CHAPTER III. PLANT PROPAGATION. 



1. Pupils may start home projects in the growing of 

 nursery trees of apple, peach, and plum trees and also grape 

 vines. 



2. Bush fruits may be propagated at home for sale to 

 others. 



CHAPTER V. KINDS OF SOIL. 



1. In regions where soil is quite variable, students should

2. In springtime test the fact that drainage warms the 

 soil. Use a thermometer or observe the early growth of 

 plants on both drained and undrained places.

CHAPTER VIII. SOIL IMPROVEMENT. 



1. Study the different types of plows, harrows, culti-
