these two causes could only arise from the difference in the 

 width of the respective projections above them. 



In the Peach gardens at Montreuil near Paris, a projec- 

 tion of four or five inches is universally adopted ; and the 

 Comte Le li eur, the author of La Pomone Francoise, attri- 

 butes the failure of the crops of Grapes and Peaches in the 

 vicinity of Paris, more to the want of sufficient projection in 

 the coping than to any other cause. In page 78 of the 

 work he remarks, that the copings to all the walls of the 

 gardens in the neighbourhood of Paris have little or no 

 projection, while those of Thomery* have a projection of 

 ten or eleven inches over walls which do not exceed eight 

 feet in height. 



Induced by all these considerations I resolved to try the 

 experiment of a projection of nearly a foot in my new wall, 

 which has fully answered my expectation. I have annexed 

 a section of the wall, which I hope will make the following 

 explanation sufficiently intelligible. 



* Thomery is a village near Fontainebleau, where the finest Grapes are chiefly 

 grown, and which are so .well known in the Paris markets as Les Raisins de 

 Fontainebleau. The success of the inhabitants of Thomery in the cultivation of 

 Grapes upon these low walls with projecting copings, is well described in the 

 work above quoted.
