This is a simple and convenient system but it is adaptable to further 

 simplification and modification. Where alfalfa is not available, the other 

 two crops, amber cane and oats and Canadian field peas, can be made to last 

 throughout the season. In some cases it will also be possible to cut down 

 the number of sowings of these crops and make larger plots. Four is the 

 smallest number of sowings that can be expected to give good results and 

 five or six are better as they insure a more uniform supply of green feed 

 throughout the season. This is due to the minimizing of the risk of too 

 early maturing of the crops with subsequent unsuitability of the feed for 

 soiling. Sweet clover can also be used in place of the alfalfa where it is 

 available. 



SYSTEM B. 



In this system winter rye is depended on for the earliest soiling, while 

 barley replaces oats in the mixture with Canadian field peas and the millet 

 takes the place of the last sowing of amber cane used in the previous 

 system. For the reasons pointed out in the section on individual crops 

 this is not quite so suitable as the first system and it is also less easily 

 varied and adapted to individual conditions.
