under my experience, outside of the “ Zive-for-ever” family and their 
neighbors, is Liparis lilifolia. This plant has frequently kept me 
squeezing away at it for several weeks (when not using heated driers) 
but I have generally succeeded in making it retain its natural color 
at last. With warm driers the colors may be retained of nearly all 
the Orchidaceous and Liliaceous groups, the Baptisias, the Gerar- 
dias (I fail with G. fava) and many other plants which become dis- 
colored in drying. 
If the leaves of thick, fleshy plants are immersed for a few 
moments in hot water, it will hasten their period of desiccation, 
although they often turn dark in pressing as a consequence of the 
immersion. Many of the endogenous plants and others, if desirable, 
may be ironed in their driers with gratifying success. Some botan- 
ists recommend putting fleshy endogens and other succulent plants 
in a separate press near the stove, where they claim plants may be 
dried in a few days. For these plants the writer,prefers using heated. 
driers. 
Small plants may be handsomely dried in old books. If only a 
few specimens are placed in the book, they may be dried without 
once shifting. Not a heavy pressure should be used. On removal 
of plants, dry the book for again using, by spreading open -in the 
sunshine, or hanging on a line near the fire. 
It may sometimes be convenient to dry certain plants by placing 
them in a suitable vessel and covering (sifting) with warm dry sand. 
In a day or two they will be found nearly free from moisture, when, 
if expedient, they may be transferred to the press. 
Viscous plants and those likely to adhere to the sheets enclosing 
them may have Lycopodium, powdered soapstone, or some similar 
substance sprinkled over them to prevent their sticking. In the 
absence of any of these powders I have used fine white sand with 
fair success. 
In changing the driers of the plants, place the package to be 
changed at left hand on the table or counter, the new pile in front 
of the sitter, with its length parallel, a position” the most favorable — 
for giving any needed attention in arranging-specimens, while the 
fresh driers may be placed at right hand, or beyond the pile in front. 
Thus arranged, the sheets of specimens can be rapidly shifted into 
their fresh driers. 
The driers and packets may be dried in several ways. The 
packets may be hung on a line in a warm room, or in the open air © 
when not too windy ; the driers, after the dew has disappeared, may 
be spread on the grass. A better way, for the latter, if you have the 
room, is first to lay down in a sunny place a covering of old boards, 
sticks, brush, or anything to keep them from the ground. A favor- 
ite place with the writer, on a still day, is on the top of a flattish tin- 
roof, where, exposed to a fierce radiating heat on one side and the 
direct’ rays of the sun on the other, the driers and packets dry per- 
fectly in a few minutes. . 
Always spread your moist driers in the sunshine when possible, 
and then at longest they will dry within an hour, unless put out too late _ : 
in the day. Do not leave them too late in the day, as the dew falls
