THE FLOEAL WOELD AND GARDEN GUIDE. 



able in make and material. It consists of a large iron cylinder, 

 fixed upon four legs, with a large spout for the egress of the smoke. 

 The inside is fitted up with a stout wire basket to bold the fumi- 

 gating material, and is made to revolve for the purpose of creating 

 a current of air by means of bevel gear set in motion from the 

 handle outside. In the bottom of the cylinder there is a large 



opening to admit air, and also 

 to allow the ashes to escape ; 

 therefore any clogging by 

 means of the ashes is impos- 

 sible. In setting it to work, 

 twist a piece of dry brown 

 paper, and, after it is lighted, 

 place it in the cage, and then 

 fill with the tobacco or what- 

 ever else may be used. The 

 materia], put immediately over 

 the burning paper, should be 

 rather dry, to insure its ig- 

 niting quickly ; but the re- 

 maining portion must be used 

 rather moister than with the 

 flower-pot and bellows. 



The handle should be 

 turned gently during the time 

 the cage is being filled, and 

 when a sufficient quantity of 

 material is put in close the 

 lid, and by continuing to turn the handle steadily, dense volumes of 

 cool smoke will be emitted, which will fill a large house in a few 

 minutes. It is not necessary to go inside the house at all, as a half 

 trick can be removed from the wall, and the end of the spout in- 

 serted in the opening. The occupants of the houses will be fumigated 

 quite as effectually as they would be if the operator and machine 

 were inside, an advantage which cannot be over-estimated, as being 

 in a house filled with tobacco smoke for a quarter of an hour or 

 more is certainly one of the most disagreeable experiences connected 

 with the management of the garden. 



Tobacco water is sometimes to be preferred, especially if only a 

 few amongst many trees are infested with green-fly. To prepare it 

 procure the strongest shag tobacco, and pour boiling water on it at 

 the rate of one gallon of water to two ounces of tobacco. When 

 cold and clear, apply with the syringe or dip the shoots into it. 



Mildew is, without question, an evidence of debility, but it may 

 be the accident of the season, and not the fault of the cultivator. 

 This plague usually follows close upon a time of drought or of ex- 

 cessively hot days, followed by excessively cold nights, with a clear 

 east wind and a sky wonderfully blue. The plant is debilitated by 

 sudden, and extreme, and oft-repeated changes of temperature, and 

 mildew is the result. Here again, whatever restores the vigour 

 of the plant makes an end of the mildew; but. as a matter of fact,
