ON VINEYARDS. 



be protected from spring frosts, by applying the 

 boughs of trees, particularly evergreens. The 

 grapes also, let me observe, would be greatly 

 benefited by the reflection of the soil under- 

 neath. 



When Vines are intended to be planted on the 

 steeps of hills, and on the sides of rocks, the 

 ground should be prepared and formed in the 

 manner of steps, as in plate v. 



The Vines should be planted near the angle a, 

 and trained by stakes upwards, from a towards b. 



It will be absolutely necessary that the ground 

 should be lower at the angular point a, of every 

 step, than at b ; for without this care, the Vine- 

 plants would lose the advantage of such rains 

 as fall hastily and perpendicularly. 



It is easy to conceive what advantage Vines 

 would gain from a situation thus planned, since 

 the back from a to b would be nearly equal to 

 a wall. 



The expense attending the formation of the 

 ground cannot be very considerable. The work 

 should be begun at the top, and the soil taken 

 out should be thrown down the hill. 



I should have observed, that it would be 

 further beneficial to have a little good soil put 

 in at the angles before the Vines are planted : and 

 also, that all hills of a southern aspect, and com- 

 posed of either slate, gravel, scaly rock, or lime- 

 stone, are very proper to be planted with Vines.
