Appendix IV 157 



6. What are the small rosy red cones on the larch trees ? What 

 else do you find on the same trees ? 



7. Which come first on the oak trees, the leaves or the catkins ? 

 or are neither out yet ? 



8. Do you find more than one sort of catkin on the bog myrtle ? 

 If so, do they grow on the same bush or on different bushes ? 



Thorns and Climbing plants (out of doors, to be taken in 

 summer if possible). 



1. Write a list of all the climbing plants you can find in the 

 garden. Say for each how it climbs. Tabulate thus : 



Name of plant 

 Pyrus japonica 

 Ampelopsis 



How it climbs 

 bits of cloth and nails 

 suckers 



2. Draw a full-grown tendril of cucumber which is stretching 

 out into the air of a greenhouse. Don't touch it ; but try to get the 

 drawing exactly life-size and exactly as much curved as the object. 

 Now stroke the tendril gently with your pencil on the concave side 

 of its curvature. Draw it again a few minutes later. 



3. Cut some sprays of white bryony, and put them quickly into 

 warm water. If you can, avoid touching the tendrils. Repeat the 

 cucumber experiment described above. 



4. Bring some sweet pea tendrils just into contact with twigs 

 on to which they might cling. Examine them again next day. Have 

 they caught hold ? 



5. Visit a patch of nettles, and learn all you can from them. 

 Then write an essay " On Nettles." Read Lord Avebury's British 

 Flowering Plants, pp. 355357, on "Urtica." Go back to the 

 nettle patch, and see what more there is to learn. 



6. Collect the three most spiny holly leaves you can find and 

 also the three least spiny. Draw all six. Can you also find inter- 

 mediate patterns ? 



7. Draw the thorns of blackthorn, barberry, gooseberry, and 

 explain how they differ from each other.
