THE FLORIST AND POMOLOGIST. 
[January, 
and wlien they reacli this, they must from the concavity pass to the centre, where 
an outlet is provided in the leg at the base of the boiler, into which a pipe is 
inserted at A, with a tap attached, and communicating with a drain in the stoke¬ 
hole. Thus by simply turning the tap, the whole of the sediment can be cleared 
out, and the boiler left perfectly clean. The circulation's also well provided for 
—the flow, 0 c, being at the extreme top, and the water, after traversing the 
pipes, re-entering the leg at the back above the level of the sediment-pipe. 
This boiler can be fed either from the top or bottom, as may be preferred. The 
facility it affords for removing sediment, and the direct action of the flames upon 
the water-space, appear to be features specially deserving of commendation ; and 
there seems no reason to doubt that it will prove to be not only powerful, but 
also quick-heating and economical.—T. Moore. 
KOSE HEDGES. 
MONG the numerous improvements executed at Valentines by Mr. Earley, 
and one of the most valuable acquisitions to the grounds, is a Hedge of 
Eoses, not, however, after the form of that mentioned by Mr. Fleming. 
It is simply a ridge of wires bent neatly into form, and the Eoses trained 
from each side, forming a dense mass of flowering wood ; and the shoots have 
become so compact, that they show the Eoses in a mass and without shading. 
Many of the finest kinds, among which Marshal Niel was conspicuous, are planted 
and doing well. The free growth, though it is oompact, takes off all stiffness of 
form. —M. Temple. 
OFFSETS FKOM AUKICULAS. 
TFCE I penned some notes (1875, p. 165) respecting offsets from Auriculas, 
I have paid a visit to the Eev. F. D. Horner, at Kirkby Malzeard, Eipon, 
and what I saw there has led me to modify my opinion in one particular, 
namely, as to the necessity for offsets being rooted before they are sepa¬ 
rated from the plant. Mr. Horner is not a believer in this necessity, and his 
extensive practice with the Auricula lends the sanction of authority to what he 
says. 
Mr. Horner takes offsets from the plants at any time when they are moving, 
and he finds it convenient to remove them before they can throw out rootlets. 
So long as the offset has a heel, it will soon strike root. A statement has been 
put forth, with some pretence to authority, to the effect that offsets will not 
grow unless rooted previously to their removal from the plants, but Mr. Horner 
describes this as ‘‘perfect nonsense.” The late Mr. George Lightbody used to 
remark that offsets do best when placed round the sides of a pot, and Mr. 
Horner applies this principle, only he pricks his offsets round the sides in which 
the parent plant is growing, and many of his plants are fringed in this way at 
the present time. They soon make root, and are then potted off into small pots 
and placed in a cold frame. Any small off-sets have a small bell-glass placed
