Salt deposition is studied on the cliffs of the Lizard and Land's End Peninsulas, and the following conclusions are drawn. (1) The salt deposited is almost the same in ionic composition as sea-water. (2) The quantity of salt deposited is closely correlated with the frequency of winds greater than 14 m s-1. (3) The quantity of salt deposited falls off very rapidly in the first 500 m inland from the sea and little reduction occurs after 2 km. (4) As predicted, the vegetation type of the cliff appears to be correlated with the quantity of salt deposited. (5) The soil is in equilibrium with salt deposition, and deposition appears to equal loss by rainwash.
