson.”

Eva Murray’s “Well out to Sea: Year-Round on Matinicus Island” explores what is like to live on an island 22 miles out to sea. When she took a job on Matinicus Island in 1987, Murray expected to stay a year as the island’s kindergarten-through-eighth-grade teacher. When the school year ended, she turned down her graduate school acceptance, remained on Matinicus and, in 1989, married the island electrician. She and her husband Paul raised their two children on Matinicus and continue to live and work there full-time.

Murray is a wilderness emergency medical technician, operates a small bakery, has served in several positions of municipal government and has been a regular columnist for local publications since 2003 including Maine Boats, Homes & Harbors, Down East Online and Working Waterfront. She is a 1985 graduate of Bates College and is working on a book about the modern-day one-room schools of Maine. A 30-year resident of Maine with Maine native family, she apologizes for the faux pas of having been born out of state.

Franklin Burroughs is the author of “Confluence: Merrymeeting Bay.” There are said to be only four places in the world where two major rivers — with entirely separate watersheds — converge at their mouths to form a common delta. Three are famous, having loomed large in the histories and economies of their regions — the Sacramento-San Joaquin delta in California, Tigris-Euphrates delta in Iraq and the Ganges-Brahmaputra delta in Bangladesh. The fourth is Merrymeeting Bay in Maine, unfamiliar to most people even within its immediate vicinity.

Burroughs has lived and knocked around on Merrymeeting Bay for three decades, gaining a familiarity with its natural and human history — its birds, fish, and mammals; and the local people who know it best. His wonderfully fluid essays explore the ecology, environment and activities in this unusual bay, and Heather Perry’s beautiful photographs reveal the details.

Burroughs taught English literature at Bowdoin College from 1968 to 2002. He is the author of two other books, “The River Home: A Return to the Low Country” and “Billy Watson’s Croker Sack.” His essays have appeared in a variety of literary quarterlies and have been reprinted in such collections as “Best American Essays,” “The Pushcart Anthology” and “The Norton Anthology of Nature Writing.”
