THIRD GRADE FALL WORK 141 



Find the percentage of water in various kinds of fruit 

 by weighing them before and after drying. 



What can you say of the power of pure sand or clay to 

 sustain vegetation ? Seeds do not grow in pure clay. There 

 are also fruit products that will not sustain mold. Sugar 

 is not a good soil for mold, and therefore fruit may be pre- 

 served in it by boiling the fruit in a rich sirup of sugar. 



If fruit that is canned or preserved begins to spoil, it should 

 be heated at once. This kills the spores if there be any, 

 and at the same time arrests fermentation. 



LESSON XIV 

 SEED DISTRIBUTION FIELD LESSONS 



The study of fruits from the new point of their use to the 

 plant, naturally leads to the study of seed distribution in 

 general. Take the children out for a field lesson, where 

 they can see that in almost every place some kind of plant 

 may be found growing. 



Also, if possible, take the pupils to some near-by farm and 

 let them see how man takes care of the seeds he raises ; how 

 he plants them; and how, by furnishing better conditions 

 than nature does, he gets better results. 



They should see the stacks of hay and grain, the corn 

 shocks and granary, corncrib, fruit cellar, potato pit, etc., 

 and learn the use of each. They will discover that different 

 seeds require different care and treatment, and are planted 

 differently and at different times, according to the nature 

 and habits of the seeds and plants. After seeing how man 

 does this, they will more readily discover how nature does 

 it and the purpose in it.
