Interesting to see this type of stacking - we tryed it back in the 80's in our wood yard. It does take time and you can't half stack alot of wood in a 'beehive' stack.
There's also a similat image here:

you'll need to open the images on the site.
Just remember to 'thatch' the top by making the top come to a conical point and turn the bark side up, on the logs, to deflect the rain down to the edge of the stack. Make sure you put down base bearers to allow air under the pile. There is also a cheat - make your circle of wood piling it higher and higher and then when you can't stack any more just throw logs into the middle until it comes to the top - you get less in but it does make it quicker to creat your pretty beehive.
So ends todays lecture.
