I thought the shortest sentence from _A Princess of Mars_ was "Sak!" For those who do not know, "Sak!" is Barsoomian (Martian) for "Jump!" Quote: They first repeated the word "sak" a number of times, and then Tars Tarkas made several jumps, repeating the same word before each leap; then, turning to me, he said, "sak!" I saw what they were after, and gathering myself together I "sakked" with such marvelous success that I cleared a good hundred and fifty feet; nor did I, this time, lose my equilibrium, but landed squarely upon my feet without falling. I then returned by easy jumps of twenty-five or thirty feet to the little group of warriors.
