III.—SOCIETIES, 
CONNECTED WITH HORTICULTURE AND NATURAL HISTORY. 
LONDON HORTICULTURAL SOCIETY. 
The month of May was distinguished for the excellence of the articles contributed both at the 
Meetings which usually take place in Regent-Street and, in numerous instances, at the first 
grand exhibition held at the garden. The sudden change which had taken place in the tem¬ 
perature of the season, was, however, found to favour the articles exhibited at the one as 
much as its effects were hurtful to the productions displayed at the other. The principal arti¬ 
cles received in Regent-Street during May were very fine specimens of Magnolia gracilis, M. 
Soulangeana, M. obovata, Enville Pine Apples, Sweeney Nonpareils, Gladiolus blandus, Ra- 
mondia Pyreriaica, Schizanthus retusus, a seedling Pasony from P. papaveracea, Oncidium 
papilio, 110 heads of Asparagus weighing 31J lbs., Hybrid calceolarias, some splendid Cactu¬ 
ses including the varieties Speciosus, Speciosissimus, Jenkinsoni, flagelliformis, and Specio- 
sus grafted on Opuntia. The three first named, possessed from one to two hundred blossoms 
on each plant, and presented a most imposing appearance. On the 25tli, about 2000 visitors 
attended the first of the three Meetings at the Society’s garden, where a very fine show of 
flowers took place, notwithstanding the extreme heat and dryness of the weather w r hich, opera¬ 
ted materially against it. The exhibition was arranged under an elegant tent of very large 
dimensions, and the scene was enlivened by the presence of the Tyrolese Minstrels and the 
band of the Grenadier Guards. The following award of Medals was made by the Judges.— 
The large Medal to Mr. Snow, gardener to J. H. Palmer, Esq. for the superiority of his green¬ 
house plants, and Banksian Medals to Mr. C. Brown, of Slough, for Tulips and Heartsease ; 
Mr. Lee, of Hammersmith, for China Roses and Azaleas; Messrs. Colley and Hill, of Ham¬ 
mersmith, for Pelargoniums and Yellow Noisette Roses; Mr. R. Chandler, of Vauxhall, for 
Greenhouse Plants; Mr. G. Mills, gardener to A. Copland, Esq. for Flowers and Fruit; Mr. 
Niemann, gardener to P. C. Labouchere, Esq. for forced Apricots, Raspberries, Melons, &c. 
Mr. Waterer, for Rhododendrons and Azaleas; and Mrs. Colville, for Oncidium altissimum. 
The customary Meetings for June have not either been wanting in attraction; the Alstroemerias 
pulchella and pelegrina, Double Yellow Roses, Pamnies, Roses, Pentstemous, and Scarlet 
Sweet Williams, having been very conspicuous in the collections. Papers have been also read 
on the management of the Cactus, and on the means of obtaining abundant autumnal crops of 
the double-bearing Hautbois Strawberry. 
IV —MONTHLY horticultural calendar. 
FOR JULY. 
FRUIT DEPARTMENT. 
Budding Peaches, Nectarines, Apricots, &c. may now be performed ; for the system, see p. 259. 
Summer Pruning must now receive attention, a good sprinkling of fruit being left upon the 
trees till after the stoning season. 
Apple Trees have suffered much this year from caterpillars; those in webs, if not too abun¬ 
dant, may now be gathered off w ith the hand, and the tree * should be well washed with strong 
soap suds, by means of an engine. 
Pear Trees during this month are often infested with a number of small larvse, probably 
of the saw-fly family which feed upon the upper rind and pulp of the leaves. They may be known 
by the spotted and glutinous state of the leaves. To destroy them, add about a bushel of good 
quick lime to ten gallons of water, which must be stirred up for a day or two. After it is set¬ 
tled, use the clear liquor, working it on the tree either with an engine or syringe. Another 
small insect is prevalent this month, which mines in the leaf, but seldom materially injures the 
tree. It feeds till about August, and then retires into crevices of the wall where it passes into 
a chrysalis state, and the perfect fly appears in the June following. To destroy them, bean 
stalks or pieces of old woollen rag may be stuck in different parts of the tree, inducing them to 
take shelter therein. In winter, the shreds may be taken from the tree and boiled, previously 
to being used again. 
Plum Trees— Thin the fruit, and use them for tarts where they are too thick. Should the 
trees be infested with aphis, obtain some good soap suds, or dissolve one pound of common 
soap in twelve gallons of w^ater, adding two gallons of very strong tobacco water. With thi3 
mixture,syringe the trees, and they will soon disappear.
