where the weather was so wet that we had rain every day during the month of

My plan for phenogams and mosses was only perfected last year, and for 
phenogams would be of no use without the thick and heavy driers. For the 
past four years I have been in the habit of placing my sheets of specimens when 
partly dry on a level surface of dry rock, earth or sand, and then exposing them 
covered with a single drier to the sun. This worked well in dry weather, but 
keep the collection of each day by itself. Every morning before leaving camp 
I go over all the specimens exposed the day before and label and put away the

region and all my specimens kept their color, although for weeks together it
