BITTER PIT INVESTIGATION. 



Amount of Juice. If an attempt is made to arrange the varieties in the order of their amount 

 of juice, it is found that in each district there is a different arrangement. In the Bathurst district 

 the Cleopatra has the most, and the Yates the least, while in the other two districts the Yates some- 

 times contains more juice than the Cleopatra. 



So definite analysis does not support the view that the amount of juice in the apple and Bitter 

 Pit are necessarily associated. 



Ash. If the same method is followed with the amount of ash in the juice, there is no con- 

 stancy in the arrangement. 



Acidity. The greater amount of acidity does not seem to have any bearing on the liability 

 to Pit, as in each of the districts Cleopatra and Yates have the smallest amount. 



Cane-Sugar Content. Sucrose or cane-sugar is found to be greatest in all the districts in 

 Dunn's Favourite, and least in Stone Pippin, so that a wide difference in sugar-content does not 

 seem to have any relation to pitting. Besides, Cleopatra and Yates come together when the varieties 

 are arranged in the order of their sugar-content. 



Lime in Ash of Juice. There is sometimes very little difference in the amount of lime present 

 in liable and non-liable varieties, but in all the districts the half-grown Yates contains a slightly 

 greater amount than Cleopatra.
