as we wish to throw sap to the buds. After the buds are well started 

 the old twigs may be gradually removed. One or two years after 

 budding the young trees are ready to >set in the orchard. 



Large trees may be budded if a change of variety or if a better tree 

 is desired. Here the buds are inserted into the branches (Figs. 11 

 and 12), some of which are permitted to remain to insure thrift, and 

 removed as the new growths from the bud become large and thrifty. 

 The trunks in this case should be protected from the sun's hot rays by 

 whitewash, or by wrapping with some protecting cover. It is also well

 In case Fuller's rose weevil attacks the buds, as they are wont to do, 

 the insects may be headed off by winding loose cotton about the trunk 

 below the bud. The beetles are wingless, and so can reach the buds 

 only by crawling up the trunk. The cotton will prevent this. 



Citrus trees can be started by grafting, by slips, or by layering, but 

 as none of these methods are now in vogue in our citrus orchards it is 

 needless to discuss them here.
