commodore's log - View this location on map 'Tilghman Island itself has no manor houses, but it's fast becoming a place for vacationers. Long a working-class community centered around farming and the sea harvest, it lost many of its watermen when the oyster harvest crashed. The old Tilghman can still be seen in the island's venerable skipjacks  the large sailboats, that are generally the only boats allowed to dredge for oysters in the bay  based in Dogwood Harbor. Documenting the island's past and present is Gary D. Crawford, above, who with his wife, Susan, owns and operates Crawfords Nautical Books (on the right about a mile beyond the bridge, 410-886-2418; www.crawfordsnautical.com). The shop, in a former bank building, has 11,000 or so books, from Mr. Crawford's own works about Tilghman ($5 to $10) to a first edition of Commodore Matthew C. Perry's account of his 1850's trade mission to Japan ($3,400). . '' New York Times 5782 Main Street, Tilghman, MD Shopping,
