Travel is the theme of this year's Christmas acrostic. To solve the puzzle, (1) read each clue and (2) write each answer onto the blank spaces (located next to the clues). Then, turn to the diagram and (3) transpose the letters from the answers onto the squares following the numbers and letters indicated in each square.

When all the squares are filled in, a quotation from a work by a famous American writer will emerge. What is the quotation, by whom was it written, and from what work was it taken? (Hint: The initial letters of the answers to the clues -- read vertically -- spell out the name of the author and the title of the work from which the quotation was taken.)

All entries (one per person) must be clearly written on postcards and mailed to: Book Bag, The Washington Post, Washington, D.C. 20071, and must include complete return address and competition number. The winning entry will be the first correct answer drawn at random. Employees of The Washington Post Company and their families are not eligible to enter. Entries must be received no later than Dec. 13. The winners' (there will be five) names and cities of residence will be announced in the Dec. 23 issue. A Washington Post Book World book bag will be sent to each of the winners. Answer to Book Bag #601: The novel of unrequited love which supposedly caused an epidemic of suicides by unhappy lovers all over Europe is Johann Wolfgang von Goethe's "The Sorrows of Young Werther." Winner: Tina Eyring, Glen Burnie, Md.
