It is a good way to create rootstock of varieties which do not stool 
readily, such as Ottawa-3. Use seedling rootstock, graft pieces of 
Ottawa-3 to it, and bury the union deep.  The O-3 eventually sends 
out its own roots.  One can cut off the seedling root when one lifts 
the rootstock to line out, or just leave it.
