tion often follows a great outrusli cf air by throwing the ventilators open 
widely after a house h.i3 been closed too long, and the air becomes too 
warm and moist, the transpiration or evaporation from the leaves beiu ' 
then too sudden and excessive. Admit air eirly by the top ventilators, in- 
asing it gradually as the heat of ths house increases, but never in such a 
volume at once as to cause a sudden fall in temperature. We are glad to 
hear our advice has resulted in the extirpatio a of mealybug from your 
vinery. 
Roots on Vine Rods (No Norte) —You neither send your name nor 
address ; and, as you may see from the notio above, matter intended for 
publication should be written on one eide of the paper only. Undoubtedly 
m low and very damp hou^e will influence the production of roots on the 
stems and Vine3. Free root action in a good border should be encouraged, 
and a buoyant atmosphere maintained in the vinery ; then the roots above 
ground may be exp cted to diminish without the Vines sustaining any 
check by their absen e. 
Mulching Roses—Tomatoo i (Kittie ).—If the soil is of a light nature 
and liable t > “ dry out ” in summer we should not fork in the long litter, 
jt3 it would make the ground still lighter, and the surface covering would 
be of service in preventing evaporat on; but if the ground is very heavy 
it would be improved by the manure being pointed in, provided the roots 
of the plants are not disturbed, and e-en then a covering of short manure 
spread on the soil on the approach of hot weather would do good; short 
manure would be better than long also for mul liing light soil. We bail a 
wall 10 feet high profitably covered with Tomatoes last year, the plants 
being 2 fe t apart, each confine! to on: stem, like a Vine, and the stems 
were covered with fruit; indeed, they contained noth ng but f u t and Urge 
leaves, all the axillary growths being rubbed out. When fruit does not 
set, however, from the main stem, axillary growths should be left and 
I upped close to each c uster of flowers as soon as formed. 
Pale Marechal Niel Roses ( J .).—It is the opinion of some growers that 
there are two forms of this Rose, and we have seen two plants in the same 
garden, one of which afforded rather small and pale, the other large and 
rich golden blooms; but do not for a moment suggest that yours is an 
inferior form. Mr. William Paul is too good a rosarian to be deceived, and 
the Marechal Niels exhibited by him are usually remarkable for their 
brilliancy. We suspect there is something wanting in the soil in your 
district that is necessary for imparting richness of colour to the blooms, 
and the example you cite of a plant budded from a Rose of deep colour 
producing pale blooms confirms that view, though the stock may have had 
some influence in the change. The liquid manure you have given, con¬ 
sisting largely of soot water, would have a tendency to deepen the colour 
i ather than the reverse. Some authorities are of opinion that at ace of 
iron in the soil intensifies the colour of flowers, hence iron filings have 
been employed for changing the colour of Hyd angeas. An experiment 
appears to be worth trying of sprinkling iron tilings on the soil over the 
roots of one of your plants, or giving water impregnated with iron. We 
hare no experience of any such trial, but know that Roses colour well in 
soil containing iron; whether the blooms wou’d be equally rich without it 
wc do not know. 
Forcing Pit ( Cambridge ).—We think your proposed arrangement will 
answer very well, the roof of course being made rigid without impeding 
the action of the ventilators. With those made to open to their full width 
or thereabouts side ventilation will seldom if ever be needed ; still we 
should have sliding shutters, or a 0-inch lid on hinges below the stage, to 
be used if required ; on the “ bed ” side we fail to see the necessity for 
ventilators, nor is glass by any means a necessity at the sides above either 
the bed or the stage. We should prefer the north end to be bricked up, if 
the wall were not objectionable as seen from the outside; inside it might 
lie covered and made attractive. The two 4-inch pipes enclosed in the 
chamber would be more than sufficient for affording bottom heat, and the 
one 3 inch round the house perhaps scarcely sufficient for top heat in 
severe weather, therefore we should have a lid or sliding door in the side 
of the chamber next the path, and should then expect sufficient heat both 
in the bed and the house. But it is not apparent how the top heat pipes 
can be taken all round ther house without crossing the path near the 
entrance at an inconvenient height above ground, though you can perhaps 
see your way to carry out that arrangement. We may say, however, it 
would not be wise to dip the flow down into the path and take it up on the 
opposite side. If the position of the existing boiler is such ns to permit 
the connection being made under the door, the flow pipe could be taken up 
one side, or cross the end of the bed or stage, and so conducted right 
round, returning down the other side to the boiler. With the piping 
properly arranged the boiler ought to heat both houses well. It maybe 
advisable to consider the possibility of wanting heat in the small stove 
when it is not required in the larger house, which is perhaps a conserva¬ 
tory, and make provision accordingly. The plunging bed should rest on 
slates; on the stage side corrugated zinc, surfaced with crushed shells or 
other suitable material, would be better than open latticework. 
Names of Fruits.—( W. P.).— Gloucestershire Costard. 
Names of Plants.—We oalv undertake to name species of plants, not 
varieties that have originated from seed and termed florists’ flowers. 
Flowering specimens are necessary of flow, ring plants, and Fern fronds 
should bear spores. Specimens should arrive in a fresh state in firm 
boxes. Slightly damp moss or soft green leaves form the beet packing, dry 
cotton wool the worst. Not more than six specimens can be named at once. 
(L. T.). —Owing to the flowers being packed in dry moss they were so mu h 
shrivelled as to be scarcely recognisable, but we should take it to bo Den- 
drabium thyrsiflorum ( n'. G. Tv.. Reading). —a. Resembles a small flowr r 
of Oncidium divaricatum; b. Miltonia cuneata. While the Ferns are 
small they will not injure the Orchids in the slightest, and you need not 
trouble to remove them until potting time. Many person* plant sma'l Ferns 
with th ir Orchids, especially such as Pleiones which flower without leaves. 
(G. tarrant ).—The plant is not an Orchis, but a member of the Broom- 
Rape family (OrobanchaceieJ and is known as Toothwort popularly, 
botanically as Lath rail squamaria. It is found generally in Europe and as 
far as the Himalayas. (E. B). —Thou .’h being grown under glass the spray 
does not represent the normal character of the p'aut, and we can only 
a ugge8t the possibility of its being Cryptomeria elegans nana.

PIGS. 
Since corn lias become so cheap in this country much 
more of it lias been used for pig-breeding by farmers, 
for the simple reason that pigs may still be bred, reared, 
and fattened profitably—so profitably, that within certain 
limits there is nothing which now answers better—few 
things so well among farm produce. Repeatedly has it 
been our experience that a demand upon open markets 
for any article that is tolerably easy of prodmtion usually 
gives rise to over-production, but this is hardly likely to 
prove the case with pork. The demand for it certainl) 
fluctuates somewhat, but it is unquestionably constant 
and steady.
