unharmed. This indication of the destructive agency of the cold 
winds was not in other cases so clearly shown. 
In some instances terminal twigs of hemlocks, Abies Canadensis, 
had their leaves brown and discolored as if winter-killed, but the 
twigs themselves retained their vitality and in June had commenced 
to put forth new shoots as if nothing had happened. Grape-vines 
supposed dead, in some cases sprouted at or near the roots and sent 
up new shoots which grew with unparalleled vigor.
