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.
