It was four o'clock in the afternoon.

Aramis, on observing this, judged that nothing showed pursuit to be a possibility.

It would be without example that a troop capable of taking him and Porthos should be furnished with relays sufficient to perform forty leagues in eight hours.

Thus, admitting pursuit, which was not at all manifest, the fugitives were five hours in advance of their pursuers.
Aramis thought that there might be no imprudence in taking a little rest, but that to continue would make the matter more certain.

Twenty leagues more, performed with the same rapidity, twenty more leagues devoured, and no one, not even D'Artagnan, could overtake the enemies of the king.
