EXPERIMENT STATION BULLETINS. 429 



When individual farms are studied a considerable range of investment 

 per cow is noted. This is occasioned by the kind and conditions of the 

 cows; the number, age, and state of repairs of the buildings; and the 

 amount, and condition of the other equipment. 



Table VI which follows, gives the taxes, interest, insurance, and de- 

 preciation on the cattle, buildings, and other equipment on each of the 

 farms for each year. It also gives in its summary the general per cow 

 average for each of these items. A rather marked variation is noticed 

 in these items when the individual farms are compared. Since these 

 farms were not all of the same class a considerable range is inevitable. 



When a comparison is made between the general average for the two 

 years a more stable condition is observed.
