Art. IV. On the destruction of the Red Spider. 

 By J. W. Russell. 



A CERTAIN remedy for the vile insect, known by the name 

 of Red Spider^ no matter whether it has made its appearance 

 on the grape vine, peach tree, or any other tree or plant that 

 is grown under glass: sulphur, will destroy them, used in 

 the follow'ing manner: — After syringing the trees or plants 

 with water, as thoroughly as it is possible so to do, in the 

 evening, when the sun is leaving the glass, fill half a dozen 

 saucers or more, (according to the size of the house,) with 

 sulphur, and place them on the top of the flues, or pipes, if 

 flues are not used, ten feet apart, and start the fires; the heat 

 of the flues or pipes will heat the sulphur, and the vapor will 

 rise and fill the house completely full, so much so that in the 

 morning you will smell it quite strong, when you enter the 

 house: by following up this method a w'eek or ten days, the red 

 spider will make its exit. A dry heat is the red spider's ele- 

 ment, and they make rapid progress if this is not coun- 

 teracted by moisture and sulphur, which completely de- 

 stroys them. J. W. R.

We can attest to the certainty of Mr. Russell's plan for 

 destroying the red spider, one of the most destructive insects 

 which infests green-houses, hot-beds, and hot-houses; — sul- 

 phur and a plenty of moisture are the only things which have 

 ever enabled us to get rid of this ])es\..—Ed.
