Mr. Charles E. Parnell, of Queen's, Long Island, says:
" In this vicinity March proved very severe on the more tender evergreens. Euonymus japoni-cus and all its varieties are killed to the ground, and so are all hemlock spruce that were removed or transplanted last season. Irish yews, juniper, American and Siberian arborvitaes are severely injured, and many are dead."
The question of what influences the hardiness of plants becomes more intricate every year. It has become settled that it is not frost merely, but something else in conjunction therewith. Here in Germantown some hemlocks have badly suffered, and so has box edgings, small arborvitaes and some other things which usually stand a very low temperature, and yet at no time was the thermometer at zero. On the other hand, plants like the Euonymus japonicas and Mahonia aquifolia, which commonly suffer severely, have not lost a leaf, and are greener and fresher than we have ever known them. Libocedrus decurrens, which we have seen killed when growing near Thuja gigantea, and totally destroyed, while the latter has been unhurt, has the case reversed this season. The Libocedrus remains as green as grass, while it is the Thuja which is browned. It is frost with wind, frost with sun, frost with drying atmosphere, or frost on weak or frost on strong plants - or some other combination suiting some plants, which succeed, or not suiting some, which succumb; but just what, in each case, it seems very difficult to say. The only general result which is clear is, that no result as to what or what is not hardy can be given as a rule.
Because a plant once dies is no reason why we should not attempt it again.
