TO PRESS SPECIMENS 
In lieu of a special Botanical Press when on field expeditions, 
experience has proved that the best manner to preserve specimens 
is to place them in wet newspapers, turning in the ends of the 
paper to exclude the air until they can be transferred to fresh, dry 
newspapers, and be placed under heavy weights. Carefully lay out 
the specimen to show the flower, or that characteristic specially 
desired (passing a slightly heated iron over the paper covering it, 
is suggested as an aid in preserving color) before placing under 
pressure.
