David was on his way back from painting in Provincetown and I was happy he stopped for an overnight at my house. How to spend a lazy early-autumn Saturday? How about a walk through the Mount Auburn Cemetery? Criss-crossed with byways named Halcyon Avenue, Primrose Path (yes!) and Oxalis Path, this lovely spot of garden not far from Harvard Square provides the final resting places of Henry Wadsworth Longfellow, Winslow Homer, Isabella Stewart Gardner, Bernard Malamud, Buckminster Fuller, Mary Baker Eddy and several poets named Lowell, alongside many distinguished others with 19th-century names like Patience, Prudence and Joy. In the full-flush, last hurrah of its seasonal glory, the place never looked so radiant and overgrown as on this warm, late-September day. This simple waterlily pond, with all its shadows and reflections, looked to us like something an idle Impressionist might take a fancy to. We did.
