Arthur,
I realize that many will propose you need medical help if you mention felling with the moon. I even asked a college lecturer this, needless to say he just smiled. But here in the UK, the season for felling quality sycamore[similar to US maple] runs once the leavesturn brown and start to fall, until just before sap rising in spring, unfortunately with milder winters the sap can start to run a bit early, which is difficult especially if you have a very valuable large diameter veneer quality ripple sycamore which you need to fell but the sap is starting to rise, hence you fell when you know when the sap will be at its least even though the sap is rising. If you fell when in full sap, sycamore will not remain white after milling rather it will turn a light brown colour, hence the importance of felling when the sap is down. So comming back to the moon phases, if it is just another old tale, why is it that the few companies that specialise in very high value sycamore in the UK, follow the principle of moon phases especially at certain times of the year. So in reality why would I want to believe some college proffessor that has never cut very high value hardwoods when compared to companies which export considerable volums of quality logs. Old motto dont laugh at anything you dont understand AOM
