160 Lessons in Nature Study. 



until any one is tired. It is often very handy to have one 

 of the boys take a hammer for breaking stones. 



Do not forget that the mere collection of materials is not 

 the end and aim of the trip. It is to bring pupils in contact 

 with nature, and so cultivate the heart. This is one great 

 end of nature study. When the materials collected on this 

 walk have been used, there is an excuse to warrant another 

 " hunt." 



OF THE SECOND WALK IN SPRING. 

 Lessons on Materials Found. 



I. Young Maple. 



Here are some maple-keys that we found sprouting 

 yesterday. How many leaves has it ? Are they like com- 

 mon maple-leaves ? 



Hattie. They are long and slim. 



Joste. They are bent and twisted. 



Teacher. Yes, these leaves were rolled up and folded in 

 the seed. Now they are straightened out. Has any one a 

 little maple with more than the first two leaves ? 



Anna. My maple has four leaves. The second leaves 

 are wider. 



Willie. The second leaves are more like real maple- 

 leaves. 



Teacher. Yes, the second leaves are wide, and the third 

 pair are like large leaves. Are the leaves opposite or alter- 

 nate ? 



Hattie. They are opposite. 



In like manner study all the young seedlings collected. 

 The first and second beech-leaves are opposite, later 

 ones alternate. The young pine-leaves are in a whorl. The 

 young oak-leaves alternate from the first. Parts of the seed 

 come up in some plants (beech, bean, maple, etc.). In other 

 plants the seed remains on the earth (pea, acorn, horse- 

 chestnut).
