Geo. V. N. Lotlirop, Eaq., of Detroit, has a letter about grapes iu the Uorticulturist for September, written under date of llth of Juue last. We extract as iollows : " Is the Adirondac grape hardy ?' This question was asked in your June numbor. Now, eousidering the high prioe we havo paid for this vine, as well I as the character aseribed to its fruit, this is a question of some impoitance. I will therefore report my experience. "My vine, then a year old, was set a year ago, started late but mado a growth of about three feet last year. It waf cixt back in November, auá earefuüy covered with two or three inches of earth. I unoovored it about the middle of April, and had no suspieion that it was injured, It proved, however, to be winter -lulled, root and Iraneh. "It should be stated that the extraordiuary weather of January last was very fatal to vegetable life. Many unprotected Catawaba and Isabella vines were killed to the ground, and even the Concord suffered severely. ïhoso which were covered escaped harra. "All my vinea were carfully covered with earth. And it may not be uninteresting to extend this note to a few other kinds. Union Village was killed ; Anna badly injiired ; Alen's Ilyhrid lost many buds, and starts slow ; Delaware, Diana, Rebecca, Creveling, Maxatawoey and lloger's Hybiid all canje through unhariaed."
