PREFACE.. vil 



fe6ted with the canker, that difeafe may be feen oozing through 

 the Compofition and adhering to the outhde, like copper dull, or 1 

 ruff, of iron, and may be eaiily rubbed off with the hand. This 

 appearance I never could obferve on the application of any other 

 Compofition ; which confirms my belief that it acts as a ftrong 

 ftimulant. 



When the wounds in fruit trees are fo large as not to heal up in * 

 the courfe of a twelvemonth, I renew the Compofition annually,,, 

 which, on its application, invigorates the trees, and-feems. to have 

 the fame effect on them as a top-drefiing of dung has on land.i 



I have been folicited by fome of my friends to add a chapter * 

 on forcing Grapes, Peaches, and Nectarines; and to, give a de-.- 

 feription of a houfe for that purpofe ; but as it would fvvel 1 the 

 book to too great a fize, and as the fubje6l is fully treated I 

 of by many others, it feems unneceffary to fay any thing s 

 farther here, than jiift to obferve, that the method of pruning and 

 training recommended in this book is equally applicable to trees s 

 in a forcing-houfe as to thofe on a natural wall. When Vines are > 

 trained ftraight up the rafters of hot-houfes, they throw out a few 

 " eyes only at top, and all the reft of the branch becomes naked ; ; 

 but when trained in a.ferpentine manner, they break equally. 



Dwarf Peaches and Nectarines planted ki the pits of forcing- • 

 houfes mould be trained horizontally ; in which mode they will 

 produce much more fruit than when they are trained fan-fafnion. 



It muff, be obferved, that the Directions, &c. in the following 

 pages are calculated for the neighbourhood of London ; it will, 

 therefore, be neceffary to make allowance, in other climates, for 

 the earlinefs or latenefs of. their feafons, both with regard to the time 

 of fruit being in perfection, and alfo for planting, pruning, &c. 



For the information of thofe who are not acquainted with prac- 

 tical gardening, the following, explanation of what is. called 

 II eading-down is given. .
