HORTICULTURAL NOTES.

until the stem of the tree is of the required 
height. He considers Avinter pruning the 
best. 
Potter's Guano. — Mr. M'Millan, in apply- 
ing this substance to potted plants, met with 
the following results: — Leschenaultias bene- 
fited, the plants dressed with it did not damp 
off so much as others. Camellias and Oranges, 
much improved. Azalea indica, Zichyas, and 
Hardenbergias, injured. Boronia serrulata, 
Phoenocoma, and Elichrysums, grow most lux- 
uriantly. Ericas seem all fond of it, and 
grow very vigorously. Verbenas, Heliotropes, 
Geraniums, and Fuchsias grow out of charac- 
ter. Roses are improved. A very small 
quantity killed Salvia patens. Achimenes and 
Gesneras were benefited by a weak solution, 
but when used stronger they died. Except 
in the last case, it was used by sprinkling a 
little of the guano on the surface of the soil, 
and stirring it in. 
Woop Ashes.— Ground infested with mag- 
got, and on which carrots could not in con- 
sequence be grown, was cleared, and a fine crop 
of carrots obtained, by using a dressing of wood 
ashes. A portion of the same ground to which 
guano was applied, when the carrots were a 
little advanced, and infested with the maggot, 
failed to produce any benefit : this was at Bal- 
carres Garden. 
Akaucaria imbricata. — The plant of this 
noble tree at Dropmore, has the branches per- 
fect to the ground. Since 1837, it has grown 
fifteen feet in height, thus giving an average 
of more than two feet in a season, a progress 
worthy of note, when it is recollected that this 
tree has the character, of a slow grower. 
Hand-glasses. — Almost all these articles 
are inconvenient and fragile at the best. The 
frames, except cast-iron ones, wring so much, 
that the glass is seldom long in repair, and if 
they are of cast-iron they are heavy and in- 
convenient. There is every chance of the 
best being in a great measure superseded by 
the old-fashioned bell-glass, or something of 
the same manufacture of a better form. It is, 
in the first place, to be recommended as a mat- 
ter of economy, and next as a subject every 
way superior for use, nor will it be so liable to 
constant accident. Those who possess, and 
many do, some of the old bell-glasses, and have 
been used to them for years, will testify their 
superiority; and they were only superseded 
by the leaden zinc, and ultimately copper and 
east-iron framed hand-glasses, when the in- 
creased duty increased their price. The 
slighter and smaller bell-glass used for* cut- 
tings, and almost indispensable in propagation, 
are superior to every manufactured contri- 
vance with frames. The superiority of one over 
the other demonstrates the effects on a larger 
scale, and we may expect to see once more 
blown glasses in use instead of those made of 
small pieces in metal frames wherever large 
glasses are required. 
Reduction on Glass. — Amisapprehension 
has been caused by some of the public journals 
having given out that the trade refuses to let 
the public have the benefit of the reduction in 
the duty on window-glass. A sort of tirade 
has been run out against the companies, which 
may apply to some, but not to all. There is 
no manner of doubt that glass of a particular 
kind adapted for greenhouses, conservatories, 
and other horticultural buildings, ought to be 
reduced quite the full amount of the duty 
taken off; but it should be recollected also, 
that glass above a certain size was entitled to 
the drawback for exportation, and that squares 
under a certain measurement were not entitled. 
The consequence of this was, that all the waste, 
as it was called, which meant pieces under a 
certain size, were never exported, but had to 
be used up in this country; for squares en- 
titled to the drawback could be supplied actu- 
ally cheaper than the smaller; therefore squares 
under the size never bore a real proportion of 
price to those above it, and therefore we must 
not calculate upon the small glass yielding the 
public what the larger glass does; and besides 
this, there is a treble demand for glass, which 
cannot but advance the price of the article, the 
demand for labour, and the difficulty of pro- 
curing it. There is, however, plenty of glass 
to be had at a third of the pi'ice it bore pre- 
vious to the reduction of duty. Glass for 
horticultural purposes will ultimately be had 
at three-pence, and perhaps two-pence half- 
penny, per pound, and a pound to the foot will 
be ample strength. 
New Bizard Tulips. — Mr. Wilmer has 
exhibited a Bizard Tulip which has every ap- 
pearance of a cross between Polyphemus and 
Austria. The outside was a little coarse, 
but the inside was as fine as need be. It is a 
better yellow than Polyphemus, and the tex- 
ture appears good. It was awarded the Bizard 
prize at the Hampton Tulip Show, and was 
named Cardinal Wolsey. Mr. West of Shil- 
lingford showed another, which was a good 
colour and pretty inside, but it was almost egg 
shaped, and appeared difficult to open. Mr. 
Lawrence showed a most beautiful specimen 
of a Bizard newly broke, after the style of a 
fine Donzelli, but so superior, as to be gene- 
rally admired, 
Wireworms. — There is no plague in a 
garden more destructive than this little indus- 
trious, though slothful-looking, insect. Where 
they abound, whole crops are destroyed in a 
few hours ; and if a solitary specimen gets 
into a pot of carnations, it will not only de- 
stroy those which it finds there, but, if undis- 
covered, will go all through the pots on the
