The smugglers, warned by Coppinger, had crept up the path in silence, and singly, at considerable intervals between each, and on reaching the summit of the cliffs had dispersed to their own homes, using the precaution to strike inland first, over the "new-take" wall.

As the last of the party reached the top he encountered one of the coast-guards, who, by the orders of his superior, was patrolling the down to watch that the smugglers did not leave the cove by any other path than the one known -- that up and down which donkeys were driven. This donkey-driving to the beach was not pursued solely for the sake of contraband; the beasts brought up loads of sand, which the farmers professed they found valuable as manure on their stiff soil, and also the masses of seaweed cast on the strand after a gale, and which was considered to be possessed of rare fertilizing qualities.
