OTHER STUDIES. 



What can yon find out about the evolution of the to- 

 mato? In our grandmothers' days they were grown as 

 garden curiosities and commonly considered poisonous. 

 Bailey's ''Lessons With Plants" will give you an account 

 of the changes cultivation has made in tomatoes. 



As onions, potatoes, and radishes develop why not 

 think of them in some other connection than as merely 

 furnishing food material for us ? Take up a study of the 

 character of their growth first. Would potatoes, radishes 

 and onions all be called tubers ? If an onion isn't a tuber, 

 what is it? Radishes are called crown tubers, as are all 

 tubers which produce leaves and stems at the upper end 

 and roots below. What crown tubers can you find in the 

 home garden or in the market? Is there any diflPerence 

 in the tubers of Irish and sweet potatoes? 



After you are familiar with the different kinds of 

 thickened stems and roots, ask yourselves if they serve 

 the plant in any way. An old potato left in the cellar 

 will sprout and the potato itself wither away. What did 

 the sprout feed upon to give it such a start ? What do 

 tiny bean and other plants feed upon before they get 

 firmly fixed in the soil? May not tubers, bulbs, seeds, 

 etc., be storehouses for plant food? Talk this over. Also 

 their use in propagating new plants of the same kind. 

 How many things that garden has given us to see and 

 think about, and yet the work suggested is only a begin- 

 ning of it all. One pair of eager eyes will see more 

 things to wonder about than many a busy brain could 

 answer. Gro out in the garden and learn to see, learn to
