require a slower lateral movement and the co-operation of the 

 rnid-cells, on which account stinmli and v/ounding of the rind 

 often force the tree to put forth fruit-buds. The same purpose 

 is promoted by the constrained, horizontal, and bent jx)sition 

 of the branches. It is on this account that gardeners so ma- 

 nage their fruit-trees, as to remove the branches which rise 

 directly upwai'ds, and lead out into a fan-shape only those 

 that rise obliquely, that in this wav the tree mav be urged to 

 put out more fruit-buds.

 The idea is altogether false that wood-buds are produced 

 by the wood-circle, and fruit-buds by the pith or bark. 

 Every bud, as we have already said, arises from a reservoir, 

 which owes its origin to the generative sap. As this is the 

 product of the inner bark, all buds originate properly in 

 tlie inner-bark, and in so far as the wood also contains 

 inner-bark vessels, these may be considered as contributing 

 to the formation of buds. But we must more especially at- 

 tend to the connection of the buds \rith the inner-bark itself, 

 to understand particularly the success of the insertion of 

 buds, at the time when the rind is loosened from the inner- 

 bark, and the intervening space is full of generative sap, (293.)

Finally, the position of buds on the stem is worthy of 

 notice. Generally we find them either placed opposite to 

 each other, or alternating. If, however, we attend to the 

 series of their positions on the stem or branches, we frequent- 

 ly, at least, perceive a spiral line on which they are set. We 

 see in this case, again, the continually equalised and ever 

 renewed contest between the perpendicular and horizontal 

 direction. 



Buds plant their roots, which i'.re properly continuations of 

 the sap-vessels, between the inner-bark and the rind^ and 

 every bud ought to be considered as a new individual, which, 

 separated from its parent body, has the power of being pro- 

 pagated. Hence the art of the multiplication of trees. In
