PRESSING. 
After having collected some specimens, lay one of your boards on the 
floor or on a table, and place three driers upon it; then upon the top of 
the driers lay a sheet of paper which you have prepared for the purpose, 
and open it, letting one half of the sheet lie over upon the table ; then 
lay a plant upon that which rests upon the driers, and after having ar- 
ranged the leaves, flowers, root, and fruit, if it has any, so as to present 
a natural appearance, turn the half sheet over it, and lay upon it three 
more driers, and so on, till you have arranged as many as you wish ; then 
lay the other board upon the top of the whole, and place upon the board 
a weight. A large stone may be used for this purpose, or several may be 
used. Some plants need heavier weights than others. The weight should 
be just sufficient to keep the leaves extended smoothly ; if too much 
is used, it crushes the parts and causes them to turn black. Some plants 
will turn black in defiance of the most careful management. Most her- 
baceous plants change their color to some extent, yet, with care, they will 
retain much of their natural appearance. 
Having left the plants in press for ten or twelve hours, the top board 
should be taken off and laid upon the table beside the pile, three 
fresh driers laid upon it, and the damp ones should then be removed 
from the top of the uppermost plant, and the plant be laid carefully 
upon the top of the three fresh driers without removing it from between 
the folds of the paper in which it was placed; then three fresh driers 
laid upon the top of the plant, and so on till all have been removed, when 
the board that was at the bottom may be laid upon the top, and the 
weight replaced ; the damp driers should then be placed on a line to dry. 7 
This process of changing should be carried on till the plants are in the 
condition of well-cured hay. They may then be remoyed from the press 
and placed between the folds of dry paper, cut to the size of the driers. 
When a plant is put into the press, a bit of paper should be laid in with 
it, on which should be written the generic and specific names of the 
plant ; also the name of the place where it was collected, and the date ; 
and if anything uncommon is noticed about it, this should be mentioned, 
as follows ° 
VIOLA, 
lanceolata ; 
Freehold, Monmouth Co., N. J , 
May 10th, 1856. 
Growing in a peat bog. 
Flowers unusually large. 
plants may be procured, having both flowers and fruit at the same his * 
If possible, they should be procured in that state. If this cannot roa ae 
done, specimens with flowers should be procured, and afterwards, thomas 44 
with fruit. On some plants the flowers appear before the leaves, as is wy 
the case with many trees, in such cases the leaf must be procured after-_
