“What’s inside it?” asked the Mole wriggling with curiosity.

“There’s cold chicken inside it”, replied the Rat briefly: “cold-tongue-cold-ham-cold-beef-pickled-gherkins-salad-french-rolls-cress-sandwiches-potted-meat-ginger-beer-lemonade-soda-water…”

“Oh, stop”, cried the Mole in ecstasies. “This is too much for one picnic. We can have another tomorrow on what’s left”.

“Do you really think so?” inquired the Rat seriously. “Let’s see. There’s only salad-pickled-gherkins-french-rolls-and-soda-water enough for two days: so if we have ham today we’ll have beef tomorrow; if we have potted meat today we’ll have cress sandwiches tomorrow; and if we have tongue today we’ll have lemonade tomorrow”.

“If we save the cress sandwiches for tomorrow we’ll have the beef today; if we keep the potted meat for tomorrow we’ll have the ginger beer today; and if we keep the lemonade for tomorrow we’ll have the ham today”. The Mole was entering into the spirit of the thing.

“In any event we’ll have the lemonade and ginger beer on different days, and likewise the beef and the chicken”, Rat shrieked excitedly.

“And if we have the chicken and cress sandwiches together, we’ll have the potted meat the day after we have the tongue”. The Mole rolled on his back at the prospect. “And we’ll eat every scrap”.

Which of the eight items did they save for the second day?
