I bought a book 'Turning Green Wood' by Michael O'Donnell. In it he explains
reaction wood in branches, he says:

"Hardwood in the northern hemisphere build the reation wood on the tension
side of the pith, which gives rise to growth rings in branches being wider
on the tension side (the upper side) than on the compression side. In the
southern hemisphere this is reversed."

I vaguely recall that Hoadley says something similar but it was
concerning hardwood v softwood rather than hemispheres. Too late to
look it up at the moment. That ring a bell w/anyone?
