ant collections were made. The trip to Lake Atitlan was made 
from Patalul which proved to be a charming repetition in the 
main of the route before described to Quezaltenango. This may 
be described in connection with another considerable mountain- 
lake, namely Amatitlan. 
LAKES ATITLAN AND AMATITLAN. 
Besides the great Lake Izabal near the east coast in De¬ 
partment of same name and Lake San Andre or Peten in the 
middle of the Department of El Peten — neither included in the 
itinerary of 1905 and 1906 — the only other very large bodies 
of water in the interior of Guatemala are the mountain lakes of 
Amatitlan, in the Department of same name, and Atitlan, in 
the Department of Solala. These lakes are 7 or 8 miles in 
length; Atitlan is 6 or 7 miles wide, but Amatitlan has a width 
of only one mile near the middle and about 3 miles exclusive of 
this narrow neck. They are alike in having for the most part 
walls of rather steep sloping mountains — yet the flat area on 
the north side of Amatitlan is very great — being the debris of 
ages brought down by the drainage from the north, finding its 
way into this mountain-hemmed basin mainly through the river 
emptying in the Lake at the middle and now greatly narrowed 
part. There is no visible outlet to Lake Atitlan; Rio Michatoya 
drains Lake Amatitlan Pacific-ward. This lake is only about 
one hundred feet deep, but some parts of Lake Atitlan are over 
1,000 feet in depth. Much time was spent on Lake Amatitlan 
to which then the following more particularly applies. The 
marked xerophytic character of the shore vegetation, as well as 
that of the slopes, was striking. Cacti were rather abundant; 
Acaciae and Mimosae were common; the Agaves were not rare; 
and hosts of Compositae , Leguminosae, Labiatae, etc., were 
present. One species of fleshy Asclepias grew on the shore; 
some species of Ficus were common; a giant Equisetum was en¬ 
countered ; groves of Salix humboldtiana were conspicuous; and 
epiphytic orchids, cacti, and bromeliads abounded. The para¬ 
sitic fungi in due quantity were at hand and later reports will 
show that many species were here collected. 
THE VOLCANOES AGUA, ATITLAN AND SANTA MARIA. 
Collections were made on three of the very high volcanoes, 
namely Agua, Atitlan and Santa Maria, also on Cerro Quemado 
and the lower part of Acatenango. The altitudes of the first 
three are 12,300, 11,500 and 11,360 feet respectively. Agua, situ¬ 
ated in the Department Sacatepequez, is clothed with vege¬ 
tation to the very apex and on the interior of the rather small 
crater — coarse grasses, some shrubs and a few stunted trees. 
A heavy belt of timber encircles the cone reaching a line within
