GLAZED PROMENADES AND GLASS WALLS. 
M MONG the wonders which the great 1851 has brought to light, glass walls for horticultural purposes 
A2\ are not the least remarkable for those interested in gardening pursuits. To Mr. Ewing, gardener 
to O. F. Meyrick, Esq., of Bodorgan, Anglesea, belongs the merit of directing attention to the subject 
at the present time, though a similar plan was proposed many years ago in the Gardeners' Magazine 
by Mr. Mallet, C. E. of Dublin. Cheap glass and the present building facilities, as exemplified in the 
erection of the Crystal Palace, enable us now to profit by the suggestion; though it is matter of doubt 
whether glazed promenades would not be very preferable to walls of glass. Walls, as proposed by Mr. 
Ewing, to make the best of them, being very narrow, will contain hut a small volume of air, and hence 
must he liable to sudden variations of temperature, being in a few minutes, when the sun strikes upon 
them, exceedingly hot, and on frosty nights correspondingly cold. For the growth of Peaches and 
other stone fruits during the time of setting and stoning, they will require the utmost watchfulness as 
to ventilation, and, indeed, being all glass, in gleamy weather in March and April, it is doubtful 
whether it will be possible to keep anything like an equable temperature; and every Peach forcer 
knows how difficult it is with the best 
management to set a regular crop of 
fruit. Apart, however, from their 
narrowness, and the small volume of 
air which they contain, we think with 
Mr. Rivers there is great waste of 
glass to no purpose, and that for the 
same, or a little more expense, narrow 
houses of great convenience might be 
constructed, which in addition to offer¬ 
ing shelter as promenades, will also 
produce double the quantity of fruit. 
The annexed engraving represents 
a house of this kind, in which either 
fruit trees or flowers may be planted, 
and the increase of glass for such a 
- structure is only as thirty to twenty- 
one, and the additional expense at the 
same ratio. A house of this kind, 
fifty feet long by twelve feet wide, using the best materials and performing the work in first-rate 
style, would not cost more than £100, and if ordinary materials were used it might be constructed 
for much less. But we believe in all horticultural erections cheapness and durability are not 
synonymous terms, and though a house may be erected for £50, perhaps one of the same size 
at £100 would twenty years hence be the most economical. Besides, as fruit-forcing may be 
considered one of the luxuries of life, we should like to see the trees growing in respectable 
habitations. Mr. Ewing’s glass walls, as shown by the drawings, would doubtless have a very 
elegant appearance; there is nothing make-shift about them, but they are worthy of a place in the 
best appointed gardens, being strong and substantial in every respect. In the house represented in 
the engraving, we suppose a neat iron or wood frame-work to be erected permanently, against which 
sashes (all made precisely the same size, viz., seven feet six inches long by three feet six inches wide) 
may be fixed by means of bolts and nuts, and the sashes to slide at the top in the usual fashion. If 
two houses of the same size were erected in the same garden, say one for fruit and the other for 
Perpetual Roses, one set of sashes would be sufficient, as the fruit would be ripe by the time the sashes 
were required for the Rose-house or winter promenade, and they might be removed from the Rose- 
house in time for the fruit in the spring. At the present time, the middle of January, we have buds
