The second method is called the strip method. It consists of fasten- 

 ing the principal parts of the specimen to the sheet by means of tiny 

 strips of gummed paper or surgeons' silk. This gummed paper can 

 either be made at home or bouglit in bulk and used as needed. 



In general, it is best to use no more fastening than is necessary to 

 hold the plant firmly. Strips should be small and should be put on as

neatly and uniformly as possible. The points most in need of fasten- 

 ing are the base, the center and the head. A lateral branch which is 

 apt to be broken should also be fastened. 



The question at once arises: How many specimens shall be put on 

 one sheet? A good rule to follow is to use enough material to present 

 a good appearance without crowding. Never put more than one 

 species on the same sheet, and never put away a sheet without the 

 label.
