 the edge of the Jjiles, affording altogether a support of at least 

 two feet six inches wide. Upon this is fixed, when occasion

 necessary, a piece of thin plank. The bitumenised felt is 

 stretched on frames of wood, about ten feet in length by eighteen 

 inches in width, the felt being fastened to them by means of 

 small nails. These frames are chiefly used when the Grapes are 

 perfectly ripe, which is generally about September 15, or when 



there is danger of the fruit being spoilt by 

 heavy rains. Formerly, before these methods

 sufficient."
