plants with which they always associate die as the 
ground dries, and when the salt water ceases to 
bathe them. Centuries after, their decayed trunks, 
covered with shells, and half buried in the sand, 
mark both the route which they have followed in 
their migrations, and the limit of the land which 
they have wrested from the ocean.” 
Cape Codera, seven miles distant from the Bay of 
Iliguerota, is more imposing on account of its mass 
than for its elevation, which appeared to be only 
1280 feet. It is precipitous on the north, west, and 
east. Judging from the fragments of rock found 
along the coast, and from the hills near the town, 
it is composed of foliated gneiss, containing nodules 
of reddish felspar, and little quartz. The strata 
next the bay have the same dip and direction as the 
great mountain of the Silla, which stretches from 
Caraccas to Maniquarez in the Isthmus of Araya, 
and seem to prove that the primitive chain forming 
that neck of land, after being disruptured or swal- 
lowed up by the sea along an extent of 121 miles, 
reappears at Cape Codera, and runs westward in an 
unbroken line. Toward the north the cape forms 
an immense segment of a sphere, and at its foot 
stretches a tract of low land, known to navigators 
by the name of the Points of Tutumo and of San 
Francisco. 
The passengers in the boat dreaded the rolling in 
a rough sea so much, that they resolved to proceed 
to Caraccas by land, and M. Bonpland, following 
their example, procured a rich collection of plants. 
Humboldt, however, continued the voyage, as it 
seemed hazardous to lose sight of the instruments. 
Setting sail at the beginning of the night they
