will the circumstances be in which it is growing. As we have 

 already seen, the complete root-system of the vine consists of tap- 

 roots and laterals. If either of these develop themselves exclusively 

 at the expense of the others the vine will not thrive. A long cutting 

 produces a crown of lateral roots at each knot, and no tap-roots; it 

 is thus very differently situated from that produced by a short cutting, 

 which is much more similar to a seedling vine, 



Fig. 13 represents the vine resulting from a short cutting, Fig. 14 

 that resulting from a very long one.

Although vine roots must penetrate deeply into the soil, their 

 junction with the stem should be as near the surface as possible. 



So great is the advantage of short cuttings over 

 long ones that it has been recommended by many 

 authorities to plant what are termed single-eye 

 cuttings (Fig. 15). 



These are sown in drills like seeds, and covered with 

 an inch or so of soil. They give excellent results, and FIG. 15. 

 are of great value for reproducing rare sorts, as every eye will, 

 under favorable circumstances, give rise to a plant. Some of the 

 American sorts, which do not as a rule strike easily, are propagated
