of collections under the belief that the pupils would thus learn 

 to know plants. It is not necessary to explain the shortcomings 

 of this method to any who have tried it. We all appreciate 

 the importance of having pupils know the common plants, but a 

 knowledge of the laws of plant growth and of the relations of 

 plant groups is of much greater importance than scientific 

 names. Collections should be made in the same manner as 

 experiments, i.e., with an objective. Collections illustrating 

 certain groups of plants or a certain number of groups, or of the 

 plants of a locality, or of the economic plants, or of the plants 

 used in certain industries may often be made with great profit. 

 Additional work for the bright and willing students is let 

 be encouraged. Pupils with a love for the work will do much 

 more than the requirements and are the real joy of the teacher.
