Portable glazed Structures, 



establishment, they ought to 



be in every respect alike, so 



that the rafter, sash, or house, 



that fitted one place, might 



fit all. The reason for this is 



obvious, when we consider 



that the fruit, in many cases, 



requires protection, long after 



fire heat is unnecessary. In such cases, the pipes might be 



moved to the late division, and a house probably spared from 



another part of the wall. Such 15 



houses would, also, require to be 



formed of the best materials, the 



best workmanship, and made to 



fit accurately: this would render 



their removal safe and easy. 



Were a number of such houses 

 in a garden, they could not, in the first part of the season, 

 be all employed in forcing grapes and peaches : but they need 

 not be a moment idle ; they may be employed in forwarding 

 and protecting in many ways. Fig. 15. shows a compartment 

 in the kitchen-garden, fiO ft. by 30 ft., planted with asparagus 

 (a), rhubarb (i), sea-kale (c), truffles {d)^ and with boxes of po- 

 tatoes (as shown in the section, ^y%. 17. e)^ and mushrooms (_/). 

 The side {a) next to the wall must be covered with the glazed 

 sashes from a division of the wall ; the other side [b c d), with 

 wooden shutters, painted black, and working in rafters, the same 

 as the sashes. The whole may be heated by pipes up the centre 

 [g). When it is considered that all these vegetables are enjoying 

 their natural position in the soil, their roots unscorched by flues, 

 I venture to say that no structure of the present day, heated by 

 one fire, could equal it. When the vegetables are all gathered, 

 the pipes and glass part of this structure may be moved to the 

 next division of the wall, and the forcing recommenced as the fruit 

 may be wanted in succession. We have now the boarded part 

 of this structure to deal with ; and I would not allow even this 

 to remain idle. If a row of cleft posts were placed between a 

 double row of espalier cherries, the shutters laid lengthwise 

 upon single brickwork, raised 18 in. above the surface, it 

 would form upwards of 200 ft. of wall 6 ft. high. The north 

 and south borders of this wall planted with strawberries, and the 

 whole covered with a net {Jig. 16.), would form no contemptible 

 supply of superior fruit. There is, in fact, no end to the pur- 

 poses to which such things might be applied; and an astonishing 

 produce might be reaped from a very small garden, with plenty 

 of such means. 



To show with what facility such structures may be adapted
