As soon as the first round or tier of logs is laid, the floor joists
should be set in place, notching them into the bottom side logs. If the
building has a continuous masonry foundation, the joists may be set on
top of it, as in a frame building.
In order that the ends of the joists may have sufficient bearing on the
wall, it is necessary either to notch the ends into the side logs or
hew the latter off on the inside. A simple method is to cut the notches
in the side logs before they are rolled into place. Pole joists should
be from 4 to 8 inches in diameter and hewed level on the upper side to
provide a solid bearing for nailing the flooring. Several different ways
of framing the floor joists are shown in figure 10.
