 The breadth of sapwood varies in genera, species, and 

 even in individuals ; in youth all species have sapwood only ; 

 many species are when older characterized by very narrow 

 sapwood : e.g., catalpa and sweet-chestnut with 1 2 zones of 

 sapwood, larch 1 2 c.m. of sapwood, so some oaks, yew, mul- 

 berry, robinia ; 10 c.m. and over, pines, hickory, elms, ash, etc. 

 It should also be noted that rapidity of growth is influential 

 on the ratio of sapwood to heartwood, in favour of the 

 former.
