52 QUINCE CULTURE. 
Trees received in the fall for spring planting can be 
kept in this way in good condition, and will be ready to 
plant earlier than where the planter waits till spring be- 
fore ordering them, because in the hurry of spring work 
some must necessarily wait. 
If trees are heeled-in in bundles, those inside are not 
pressed by the earth, and become dry. If the trees slope 
toward the south, they will not thaw out as soon in 
spring, as the tips shade the ground toward the sun. 
Heeling-in erect is only recommended where there is 
danger from mice. The place for heeling-in should be 
high enough to secure freedom from all danger of the 
trees becoming water-soaked. A sheltered situation is 
most desirable. 3

-'T'H8 best season to transplant is when the sap is compar- 
atively dormant, between the fall of the leaves in autumn 
and the development of the buds inspring. To decide in- 
telligently what is the best time to transplant we should, 
as far as possible, take into account the various agents 
that influence vegetation, such as the relative warmth of 
the soil and atmosphere, and the mildness or severity of 
the climate in winter. Then, again, the nature of the 
soil will be an important consideration, as also the facility 
for doing the work in the best manner. 
The greatest difference between the mean temperature 
of the earth and the air is in October, when the earth a foot 
below the surface is from a degree to a degree and a half
