mid atmosphere produced by watering or syringing, and spe- 

 cial care be taken that after such an accession of heat the re- 

 cession be not sudden. The night temperature may range 

 uniformly about ten degrees below that of the day, the state 

 of the house being sedulously watched, its slightest variations 

 being indicated by a double registering thermometer. 



Besides a very severe system of summer pruning, almost 

 entirely suppressing growth, there are in fruit forcing various 

 other nice points to be attended to, the detailed minutiae of 

 which will be found in works specially devoted to this depart- 

 ment of fancy culture, and these scanty general indications are 

 all that can be given here. 



The ripening of the larger fruits will generally be effected in 

 about five months from the first application of heat. 



TRAINING. 



"TRAINING" is any process by which the young growth of 

 trees or shrubs is diverted from its natural eourse, and made 

 to take such directions or assume such forms as the fancy 

 of the cultivator may prescribe. Hence the various kinds of 

 training are designated as "upright," "horizontal," "'fan- 

 shaped," " weeping," " coiled," or " winding," etc. For illus- 

 trations of the two former see Arbor and Trellis Culture of the 

 Grape, p. 349-50. 



Training the larger fruit-trees upon trellises is, in general, 

 merely a fancy mode of treating dwarf trees like the weeping 

 cone and other peculiar forms, or it is practiced in preparing 

 such trees for the ornamentation of path sides, etc. ; but train- 

 ing such fruits against walls or other shelters is adopted with 

 a view of producing in ungenial climates fruits not otherwise 

 producible in them, or to obtain in perfection in unfavorable 

 localities or soils certain fine varieties of fruits, which even 

 the processes of dwarfing and summer pruning do not enable 

 us, under the circumstances, to ripen satisfactorily. It may 

 be practiced in either or all its forms so far as time, means, 

 and taste permit or prompt. 



Where it is proposed to cultivate " wall fruit," as the prod- 

 uct of trees so trained is termed, the borders or holes for the
