III.-SOCIETIES, 
CONNECTED WITH HORTICULTURE AND NATURAL HISTORY. 
LONDON HORTICULTURAL SOCIETY. 
The principal articles which have appeared at the Meetings have been Dendrobium specio- 
sum, Acacia dealbata in great perfection from the open air, Azalea indica phoenicea, Cyrto- 
podium Andersonii, five feet in height, a fine plant ofPhaius Tankervillise, Berberis glmnacea, 
B. fascicularis, B. aquifolium, and B. heterophylla, Seedling Rhododendrons, and collections 
of Camellias, Epacris, and Narcissus. Very good specimens of Cucumbers, Lemons, and 
Oldaker’s Seedling Pine Apple have also been exhibited, together with an improved garden 
engine and hoes of a peculiar construction from Col. Le Conteur, of Jersey and Lord Vernon. 
Col. L’s is more especially adapted for working between drills, that of Loi'd V. has been no¬ 
ticed by us before, and is a very efficient instrument. Papers have been read on the culture 
of the potatoe, on the preservation of green peas for winter use, and an Abstract of the Meteo¬ 
rological Journal for 1832, kept at the garden of the Society. The experiments instituted by 
Mr. Knight with the potatoe plant are still going on, and with every chance of a result most 
beneficial to the interests of the cultivator. The first of the proposed exhibitions at the gar¬ 
den, is fixed to take place on the 25th of May, and promises to be very attractive, if the season 
should be sufficiently advanced ; the exhibition of articles is open to all who may desire to 
contribute. 
Dr. Lindley commenced his course of Lectures, on the 24th of April; the subject of it was 
Mildew. 
IV.—MONTHLY HORTICULTURAL CALENDAR. 
FOR MAY. 
April has been remarkable for the quantity of wet weather, which has deterred operators 
from getting in the crops till late. Wall-trees will still require protection. Sowing and plant¬ 
ing for snccessional crops are necessary to a considerable extent. Insects must be narrowly 
looked after and destroyed. Grapes in the stoves, or vineries, will want thinning out, and the 
young wood of the Vines tying in, and stopping. Ridges for Cucumbers should be made. 
Annuals of several sorts should be transplanted; and cuttings of many green-house plants put 
in. Look well to the Cucumber and Melon frames; and give green-house plants air, night and 
day w'hen the weather is tine, which will much prolong the flowering season. 
FRUIT DEPARTMENT. 
Apricot Trees will now require examining, and the Caterpillars secreted in the buds, des¬ 
troying. See Calendar for April. 
Peach Trees in houses, started in December, will now be swelling up. Keep the heat from 
70 to 75 by day, and 65 to 70 by night. 
Cherry Houses .—The fruit on those started in January, will now be stoning. Be very care¬ 
ful, that the thermometer range no higher than 60 deg. by day, and 55 by night, until this criti¬ 
cal period is over, when the heat may be raised to 70 by day, and 65 by night. Give abun¬ 
dance of air, and syringe the trees until the fruit begins to ripen, when it must be discontinued. 
Vines in pots, now- brought into the vineries, will ripen their fruit the end of July; aud those 
introduced up the rafters, will ripen their fruit in October. 
FLOWER DEPARTMENT. 
Dahlia Seed should now be sown on a slight hot-bed, or in a warm situation. 
Auriculas towards the end of the month, will require potting.—See Vol. 1, page 56. 
Polyanthuses will now require potting, &c. See Vol. 1, page 448. 
Ranunculus beds will now require a liitle shading, to prevent the leaves turning yellow. 
Ticfridia pavonia .—Seed sown the end of March, or beginning of April, will now have pro¬ 
duced plants large enough for transplanting. Plant them out on a slight hot-bed in rows four 
inches apart, and two inches in the rows. 
Hardy Annuals may still be sown, either when the seed sown before has failed, or when it 
has been altogether omitted. Page 110.
