As they were thus proceeding, then, they discovered a small boat, without oars or any other gear, that lay at the water’s edge tied to the stem of a tree growing on the bank. Don Quixote looked all round, and seeing nobody, at once, without more ado, dismounted from Rocinante and bade Sancho get down from Dapple and tie both beasts securely to the trunk of a poplar or willow that stood there. Sancho asked him the reason of this sudden dismounting and tying. Don Quixote made answer, “Thou must know, Sancho, that this bark is plainly, and without the possibility of any alternative, calling and inviting me to enter it, and in it go to give aid to some knight or other person of distinction in need of it, who is no doubt in some sore strait; for this is the way of the books of chivalry and of the enchanters who figure and speak in them.
