Treating Frozen Vines, 829 
vines began to recuperate. The right-hand spray 
shows a cluster of flowers appearing upon a_ belated 
shoot. Of course, only the clusters of the largest 
size, as shown at the left, ripened into good fruit. 
In proceeding to treat frozen vines, like those de- 
scribed, it must first of all be borne in mind that 
the injured parts are of no further use to the plants, 
and, as we have seen, they are very apt to weaken 
the plant by causing it to lose much of its moisture. 
The rational procedwe, therefore, is to strip off all 
the frozen shoots soon after the disaster, so as to 
allow the enervies of the plant to divert themselves 
to the production of new shoots. When the injured 
parts are soft and small, it is customary to remove 
them by pulling them off, rather than by cutting 
them .off. In vineyards which are well pruned, the 
cost of stripping ought not to exceed one dollar an acre. 
What is an injurious deyree of cold ?*—To this 
oft-asked question there can be no specific answer, 
because so much depends upon the latitude, the 
time of year and the condition of the plants. 
Hammon? gives the following “table of temperatures 
at which the following plants are liable to receive 
injury from frosts, compiled from information received 
from horticulturists, orchardists and gardeners through- 
out the entire Pacifie coast. 
“The temperatures given are as nearly as pos- 
sible those in contact with the plant. itself. 
* A discussion of acclimatization, and other problems of climate and plants, 
may be found in “The Survival of the Unlike.”
