Although every farmer round has a right to turn out his beasts, yet the moorman expects a fee for each horse, bullock, or sheep sent out on the downs. Cattle, horses, and sheep sent upon the common lands that adjoin the forest are liable to stray on to the broader expanse, and in order to detect these and exact a fine for them certain drivings are ordered, locally called "drifts." The day when a drift is to take place is kept a profound secret till it is proclaimed early in the morning. Then a messenger on a fleet horse is sent round very early to announce it. On certain tors are holed stones, and through these horns were formerly passed and blown on such occasions. There are drifts for ponies, and drifts for bullocks. A drift is an animated and striking scene. Horsemen and dogs are out, the farmers identifying their cattle, the drivers and dogs sending the frightened beasts plunging, galloping in one direction towards the place of gathering. When all the beasts have been driven together, an officer of the Duchy mounts a stone and reads a formal document that is supposed to authorise the moormen to make their claim for fees. Then the Venville tenants carry off their cattle without objection. All others are pounded, or else their owners pay fines before being allowed to reclaim them. Now and then the Duchy endeavours to extend its right over the commons belonging to contiguous parishes. Nothing is lost by asserting a right, and something may be gained. But when a drift is carried over such commons the farmers of the parishes rise up and repel the moormen, and battles with clubs and horsewhips ensue. Blows are given and returned; it is felt, and felt rightly, that encroachment must be resisted at all cost, lest it should serve as a stepping-stone for deprivation of further rights.
