"F. W.," Newark, Wayne Co., New York, writes: "On examining Acer plantanoides growing here as a street tree, I am surprised to find the young growth abounding in milky juice of the same appearance and consistency, thickening and turning dark on evaporation, and nearly as abundant as the common milk weed. I examined all our native maples, including Negundo, also Norway Maple, but find no traces of it. I would suppose anything of so specific character would be noticed, but in none of the botanical works to which I have access do I find it mentioned. On referring it to our county botanist he was not aware of it".

[The thick milky sap in the Norway Maple ought to be well known to the county botanist, for it is on record everywhere in European works relating to the Norway Maple. Kunth's "Synopsis," which every working botanist would want to possess, says, "Acer platanoides; Lactescens," etc. Don's " Dictionary " reads: " The leaves are seldom eaten or defaced by insects, because the tree abounds in a sharp milky juice disliked by them." We need not even go to European works. Darlington's "Flora Cestrica" or the plants of Chester County, Pennsylvania, says, "the leaves are lactescent - its milky juice prevents the ravages of insects." These books we quote simply because they are at hand.

We are glad our correspondent has called our attention to it, for it is one of the valuable facts in connection with the Norway Maple it is well not to forget. - Ed. G. M].
