 he should also know the trees when he sees them. 



We are indebted to the trees for many things besides 

 wood. They give us delightful shade and coolness in 

 summer ; many of them produce delicious fruit and 

 nuts ; from them we obtain such valuable products as 

 maple sirup and sugar; while tar, pitch, turpentine, 

 rubber, and tannin are only a few of the many tree pro- 

 ducts. The houses we live in, the chairs we sit on, in 

 fact, most of our furniture, even to the frames of our 

 pictures, the cars we ride in, and the very pencils we 

 write with, are of wood which was once part of the 

 living forest.
