‘O, my Lord Duke, have mercy, and don’t stab me!’ cried the shepherd, falling on his knees.  ’I have never seen you walking here, or riding here, or lying-in-wait for a man, or dragging a heavy load!’

‘H’m!’ said his interrogator, grimly, relaxing his hold.  ’It is well to know that you have never seen those things.  Now, which would you rather—­see me do those things now, or keep a secret all your life?’

‘Keep a secret, my Lord Duke!’

‘Sure you are able?’

‘O, your Grace, try me!’

‘Very well.  And now, how do you like sheep-keeping?’

’Not at all.  ’Tis lonely work for them that think of spirits, and I’m badly used.’

’I believe you.  You are too young for it.  I must do something to make you more comfortable.  You shall change this smock-frock for a real cloth jacket, and your thick boots for polished shoes.  And you shall be taught what you have never yet heard of; and be put to school, and have bats and balls for the holidays, and be made a man of.  But you must never say you have been a shepherd boy, and watched on the hills at night, for shepherd boys are not liked in good company.

‘Trust me, my Lord Duke.’

’The very moment you forget yourself, and speak of your shepherd days—­this year, next year, in school, out of school, or riding in your carriage twenty years hence—­at that moment my help will be withdrawn, and smash down you come to shepherding forthwith.  You have parents, I think you say?’

‘A widowed mother only, my Lord Duke.’

’I’ll provide for her, and make a comfortable woman of her, until you speak of—­what?’

‘Of my shepherd days, and what I saw here.’

‘Good.  If you do speak of it?’

‘Smash down she comes to widowing forthwith!’

‘That’s well—­very well.  But it’s not enough.  Come here.’  He took the boy across to the trilithon, and made him kneel down.

‘Now, this was once a holy place,’ resumed the Duke.  ’An altar stood here, erected to a venerable family of gods, who were known and talked of long before the God we know now.  So that an oath sworn here is doubly an oath.  Say this after me:  “May all the host above—­angels and archangels, and principalities and powers—­punish me; may I be tormented wherever I am—­in the house or in the garden, in the fields or in the roads, in church or in chapel, at home or abroad, on land or at sea; may I be afflicted in eating and in drinking, in growing up and in growing old, in living and dying, inwardly and outwardly, and for always, if I ever speak of my life as a shepherd boy, or of what I have seen done on this Marlbury Down.  So be it, and so let it be.  Amen and amen.”  Now kiss the stone.’

The trembling boy repeated the words, and kissed the stone, as desired.

The Duke led him off by the hand.  That night the junior shepherd slept in Shakeforest Towers, and the next day he was sent away for tuition to a remote village.  Thence he went to a preparatory establishment, and in due course to a public school.
