The attempts of the past age to fix the hardiness of plants by the thermometer are now admitted failures. Different seasons, though of the same temperature, affect differently different plants; but as the low temperature may be accompanied by moist air or dry air, high wind or a still atmosphere, a bright sky or a cloudy one, or even the character of the preceeding summer as regards heat or moisture. In this vicinity our lowest temperature was accompanied by a violent hurricane. Stiff close-growing trees suffered very little, but those with fine open foliage or loose branching habit were badly injured. Thus the Irish Yew, the thick close growing variety, kept as green as grass, while the usually hardier American is burnt as by tire. The Hemlock Spruce, Lawson Cypress and similar sprayey plants also suffered severely. The injury to these, with the comparative immunity of others that usually suffer, is one of the interesting experiences of the season.
