We have gathered together today, in a still-dark grove on the side of a hill, to hear a few words about hemlock. We are a small group and there are not many words. Nothing anyone can say can possibly sum up the long life of hemlock on the eastern seaboard of North America, which began about 30 million years ago and includes a long stretch of time that runs from the early Pleistocene era, as the glaciers came and went, up until the arrival from East Asia of a tiny sap-sucking bug, the hemlock woolly adelgid, which landed in the United States around the time Calvin Coolidge made it into office...

Indeed, for many Russians, a victorious reclamation of the Black Sea peninsula—whether by means of Tuesday's treaty or by violence—would help bury the ghosts of an ill-conceived, disorganized and festering 19th-century conflict that has made Crimea, for Russians, practically synonymous with disaster...
