 (Cal. Citropr., ' f (1919), No. 3, pp. 51, 65. 67, figs. 5).- Experiments were con- 

 ted ic tin' authors In smiie lemon orchards at Whlttler, Cal., to determine 

 the exad time required to damage young lemons at a given temperature and 

 \cn humidity. 



The results in general indicate that lemons are damaged more quickly by 

 low temperatures under humid conditions than under conditions of low 

 humidity. Small lemons will not he damaged hy a temperature Of 28° P. if 

 surrounded by a dry atmosphere, unless exposed Cor many hours. An nbun- 

 dance of moisture is nf value in protecting lemons from damage only when the 



condensation of atmospheric vapor into dew and the congealing of the dew 

 int.. ice liberates sufficient heat to hold the temperature above the freezing 



point of the fruit.
