In Three Parts
Part First How the Animals of the Wood Sent out a Scientific Expedition
Once the creatures of the forest held a great convention and appointed a commission consisting of the most illustrious scientists among them to go forth，clear beyond the forest and out into the unknown and unexplored world，to verify the truth of the matters already taught in their schools and colleges and also to make discoveries.It was the most imposing enterprise of the kind the nation had ever embarked in.True，the government had once sent Dr.Bull Frog，with a picked crew，to hunt for a northwesterly passage through the swamp to the right-hand corner of the wood，and had since sent out many expeditions to hunt for Dr.Bull Frog；but they never could find him，and so government finally gave him up and ennobled his mother to show its gratitude for the services her son had rendered to science.And once government sent Sir Grass Hopper to hunt for the sources of the rill that emptied into the swamp；and afterward sent out many expeditions to hunt for Sir Grass，and at last they were successful—they found his body，but if he had discovered the sources meantime，he did not let on.So government acted handsomely by deceased，and many envied his funeral.
But these expeditions were trifles compared with the present one；for this one comprised among its servants the very greatest among the learned；and besides it was to go to the utterly unvisited regions believed to lie beyond the mighty forest—as we have remarked before.How the members were banqueted，and glorified，and talked about!Everywhere that one of them showed himself，straightway there was a crowd to gape and stare at him.
Finally they set off，and it was a sight to see the long procession of dry-land Tortoises heavily laden with savants，scientific instruments，Glow-Worms and Fire-Flies for signal service，provisions，Ants and Tumble-Bugs to fetch and carry and delve，Spiders to carry the surveying chain and do other engineering duty，and so forth and so on；and after the Tortoises came another long train of ironclads—stately and spacious Mud Turtles for marine transportation service；and from every Tortoise and every Turtle flaunted a flaming gladiolus or other splendid banner；at the head of the column a great band of Bumble-Bees，Mosquitoes，Katy-Dids，and Crickets discoursed martial music；and the entire train was under the escort and protection of twelve picked regiments of the Army Worm.
At the end of three weeks the expedition emerged from the forest and looked upon the great Unknown World.Their eyes were greeted with an impressive spectacle.A vast level plain stretched before them，watered by a sinuous stream；and beyond there towered up against the sky a long and lofty barrier of some kind，they did not know what.The Tumble-Bug said he believed it was simply land tilted up on its edge，because he knew he could see trees on it.But Professor Snail and the others said:
“You are hired to dig，sir—that is all.We need your muscle，not your brains.When we want your opinion on scientific matters，we will hasten to let you know.Your coolness is intolerable，too—loafing about here meddling with august matters of learning，when the other laborers are pitching camp.Go along and help handle the baggage.”
The Tumble-Bug turned on his heel uncrushed，unabashed，observing to himself，“If it isn't land tilted up，let me die the death of the unrighteous.”
Professor Bull Frog (nephew of the late explorer)said he believed the ridge was the wall that inclosed the earth.He continued:
“Our fathers have left us much learning，but they had not traveled far，and so we may count this a noble new discovery.We are safe for renown now，even though our labors began and ended with this single achievement.I wonder what this wall is built of？Can it be fungus？Fungus is an honorable good thing to build a wall of.”
Professor Snail adjusted his field-glass and examined the rampart critically.Finally he said:
“The fact that it is not diaphanous convinces me that it is a dense vapor formed by the calorification of ascending moisture dephlogisticated by refraction.A few endiometrical experiments would confirm this，but it is not necessary.The thing is obvious.”
So he shut up his glass and went into his shell to make a note of the discovery of the world's end，and the nature of it.
“Profound mind!”said Professor Angle-Worm to Professor Field-Mouse；“profound mind!nothing can long remain a mystery to that august brain.”
Night drew on apace，the sentinel crickets were posted，the Glow-Worm and Fire-Fly lamps were lighted，and the camp sank to silence and sleep.After breakfast in the morning，the expedition moved on.About noon a great avenue was reached，which had in it two endless parallel bars of some kind of hard black substance，raised the height of the tallest Bull Frog above the general level.The scientists climbed up on these and examined and tested them in various ways.They walked along them for a great distance，but found no end and no break in them.They could arrive at no decision.There was nothing in the records of science that mentioned anything of this kind.But at last the bald and venerable geographer，Professor Mud Turtle，a person who，born poor，and of a drudging low family，had，by his own native force raised himself to the headship of the geographers of his generation，said:
“My friends，we have indeed made a discovery here.We have found in a palpable，compact，and imperishable state what the wisest of our fathers always regarded as a mere thing of the imagination.Humble yourselves，my friends，for we stand in a majestic presence.These are parallels of latitude!”
Every heart and every head was bowed，so awful，so sublime was the magnitude of the discovery.Many shed tears.
