In the butter tests conducted by the same Association, 

 the prizes are awarded according to the following scale of 

 points : One point for every ounce of butter ; one point for 

 every completed ten days since calving, deducting the first 

 forty days. Maximum allowance for period of lactation, 

 12 points. Fractions of ounces of butter, and incomplete

 same number of points, the prize is awarded to the cow that 

 has been the longest time in milk.

 Each cow requires, besides summer pasture, 2 tons of straw
