nar) care taken to deftroy t!-,em. Thev have alfo at- 

 tacked the Orange-trees n many gardens near Lomlont 

 and have done thera incredible damage ; but I do not 

 find they will endure the cold of our climate in winter, 

 fo that they are never found on fuch plants as live in the 

 open air. The only method I have yet been able to dif- 

 cover for deftroying thefe infects, is, by wailiing the 

 leaves, branches, and ilemsjcf fuch branches as they 

 attack, frequently with water, in which there has been 

 a llrong infufion of Tobacco-dalks, which I find will 

 detfroy the inie'^s, and not prejudice the plants. But 

 this method cannot be praftifed on the Jlnanas plants, 

 becaufe the infers will faften themfelves fo low be- 

 tween the leaves, that it is impoffible to come at them 

 with a fponge to wafli them off; fo that if all thofe 

 which appear to the fight were cleared off, they will 

 foon be fucceeded by a frefh fupply from below ; and 

 the roots will be alfo equally infefted at the fame time. 

 Therefore, where-ever thefe infeffs appear on the 

 plants, the fafefl: method will be, to take the plants 

 out of the pots, and clear the earth from the roofs; 

 then prepare a large tub, wl^.ich fliould be filled with 

 water, in which tliere has been a ilrung infufion of 

 tobacco-fialks; into this tub you fliould put the plants, 

 placing fome llicks crofs the tub, to keep the plants 

 immerfed in the water. In th.is water thev fliould re- 

 main twenty-tour h.ours ; then take them out, and 

 with a fponge wafli off all the infects from the leaves 

 and roots, which may be eafily effj£led when the in- 

 fects are killed by the infufion ; then cut off all the 

 'fmall fibres of roots, and dip the plants into a tub of 

 fair water, wafliing them therein, which is the moft 

 effectual way to clear them from the infefts. Then 

 you fliould pot them in frefli earth, and having 

 ftirred up the bark-bed, and added foine new tan
