forms of trees are so completely under our control when 

 we possess the requisite knowledge of the character and 

 modes of vegetation of buds. 



2d, The Names and Characters of Buds. — All buds are 

 either, 1st, terminal., as when on the points of shoots (C, 

 fig. 20) ; 2d, axillary, when situated in the angle made by 

 the projection of a leaf from the shoot or branch {A^ B, 

 fig. 20) ; 3d, adventitious or acidental, wiien originating 

 accident illy, as it were, or without any regularity, on the 

 older parts of trees, and not in the axil of a leaf They 

 are often produced by the breaking or cutting off of a 

 branch, or by a wound or incision made in the bark. In 

 the management of trained trees, special means are taken

to produce these buds on spaces of the trunk that it is de- 

 sirable to fill up. We sometimes see instances of such 

 buds on the stumps of old trees. 



The terminal and axillary buds produced on young 

 shoots, seem to have a different origin from these ac- 

 cidental buds — the former are connected with the pith of 

 the shoot, as we may see by dissecting them. On cutting 

 into a young shoot below a bud we find a cylinder of pith 

 entering into the bud from the pith of the shoot, but we 

 do not find this connection existing in the case of the 

 adventitious buds. 



Practically considered, buds are classified as follows •• —
