made a fair growth during March- This experience indicates 

 that Rhodes grass may survive a temperature of 17 F. if 

 abundance of moisture is present and the cold of only short 

 duration a week or so as was the case in 1917, while fre- 

 quent cold spells, when the soil is rather dry, are likely to 

 prove killing even when the temperature does not go much 

 below 25 F. A temperature of 26 F. is likely to kill the 

 plants to the roots, while a temperature of 32 F. is not likely 

 to damage the tops materially. 



SEED SAVING 



Seed has been gathered from our test plots from time to 

 time. This has been found to keep well and have a good germ-
