TOBACCO PAPER 



Saturate paper with a decoction of tobacco, and 

 burn it. 



TOBACCO WATER 



Is usually made from tobacconists' liquor, made 

 of ammonia and the acrid oil of the plant. To 

 every gallon of this, five gallons of water should be 

 added. 



This mixture is best put on with Read's Garden 

 Syringe, and may be sprinkled over the trees, care- 

 fully wetting all the leaves. It should only be 

 done in the hottest sunshine, as the effect is 

 then much greater than it is in dull weather. 



TRENCHING 



Johnson, in his Dictionary, advises : ' Begin by 

 taking out a trench two spades deep and twenty 

 inches wide, and carry the earth to the opposite 

 end to fill up and finish the last ridge. 



' Measure off the width of another trench ; then 

 stretch the line and mark it out with the spade ; 

 then proceed in this way till the whole of the ridges 

 are outlined, after which begin at one end and fill 

 up the bottom of the first trench with the surface 

 or top spit of the second one ; then take the bottom 

 spit of the latter and throw it in such a way over 

 the other as to form an elevated sharp-pointed 

 ridge.'
