den changes in temperature, and keep rain and snow from 

 them. Some buds are naked, others covered with hairs, others 

 with a kind of varnish or resin. Is this resin soluble in water ? 

 Find out which trees have two buds opposite each other, and 

 which ones have them arranged alternately. Some trees 

 have a bud terminating each branchlet; others, like the 

 elms, never show truly terminal buds. Study the arrange- 

 ment of buds on different trees, and verify or disprove the 

 statements made here. Each tree has its peculiar mode of 

 branching. Could you classify trees according to the soil 

 and locality where they most commonly grow ? Where do 

 willows and poplars generally grow? Where would you 

 expect to find maples and oaks ? 



The best time to plant trees is late in fall and early in 

 spring. The more roots can be left on the tree, the more 

 likely it is to grow. The branches should be trimmed, but 

 should not be cut away entirely. Most of our trees can 

 easily be raised from seeds and many will grow from cut- 

 tings. You should try all these different ways of raising 

 trees, for that will teach you much which you cannot learn 

 in school.
