WITH PLATE XL, 
Rootstocks penetrating the ground vertically. 
Every one knows how tetheground. The minute 
irminal rootlets find hese way i crevices between the par- 
a “es forming the earth, and the increasing bulk of the root 
*hes these particles aside. It is different with a rootstock. 
existence on germination begins near the surface of the 
ground and if it Ses the ground vertically it must pen- 
ttrate it backwa 
here plants; ae in marshy soil, as in the case of ieee 
4S foetidus, this is readily understood, but when t : 
und is more compact it is quite another matter.
