it was not very easy to know what would poison a dragon, because, you see, they ate such different things. the largest kind ate elephants as long as there were any, and then went on with horses and cows. another size ate nothing but lilies of the valley, and a third size ate only prime ministers if they were to be had, and, if not, would feed freely on servants in livery. another size lived on bricks, and three of them ate two thirds of the south lambeth infirmary in one afternoon.
