It appears from these analyses, that the Thomery soil contains 

 a greater proportion of silica, alumina, lime, and magnesia, than 

 the soil in the Society's Garden ; but nearly one-third less oxide of 

 iron, and only one-half the quantity of organic matters. The latter 

 circumstance proves that the soil is not highly manured. The 

 manure preferred consists of equal portions of horse-dung and 

 cow-dung mixed. The dry soil is easily moistened through- 

 out. 



Vines are also trained, en cordon, against low espaliers in the 

 ground forming the central plot of the respective enclosures. 

 In some seasons the fruit from these is said to be excellent in 

 quality ; but wind and rain often render it unsaleable, except as 

 inferior produce. Some of the espalier vines were 60 years 

 old, and were even partially overrun with moss. Against a wall 

 16 feet high, vines were trained en palmette, as at Fontaine- 

 bleau. 



Outside the walled enclosures, in the open ground approaching 

 the forest, vines were observed cultivated according to the vine-
