Egypt (observations over seven years). 



Meteorological data from Meteorological Department, India. 



The above data are interesting. From Kearney we under- 

 stand that the fruits of the Deglet Noor ripen perfectly where 

 the heat units above 64F. between 1st May and 31st October 

 amount to 3,277 F. (vide Nefta), while Swingle states " From 

 three years' observations, it is considered that about 2,000C. 

 (3,600 F.) are required to ripen the Deglet Noor satisfactorily."
