work, by preventing any water from being unnecessarily 

 spilt in the house. The size of the pot will be regulated 

 by the person to suit the conveniences of the place. Water, 

 when applied either to the roots or foliage of the plants, 

 should be about the medium temperature of the house. 

 Where there are no cisterns, a tank or barrel might be in 

 the house, in which the water could stand for one night or 

 more, as is most suitable. When water is given without 

 being thus aired, it chills the roots, prevents a luxuriant 

 growth, injures the fresh and healthful appearance of the 

 foliage, and too frequently gives to all the plants a sickly 

 hue. 



OF INSECTS, THEIR DESTRUCTION, &c. 



In this department insects begin to increase by hun- 

 dreds, and too frequently their ravages are very obvious 

 before their progress is arrested. We will treat of those 

 which are most common, under their respective heads, with 

 their nature and cure, as far as has come under our obser- 

 vation. 



Jlphis rosse, of the natural order of Heiniptera, or what 

 is commonly known by Green Fly, Green Lice, &c., in- 

 fect plants in general, and are particularly destructive in 

 the hot-house to Hibiscus rosa-sin?nsis, tflsclepias, Crds- 

 sula coccinea, Lantdna, &c., and many other plants of a 

 free-growing nature. They attack the young and tender 

 shoots at the point, leaving a dark filthy appearance on the 

 foliage. Many remedies for their destruction have been 

 offered to the public by various writers, each equally 

 secure in his own opinion. Extensive practice alone can 

 show the most easy and effectual cure. Fumigating with 

 tobacco is decidedly the most efficacious, and in the power 

 of any to perform. Take a small circular furnace, made 

 of sheet iron, diameter at top twelve inches, and at bottom 

 eight; depth one foot, having a grating in it to reach with- 

 in three inches of the bottom, which will leave space for 

 the air to pass, and where the ashes will fall and be kept 

 in safety, having a handle like a pail to carry it with. 

 This, or any thing similar, being ready, put in it a few- 

 embers of charcoal, ignited to redness; take it into the
