Mark just sent me an email asking about chinking, insulation, boric acid and preservatives for a log barn project he is working on.

Hello Mark and thanks for the question!
I’m going to stick my neck out and assume that the logs on the barn are hand hewn. With that in mind you may want to check out the section on Hand Hewn Chinking for starters.
