II2 NATURAL HISTORY OF THE FARM 
The record of this study will be in two parts: 
1. Thestudent 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.
