are first attacked by insects. Plants in a vigorous healthy condition 

 rfepcl them to a great extent. 



Green fly is the greatest pest in the way of insects wo Iiave. It in' 

 creases so fast tliat in a short time after the first of them appoar they 

 are to be found in large numbers. Fumigating with tobacco is the most 

 effectual remedy for the destruction of this pest ; in fact, in our green- 

 hou.ses, is the only remedy. As soon as they appear, place the plants 

 under a barrel and place some burning tobacco stems beside them. As 

 soon as the barrel gets filled with smoke, lift out the burning coals, to 

 prevent too much heat, as it is heat, and not smoke which destroys the 

 leaves of tender plants. Heliotropes, salvias, and similar plants are easily 

 hurt with the smoke. Caution is, therefore, necessary, if any of them get 

 covered with fly, that smoking be done gently. On the morning after 

 fumigating, give the plants a good syringing, to clean off the insect.s. The 

 foliage of plants to be fumigated should be dry, as they are easily injured 

 lvhen wet. 



Red spider is the worst insect in number which gives us ti'ouble, and is 

 produced where the atmosphere is too dry and warm. In an atmosjihere 

 where plants are growing vigoi'ously, this insect is never seen. To get rid 

 of it, frequent syringing is needed. It appears generally on the under side 

 of the leaves ; is a small red insect and is not often known to be on the 

 plant until the foliage begins to get discolored by its ravages. Rose 

 leaves, when attacked by it, get brown on the under side and finally drop 

 off. The thrip is an active lictle fellow, generally doiiig his depredations 

 on the under side of the leaves. It is a long and slender creature, with' 

 very narrow wings, and proves very destructive when it once gets a foot- 

 hold. Fumigating with tobacco and washing the leaves are the best reme- 

 dies for its destruction. 



Scale or cocus is a common pest on a good many plants, especially 

 hard-wooded kinds, like oranges, oleanders, camellias and many others.. 

 It is to the superficial observer, stationary, but spreads rapidly, there being 

 a great many kinds of them — white, brown and black. The white is the 

 one which gives the most annoyance, being the most difficuft to wash off, 

 which is the only remedy for getting all the kinds destroyed. Use in the 

 water, when washing them off, plenty of soap and tobacco juice. Mealy 

 bug is a loathsome looking creature, something like the above, but has a 

 mealy covering looking like down. Washing and brushing with a soft 

 brush is the best way of getting rid of them. 



.Plants which are regularly washed and syringed are never much infest- 

 ed with insects of any kind and if any of the kinds mentioned alxjve first 

 make their appearance destroy them by this means before a foothold by 

 them is secured, and there is but little trouble in keeping them from doing 

 much injury. 



Worms in pots often give considerable annoyance to plant growers but 

 a little lime put into the water will expel them. Soot answers the same 

 purpose. — Ohio Farmer.
