That system of holding great public meetings for the purpose of exhibiting Horticultural produce, which originated more than thirty years ago with the Horticultural Society Of London, after crossing the Atlantic, and spreading through all the more civilised Continental States, has at length reached Russia. It appears that in the year 1850 the first meeting in that country was held at St Petersburgh by the Imperial Economical Society, under the presidency of the Prince Duke of Oldenburg and Prince Basil Dolgorouky, on which occasion prizes were distributed to the amount of something more than 10,000 roubles, (1,600/). Since that time these assemblages seem to have become fashionable, for we hear of one at Tiflis, formed by Prince Woronzoff; and of another at Moscow, in 1868. An account has been given by M. Masson, from whose report we collect the following interesting facts:

The exhibition in question lasted for a fortnight; on every alternate flay it was opened gratuitously, on the others admission was obtained by payment. Each free day witnessed the presence of from 80,000 to 85,000 visitors. The place in which the meeting was held was the Government riding school, a building some hundred yards long. The objects of exhibition were so disposed in the interior that the visitors were able to enter at one door and depart at another, inspecting every thing in their passage without ever passing twice over the same ground. The exhibition was classified by the inspector of the Imperial Agricultural School, and each separate division was placed in the charge of one of the pupils of the school.

Two parallel rows of tables extended from end to end of the building, and were occupied by what may be called industrial produce. In the center was placed a collection of agricultural implements, exhibiting the most rude and primitive by the side of machines of the newest and most improved construction.

In the middle of the whole stood a "monumental clock" which indicated at the same moment the hour of the.day at' each of the four extreme points of the vast Russian empire. This chef dceuvre of clock-work was embosomed in a rich collection of exotics of various kind9, skillfully grouped and furnished by M. Fintklmann, one of the principal Horticulturists of Moscow. Adjoining the mass thus produced stood groups of plants from all countries, cleverly set off with Dahlias in pots. Among them were some extraordinary specimens of Strelitzias, Dracaenas, Pan-danus, Musa, Ac, together with finely grown Orange trees, and a Sweet Bay with a single clean stem supporting a head 8 yards round. "Never," says M Masson, "in all my travels did I behold such a magnificent specimen as this".

At the four angles of the central square, which was filled with ornamental plants, were placed four large gilt frames, each enclosing about eight square yards of space. Two of the frames contained, arranged with great taste, the most remarkable specimens of kitchen garden produce then in season; the two other frames were in like manner filled with very fine collections of fruit Among these fruits were magnificent specimens of the beautiful transparent Apples of the Crimea, and many varieties of Pears, the size of which was surprising when it is considered that the climate of Moscow, the Pear tree is a greenhouse plant. These exhibitions of fruits and vegetables were the admiration of every body; and the plan, M. Masson thinks, might be advantageously introduced into France. That they were really arranged with great taste we can readily believe, when we call to mind the skill with which the Russian agricultural produce was displayed in our own Great Exhibition in Hyde Park.

The whole exhibition at Moscow was bordered by a line of fruit trees and ornamental plants, such as grow out of doors in France, but must be cased up in a Muscovite winter. Aniong them Peach and Apricot trees of an extraordinary size for plants whose roots were cramped in wooden boxes. Willows, too, were there of many kinds, clipped into round heads, and a Poplar which M. Masson, whose botany is more rusty than his gardening, calls Populus Blagovroney.

The reporter speaks in high terms of the excellence and variety of Muscovite vegetables, the size and beauty of which he says did honor to the skill of the Russian market gardeners, who do not suffer by comparison with those of Paris. He was particularly struck with the white and black Radishes from the Caucasus, some of which are a full yard long, and unknown in Europe.

Among the cereal grains there was a most interesting variety; and it was curious to compare the tiny Wheat of Archangel with the magnificent Corn from Bessarabia. - The oleaginous plants included one called Navet de Derbend, the seeds of which yield an extraordinary quantity of oil Among textile plants were exhibited a perennial Hemp, and a wild Siberian Flax.

The forest-tree exhibition was one of high interest Everything was there which the Russian territory grows, even the trees of Caucasus, sent, as M. Masson silly hints, by the military Governor of that an conquered country. Each tree seems to have been exhibited in the following manner: - 1, its seeds; 2, its timber, carefully polished to bring out what carpenters call the figure; and 3, a dried branch in flower and fruit Some similar plan was adopted with all the plants belonging to rural economy.

Among miscellaneous matters we find recorded great roots, more than three feet long, of the Statice ta'arica, used by Tartarian tanners under the name of Kierrae, and containing 22 per cent. of its weight of pure tannin; all sorts of objects manufactured out of bark, rushes and straw, among which figured straw head-dresses, and straw boots with leather soles, said to wear very well; and finally preserved fruits, fermented liquors, specimens of earth, both arable and fit for pottery or other purposes, textile materials, wool, and silk, the latter in great abundance and of great beauty.

Such is said to have been the great exhibition at Moscow in 1853, from which we English should borrow some useful hints. It is evident that tinsel was not there allowed to displace the more precious metals. - Gardener's Chronicle.
