subject matter which they follow, as well as a close 

 relation to farm life. Wherever appropriate at the 

 close of a chapter some experimental studies are 

 added. It is believed that the working- out of these ex- 

 ercises will enable the farmer's children to solve ordi- 

 nary practical problems arising on the farm, and pre- 

 pare for the more complex ones of experimental agri- 

 culture. 



It is hoped that the careful study of this book will 

 lead to a deeper interest in farm life, and to a more 

 careful and systematic study of the soils, crops, feeds, 

 fertilizers, and the like, by the children in the rural 

 schools and perhaps, incidentally, by the farmers 

 themselves. 



It is a wholesome indication of the trend of educa- 

 tional thought, that the legislatures of several states 

 have made compulsory the study of agriculture in the 

 district schools. 



We trust that this little book, by combining the 

 subjects of arithmetic and agriculture, will be of 

 material assistance to teachers in their efforts to do 

 effective work in both branches.
