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.'"

"The drum is in hands that will know how to beat it well enough," said
Sancho Panza.

When he had said this and finished the tying (which was not over the
armour but only over the doublet) Don Quixote observed, "It was careless

voice offered up a prayer to heaven, imploring God to aid him and grant
him success in this to all appearance perilous and untried adventure, and
then exclaimed aloud, "O mistress of my actions and movements,
illustrious and peerless Dulcinea del Toboso, if so be the prayers and
supplications of this fortunate lover can reach thy ears, by thy
incomparable beauty I entreat thee to listen to them, for they but ask
thee not to refuse me thy favour and protection now that I stand in such
need of them. I am about to precipitate, to sink, to plunge myself into
the abyss that is here before me, only to let the world know that while
thou dost favour me there is no impossibility I will not attempt and
accomplish." With these words he approached the cavern, and perceived
that it was impossible to let himself down or effect an entrance except
by sheer force or cleaving a passage; so drawing his sword he began to
demolish and cut away the brambles at the mouth of the cave, at the noise
of which a vast multitude of crows and choughs flew out of it so thick
and so fast that they knocked Don Quixote down;
