"for there are some who weary themselves out in learning and proving
things that, after they are known and proved, are not worth a farthing to
the understanding or memory."

In this and other pleasant conversation the day went by, and that night
they put up at a small hamlet whence it was not more than two leagues to
the cave of Montesinos, so the cousin told Don Quixote, adding, that if
he was bent upon entering it, it would be requisite for him to provide
himself with ropes, so that he might be tied and lowered into its depths.
Don Quixote said that even if it reached to the bottomless pit he meant
to see where it went to; so they bought about a hundred fathoms of rope,
and next day at two in the afternoon they arrived at the cave, the mouth
of which is spacious and wide, but full of thorn and wild-fig bushes and
brambles and briars, so thick and matted that they completely close it up
and cover it over.

On coming within sight of it the cousin, Sancho, and Don Quixote
dismounted, and the first two immediately tied the latter very firmly
with the ropes, and as they were girding and swathing him Sancho said to
him, "Mind what you are about, master mine; don't go burying yourself
alive, or putting yourself where you'll be like a bottle put to cool in a
well; it's no affair or business of your worship's to become the explorer
of this, which must be worse than a Moorish dungeon."

"Tie me and hold thy peace," said Don Quixote, "for an emprise like this,
friend Sancho, was reserved for me;" and said the guide, "I beg of you,
Senor Don Quixote, to observe carefully and examine with a hundred eyes
everything that is within there; perhaps there may be some things for me
to put into my book of 'Transformations.'"
