around 600 ft. than lower down, as Polypodium squamatum 
grows from the lava crevices at this elevation. There are also a 
considerable number of small trees of Zanthoxylum Fagara in 
this vicinity which is near the base of the high hill on the south¬ 
west side of the island. The top of this hill is covered with 
bushes of Cordia galapagensis, Cryptocarpus pyriformis, Ly- 
cium geniculatum, Tournefortia psilostachya, and Vallesia gla¬ 
bra. Ipomoea Habeliana covers the. rocks here to a considerable 
extent. 
Indefatigable Island. 
Indefatigable is the second largest, and with the exception of 
Duncan, is the most centrally located island in the group. It is 
roughly circular in outline, and appears to have a large central 
crater when seen from the south side. There is probably no 
larger crater present, however, because in sailing around the is¬ 
land towards the west side it is seen that the upper part is cov¬ 
ered with many small craters, twenty-one of which were counted. 
Small lateral craters also occur at various places along the sides, 
the largest one of which is on the southeast side of the mountain 
a short distance below the top. 
The shores along the south, southeast, and east sides of the is¬ 
land are bordered by low rocky cliffs of lava in most places, 
while on the other sides the shores are low with occasional sand 
beaches. There is a large bay on the south side which we chris¬ 
tened it Academy Bay in honor of the California Academy of 
Sciences. 
The sides of the island slope up very gradually on all sides so 
that it is necessary for one to travel several miles inland in order 
to get into the region where collecting is good. All of the lower 
parts are covered with the usual xerophytic forms so common on 
these islands, but which are not in proper condition for collect¬ 
ing through a greater part of the year. The lower parts are 
covered with lava on which there is but little soil, but in the in¬ 
terior there is an abundant soil, and in places there is said to be 
water, although we were not fortunate enough to find it. The 
interior of this island is very fertile, and with proper cultivation 
is capable of supporting quite a large population, but up to the 
time we visited it no attempt had been made to establish a 
settlement there. 
We visited the island at Academy Bay, at two places on the
