of the mountain where he thought we could arrange to stay,so we took our 
pack-mule with us,with the idea of leaving our pack at the house,while 
we continued on to the summit,in order to get some idea what the con¬ 
ditions were on the mountain itself. 
I found this house to he at 2150 feet altitude,just at the lower 
edge of the vast forest which clothes the greater portion of the volcano. 
The pack was left thereafter arrangements had been made with the owner 
to furnish us with food and lodging,and we continued upward,hut our 
guide proved to he no guide at all,and the day was practically lost,

approximately 5550 feet. 
The work was seriously handicapped by two severe and totally unex¬ 
pected "nortes",both bringing rain and heavy mist above 3000 feet,but

taken elsewhere,8 of which were resident species,belonging to the 
lower subtropical zone. 
We returned to Tres Zapotes on Wednesday,April 24th,and that night 
I continued on to the Boca de San Miguel to sleep,in order to catch the 
launch for Tlacotalpam early the next morning. I had resolved to go at 
once to Mexico City in order to arrange for the exportation of my
