It is, in fact, highly problematicalwhether the extra liabUity to injury induced by day forcing is baJanoedby the extra protection afforded by a mere glass screen at night. II.—Orchard Houses. The majority of these are span-roofed (Fig. hi) ; bnt lean-to orchardhouses also abound. It is obvious that the term is applied rather to formof trees and style of culture than to any special variety of glass Fia. 51. The term is also used by many cultivators to designate houses that areeither unheated, or to a less extent than peach houses. Most of thesedistinctions are^ however, arbitrary, and as orchard houses increase andmultiply, they will probably lose their present significance, for thereseems no good reason why a peach orchard under glass—:that is, an orchardhouse—should not be forced or treated exactly like other peach houses also differ broadly from glass oases, inasmuch as theyare seldom erected against walls already furnished with peach trees, butrather filled with trees of a more free style of growth. However, thereare also orchard liouses filled with cordons and trees trained on trellises. CULTURE UNDEB.
