Thirty-Five Logbooks & the Dennis Wood Abstracts

American whaling logbooks · 1844–1877

Thirty-five manuscript logbooks, read page by page and transcribed word for word: 33,820 days at sea, each in the keeper’s own words, with his position as he wrote it and a link to the page itself. Fifty-one voyages, thirty-three years. Read the days yourself: Every entry in the corpus. Pick a voyage, choose what happened, or search the keepers’ own words, spelling and all. Open a day to read it as he wrote it, line for line, then follow the link to the manuscript page and check our reading against his hand.

The Dennis Wood Abstracts of Whaling Voyages

The logbooks say where a ship was. Dennis Wood, a New Bedford merchant, kept the other half of the record: four ledgers in which, from 1831 to 1876, he abstracted every whaling voyage the port could learn of: sailing, master, agent, each report that came home by letter or newspaper or a ship spoken at sea, the oil sent ahead, the arrival and the cargo “turned out.” The four volumes, held by the New Bedford Free Public Library and scanned on the Internet Archive, were read page by page in September 2026: 2,552 pages, 7,980 voyage entries (7,158 voyages once entries carried across pages are joined), 79,955 dated reports. Every entry in the four volumes, by vessel. Pick a ship to read what Wood wrote about each of her voyages (heading, reports and arrival), with the volume and page to check the scan.

What the lookouts saw

Every species had a name from the masthead: polar whales (bowheads), right whales, California greys and devil fish, sperm whales, finbacks, blackfish, grampus. The logs record where each was found, chased, struck, and lost. In the quiet stretches they record what else lived out there: walrus on the ice, goneys astern, terrapin taken at the Galápagos.

The ice record

Whaling logs are among the only instruments that measured the 19th-century Arctic: dated positions with ice in sight, freeze-up and break-up, gales given hour by hour. This corpus holds 1,767 ice days (the Okhotsk Sea in June, the Chukchi edge in September, a winter frozen into Repulse Bay) and the eyewitness record of the days before the great fleet disaster of September 1871, when thirty-three ships were abandoned to the ice off Point Belcher.

The human record

Fires and mutinies, cholera quarantines, a boy lost at Tahiti, an Arctic explorer coming aboard for tea, four hundred and fifty emigrants carried from Hong Kong to California. Some of these events survive in two logs at once, told from both decks.

How far to trust it

Every reading was made by an AI reader looking at an image of the manuscript, and AI readers make mistakes. We detail the checks that have been run, and what each one found.
