Unless where the trees were irrigated, the apples were below the normal size, and this may be 

 accounted for by the relatively low rainfall during November, December, and January. Most of the 

 rain in January fell towards the end of the month, beginning on the 28th, so that there was continuous 

 dry weather for the space of three months. The fruit never really recovered from the check it received 

 during these dry months, so that the apples, although abundant, were smaller in size. 



The fruit was picked on 10th April, with the result shown in the following table :
