NEW CREATIONS IN PLANT LIFE 
for blending with a plant long accustomed 
to the warmer portions of the temperate zone. 
Then, by uniting this arctic plant with the 
temperate zone plant, I reach a plant which is 
of the right frost resistance to be grown in the 
colder parts of the temperate zones, and thus 
are made possible these frost-resisting fruit trees 
which will bear stiff freezing without harm. 
Another plant may be troubled with cold, wet 
feet—it needs hardening so that it will grow 
satisfactorily in a soil that may be wet. So it 
must be bred against this. One of the arctic 
plants, for example, which has never grown in 
the temperate zone may be a very desirable 
plant to introduce, but it has never been used 
to a warm, early spring and it begins its 
budding and blossoming so early that it fails to 
accomplish what it should in fruit or flower 
productions. So it is necessary to breed it in 
turn to temperate climate conditions. 
“Cross a hardy plant and a tender plant 
and often the tendency is toward the hardy; 
the waves, so to speak, sweep ever up toward 
the hardy, to the highest limits of the hardy, 
and some few sweep up over;—it is these few 
we must catch and make use of, for, on an
