PREFACE 
In preparing “Farm Animals,” the authors have sought 
to treat in detail, not merely the subjects of breeds, breed- 
ing, feeding, sanitation, medication and animal products, 
but to cover the whole field of animal industry. They 
have followed the general plan as developed in “Soils 
and Crops,” the initial and companion volume of this 
series. By means of the two books a full teachable course 
covering soils, crops and animals is now availabJe for 
use in the schools. Each of these books is complete in 
itself in its field. No collateral reading has been sug- 
gested for pupils, not because the authors wish to dis- 
courage such independent effort on the part of the pupil, 
but because they believe they have included as much sub- 
ject matter as can be covered wisely in 16 weeks by 
pupils of high school age. 
In the preparation of the subject matter, the attempt 
has been made to adapt it to the high school mind; that is, 
to pupils between the ages of 14 and 18. It has been 
assumed that this book, like “Soils and Crops,” will oc- 
cupy 16 full weeks of three recitations each, and that two 
days each week would be devoted to practicums, or one 
day to practicums and one day to review of the work 
of the previous three days. The practicums selected are 
all possible for high school use. The method of con- 
ducting them is clearly explained, and the large number 
provided will enable the teacher to select such as are best 
adapted to the school and circumstances. It is particu- 
larly desirable that considerable time be used for scoring 
and judging work in order that the student may be made 
fully acquainted with the good and bad points of each 
class of animals.
