GARDENING of itself is of the greatest value 

 in the education of children, but it does not per- 

 form its complete function in the school unless 

 it has some organic connection with the other 

 work. It is nature study and illumines geogra- 

 phy. The soil is part of the earth's surface, de- 

 rived from the rocks granite, sandstone, lime- 

 stone, marble, shales and slates, which form the 

 earth's crust. Children very early get the idea 

 of the great interdependencies of animals, vege-

 nature's forces extremes and changes of tem-

The power of different soils to absorb and 

 retain heat and moisture; the relation of plants

 sun upon plant growth all this gives an experi-
