Tales out of school
(1875)
“ Sugar and molasses are made from the juice of a cane; maple sugar from the sap of a tree that grows plentifully in all our mountain districts. You think it wonderful that milk can be taken from a tree. Is it not quite as strange to find sugar there? I suppose you will reply to this that the milk is ready prepared, while we have to make the sugar. That is true, but we add nothing to what we take from the tree. We simply apply heat to the sap, and behold the sugar! The chief reason, I think, why we are not surprised at this sugar tree is that we are familiar with it. ”
