THE CULTURE OF ROSES UNDER GLASS. 
By Mr. Feank Cant, F.R.H.S. 
[Read June 11, 1895.] 
Vakious treatises have been published on the cultivation of 
Roses under glass, some of them emanating from very experi- 
enced Rose-growers, such as Mr. William Paul, Mr. Duncan 
Gilmour, and others, the latest being the chapter on the subject 
in the Rev. Foster Melliar's " Book of the Rose." I refrain 
from expatiating on this particular chapter. My reason for 
doing so will be understood from the reference to my name in 
the preface on page vi. in " The Book of the Rose." But in 
passing I must say, and I hope Mr. Foster Melliar will take it 
to imply no empty flattery, that " The Book of the Rose " is the 
most scientific, complete, and perfect ever published on that 
subject, and I strongly advise those who have not read it to lose 
no time in possessing a copy. Having said so much, it may be 
thought that a lecture on the subject in this hall is scarcely 
needed ; but amateurs complain that none of the existing 
treatises fully supply their needs, that rather too much knowledge 
on their part is taken for granted, and that more detailed infor- 
mation is needed on what may seem to be somewhat rudimentary 
points, such as the construction of a Rose-house and the 
different requirements of Roses grown in pots and of those 
planted in the ground. It must be remembered that the culture 
of Roses under glass is not at present very extensively carried on 
by amateurs, but is mainly confined to nurserymen, who, grow- 
ing their Roses for sale or exhibition, necessarily cultivate them 
for the most part in pots, which, as they can be transferred into 
the open air after blooming, and remain there during the 
summer months, do not require quite the same construction of 
house as is needed for Roses planted in the ground. The first 
point, therefore, to which I wish to draw attention is the structure 
of the house, which should be equally suitable for growing Roses 
permanently planted in the ground and for those in pots. There 
may doubtless be varieties of makeshifts, such as a lean-to, which 
should face east or west, due south being the least desirable, or a 
pit roofed over, and good Roses may be grown in either of such
