kinds of weather. They are not intended to give all the in- 

 formation demanded of the student. This is to be acquired at 

 first hand. They are merely suggestive, serving to direct the 

 student's powers of observation and to give coherence to the 

 knowledge he obtains in the field. At the close of each chapter 

 a definite programme of work is given, including suggestions for 

 recording observations by means of notes, diagrams, etc. There 

 is also included a number of optional exercises for the individ- 

 ual student, to.be pursued independently. 



An idea of the character of the studies may be obtained by 

 glancing at the table of contents. In Part I we find such titles 

 as " The wild fruits of the farm," " The farm stream," The 

 November seed crop," The wild mammals of the farm," etc.; 

 in Part II, "The lay of the land," ' Winter activities of wild 

 animals," ' Fiber products of the farm," The fence-row"; and 

 in Part III, " The progress of the seasons," " The clovers," 

 Some insects at work on farm crops," ' Insects molesting farm 

 animals," Our in the rain," " The population of an old apple- 

 tree," etc. 



As several of these titles suggest, there are many references 

 to insects and their ways. These are, for the most part, necess- 

 arily of a very general character, but mention may be made of a 

 useful table for the recognition of aquatic insects in the immature 

 stages, given in connection with the study of "The farm stream". 



The book is illustrated by numerous well-chosen cuts, which 

 with a few exceptions, are accurate and effective. It should be 

 in the hands of every teacher of Nature Study.
