Winter Suds and Tree Forms 



where strong winds nearly always blow from the same 

 direction, trees are often apt to grow one sided and to 

 look as if all their branches had been blown out like 

 long hair (Fig. 24). What has really happened is that 

 the buds on the windy side have always been nipped 

 back by the cold, while the sheltered ones have been 

 able to grow to their proper size.

PRACTICAL WORK. 



1. Draw the leaf scars of the twigs provided x 6. Show in your 

 sketches the bundles of veins in the scars, and write underneath the 

 name of each twig. 



2. Draw any three of the twigs life size with the buds growing 

 on them. Draw one of the buds by the side of each x 6, and put the 

 names underneath. 



3. Draw two diagrams and show the branching of imaginary 

 trees with the chief branches leaving the trunk at right angles and 

 (a) buds developing inwards, (6) buds developing outwards.
