CENTRAL AMERICAN RAINFALL.

ten in all, nine in Alta Verapaz. The latter department 
is on the northern slope of an eastern and western moun¬ 
tain range, apparently the Sierra de las Minas of the maps, 
but if so the maps are wrong or the range has moved 15' or 
20' north in latitude since the maps were made; but there 
are many things on the maps of Guatemala which are not 
in Guatemala itself, and vice versa. As the reports from the 
various stations in Alta Verapaz are fragmentary, I have 
generally combined them into one and used that as a repre¬ 
sentative value. 
There is, so far as I am informed, not a rainfall observa¬ 
tion from the Republic of Honduras, and I have therefore 
pieced out my information there by reports of travelers, 
especially Squier, and by statements made to me when I 
visited that country some years ago. 
The information along the proposed routes of the Nica¬ 
ragua canal is considerable, though fragmentary, except at 
Rivas. At San Jose Dr. Pittier established three outlying 
stations, at one of which, Heredia, observations had been 
taken before. Of these three stations Agua Caliente proves 
very interesting, as it has a transition rainfall between that 
of the eastern and western coasts. 
Of those who have previously studied the Central Ameri¬ 
can rainfall we may mention the papers of Dr. Moritz 
Wagner,* Dr. A. von Frantzius,t Pittier, { and the more 
general studies shown in rainfall publications of Schott, of 
Loomis, and those of Koeppen § and Hann.||
