In selecting seeds for nursery stock the following 

 points should be considered. The soil on which the grove 

 is to be located, and the variety of fruit to be grown. 

 All of the different species and varieties of the citrus 

 family can be budded one on to another, but some suc- 

 ceed better on one stock than on another. The same 

 is true of soil, ail kinds of citrus trees may grow 

 on any particular soil, but on account of different root 

 .systems and different feeding habits, some are much bet- 

 ter adapted to certain soils than others. 



The Sour Orange seems to be more universally adapted 

 than the rough lemon, the grapefruit, etc., but it is less 

 vigorous than these, and in light soil the growth is often 

 .slow for commercial purposes. During the first few years 

 the sour orange makes a slower growth than the rough 

 lemon, grapefruit or shaddock, even on heavy or medium 

 heavy soil, but after the root system becomes well devel- 

 oped, the difference is not very great. The root system 

 is deep, for which reason it is often recommended for 

 dry soil, which is quite right, provided the soil water 

 is not too far down, but even if the tree can reach water 

 when it becomes old enough, it should be well remem- 

 bered that moisture close to the surface is necessary dur- 

 ing the first few years. Where the sour orange can be 

 especially recommended is on heavy moist land, because 

 it is less subject to gumming than the other stocks. 



The sour orange is a good stock for the grapefruit 

 and the common orange, although it can not be recom- 

 mended for the navel. Neither should if "be used for 

 satsuma nor kumquat. 



The Rough Lemon is more vigorous than the sour 

 orange and is especially desirable for light soil poor in
