1. Find the number of pounds of butter in 1200 pounds of milk that tests 3 per cent of butter-fat.
2. A cow yields 4800 pounds of milk in a year. Her milk tests 4 per cent of butter-fat. Find the total amount of butter-fat she yields. Find also the total amount of butter.
3. The milk of two cows was tested: one yielded in a year 6000 pounds of milk that tested 3 per cent of fat; the other yielded 5000 pounds that tested 4 per cent. Which cow yielded the more butter-fat? What was the money value of the butter produced by each if butter-fat is worth twenty-five cents a pound?
SECTION LXIV. GROWING FEED STUFFS ON THE FARM
Economy in raising live stock demands the production of all "roughness" or roughage materials on the farm. By roughness, or roughage, of course you understand that bulky food, like hay, grass, clover, stover, etc., is meant. It is possible to purchase all roughage materials and yet make a financial success of growing farm animals, but this certainly is not the surest way to succeed. Every farm should raise all its feed stuffs. In deciding what forage and grain crops to grow we should decide:
1. The crops best suited to our soil and climate. 2. The crops best suited to our line of business. 3. The crops that will give us the most protein. 4. The crops that produce the most. 5. The crops that will keep our soil in the best condition.
1. _The crops best suited to our soil and climate._ Farm crops, as every child of the farm knows, are not equally adapted to all soils and climates. Cotton cannot be produced where the climate is cool and the seasons short. Timothy and blue grass are most productive on cool, limestone soils. Cowpeas demand warm, dry soils. But in spite of climatic limitations, Nature has been generous in the wide variety of forage she has given us.
Our aim should be to make the best use of what we have, to improve by selection and care those kinds best adapted to our soil and climate, and to secure, by better methods of growing and curing, the greatest yields at the least possible cost.
2. _The crops best suited to our line of business._ A farmer necessarily becomes more or less of a specialist; he gathers those kinds of live stock about him which he likes best and which he finds the most profitable. He should, on his farm, select for his main crops those that he can grow with the greatest pleasure and with the greatest profit.
