Some old images of log buildings in Warren County Mo.

 The Frederick Muench Farm, Dutzow Mo.

Note the laths near the door, there to hold the plaster. First time I have seen them put on in vertical pattern.
They are handmade laths or riven, split from a log.
Note also how they are 'woven' between the horizontal braces.
The weaving would mean no nails were needed.

 The same farm. You can see the door near the center of the photo.

They attached taller building could well have been log also.

 This is labeled 'Out building on the Frederick Muench Farm'.

Small log barn. The log holding up the outer edges of the roof are called 'cantilevered'.
