methods Mr. Aeon considers objectionable : the first, because 

 the house is rendered too dark, and the fruit liable to be in- 

 jured by cold air blowing through the interstices of the glass 

 in stormy weather ; and the second, because the plants are 

 frequently scorched by the heat of the flues. Mr. Aeon adopts 

 a wide flat-roofed house {Jig. 19.), plants the vines within the 



house at the back and front [a d), trains them on an arched 

 trellis, with horizontal wires one foot apart (Z>), and on the 

 back wall (c). He commences forcing on the 1st of Sep- 

 tember, and the fruit begins to be ripened about the first 

 week in March, and continues to be gathered till the middle 

 of May. About six weeks after the forcing has commenced, 

 vines are introduced from the front, and trained under the 

 rafters, which yield a succession crop, from the early part of 

 May till late in June, when the vines in the pine-stoves pro- 

 duce their crops. By the form of the trellis, which admits of 

 the use of the whole of the back wall, and of at least one shoot 

 on each rafter, this house presents the greatest possible surface 

 for the growth of the vines, consistent with sufficient light. 

 Mr. Aeon has proved by experiment that vines will ripen their 

 fruit a fortnight sooner on the trellis, than on the rafters. 

 Though of the utmost importance to have the roots of the 

 vines planted within the house, and secure from external ex- 

 posure, Mr. Aeon does not by any means desire to have the 

 mould in which they grow heated by the fire. " Few plants," 

 he states, " will thrive well, if the earth in which their roots 

 are placed is warmed by any other means than that of the
