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.
