A thin-bladed knife or scalpel with a keen edge is used for 
cutting these sections, which must be cut very thin. The see 
tions, as cut from the fresh plants, are arranged as naturally and 
artistically as possible on the gummed side of a rectangular 
piece of gummed paper just large enough for them. A pieceal 
waxed paper such as florists and confectioners use is laid over 
the sections and it must also cover all the exposed gumme — 
surface of the gummed paper. The combination of gummel — 
sheet, sections and waxed paper is placed between sheets of — 
light weight blotting paper and driers in a plant press and dried 
rapidly under heavy pressure. The sections adhere to tht 
gummed sheet, retain their colors better than by any other 
method with which I am familiar, and do not shrink much® — 
drying. When they are quite dry, the waxed paper may Me 
lifted from the preparations and the gummed sheet. I glue the 
back of the gummed paper at the corners against the upper pat 
of the card bearing the envelope of dried plants of the same 
collection, as shown in fig. 4, with the collection at the right bane 
corner of the species sheet.
