A correspondent at Ogdensburg, New York, is in trouble with the greenhouse. The leaves of the plants fall off, etc, etc, etc, etc. The pipes are painted by "some black material," and this tells the whole story. The predecessor of the present gardener could hardly have been a reader of the Gardener's Monthly or he would not have tarred the pipes - or indeed put anything on the pipes. If he left his situation for his bad success with his plants, he fully deserves his fate.
