Crabtree Barns
The barn on the farm where I grew up.  It is constructed with solid oak
beams and framing.  The beams were held together with mortise and
tenion craftmanships with oak pins (see picture below).  It sat on a rock
foundation.  The barn had stanchions for dairy cows, several horse stalls,
a corn crib and two grain bins.  The hay loft was large.  To the left was a
pond, well, and windmill.  It is reported that ten acres of land with white
oak timber was purchased to construct the barn around the late 1800s.  
The barn was torn down in the early 1990s.
Right... the only remaining
artifact from the above barn
Above... our other barn.  It had
an open pit in the middle for
hay.  It has since been modified
to gain access to the middle.
