"That's nothing but a blue dye obtained from a plant," observed Furry, an old, blind rat, who in his days had travelled far, and seen much of the world, and had reflected upon what he had viewed far more than is common with a rat. Indeed, he passed amongst us for a philosopher, and I had learnt not a little from his experience; for he delighted in talking over his travels, and but for a little testiness of temper, would have been a very agreeable companion. He very frequently joined our party; indeed, his infirmities obliged him to do so, as he could not have lived without assistance. But I must now return to Brisk, and his catalogue of the cargo. "Opium--" "The juice of the white poppy," said our aged friend, who had a taste for general information. "I've seen it produce strange effects when eaten in large quantities by men." "What effects?" said I. I was a very inquisitive rat, and especially curious about all that related to the large creatures upon two legs, called Man, whom I believed to be as much wiser as they are stronger than the race of Mus, to which I belong. "Why, opium makes men first wild and bold, so that they will rush into danger or run into folly, quarrel with their friends and fight their foes, laugh and dance, and be merry they know not why. Then they grow sleepy, and though their lives might depend on it, not a step would they stir. Then, when they awake from their unnatural sleep, their bodies are cold, their heads heavy; they feel sick, and faint, and sad! And if this should happen day after day, at last the strong grows weak and the healthy ill, the flesh goes from the bones and the life from the eyes, and the whole man becomes like some old, empty hulk, whose timbers will hardly hold together! And all this from eating opium!" "Ugh!" exclaimed Brisk; "leave opium to man; it is a great deal too bad for rats!" CHAPTER II. A CLAP-TRAP DISCOVERY. With eager haste we scrambled into the warehouse, Furry, as usual, remaining behind on account of his infirmities. We were almost too impatient to wait till the men within should have finished their work, till the doors should be shut and locked, and the place left in quiet for us. I soon found out what was to me a singular curiosity-- a tooth; I felt certain that it was a tooth; but it was twice as long as any rat, counting from the tip of his nose to the end of his tail! I could not help wondering in my mind to what huge animal it could ever have belonged. "Isn't that called ivory?" said Oddity, as he waddled past me. I felt inexpressible pleasure in gnawing and nibbling at the huge tusk, and polishing my sharp teeth upon it. "How I should like to see the enormous rat that could have carried such a tusk!" I exclaimed. "Oh! how I should delight in travelling and seeing the world!" "You've something to see worth the seeing, without travelling far!" cried Brisk. "Such a fragrance of cheese as there is yonder! Why, Ratto, its delicious scent reaches us even here!"
