plant food. It should never be planted on moist land, 

 because it is very much subject to gumming. The root 

 system is shallow and in some soils the tap root is entirely 

 absent. 



The rough lemon is suitable as a budding stock for any 

 of the commercial citrus fruits. It induces early bearing 

 because of its vigour, but the first couple of crops of fruit 

 are usually large, coarse and juiceless. It produces a 

 larger tree of any variety 'budded on to it, than does the 

 sour orange during the first 4 to 5 years, but later there 

 is almost no difference in size, unless the soil is very 

 poor. The rough lemon is especially well suited as a 

 stock on which to bud King, Tangerine and Kumquat 

 varieties. When grapefruit and orange varieties are bud-

 gumming on heavy soil. 



The Grapefruit and the Shaddock are very good bud- 

 ding stocks, the shaddock especially being very vigorous. 

 The root system is deeper than that of the rough lemon, 

 and it is suitable for the same class of soil as that. It is 

 not much more subject to gumming than the sour orange, 

 and less so than the rough leinnon, and as it is suitable 

 as a stock for all kinds of citrus fruits it is worthy of 

 general use. 



Commercial Varieties of Oranges as advertised in nur- 

 sery catalogues are almost legion and practically all of 

 them have been planted in the West Indies, the names 

 are still retained but there is considerable variation, 

 which is however of minor practical Importance. The

 quality and appearance is. The most desirable size is
