"The Bell Buoy" is a poem by Rudyard Kipling. It was first published with illustrations in Saturday Review, Christmas Supplement 1896 and then published in McClure's Magazine in February 1897 as "The Bell-Buoy", with illustrations by Oliver Herford.
Some changes to the wording occurred sometime between the edition in McClure's and when it was collected in Rudyard Kipling's verse: inclusive edition, 1885-1918 (1919) as "The Bell Buoy". The other changes are minor and some may be the correction of printing errors.
