these experiments, together with those on alfalfa and rowen, 

 are now in press. 



Forage crop observations are continued from year to year. 

 Observations with sweet clover and Sudan grass confirmed 

 previous conclusions. We succeeded the past year in getting a 

 second growth of sweet clover by cutting just before the first 

 growth began to bud. The second growth failed for two pre- 

 ceding years, possibly because the first cutting was delayed 

 a little too long. We fail to see any use for this crop except 

 as a soil renovator. One crop yearly is about all that can 

 be secured. Sudan grass proves an addition to our list of 

 green crops, but the writer fails to see any distinct advantage 

 to it over barnyard millet. It needs hot weather for its de- 

 velopment, and the seed which has been purchased of the most 

 reliable dealers has not proved very satisfactory. A rather 

 better second crop can be secured than with barnyard millet 

 if the months of July and August are quite warm.
