3. A list of all the apple blossom visitors observed, with 

 data as far as obtainable incorporated in a table prepared 

 with the following column headings : 



Name (of the insect; ask the instructor if you do not 



know it). 

 Seeking (pollen or nectar. Do not guess at this; better 



leave the space blank). 



Alights where (touching what parts of the flower). 

 Carries pollen on (what parts of the body). 

 Touches stigmas with (what parts of the body). 

 Reaches nectar with (what proportion of proboscis, or of 

 whole body, inserted into the flower) 

 f per minute. 

 Number of flowers visited < between flights (i. e. between

 Activity (relatively quick or slow, wary or approachable, 



direct or circuitous, etc.).

If there be any difficulty arising out of the crowd, conclud- 

 ing observations may, with advantage, be made individually, 

 at one's own convenience.
