58 VINES 
In this way you can winter plants that are con- 
sidered, by some people, tropical. Such gems as 
the Maréchal Neil rose and the sweet-scented 
jasmine (Jasminum officinale) can be grown out- 
side as hardy vines; and surely, either one of these 
plants would pay for the labour involved. 
Plants so situated, on the south side of a build- 
ing for example, as to be in a continual drip in 
winter will sometimes get killed back. The 
winter-killing in this case is quite out of the ordi- 
nary. The drip during the day covers the vine 
with water; this freezes and forms a coating of 
ice on the vine which becomes very heavy; 
then, perchance, the wind springs up shaking 
the vine considerably, and causing some of the 
stems to crack. The only preventive is covering 
the plants to protect them from the drip, the 
best way in each case being easily determined 
according to the local conditions. 
Animals often cause trouble with various kinds 
of vines in winter, but not more so with vines 
than with other plants. Ground moles will some- 
times destroy the roots; but it is not only their 
eating of the roots that causes trouble, but also 
the fact that they sometimes loosen the soil about 
the roots, causing them to dry out, and the vine, 
perhaps, to die. Whenever you see a ground
