THE FLORIST AND POMOLOGIST. 
[ June, 
saddle boilers, that bad been in use about eleven years, were taken out; 
one of these had given way and was worn out, while the other, though put 
down at the same time, proved to be in good condition. During the time I 
remained at Cobham, the tubular boilers acted very well, but consumed a 
great deal of fuel, and I much regretted the great waste of heat by the 
chimney. About four years ago I put down at this place one of Clarke’s 
water-jacket boilers, and although this worked very well, and several 
others put down in this neighbourhood at my recommendation are giving 
great satisfaction, I still considered the waste of heat escaping by the 
chimney as unsatisfactory. 
Having to replace an old boiler this winter, I determined to try whether 
the tubular boiler could not be made to work a flue inside the house, as well 
as pipes, by keeping the boiler well down. I put down last January one of 
Clarke’s water-jackets, and carried the smoke into the flue that the old open- 
topped boiler had worked, and the result is the most satisfactory of any¬ 
thing I have yet met with in the way of heating. I have cut off two other 
boilers, and attached two more houses to the new boiler, so that it is now 
heating three vineries, each about 60 feet long; and during the windy 
weather we have experienced, notwithstanding that they are old houses with 
open laps, there has not been the slightest difficulty in maintaining the 
required temperature. I do not say it would answer in all cases, but this 
answers remarkably well, heating the flue to a length of about 60 feet per¬ 
fectly ; and as nothing but coke is used for fuel, the flue is not likely to become 
choked with soot to impair its usefulness. There seems to be a liability in 
tubular boilers to give way, and I believe one of the boilers at Cobham Hall 
did so since I left there in 1861, but I think the proportion is not very large 
to the many that do stand well to their work. Without in the least wishing 
to depreciate the improved form of saddle or other boilers, I believe we 
have in Clarke’s water-jacket, when set in the way I have described, a most 
powerful and economical boiler.

BEDDING BOSES. 
v^UIJAB. PAUL’S observations (p. 74), on the bedding-out of Roses, will 
commend themselves to all true lovers of these beautiful flowers 
who have given the system a trial. It is gratifying to hear that 
the practice is on the increase, as it is a step in the right direction, 
and ought to be the rule rather than the exception. 
On this soil and with the system which I pursue, I find the vigorous 
and free-growing sorts to be the best adapted for beds. Mr. Paul has not 
included in his list one which we find to be peculiarly well adapted for 
bedding-out—viz., Souvenir de la Reine d’Angleterre, which is vigorous in
