APPENDIX I. 
Llerbaria.—A herbarium is a collection of pressed and 
dried plants, usually arranged in their various natural orders. 
Betore such a collection can be made some or all of the 
following must be obtained :— 
1. Portfolios, for pressing plants as collected; made of 
two strong pasteboards with encircling straps and handle, 
and containing sheets of paper. 
2. A collecting tin or vasculum for bringing plants home ; 
also several small tins for little plants. 
3. Presses for drying plants made of iron frames filled in 
with wire netting. The papers lie between the frames, which 
are provided with strong straps or frames to obtain the 
necessary pressure. If these presses are unobtainable, 
heavy books can be used instead. 
4. Drying paper.—Stout manila paper is best, but blotting 
paper can be used. 
5. Mounting paper in large sheets 164 x 104 inches. 
6. Mercurie Chloride for poisoning, and Naphthalin for 
keeping away insects. 
7. Alcohol for preserving specimens for subsequent micro- 
scopic examination. 
Collecting.—The first step in making a herbarium is of 
course to collect the specimens. This must be done in fine 
weather ; specimens collected in wet weather will seldom dry 
satisfactorily and are always apt to be attacked by mould.
