112 NATURAL HISTORY OF THE FARM 



The record of this study will be in two parts: 



1 . The student will write up brief notes on the dog, horse, 

 cow, sheep, pig, etc., concerning those points in their natural 

 history determining their availability for purposes of domesti- 

 cation as follows: their size and weight (average); rate of 

 growth; reproductive capacity; foods and feeding habits; 

 voice and social habits; weapons and fighting habits; for 

 what use fit; and general attractiveness or unattractiveness 

 of make-up and behavior. These notes should include only 

 personal observations. 



2. The record of the second part of this study, the com- 

 parison of breeds, may conveniently be incorporated into 

 tables, one for each species studied, with column headings 

 indicating the more obvious points of structure and of pro- 

 ductiveness and habits in which the breeds differ from one 

 another. For example, a table for the breeds of cattle might 

 have the column headings as follows: 



Name of breed (as Holstein, Ayrshire, etc.) 



Average weight (adult) 



Average milk production (get data from dairy record). 



Color and markings. 



Horns. 



Muzzle. 



Feet.
