The ? was asked how much sap does a tree produce? Every tree is different, some a little some a lot...I tapped this one big maple a couple of years ago and put two taps and two five gal buckets( what I use, a lady at a school supplies them) And the tree ran both buckets over two days running ,but that's not happened again.The most I have collected in a day this year has been about two gal some as little as a pint , and the little trees are running better than the big one. I cook mine out side on a fire in stoves I've made ,I have three stainless steel pans ,12 gal,24gal and a 60 gal,crude but they work.I'ts hard for me to imagine how the Indians could ever produce syrup... I have a neighbor that moved next door to me that has ten kids and I've got them interested ,I supply the trees and all supplies and they supply the labor ,a good deal for both I guess, We cooked off eighteen quarts Thur. and Fri. Had a big mess of waffles and syrup this morning.
