104 Leaf Buds 



PRACTICAL WORK. 



1. Take all the leaves carefully off your Brussels sprout, and 

 arrange them on a sheet of paper. Draw the 1st, 10th, 20th, 30th 

 leaves twice natural size, also the axis when all the leaves are re- 

 moved. 



2. Draw the various twigs natural size and write by the side of 

 each drawing the age of the twig. 



3. Dissect a horse-chestnut bud and a beech bud, noticing care- 

 fully the arrangement of the scales and the way the young leaves are 

 folded. Leave the dissected buds on a sheet of paper for inspection. 

 (The use of a pocket lens will be found to be helpful, but is not 

 essential.) 



4. Date your paper. Write in column a complete list of the 

 trees in the school garden. Write opposite the name of each tree in 

 what condition you find it, e.g. ' leaf buds bursting,' ' in full flower,' 

 etc. 



HOME WORK. 



Draw the opening leaves of any one tree in as many stages as you 

 can find them, or keep some willow twigs in water and draw them 

 once a week during the holidays.
