steve,
yeah, I don't quite buy the hole in the brick being meant for
ventilation, yes on saving weight and a little bit on raw materials
and the few times I worked on a brick line (never got past lunchtime) I
got the impression the intention was for the mortar to go in the holes
for additional holding
no way in Hades anyone gonna lay a brick w/out getting mortar in the holes
