Morning air, particularly in January, is hungry air; and to wait, with the food under your very nose, and not be free to eat it, is not easy.
"I really must go back a little way to see if they are anywhere near," said Kitty at last, growing impatient and hungry.

Anna and Tony were hungry too, but they were too comfortable and lazy to move, so they leaned luxuriously amongst the dry twigs and leaves and dead grass in the hedge, and watched Kitty as she walked eagerly back again along the level road they had just travelled.

When she reached the brow of the hill she stopped, and the next moment a peal of laughter announced the fact that she had caught sight of the laggards.
It was unkind, perhaps, of her to laugh.

Dan thought it was "beastly mean," but then he was not in a frame of mind to see the humour of the situation, for up the whole of that long steep hill he had marched at Mokus's head, tugging with all his might at the bridle with one hand, while the other held a huge carrot just beyond the obstinate creature's reach.

Dan was not only hot and tired and out of patience, but he was extremely mortified.
"Where is Betty ?" called Kitty, trying to check her laughter.
Betty, hearing her name, came round from the back of the cart; she was almost purple in the face, and looked quite exhausted.
"I've been pushing," she gasped.
