The lettuce has shown no veiy marked deviation from the controls, 

 save the seeds from the packages kept at Mo))ile, and those which were 

 stored in })asements in envelopes at Baton Rouge and Lake City. 

 The average results of the second series of tests show a similar losss in 

 vitality of all of the seeds from the envelopes. The samples of seed from 

 the bottles germinated practicall}" as well as the controls. The results 

 of the first series of tests are not entirely satisfactory, none of the 

 tests having gone to standard. The low germination of the lettuce in 

 this series was due to inability to properly control the temperature in 

 the germinating pans. The proper temperature for the successful 

 germination of lettuce seed is 20° C, while in this first series the ger- 

 mination tests were unavoidably made at 26° to 27.5° C. Neverthe- 

 less, this seeming objection is of little consequence, since all of the 

 results are directly comparable with the control.
