I just read the poem by van Dyke and find it heartwarming, filled with a musical beauty that needed expressing and was done well, I am sure there are better poems on the subject but there is nothing at all wrong with this one.
Must have rather simple tastes.
Today it seems fashionable to discard everything that's old, declaring it obsolete, worn out, over-the-hill, useless. What doesn't make too much sense though is the oft-encountered situation that the critics are usually unable to match the quality of the ones they are so eager to discard.
This poem was written with feeling and what it conveys to the reader justifies not cement boots in the Hudson River but a place among the Forget-Me-Nots.
