CITRUS TREES AND THEIR DISEASES 15 



only made his life study upon two varieties of trees, 

 namely ; the apple and the citrus, and as stated above 

 the sap of the citrus tree, and especially the orange, is 

 much heavier than that of the apple. To understand 

 thoroughly the difference between the two varieties of 

 trees, it is necessary to study the native home of both 

 varieties. 



DIFFERENCE IN THE VARIETIES OF TREES 



In their wild nature I have found that the citrus 

 tree originated in quite a different climate than 

 that of the apple. Therefore, the citrus tree in its 

 native climate does not become absolutely dormant at 

 any period of the year, but continues to drop and take 

 on new foliage at three different periods of the year, 

 thus widely differing from the apple. The citrus 

 tree has three ascensions and three descensions every 

 twelve months, nature intended that at certain periods 

 the citrus tree should rest to some extent while na- 

 ture hardened its wood growth. This, the writer 

 is satisfied, is not well understood by growers, and he 

 is ready to assert that too much water and too many 

 cultivations at this period does the tree an injustice, 

 not allowing it to properly harden and mature its wood, 

 therefore, forming an imperfect or a weak bud. This 

 important subject will be dealt with in this book later. 



BODY OF THE TREE 



Getting back to the body of the tree. Now the
