In 1847 Ballantyne returned to Scotland to discover that his father had died. He published his first book the following year, ''Hudson's Bay: or, Life in the Wilds of North America'', and for some time was employed by the publishers
Messrs Constable. In 1856, he gave up business to focus on his literary career, and began the series of adventure stories for the young with which his name is popularly associated.
The Young Fur-Traders (1856),
The Coral Island (1857),
The World of Ice (1859),
Ungava: a Tale of Eskimo Land (1857),
The Dog Crusoe (1860),
The Lighthouse (1865),
Fighting the Whales (1866),
Deep Down (1868),
The Pirate City (1874),
Erling the Bold (1869),
The Settler and the Savage (1877), and more than 100 other books followed in regular succession, his rule being to write as far as possible from personal knowledge of the scenes he described.
The Gorilla Hunters. A tale of the wilds of Africa (1861) shares three characters with
The Coral Island: Jack Martin, Ralph Rover and Peterkin Gay. Here Ballantyne relied factually on
Paul du Chaillu's
Exploration in Equatorial Guinea, which had appeared early in the same year.
The Coral Island is the most popular of the Ballantyne novels still read and remembered today, but because of one mistake he made in that book, in which he gave an incorrect thickness of coconut shells, he subsequently attempted to gain first-hand knowledge of his subject matter. For instance, he spent some time living with the lighthouse keepers at the
Bell Rock before writing
The Lighthouse, and while researching for
Deep Down he spent time with the
tin miners of
Cornwall. In 1857–58, Ballantyne wrote several nursery tales under the pseudonym 'Comus', including
Three Little Kittens (1857),
My Mother (1857), ''The Butterfly's Ball and the Grasshopper's Feast
(1857), Mister Fox
(1857), and The Robber Kitten
(1858). They were printed by Thomas Nelson and Sons in illustrated editions with verse versions (in the case of The Butterfly's Ball
by William Roscoe and My Mother'' by
Ann Taylor) and musical arrangements for piano and for a duet with a child. In 1866 Ballantyne married Jane Grant, with whom he had three sons and three daughters. ==Later life and death==
