64 BITTER PIT INVESTIGATION. 



10. AT GOVERNMENT EXPERIMENT ORCHARD, SOUTH AUSTRALIA. 



In the pruning tests this season none of the apples were pitted. There were only a few fruits 

 on the various trees, and in some cases none at all, with the exception of Rome Beauty and Jonathan, 

 which produced a little more than the others. In 1913 there was only an odd fruit on some of the 

 trees, but in 1914 there was a considerable number. Jonathan, which had never been pruned after 

 the first year and the fruit not thinned, produced 163 apples free from Pit. Other varieties had only 

 one or two apples at the most pitted, so that the results as regards Pit will onlv be of value when the 

 trees are a little older. 



The continuation of these experiments will afford results of exceptional interest, because the 

 pruning work has been started on newly set trees, and the effects of particular methods of pruning 

 will be demonstrated for a series of years.
