PREFACE 



FIRST YEAR SCIENCE deals with the earth and the sun in 

 their relations to man. This treatment has three advantages : 

 it gives the book unity ; it gives practical interest ; and it offers 

 all the earth science needed to meet such requirements as those 

 of the College Entrance Examination Board. 



The book is meant for immature students. For this reason the 

 language is simple, not technical, and the principles are thor- 

 oughly illustrated by experiments and pictures. A treatment 

 too' terse and condensed tends to confuse young students; 

 hence the topics in First Year Science are sufficiently discussed 

 to enable young pupils to master them with ease. 



All subjects of elementary school science physics, chemis- 

 try, meteorology, botany, zoology, physiology, astronomy, 

 physiography, forestry, and agriculture are treated, so that 

 the pupil can find out for himself which ones he wishes to study 

 later in the course. 



The book is complete in itself; no reference library, no 

 manual, is needed. The experiments require only the simplest 

 apparatus. In most cases the mere reading of them is sufficient 

 to illustrate the text. 



The separate chapters, while forming links in the develop- 

 ment of the whole subject, are in most cases separate units, 

 any one of which may be omitted when time for it is lacking. 

 Each chapter closes with a pithy summary and suggestive 

 questions. 



The book deals with the large and concrete things which 

 surround boys and girls and in which they are naturally in- 

 terested. There is little abstract theory, the effort being to 

 call attention to things that can be seen and appreciated.
