8. Have an aquarium. A glass vessel or a 

 Mason fruit-jar, with water frequently renewed, 

 will serve for a time. Have some water-plants 

 growing in the aquarium and keep a few fishes, 

 salamanders and tadpoles for study. 



9. Have a museum of things related to the 

 life and affairs of the region. Let the collec- 

 tion be started and increased by the children 

 themselves. It is suggested that collections be 

 made of the following: 



(a) The different types of soil found in 

 the neighborhood: sand, silt, clay, muck, and 

 sandy, silty and clay loams. 



(b) Seeds of common vegetables, flowers, 

 fruits, and trees. 



(c) Common grasses: timothy, red-top, 

 meadow fescue, Kentucky blue-grass orchard- 

 grass. 



(d) Common legumes of the farm and 

 garden : red, white, and alsike clovers, alfalfa, 

 peas, beans, vetch, soy beans, cowpeas.
