successful. For covering walls CotoDeaster microphylla and 

 Simmon sii maybe nsed, and in many instances Ceanothns 

 azureus and Yeitehii do very well. 'Worth noticing also is the 

 success of the Elder as a screen in kitchen gardens, fruit 

 quarters, &c. Around the Mount's Bay in particular, the seat 

 of the earliest vegetable and fruit produce of the country, these 

 may be seen more frequently than elsewhere. The cuttings 

 strike easily, and planted in single rows in a few years run up, 

 and when kept close-cut the little ground they occupy, the 

 rapidity and close inwoven-form of growth, would make this 



screen, but for its drawback of being deciduous, and, I suppose 

 I must add, want of beauty, the consummation of shelter. 

 Privet, Hornbeam, Thorn, and other fencings are tried fre- 

 quently, but never with the success of an Elder hedge. In 

 ground, however, where appearance is more important, the 

 Escallonia makes the best evergreen hedge ; in Scilly it is the 

 favourite, and does most of the hard work there. In fact, this 

 is among shrubs what the Poplar is amongst trees, indispen- 

 sable to success in seaside planting. — Cobsubia. 



GLASS 

 The accompanying engraving is a representation of a struc- 

 ture I have recently erected. It differs somewhat from those 

 I have called double walls of glass ; it being the intention to 

 force th6 fruit in this structure, it was necessary to add a roof, 

 in all other respects, with this exception of its being wider at 

 the top, it is similar to the glass walls which I first introduced. 



In this struc- 

 ture the venti- 

 lation is not 

 only in the roof, 

 but on each side 

 under the gut- 

 ter which car- 

 ries off the 

 water from the 

 glass, the earth 

 being removed 

 to the depth of 

 4 or 5 inches, 

 thus enabling 

 the air to pass 

 up between the 

 trellis and the 

 glass, birds be- 

 ing excluded by 

 galvanised wire 

 netting. 



In a former 

 article I have 

 described the 

 mode in which 

 the glass is fixed 

 in grooves, in 

 which are in- 

 serted triangu- 

 lar pieces of 

 copper to clasp 

 the glass, keep 

 it tight in the 

 grooves, and 

 prevent one 

 .sheet of glass 

 slipping down 

 over the other. 

 I have also 

 described the 

 mode of prepar- 

 ing the timber, 

 so as to render 

 unnecessary any 

 painting after-

hope that insects will not harbour in timber that 



boiled in creosote. Some persons object to the colour of the 



wood thus prepared' which in the course of a few months 



becomes of a rich brown ; if thought proper the fronts of the

rafters might be painted stone colour in the course of a year, 

 which would give the whole a lighter appearance. 



As I have before alluded to the advantages to be derived by 

 this mode of growing fruit, I will merely mention a few of its 

 most important features — viz., thorough control over autumnal 

 rains ; perfect ventilation by the passage of the air between 



the trellis and 

 the glass, both 

 surfaces of the 

 leaf being thus 

 exposed tolight, 

 for without 

 quality in foli- 

 age we must not 

 expect quality 

 in fruit ; tho- 

 rough ripening 

 of the wood ; 

 command over 

 the red spider j 

 and, to crown 

 all, we have 

 every part of 

 the "fruit tho- 

 roughly ripen- 

 ed. I may also 

 add that early 

 fruit is ripened 

 a fortnight ear- 

 lier, and that 

 late fruit be- 

 comes tho- 

 roughly ripe. 



The fruit trees 

 in the structure 

 here engraved 

 consist of vari- 

 ous kinds of 

 Peaches, Necta- 

 rines, Apricots, 

 Plums, Cher- 

 ries, Figs, 

 Strawberries in 

 the border, and 

 Grapes, the last 

 being trained 

 along a wire 

 under the ven- 

 tilator, which 

 ventilator is 

 opened or shut 

 simultaneously throughout the whole length of the structure by 

 the usual mode of a winch. I was induced to try various experi- 

 ments to insure a crop of fruit independent of the weather, a 

 very large supply being here required for consumption. I have 

 now had sufficient time to test this last experiment, aDd I can re- 

 commend its adoption with the greatest confidence.— Obsebveb.

and the latter rain." It works to send the rills and streams, 

 like lineB of silver, adown the mountain and across the plain. 

 It works to pour down the larger brooks which turn the wheel 

 that energises machinery, which gives employment to millions. 

 And thus a thousand wants are supplied, commerce stimulated, 

 wealth accumulated, and intelligence disseminated through the 

 agency of this wealth. The leaf does it all.
