246 THE PEACH AND NECTABINE. 



The curvilinear peach house is an excellent form for early peach houses, 

 or in nnfayonrahle climates or localities. It admits more and clearer 

 light than almost any other. The trees may be trained according to the 

 curve of the roof, or, rather, increasing the distance from the roof as it 

 ascends, as shown in (a. Fig. 55), or the trees may be planted on the back 

 wall, and also trained over a curved trellis, as shown, extending from 

 the front of the house to the path at back (b, Fig. 55). The Ught is so 

 Intense in these houses that the trees do well on the low trellis, which 

 leaves almost the whole of the back waUs available for another set of 

 "trees. Of course, where the roof trellis is used, as shown by the dotted 

 line under the roof of Fig. 56, no trees are planted on the back wall, for 

 the whole area of the glass is already occupied. 



IV.— Trellises. 



Ths general cultivation of the peach under glass differs but little 

 from that in the open air. The subject, however, naturally divides 

 itself into two parts, that may be designated the permanent and 

 the portable, that is, the trees may be either planted out or grown 

 in pots or tubs. The more common method is to plant out the 

 trees near the front of the house, and train them upon a roof trellis, 

 about 18in. or 2ft. from the glass. This trellis is often carried up the 

 whole length of the roof. (See Fig. 56.) At other times it is carried up 

 about two-thirds of the length of rafters. This mode of cutting off the 

 roof trellis is considered the most provident of space. Assuredly it 

 improves the appearance of the houses. A roof trellis stretching from 

 base to summit of a wide peach house is a noble sight, and peaches 

 colour and flavour to more perfection on such trellises than grown in any 

 other way. But the bare back walls have a, bald and barren look. By 

 cutting off part of the roof trellis the back wall may also be clothed with 

 trees. Biders, with clear stems of 3ft. to 6ft. high, according to the 

 .height of the wall and the length of the roof trellis, may be used for 

 this purpose. Such trees often do exceedingly well, as they have the 

 free run of the borders lying all in front of their roots. 



The trees on the trellis, unless allowed to run outside, which is often 

 done by building the peach house on arches, are rather placed at a 

 disadvantage in this matter, for it is found that roots do not travel so 

 freely to the north as to the south. The sun seems to draw the roots as 

 much or more as the tops of plants. To meet this objection in early 

 peach houses, in which the roots are generally confined to the inside, half 

 standards are frequently employed. These are planted about the centre 

 of the border and trellis, and spread over the latter in all directions as
