Among the many instruments essential to the proper management of a garden, this invention by Mr. Fry promises to be one of the most useful, alike indispensable to the cottager as to the manager of the largest establishment. Through the kindness of a neighbor, we have had an opportunity of trying some experiments with the machine, and we find it admirably adapted for the purpose intended, as well as for fumigating raent, a row of Peas, a score of Heaths, a frame of Cucumbers or Melons, or a house of Vines may be covered with sulphur in a few minutes, and that not in superabundance in one place, and none in another, but it is equally distributed like fine dust, and so as not to be offensively perceptible on the plants. Sulphur, and more especially sulphur vivum - the waste, is very cheap, if bought at the manufactory; and we have reason to believe that the Hop growers of Kent intend to avail themselves of this machine to destroy the mildew upon the Hop plants. It is necessary that the machine as well as the sulphur be perfectly dry when used, or it is liable to clog.

For distributing snuff to destroy the Aphis on wall trees, and also for quick lime for the Turnip fly, this machine might be used with advantage.

It is true, we have not been in the habit of using sulphur so extensively in garden management as has been necessary; but now we have got this machine, and know at the same time sulphur sufficient for the supply of a large garden may be purchased for a few shillings, we see no reason, why Peach trees, Peas, and many other crops should be allowed to draw out a miserable existence, when the enemy that kills them can be destroyed by a few puffs of this instrument. One of the best flower gardeners in the country, Mr. Beaton, of Shrubland Park, uses sulphur among his flower beds, as Verbenas, Calceolarias, etc, to destroy the mildew, which upon some kinds, late in the autumn, is very troublesome; and we have no doubt he will regard this machine as a perfect boon to him, as will every other gardener who procures it. With it, all the beds in an ordinary flower garden might be dusted in less than an hour, and without being rendered unsightly, as they must be when sulphur is thrown upon them by the hand.

When used as a fumigator, the tobacco is placed in a vase provided for the purpose, which can be attached to the machine in a few seconds; thus there is no chance of the ignition of the sulphur, or the generation of sulphurous acid gas, wh ch is so destructive to vegetable life, and which is so much dreaded by some gardeners who do not know the machine. In fumigating, this machine discharges the smoke much colder than Brown's instruments, as a portion of cold air is drawn into the tube and mixed with the smoke with each revolution of the fan.

The only fault we have to find with it is, that it is not manufactured sufficiently strong, but when properly made, we doubt not, it will last for a number of years. It can be procured from Mr. Fry, gardener to Mrs. Dent, Manor House, Lee, Kent. - Gard. Mag. of Botany.
