MEMORANDA ON THE CAMBRIDGE GARDEN.

carnations, or other flowers liable to be preyed on by these in¬ 
sects, a hand-glass set over them, and the smoke puffed in below, 
will free the plants effectually. 
In a farmer’s garden at Ditton, near Cambridge, I noticed a 
remarkable variety of the rose, of so brilliant a scarlet that, at the 
distance of a hundred yards, the bush appears to be decked with 
field poppies. On making inquiry about it, I found it was an old 
family favourite, and was called the Austrian rose. The flower 
is single ; and from its habit it appears to be only a variety of the 
common dog-rose : but in looking into Loudon’s list, I find the 
Austrian to be a variety of the Rosa Gallica lutea, with yellow- 
orange flowers, introduced into this country from Germany in 
1506. Be the name what it may, its colour is more intensely 
scarlet than that of any other of our common species or varieties. 
The aphides which encumber the shoots, and the tortrici that 
roll themselves in the leaves of rose-trees, have been alluded to ; 
but the “worm in the bud,” which destroys so many of the first 
flowers, is an insect called by entomologists the Lozotcenia ro- 
saria, and if any means could be devised to offend or drive 
away the mother insect from laying her eggs on or in the buds 
in autumn, our rosariums would be much more attractive than 
they usually are, in consequence of the depredations of these 
pests. The double yellow rose, or briar, one of the most valued 
of the tribe, is seldom seen in perfection, owing entirely to the 
attack of the lozotaenia, which almost always eats away one side 
of the bud. Hence it is obvious that there is as much care and 
skill required in preserving our finest roses, as in propagating and 
growing them; and, surely, the obtaining of roses in the greatest 
perfection, is well worth the extra labour of bestowing fumigations 
on the trees, early enough in the season, so that the scent may 
not be vitiated by the tobacco smoke. 
To the foregoing remarks on the rose I may add, that the 
petals of R. Gallica and R. Damascena are collected for the 
purpose of making infusions and a confection, both much used in 
medicine. Rose-water and the attar of roses are both procured, 
says Burnet, from R. centifolia. About six pounds of rose leaves 
will make a gallon of good rose-water ; but from two hundred to 
two hundred and fifty pounds weight are required to yield one 
ounce of the attar !—hence its high price. M.
