It may seem absurd to include Barnacles among plants; but in the time of Shakespeare the Barnacle tree was firmly believed in, and Gerard gives a plate of "the Goose tree, Barnacle tree, or the tree bearing Geese," and says that he declares "what our eies have seene, and our hands have touched."

A full account of the fable will be found in Harting's "Ornithology of Shakespeare," p. 247, and an excellent account in Lee's "Sea Fables Explained" (Fisheries Exhibition handbooks), p. 98. But neither of these writers have quoted the testimony of Sir John Mandeville, which is, however, well worth notice. When he was told in "Caldilhe" of a tree that bore "a lytylle Best in Flessche in Bon and Blode as though it were a lytylle Lomb, withouten Wolle," he did not refuse to believe them, for he says, "I tolde hem of als gret a marveylle to hem that is amonges us; and that was of the Bernakes. For I tolde hem, that in our Contree weren Trees, that beren a Fruyt, that becomen Briddes fleeynge; and tho that fallen in the Water lyven, and thei that fallen on the Erthe dyen anon; and thei ben right gode to mannes mete. And here of had thei als gret marvaylle that sume of hem trowed, it were an impossible thing to be" ("Voiage and Travaille," c. xxvi.).
