I Confess, That This
Experiment, Of Which Father Gumilla Speaks, Does Not Always Succeed
Equally Well:
Yet in general it does appear that at great distances
from the shore, and even in an island, these little animals feel with
extreme delicacy in what direction the most humid air prevails.
Reflecting on the almost uninterrupted layer of eggs that extends
along the beach, and on the thousands of little turtles that seek the
water as soon as they are hatched, it is difficult to admit that the
many turtles which have made their nests in the same spot, can
distinguish their own young, and lead them, like the crocodiles, to
the lakes in the vicinity of the Orinoco. It is certain, however, that
the animal passes the first years of its life in pools where the water
is shallow, and does not return to the bed of the great river till it
is full-grown. How then do the tortuguillos find these pools? Are they
led thither by female turtles, which adopt the young as by chance? The
crocodiles, less numerous, deposit their eggs in separate holes; and,
in this family of saurians, the female returns about the time when the
incubation is terminated, calls her young, which answer to her voice,
and often assists them to get out of the ground. The arrau tortoise,
no doubt, like the crocodile, knows the spot where she has made her
nest; but, not daring to return to the beach on which the Indians have
formed their encampment, how can she distinguish her own young from
those which do not belong to her? On the other hand, the Ottomac
Indians declare that, at the period of inundation, they have met with
female turtles followed by a great number of young ones. These were
perhaps arraus whose eggs had been deposited on a desert beach to
which they could return. Males are extremely rare among these animals.
Scarcely is one male found among several hundred females. The cause of
this disparity cannot be the same as with the crocodiles, which fight
in the coupling season.
Our pilot had anchored at the Playa de huevos, to purchase some
provisions, our store having begun to run short. We found there fresh
meat, Angostura rice, and even biscuit made of wheat-flour. Our
Indians filled the boat with little live turtles, and eggs dried in
the sun, for their own use. Having taken leave of the missionary of
Uruana, who had treated us with great kindness, we set sail about four
in the afternoon. The wind was fresh, and blew in squalls. Since we
had entered the mountainous part of the country, we had discovered
that our canoe carried sail very badly; but the master was desirous of
showing the Indians who were assembled on the beach, that, by going
close to the wind, he could reach, at one single tack, the middle of
the river. At the very moment when he was boasting of his dexterity,
and the boldness of his manoeuvre, the force of the wind upon the sail
became so great that we were on the point of going down.
