up, when we shall most likely find a condition something like that in Fig. 

 13. It will be seen that the marks E, C, B, are practically the same dis- 

 tance apart as before, and they are also the same distance from the peg AA. 

 The point of the root is no longer at DD, however, but has grown on to F. 

 The root, therefore, has grown almost wholly in the end portion. 



Now let us make a similar experiment with the stem or stalk. We Avill

mark a young stem, as at A in Fig. 14; but the next day we shall find that 

 these marks are farther apart than when we made them (B, Fig. 14). The 

 marks have all raised themselves above the ground as the plant has grown. 

 The stem, therefore, has grown between the joints rather than from the tip. 

 The stem usually grows most rapidly, at any given time, at the upper or 

 younger portion of the joint (or internode) ; and the joint soon reaches the 

 limit of its growth and becomes stationary, and a new one grows out above it. 



Natural science consists in two things, — seeing lohat you look at, and drawing 

 proper conclusions from what you see. 



Of course it will be understood that the idea of "nature study" did not 

 originate at Cornell University. Nature study has been the dream of the best 

 teachers for a century, and perhaps always, and of late years is made prominent 

 in all the best schools. Its value as a preparation for life on the farm is also 

 sufliciently obvious, and was pointed out long before Cornell University took 

 up the work. The credit due to Cornell University is that of being the first to 

 actually carry out the work on a great scale, and of putting U in forms so
