Oh maths, it's all just numbers that signify amounts, the formula was correct, so offer an opinion rather than picking me up on not being able to do simple arithmetic.

This is the Internet after all, consider yourself fortunate that my grammer is passable and I've not mentioned coming to Ireland to give yer tombs a bit of swastika magic.

As to root balls being heavy. The three postholes in the carpark at Stonehenge (sounds classy?) are huge, ditto some of the others, so weight bizarrely doesn't appear to be a problem.

I was just wondering if each row was higher than the one in front, kinda ampitheatre stylee, but some of them really do have internal oval spaces, not dissimilar to the horse shoe at stone henge, which suggests that they might also have been higher at one end than the other.

"My" stone circle that has been excavated only has one post just inside the circle at the southern end. It was about one foot acorss and four feet deep. So, was it like a telegraph pole, or an alter, a podium, direction marker, upside down tree? a final vestige of the timber henges?

Tell me Fourwinds, you have your own website, you must know the answer.
