TEAILERS. See Creepers. 



TEAIN OIL. See Animal Matters. 



TEAINING has for its object the ren- 

 dering plants more productive either of 

 flowers or of fruit, by regulating the 

 number and position of their branches. 

 If their number be too great, they over- 

 shadow those below them, and by ex- 

 cluding the heat and light, prevent 

 that elaboration of the sap, required 

 for the production of fructification. If 

 they are too few, the sap is expended 

 in the production of more, and in ex- 

 tending the surface of the leaves re- 

 quired for the digestion of the juices. 



The position of the branches is im- 

 portant, because, if trained against a 

 wall, they obtain a higher temperature, 

 and protection from winds ; and if 

 trained with their points below the 

 horizontal, the return of the sap is 

 checked. Shy-flowering shrubs, as 

 Diplacus puniceus, are made to blossom 

 abundantly, and freely- flowering shrubs ,
