EXPLANATIONS AND SUGGESTIONS XV 



United States Department of Agriculture and also from the Agri- 

 cultural Colleges. 



Early plants — where to grow them. — It is not feasible or even 

 possible for all pupils to grow their own plants at their homes. In 

 many schools, it is probably best to make hotbeds and cold frames 

 at the school, under the direction of an instructor who will also 

 supervise the growing of the plants. Each pupil can have whatever 

 space is needed and then the plants may be taken to the homes and 

 set out at the proper time. There are many arguments in favor of 

 this plan. 



A special explanation. — In Root Crop Project XII, there is 

 almost an entire absence of references, except cross references 

 in this volume. This is due to the fact that there are so many 

 root crops that a multiplicity of references would be necessary to 

 cover the entire field. Pupils will readily find the information de- 

 sired in references C, L, and W-VG (see Reference Key), and 

 in the numerous bulletins that are available. The same may be 

 said of Project XXI, Making the Home Garden. 



How to use this book. — This book is intended to serve as a 

 guide in studying and conducting vegetable gardening projects. 

 The mind of the pupil should be concentrated on the thing to be 

 accomplished. All effort in seeking information should be cen- 

 tered, for the time being, on this one thing. In no instance should 

 the chapter be studied as chapters are usually studied. The sec- 

 tions, indicated by numbers, are natural divisions of the projects 

 and each section raises a number of questions that should be an- 

 swered before proceeding with that part of the project. 



Only the most salient poin,ts are discussed in this book and it is 

 expected that students will make free use of the vast amount of 

 literature relating to vegetable gardening.
