0. — We use the paraffin for Peach-trees at the rate of a wine-glassful to a 

 gallon of water. In applying it, one person is employed lifting a syringeful 

 out of the pot or pail and discharging it vigorously back again, while another 

 syringes the trees with it, and in a few minutes they are syringed with clean 

 water. This is done immediately after the trees are pruned and tied in win- 

 ter. We have not had to fumigate a Peach-tree this season for green-fly, and 

 last spring the only trees out of many that were not affected with fly, were 

 two that had been syringed the previous winter to kill brown-scale. We do 

 not approve of the cutting-back system in rearing Peach-trees. We have 

 la-'ge trees that were planted in 1878 now in full bearing, that under the 

 catting-back system would have taken double the time in attaining the same 

 dimensions. 



]\[n Greenfield. — Your double Cineraria is a marvel of its kind. The 

 colour violet purple, large truss, and each bloom about Ih inch in 

 diameter. 



A Eeader. — The excrescence in your Yine-leaves is caused by a too moist 

 atmosphere and insufficient ventilation, and those who tell you that it will not 

 do your Vines any harm are blind leaders of the blind. Keep your vinery less 

 damp and give more air, and, though it will not cure the foliage already affect- 

 ed, it will check the progress of the evil. 



S. Y. — The undergrowth plant on the stove-shelves is Fittonia argyoneura, 

 and the apron was of Panicum variegatum. There is no soil mixed with the 

 gravel, but a little weak guano-water is applied occasionally ; and both plants 

 are planted as cuttings, where they grow, every March.
