I7O THE FORCING GARDENER. [fi. I. 



fifteen guineas, including fpars, cords, and 

 pullies. 



The manner in which it was applied is 

 this : The canvas was made into three 

 equal iheets, which were joined together 

 every feafon when put on, and unjoined 

 when laid afide ; fpars or rafters of two 

 Inches fquare were placed at the diftance 

 of four feet from each other, their upper 

 ends being joined clofe to the copping, 

 and their under ends to a ftake drove into 

 the border, at the diftance of a foot from 

 the wall. Thefe were alfo made to remove 

 at pleafure ; pullies were fixed to the top 

 of each fpar, and the canvas hoifted there- 

 to by cords a little ftronger than garden 

 line. At firft I clewed it at top^ but, a 

 ilrong gale of wind having almoft tore it 

 from the wall, I contrived to clew it at 

 bottom, at the diftance of a foot from the 

 ground. Two people can uncle w and hoi ft, 

 or let down and clew, the whole in fifteen 

 minutes. 



When nets are to be ufed, they ihould 

 be doubled, in fuch a manner as to render 

 the mefties as fmall as poflible ; and fhould 

 be fupported from the wall about a foot by 



hooked
