SECTION IV. 



INTERIOR ARRANGEMENTS. 



1. Arrangements for the interior of forcing-houses, culinary- 

 houses, &c., are generally very much alike, consisting chiefly 

 of trellises of wood, or of wire, to w^hich the trees are trained. 

 The other portions of interior detail are common to horticultural 

 structures of every description, and will be subsequently de- 

 scribed in their respective places. 



"Half the advantages," says Loudon, (Ency. of Gard.,) "of 

 culture, in forcing-houses, would be lost without the use of trel- 

 lises. On these the branches are readily spread out to the sun, 

 of whose influence every branch, and every twig, and every leaf, 

 partake alike ; whereas, were they left to grow as standards, un- 

 less the house were glass on all sides, only the extremities of 

 the shoots w^ould enjoy sufficient light. The advantages, in 

 respect of air, water, pruning, and other parts of culture, are 

 equally in favor of trellises, independently, altogether, of the 

 influence which proper training has upon fruit-trees, as the vine, 

 the peach, apricot, &c., to produce fruitfulness." 



Notwithstanding the obvious utility of trellises in culinarj^ 

 houses, the use of them is frequently carried to a most unprofit- 

 able and injurious extent, when the whole interior of the house 

 is filled with foliage from the glass to the floor. Here, work is 

 entailed upon the gardener to no purpose ; and though good 

 crops may be borne on the trees that are trained upon the trel- 

 lises crossing the house, or on the back wall, the fruit is utterly 

 worthless. f 



The trellis, situated on the back wall, was formerly considered 

 the principal part of the house, for producing a crop ; but this 

 is only the case in small, narrow houses, and where no trees 

 are trained upon the rafters, or under the glass. Experience 

 has proved that, where the wl'.ole surface of the glass ' overed
