QUERIES AND ANSWERS. 
Seeds. —It has been remarked, that seeds occasionally vegetate in one half 
the time they usually require. Is this from accidental circumstances, or may we 
assume that one particular period of the year is better suited than another for 
each sort of seed ? 
China Roses. — At what time of the year will the different kinds of China 
Roses best strike in a green house, without using bell glasses ? C. C. C. C. 
CEnotiiera Grandiflora. —Can any one of your really practicaal readers 
—one who is taught by experience—furnish the readers of the Register with di¬ 
rections for bringing the seedvessel of the Oenothera Grandiflora to maturity, so 
as to produce seeds, whereby to propagate that beautiful species? Electrjcus. 
Roses. —Where, in London, may the best selection of roses be purchased, and 
what is the distance from each other they should be planted ? II. H. 
On the New Way of Growing Early Potatoes. —I have read with some 
interest the communication of Mancuniencis, page 338, of your last number, on 
“ A New Way to Grow Early Potatoes,” but I feel at a loss to know how the 
ground was formed, and how the potatoes were planted,—whether on the ridges 
or in the trenches, or by the side of the trenches. If the mode be so easy, cheap, 
and certain, as there stated, I am sure Mancuuienies, yourself, or any other per¬ 
son, by giving in your next number, full practical directions for preparing the 
ground, stating the manner and time of planting, and what should be the subse¬ 
quent culture, as welljwith respect to those planted in the open ground, or in, or 
against, an hot-bed, as there recommended, will be conferring a great favour on 
the public. 
On the Turnip Fly. —How is the brine prepared, and of what strength, 
for steeping the turnip seed, previous to sowing, and what is the time it should 
remain in steep, in order to protect it from the attack of the fly when it comes 
up, as recommended in page 375 of the same number? 
On Slugs. —My garden is much infested with Grubs and Slugs, which of 
course are very destructive. Is there any better remedy than liming the. land ? 
If not, when, and in what quantities, should it be laid on, and should it be suf¬ 
fered to remain a short time on the surface, or be dug in immediately ? Amicus. 
Formation of Hot-beds.—I should be obliged by receiving any instruction, 
through your Register , from you or any of your correspondents, respecting the 
formation of hot-beds, for forcing small fruits, striking cuttings, &c. See.

Witty’s Patent Gas Furnace.—I beg to offer a few remarks on the advan¬ 
tages said to be derived from the use of Witty’s Patent Gas Furnace, as applied 
to horticultural purposes, having read Mr. Chanter’s statement in the last num¬ 
ber of the Horticultural Register, and the reports therein contained, said to be 
the testimonials of practical and celebrated Horticulturalists, of its general util¬ 
ity. However practical and celebrated they may be in horticulture, they seem to 
have had a small share of practical knowledge of the real use of the Gas Fur¬ 
nace. During the two years’ experience which I have had in its application, I 
have found it to be of no use whatever, when applied to steam boilers; and I am 
borne out in this opinion by persons who have tried it. The great advantages 
which it is said to possess over the common furnace, are these; namely, a great 
saving of fuel, a better retainer of heat, requiring less labour, and entirely con¬ 
suming the smoke. These, no doubt, are objects of great importance, and much 
to be desired, but had l found it to have possessed any of these advantages, 1
