sects have been imprisoned showing difference between 

 extinct and extant species. 



The willow and sycamore are trees which grow best near 

 streams, and should be taken in connection with swamp 

 vegetation. The poplar and willow show marked differ-

 protection of buds and development' of catkins. 



In the early years of a child's school life most of the 

 work should be devoted to instilling into his soul an in- 

 terest and love for trees, but when he reaches the fifth grade 

 he should begin to appreciate their utility; the factor they 

 have been in civilization. Compare the characteristics of 

 different woods and their value for certain purposes. Why 

 should the wood of one tree be used for the mast and an- 

 other for the keel of a vessel that will weather the fiercest 

 gale, and of another the body of a violin whose vibrations 

 shall thrill the hearts of men. 



Relate great forest belts to regions of constant rainfall. 

 Compare growth of same trees under different conditions of 

 climate. 



Specimens of ebony, mahogany, bamboo, etc., should be 

 compared with pine, oak, etc. Relate to house furnishing

A love for trees should be engendered and a sentiment 

 against the great destruction of forests aroused. When 

 possible have trees planted, and others cared for by de- 

 stroying harmful insect life infesting trees. 



Some experiments can be made showing something of 

 the physiology of plants. Soane very valuable suggestions 

 may be found in "Botany" for June, in "Nature Study," by 

 W. S. Jackman.
