rot, impa/.ient of much moisture around the roots, 

 and more likely to suffer from the attacks of alkalies 

 than the other two. 



Therefore, trees on this stock should not be planted 

 on soil likely to be flooded by rain or irrigation water ; 

 but will succeed on dry situations having good 

 drainage. 



Bough lemon stock is the favorite stock for citrus 

 trees at present used in Sydney, having practically 

 superseded the Seville and sweet orange for that 

 purpose, and is there known as the "Citronella" 

 stock. This variety has also been extensively used 

 as a citrus stock along the Murray Valley, and so 

 far has given good results. 



The rough lemon stock gives rise to a tall, vigorous 

 tree, with large sized fruit, and trees budded upon it 

 grow very quickly and come early into bearing. 



In the writer's plantation Washington Navel trees, 

 budded upon sweet orange and lemon stock, were 

 planted side by side at the same time, and in the same 

 class of soil, and at the present time (eight years 

 after planting) not only have the trees on the lemon 

 stock beaten the others in fruitfulness, but in 

 quality of fruit size, thinness of rind, and sweet- 

 ness as well. However, this position may not 

 be maintained in the future, as the trees on the 

 orange stock steady down in growth and yield 

 heavier crops, but it bears out what appears to be 

 the general experience that the lemon stock .is 

 conducive to early fruiting. 



Briefly stated, sweet orange and rough lemon 

 stock may be safely used on dry situations having 

 loose soil and good drainage, while sour stock is best 

 suited to wet land, or land likely to ba flo Deled.
