numbered to correspond with the specimens ; never describe two or 

 more on the same sheet ; never use the same number twice. 



Make no record till satisfied of its truth and accuracy. 



Accompany all notes with maps, drawings, sketches, or photographs 

 as far as possible. 



Sketch and photograph all peculiarities of habit, characteristic forms 

 of vegetation, and other features of interest. Mark all plants in such 

 pictures with numbers corresponding to their numbers in your collection, 

 and write a full description of each picture before leaving the spot. If 

 a photograph is taken, make a rough sketch (from the picture on the 

 focussing screen or finder) of the scene and put numbers to the plants. 



Label all specimens as collected with consecutive numbers, and 

 subsequently with permanent labels (about 3x2 inches) giving name 

 of herbarium, collection, tour or district in which they were collected, 

 date, locality, and collector, as well as the number. 



As each specimen is gathered, record date, exact locality, elevation 

 above sea, habit, colour of fl. and fr., scent, presence or absence of 

 honey, floral mechanism, insect visits, and any other features and facts 

 that cannot be ascertained from the specimens preserved. 



Note the comparative frequency of each species, the kind of situation 

 and soil it affects, and the species with which it is found in association. 



Endeavour to note the chief general forms of vegetation and the 

 local grouping of pi. in districts studied. Pay special attention to 

 ecological and geographical questions. 



Record native names (question several different persons before 

 deciding), economic uses, and points of general or ethnological interest.
