90 Broccoli from Slips. In a former part of the Auctarium we 
gave an account of the successful mode of propagating Cab- 
bages from Slips. Mr. Rutger, in the Gardener’s Magazine, 
has given an account of his success in propagating Broccoli by 
the same method. The heads having been cut off for use, in 
the spring, the stems were left to produce sprouts. In J une, the 
sprouts were slipped off, and after being exposed a day or two, 
in the sun, to cauterize the wound, they were planted in the usu- 
al manner. In two or three weeks they had taken root; and in 
the course of the autumn made fine stocky plants. l\Ir. Rut- 
ger says that he has seen many instances of Broccoli, thus grown, 
having heads three feet in circumference, and as close and com- 
pact as possible; butt his extraordinary luxuriance he attributes 
to the use of sea weed as manure. 
91 Ferns; Cultivation of. Ferns, from the variety and deli- 
cate forms of their fronds, are favourites with most cultivators of 
plants. The supposed difticuity of growing those species, re- 
quiring the protection of glass, caused their cultivation, for ma- 
ny years, to be limited to very few gardens. It is now rapidly 
extending, and with so much success, that in many places they 
are grown as readily as any of the [ihenogamous plants. The 
number of species, under cultivation in the various gardens 
throughout the country, is upwards of two hundred, and that 
number is still increasing by the importation ofliving plants, and 
from seeds taken out of herbariums. Twenty years ago there 
were not, perhaps, above thirty species to be found growing in 
the stoves and greenhouses of Great Britain. Attention to the 
following simple direction is all that is necessary to ensure suc- 
cess in their cultivation, under glass as well as out of doors. 
Those requiring the protection of the stove and greenhouse may 
all be grown successfully in the stove only; where they should 
be placed together for convenience of watering. It is immate- 
rial whether they be exposed to the sun, or kept in the shade, 
doing equally well in either situation. The most convenient 
place, however, is frequently the back of the house. Here they 
become an interesting decoration, under the shade of larger 
plants, where little else would succeed. The pots containing 
Ferns, must be kept rather moist at all times; and their fronds 
also require frequent waterings over head, with the syringe, or 
a w atering pot having a fine rose. This should be attended to
