NOTES FOR FIELD BOTANISTS, &c. 15 
Recording. The following hints are worth noting. 
Make all notes immediately upon observation of the facts ; never 
trust to memory, nor delay recording. 
Make all notes about individual specimens upon detachable sheets, 
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 the truth and accuracy of the 
observation. 
Accompany all notes with maps, drawings, sketches, or photographs 
so 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, e.g.

identity of the specimen. 
As each specimen is gathered, record the date, exact locality, 
elevation above sea-level, habit, colour of flower and fruit, 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
