'They would be thrown all over the shop,' answered Zita. 'That is why I am at Prickwillow. I cannot get away. Jewel could not pull the laden van along the drove; and if other horses were attached to it, everything would be shaken to pieces.'

Presently Jewel came to a halt.

'Shall I jump out and urge him on?' asked Mark.

'No; he is breathing. He will go on again presently.'

'And whilst he is breathing, we will talk. Conversation is impossible when we are bumping into ruts and bouncing over clods. If this be travelling when there is snow half-choking the wheelruts and levelling the clods, what must it be at other times?'

'You see I am a prisoner at Prickwillow. I cannot get away without the loss of all my possessions.'

'I see that now.'

Presently Mark said, 'Zita, why were you on the river with Pip Beamish the other day?'

'I hired him with half a pound of bird's eye to punt me up stream. He behaved unfair; he went off and left me.'
