but surely when a, very low temperature isexperienced, common tanned 
netting, or tiffany, thrown over the surface of the glass would prevent 
any mischief from taking place. And the occasions when such would 
be required are so few as to require no further comment. ae 
We should not remove the covering in winter ; there 1s no cccasion 
for it, however well ripened the wood may be. Let'the bottom and top 
ventilators, however, be removed or fully opened, that the air may play 
freely over the trees, but exclude wet, which not unfrequently induces 
gum, particularly in luxuriant trees. | The glass, too, will afford a slight 
protection to a number of things which the gardener Has always oecasion 
to preserve. The wall should be trellised ; it will bea small expense 
at first, but this will be repaid by the facilities afforded for training in 
comparison with nailing, and by the fruit not’ getting injured by nails, 
and the ease with which insects can be kept-down, when the shoots are 
trained to a trellis, which need, however, not be more than afew mehes 
from the wall. 
The worst enemies to the Peach, in the shape of insects, are the Wiadk 
and green flies. Their destruction on walls can only be effected’ by 
washing with the engine or syringing with tobacco-water. During such 
cold seasons as the last, the remedy of washing was almost as fatal as 
the effects of the insects we wished to keep down; and to be continually 
using tobacco-water is expensive and troublesome; under glass, the 
complete extirpation of the aphides is readily effected by fumigation, 
without injury to anything; and if taken in time, one or at least two 
good fumigations will answer for a season. We have grown Peaches m 
houses frequently without requiring fumigation at ali; the great ‘point 
is, not to let aphides become established, but to attack ‘them the instant 
they are seen. 
We shall say nothing about forwarding the ripening of the fei 
this is not our object, though of course it may be done at pleasure ; but 
at present we have only to compete with wall Peaches, keeping them, 
however, as late as they will ripen freely, to be worth eating. It is'a 
mistaken notion to suppose that under glass the fruit would ripen much 
earlier than on open walls, and would not keep. The fact, as proved by 
orchard houses, is that, with full ventilation, the Peach does not ripen 
so early as on the open wall; with glass, therefore, you have the option 
of being either forwarder or later than with walls only ; ; with theadvan- 
tage of ripening such late French Peaches, as the Salway, Desse, Favie 
de Pompone, &c., to perfection should'a bad season occur.) ” 
We have no room to enter upon the question’ of the ° origin’ of the 
disease, which is mainly owing to the low temperature of ‘the present 
spring followmg the severe frosts of last October; but there is one 
peculiarity about the dying Peach trees, which appears to have escapéd 
notice, and which does not admit of ‘so easy an explanation, and which 
Is, that trees on east and weet walls Have not suffered he arly so much 
as those on south walls have done. We may probably notice this: faet
