128 THE COW 



for the heifers and even for the calves. A round 

 silo thirty feet high and sixteen feet in diameter 

 if well filled will hold about 120 tons, and this 

 will be about what is required in our scheme of 

 dairy management. 



A good farmer ought to produce twelve tons of 

 silage to the acre on the average, so at least ten 

 acres of corn should be planted. This corn will 

 always be grown by plowing up ten acres of the 

 oldest and poorest meadow and it will always be 

 followed by oats. Our farm rotation map appears 

 about as follows : 



50 acres permanent pasture 



10 acres com 



10 acres oats 



30 acres hay 



The amount of com required is really the key 

 to the whole scheme. If a larger proportion of the 

 farm were tillable, we would have less pasture and 

 more crops. 



The ten acres of oats can hardly be expected to 

 yield more than 500 bushels and this will be far 

 above the average of the country, but fortunately 

 dairy farms generally yield more than average 

 crops. After we have fed the horses and poultry 

 and saved oats for seed, there will not be many left 

 for the cows. In other words, we must expect to 

 buy most of the grain feed. 



The thirty acres of hay (the ten acres of new 

 seeding being mostly clover) ought to give forty-
