In the landscaping photo on this page, the concept is similar, but the execution -- and results -- are different. Here, the split-rail style is used. More importantly, there's no mortar showing where the rails meet the posts. Indeed, these masonry posts themselves betray not a bit of mortar anywhere. I think that gives this rustic fence a much nicer overall appearance than the one in the prior fence picture.
In the next fence picture, you'll see yet another variant on the post-and-rail style....
