heat ; if by fire, 72 or 75 degs., syringing and shutting 

 close up, early in the afternoon, allowing the tem- 

 perature in the night to fall back to 58 or 60 degs. 

 {Roberts s Cult, of the Vine, 22.) 



Mr. G. Fulton, gardener to Lord Northwick, also 

 concurs in the importance of a low night temperature, 

 though, like the late Mr. Knight, he finds that in 

 lighter days the vine will bear a very high tempera- 

 ture, occasionally, with advantage. 



He says, to have an attentive eye to the young 

 shoots at an early period of their growth is of great 

 importance; and, to procure round short-jointed wood, 

 his practice is to keep a low temperature in the night, 

 and a very high one in the day. Vines by such a 

 mode of treatment are not excited in an unnatural 

 degree, and nature is more imitated than exactly 

 followed, which may be said to be the main principle 

 in the art of forcing. He has frequently, in the spring 

 months, had the mercury in the thermometer stand at 

 110 degs. in a pinery early in a day, when, with 

 abundance of moisture, vines have grown very rapidly 

 with round short-jointed, instead of flat long-jointed 

 shoots, caused by an extreme of fire heat in the night. 

 The observations already made he wished to be un- 

 derstood as applicable to pines as well as vines, where 

 they are necessarily grown together. (Gard. Mag. 

 vi. 707.) 



Mr. Appleby agrees in the propriety of commenc-
