‘The stroke on the left might be a G-rune with thin branches,’ said Strider. ‘It might be a sign left by Gandalf, though one cannot be sure. The scratches are fine, and they certainly look fresh. But the marks might mean something quite different, and have nothing to do with us. Rangers use runes, and they come here sometimes.’ ‘What could they mean, even if Gandalf made them?’ asked Merry. ‘I should say,’ answered Strider, ‘that they stood for G3, and were a sign that Gandalf was here on October the third: that is three days ago now. It would also show that he was in a hurry and danger was at hand, so that he had no time or did not dare to write anything longer or plainer. If that is so, we must be wary.’
