and has it had any share in producing those yellow roses which are this 
year, so common, twos and threes in every nosegay of roses bought at 
Covent Garden ? and also can you inform me the name of the French 
rose I have mentioned ? 
London, June 7tli , 1841. 
The Austrian Briar ( Rosa bicolor) has received that name because it 
was first sent to this country from Austria; but it is a native of the north 
of Italy, Piedmont, and the banks of the Phone in France, growing 
abundantly on the hills near Lyons. Its petals are of an orange red, or 
copper colour, on one side, and yellow on the other; and it is said to be a 
variety of the yellow Austrian rose, Rosa lutea. The Austrian briar has 
never been known to produce seed in England, or to have double flowers. 
The yellow Scotch rose is a hybrid, between Rosa spinosissima and 
R. lutea. Its flowers are semi-double, and they are not only produced in 
great abundance, but open freely, with very little care, in almost any 
soil and situation. Williams’ double yellow Sweet-briar is a hybrid 
between Rosa lutea and R. rubiginosa , the common Sweet-briar; and 
Rosa Harrisonii , the best and by far the handsomest of all the new double 
yellow roses, was raised in America from seed of Rosa lutea , which 
produces seed freely in that country, though it very rarely does so 
in England. I suppose the French rose alluded to must be the Jaune 
Desprez, as that is of a pale yellow, or buff, and pink in the centre. The 
new, very large rose, Rosa devoniensis , is yellow in the centre. 
All these roses, except the last (which is only in the Exeter Nursery, 
are in the Horticultural Society’s Garden ; and I suppose the success that 
has attended hybridising with Rosa lutea (which never used to produce 
seed in England) has occasioned so many more yellow roses to be grown 
now than formerly. The old double yellow ( Rosa sulphurea) seldom 
produces perfect flowers; and for this reason, notwithstanding its beauty, 
it is seldom cultivated.

The Italian mode of cultivation is as follows :—First, there are growers 
of mulberry-trees, who, when these have arrived at sufficient size to allow 
of the leaves being plucked without injury to them, pluck and sell them by 
weight to the breeders of the worms. Of the worm-breeders there are
