144 ELEMENTS OF PLANT ANATOMY. 
Figure 64 represents solid sections of Conifer wood, show- 
ing its normal manner of growth. Number 1 is a triangular 
section from pith to rind showing ten years’ rings. The upper 
portion shows the rings, while the face view gives the appear- 
ance of the medullary rays as seen on a long radial section. 
Number 2 is an enlarged portion showing the anatomical 
characters of a single year’s growth. The medullary rays are 
here represented as being only a single cell in width, as seen 
on the cross-section and also on the tangential long section 
represented by the right-hand face view.
