Changes which take place in the Field 



passing, varies a good deal with the state of the atmosphere. In 

 the same rick, I found one-year-old clover-hay to contain from 

 18*20 per cent, of moisture in the colder and damper months of 

 the year, and only 14*15 per cent, in the drier months. Clover- 

 hay, therefore, may be assumed to contain on an average about 

 one-sixth of its weight of water.
