f l'' PJ.ANTS are of a ^ood vifjoroiis srowtli all leaves will he i)erfcet, ami if any of lliem hcKin to

'1 '** ®*ti(l ‘-It is only a few green Hies,” wlierea.s that few means thonsamls, ami every dav thev 
are allowed to go on feeding so much, that the plants are heing eaten up alive. Therefore, to 
grow ])lants to perfection, always have suHieient fumigating material in rcadincs.s, and aiiplv it’on 
their very first ai)])earanee. ‘ ' 
I’erhaps there is no operation in the garden to he performed more hewildering to the amateur than • 
the process of fumigating his green-house to rid the plants of the green fly or aphis, vet few things are 
more easy to he, aceompli.shcd. Onr houses are 100 feet long. 12 feet wide, and 8 feet high. One of 
them requires 4 Ihs. of our specially jirepared tohacco rag or paper, and if voii can hv thesiT dimensions 
calculate the space of your own house, you can send for or use thee.vact (|uantity required. Now come.s 
the secret, and the art or skill of carrying it out, that is, to kill all the insects without injurv to the 
plants, and to do this it requires every attention just at the particular time. Close and cover up all 
apertures, for so much that escajtes is so much money wasted ; the material should he modcratelv drv, 
that is to .say. not quite drv or wet, huthy no means water it. Lay it on hrieks or other tminfiam'mahle 
floor, iirocnre a red-hot cinder and wrap it round with a piece of the cloth or paper, to he reiieated at 
tlistanccs of (! feet in length of house ; hy this time the house will he partially full : aild other pieces, a.s 
there is a just proportion of saltpetre to cause it to consume itself. Lay the remaining material aloii" the 
pathway in a longitmlinal form, .so that they may touch, and one will ignite the other, .so as to kecp'iip a 
gentle fume for a long time. Be sure and not let it flare. No plants like smoke, and the less they are 
.suhject to it the hotter; hut when it hecomes necessary it must he done without causing them the least 
injury, and when ])lants have made quick tender growth from being kept clo.se in heat and moisture, 
they will ho found to ho much more liable to injury, and a longer time must he taken ; hut when plentv 
of air has been given, c.xi)osure to sun and wind, '&c., then a stronger and quicker dose can he given’. 
Ferns, Tropieolums, Verbenas, and Heliotropes arc all very susceptible to injury early in the .season, and 
even the juire tohacco will injure them if applied in too great a quantity at once. The densitv of the 
smoke must he only to admit of 3 to 5 feet heing seen in the greenhouse through the glass, 8 feet for tender 
plants. A very mild quantity of fume will kill the young fly— the ditlieully is to kill the old one.«, 
and so long as they have strength to move, so sure they will soon recover and' multiplv by thousands! 
Nowhere does the old adage illustrate itself more plainly than in fumigating — •‘What "is worth doing! 
is worth doing well." We therefore always make it a ])oint to commence in the evening, and give 
another and stronger dose early in the morning, and it is surprising what a saving it is to give them 
the double dose, or even the third Keep the house firmly closed as long as possible, then svringe. if 
weather permits, tvith clear rain water, standing two or three cans of well water in the house, as that 
has a wonderful (piick effect in dispelling any ohjectionahle odour. If all this is carried out as directed, 
green fly would become scarce, and our valuable plants much more beautif id, and of course sati.sfactorv! 
When the proec.ss is going on, be jiarticnlnr that the fumes are not a-scending in too great a volume; if 
so, when it rebounds from the glass, it will be sure to injure the foliage. What is wanted isaregu'lar 
house full of mild smoke, and this keiit up from two to four hours, choosing dull still weather : .should 
the sun shine, a shading mu.st he applied.
