Although he tries not to allow himself to be distracted by other
thoughts, from time to time sounds from the outer world disturb his
pious meditations. First it is the joyous song of a bird. To these
vibrating notes another song replies from afar, on a more simple and
almost plaintive key. It is doubtless the female, who, with a sort of
modest and repressed tenderness, thus announces her retreat to him who
calls; then a rapid rustling is heard above the head of the prisoner.
It is the songster, hastening to rejoin his companion.

Selkirk has never known love. Once perhaps,--in a fit of youth and
delirium; and it was this false love which tore him from his studies,
from his country!

Ah! why did he not remain at Largo, with his father? To-day he also
would have had a companion! In that smiling country where coolness
dwells, where labor is so easy, life so sweet and calm, the paternal
roof would have sheltered his happiness! Oh! the joys of his infancy!
his green and sunny Scotland.

The regrets which arise in his heart he quickly banishes; his dear
remembrances he sacrifices to God; he weaves them into a fervent
prayer.

Very soon an approaching bleating rouses him again from his
abstractions. A goat, with restless eye, has just stretched her head
over the edge of the precipice, and for an instant fixes on him her
astonished glance. Then, as if re-assured, defying his powerlessness,
with a disdainful lip she quietly crops some tufts of grass growing on
the verge of the tunnel.
