In the Duchy records appear various well-known names that one does not naturally associate with the Forest. The Conqueror granted it to his half-brother, Robert, Earl of Montaigne; King John gave the Earldom of Cornwall to his second son, Richard Plantagenet, afterwards King of the Romans. This Prince 'much augmented the powers of the stannaries of Devon and Cornwall, and under his auspices they thrived exceedingly.' For a short time the earldom was bestowed on Piers Gaveston; Thomas Cromwell and some others had a lease of the lead-mines on the moor for twenty-one years; the first Earl of Bedford was 'Custos of the Forest or Chase of Dartmoor'; and Sir Walter Raleigh was appointed Ranger and Master Forester, besides being Lord Warden of the Stannaries. The first perambulation of the forest boundaries probably took place in 1224, and others have been made at intervals ever since; yet a long tale of grievances from that date almost up to the present time might be heard from commoners whose rights have been encroached upon. The bounds of property owned by religious houses at certain points were marked by granite crosses, of which a great number are still to be found on the moor. Some of them, however, were standing long before the monasteries were built. To take one instance, the cross on Sourton Down has an inscription which, it has been declared, belongs to the sixth century, and which can still be deciphered when the sun is setting and the rays slant across it. The Abbot's Way, leading over the moor, is marked by crosses. It ran westwards from Buckfast Abbey, and divided at Broad Rock, near Plym Head, in the middle of the moor--one branch going to Tavistock, and the other to Buckland Abbey. The path cannot now be traced the whole way, but the crosses show the line. Beckamoor Cross (or the Windy Post, as it is sometimes called), between two and three miles south-east of Tavistock, is a typical Dartmoor cross, and a fine example, but it cannot be numbered among the very old ones, for it seems to date from the sixteenth century.
