each year; while others clear fifty dollars or more a year from 

 each cow above the cost of feed and labor. 



Farmer "A" will be deluded by the false belief that the 

 creamery separators will kill germs of tuberculosis and thus 

 prevent that disease from spreading from one herd to others 

 in the neighborhood. "B" will investigate the matter, and 

 if neighboring cattle are thought to have the disease 

 he will promptly stop taking skim milk from the butter 

 factory. He will retain his own herd's pure skim milk on his 

 place and sell cream only. 



System in Farming. In all parts of the country farmers 

 need to put more business and system into their farming. 

 Too little system is the chief cause of failure in many in- 

 stances. On farms that are successful more system could be 

 introduced with profit. No other calling of man could with- 

 stand the lack of system which is often found in farming. 



Mapping the Farm. Begin by mapping out the farm. 

 It is not necessary to employ a surveyor. First make a rough 

 sketch of the outline of the fields as they now exist. State 

 the area of each field or division as nearly as possible. With 

 this sketch as a basis to work from, then measure the real 

 length of each line represented on the chart. A man and 

 a boy with a tape line fifty or one hundred feet long will 

 be able to measure all the lines in a few hours. Write the 

 lengths on the chart. 



Now you are ready make a corrected map. With a foot 

 rule or yard measure, a large sheet of paper and a pencil, you 

 can make a map with true proportions very easily. Previous 

 work in map drawing will aid in getting directions of lines. 

 Of course a scale must be established, say one inch on the map 

 to five hundred feet on the land. After the map is drawn 

 it will be easier to calculate the true area of each field. 



Planning the Crops. On each division or field we should 

 next write the name of the crop or crops which that field 

 produced last year, as "Oats followed by clover." Then
