USE OF TOBACCO WATER. 303 



find, that as the demand increases, the tobacconists weaken It ought to b© 



what they send out ; and care must therefore be taken, that ^j^ 1 " y 



it be sufficiently strong when used, which may be known by 



its giving the water a tolerably brown colour. I have found 



sometimes a wine-glass full sufficient for a gallon of water ; 



at other times, what I have procured has been so much di» 



luted by the tobacconist, that it has required a pint to give 



a proper strength to that quantity. I was last summer 



greatly annoyed by the red spider on those trees that had a Red spidtr. 



direct south aspect. The minuteness of the insect, and 



being so securely sheltered underneath the leaf, prevented 



several of ray applications from taking a due effect; but on 



watering my trees with an engine for about ten successive 



evenings, very forcibly, and immediately after being so wa«- 



tered giving them whilst wet a sprinkling of tobacco water, 



about three of those evenings, the trees recovered and ripened 



their fruit very finely, 



I hope next summer to have it in my power to inform you Apple trees 

 of the result of an experiment T am now making, with respect trans P lante( *' 

 to transplanting apple trees from an orchard near me, that 

 is about to be converted to some other purpose, Havin«- 

 purchased as many of the trees as I was desirous of remov- 

 ing, 1 have newly planted out about forty of them, several 

 of which bare each a hogshead of eider last year, and hare 

 done it in many previous seasons. As I have paid great at> 

 tention to the preservation of them, I have little doubt of 

 success. But as it cannot yet be ascertained, I shall defer 

 enlarging upon the subject till I have the pleasure of ad- • 

 dressing you again, tn the mean time I remain with great 

 respect, 



Your most obedient servant,
