The Leaf 121 



Sometimes the leaf is smooth and shiny, like a laurel 

 leaf, or again it may be covered with a waxy coat or 

 with hairs. 



These diiferences are only to be found on the upper 

 surface, as the under one does not run the same risk. 



An advantage of learning some of the words like 

 palmate, pinnate, simple, compound, entire, wavy, lobed, 

 which are printed in black type in this lesson, is that 

 you can then make one word do instead of a dozen 

 when you try to describe some new leaf. 



PRACTICAL WORK. 



1. Place one of your pressed leaves (if impressed leaves are used 

 their dampness may spoil the printing paper) in the printing frame 

 with the sensitive paper. Make the print just as you did in your 

 last home work, but leave it just long enough to get a good impression 

 of the veins. Wash it and put it on one side to dry. While it is 

 printing go on with the other questions. 



2. Trace the outlines of the leaves supplied, e.g. lime, guelder 

 rose or vine, iris, birch, dogwood, blackberry, and finish in ink. 



3. Write down which of the following leaves are simple and 

 which compound, and if compound the number of leaflets : horse- 

 chestnut, hawthorn, maple, pine, blackberry, rowan or robinia. 



4. Draw each of the following leaves and describe exactly, but 

 in as few words as possible, their shape, venation, margin, and 

 surface : ash, oak, maple, ivy, willow, elm. 



HOME WORK. 



Draw a twig with leaves in natural position, attending to all you 

 have learnt about the shape of the leaves, their arrangement on the 

 stem, etc. Finish in ink.
