William Crossing (1847–1928) was a writer and chronicler of Dartmoor and the lives of its inhabitants. He lived successively at South Brent, Brentor and at Mary Tavy but died at Plymouth, Devon. Early life Crossing was born in Plymouth on 14 November 1847. Early in his youth he was fond of Dartmoor, his early associations centring on the south-west of the moor, in the neighbourhood of Sheepstor, Walkhampton, Meavy, and Yannadon. He acquired a taste for antiquities from his mother. He later went on to explore Tavistock, Coryton, Lydford, Okehampton, and the northern borders of Dartmoor, as well as South Brent, on its southern verge. After finishing his schooling in Plymouth, he went to the Independent College at Taunton, and then returned to finish his education at the Mannamead School (later called Plymouth College). His earliest literary efforts were in fiction: "thrilling romances", composed for the delectation of his schoolfellows. His first essay in poetry was at the age of fourteen, when a poem of his appeared in the pages of Young England, December 1861. In 1863 he went for a short coastal voyage to Wales, and gained a liking for the sea; in 1864 he joined a vessel bound for Canada, and had a narrow escape, nearly being crushed by an iceberg during the night. Returning from this voyage, he took to business pursuits in Plymouth, and then recommenced his Dartmoor explorations. Later life and writings In 1872 he married and settled down at South Brent. In 1871 he had begun making notes about his rambles, but without any systematic arrangement; after his marriage he seems to have become more methodical, and to have decided to write a book descriptive of the moorland district. He published numerous other works in the 1890s, and his Guide to Dartmoor, illustrated by Philip Guy Stevens, in 1909. He was much afflicted by rheumatism in the last 25 years of his life, and in 1921 his wife died. From July 1925 to his death Crossing was an invalid. He died at Plymouth, 3 September 1928. He is now considered one of the best authorities on Dartmoor and its antiquities, having made it the subject of his life's work. He was one of the earliest members of the Dartmoor Preservation Association, joining it immediately on its formation. It is quite probable that he effectively started the popularity of the modern pursuit of letterboxing. In
