"A Tangled Tale" book is a collection of 10 humorous stories by Lewis Carroll. The stories, or Knots as Carroll calls them, present mathematical problems. The appendix is included and in it, Carroll gives the solutions to the Knots but beware, the mathematical interpretations of the Knots are not always straightforward."Goblin, lead them up and down." The ruddy glow of sunset was already fading into the sombre shadows of night, when two travellers might have been observed swiftly-at a pace of six miles in the hour-descending the rugged side of a mountain; the younger bounding from crag to crag with the agility of a fawn, while his companion, whose aged limbs seemed ill at ease in the heavy chain armour habitually worn by tourists in that district, toiled on painfully at his side. As is always the case under such circumstances, the younger knight was the first to break the silence. "A goodly pace, I trow!" he exclaimed. "We sped not thus in the ascent!" "Goodly, indeed!" the other echoed with a groan. "We clomb it but at three miles in the hour." "And on the dead level our pace is--?" the younger suggested; for he was weak in statistics, and left all such details to his aged companion. "Four miles in the hour," the other wearily replied. "Not an ounce more," he added, with that love of metaphor so common in old age, "and not a farthing less!" "'Twas three hours past high noon when we left our hostelry," the young man said, musingly. "We shall scarce be back by supper-time. Perchance mine host will roundly deny us all food!" "He will chide our tardy return," was the grave reply, "and such a rebuke will be meet."
