water twelve gallons. Divide the water into equal parts : put 

 six gallons into a barrel (which should be only used for this 

 purpose) ; put the soap in the barrel with the water, let it 

 be well stirred till it is quite dissolved ; then add to it the 

 mushrooms, after they have been slightly bruised : take the 

 remaining six gallons of water, put it into a kettle to boil ; 

 put the whole quantity of sulphur into a coarse cloth, tie it 

 up and fasten to it a stone, that it may sink to the bottom of 

 the kettle ; put the nux vomica likewise into the kettle to 

 boil ; thirty minutes is the time it should be kept boiling ; 

 keep it well stirred with a stick, and let the sulphur be well 

 squeezed out, that it may unite to the lather. The water, 

 when taken off the fire, is to be poured into the barrel with 

 the before-mentioned soap and mushroom-water. It is to be 

 well stirred every day with a stick, until it gets incorporated 

 altogether, and the mixture becomes fetid ; it is necessary to 

 stop the barrel while you are stirring it. In using it, sprinkle 

 on the ground, or eject it with a common syringe. When all 

 the water has been made use of, the sediment should be 

 thrown into a pit and covered over, lest any thing eat of it. 

 If you deem this receipt deserving a place in your valuable 

 miscellany it is at your service. 



I am, Sir, &c.

 stroying the Green Fly and other Insects. By Mr. Thomas 

 M'Laurin, Gardener, Bunny Park, Nottinghamshire. 



Sir, 



In the present dry season, so favourable to the production of 

 green fly that their numbers are almost unprecedented, the 

 following method, which I practise, for their destruction, may 

 perhaps not be unimportant to some readers of your valuable 

 Magazine. 



I procure, from the tobacconist's, liquor expressed from 

 tobacco, to every gallon of which I add five gallons of water ;
