of your circles and mark on the largest circle the position of the 

 lowest leaf, on the next circle the next leaf, and so on. Leave paper 

 and twig for inspection. (Fig. 58 gives an example.) 



HOME WORK. 



Arrange your pressed ivy leaves on the glass of the printing 

 frame with their front sides against the glass. Fit different sized 

 leaves together so that none of them overlap and they make a nice 

 pattern. Put a sheet of blue printing paper over them. Then put

 from hour to hour. When all details, such as veins, have nearly 

 disappeared take the print out and wash it in cold water. Make 

 several prints and find out what length of time gives the best results. 

 Write in pencil on the back of the print how long you were printing 

 it and what sort of day it was sunny, cloudy, etc. 



Lesson 3. THE VEINS, SHAPE, MARGIN AND

Season. Third week in May. 

 Materials required for each pupil. 



One of each of the following leaves: Iris, lime, 

 maple, ash, guelder rose or vine, beech, dogwood, black- 

 berry, horse-chestnut, hawthorn, pine (Scotch), rowan 

 or robinia, oaJc, ivy, willow, elm. Pressed leaves (from 

 first lesson). Quarter plate printing frames. (If these 

 are not available in sufficient number, sheets of glass 

 may be tried alone.) Ferro-prussiate printing paper 

 to fit the frame. Basins of water for washing the 

 prints. 



The veins of a leaf, besides strengthening the thin 

 blade, act very much as our veins do, that is they 

 supply every part of the leaf with sap. Every vein,
