 ground intended for planting. If it is a 

 poor mallow foil it is wrong, becaufe the 

 gravel muft be thrown up or there can be 

 no trench, and the little mould there is 

 will be loft, and nothing left for the trees 

 to ftrike roots in but gravel, mixed with 

 a fmall quantity of earth, fo finall that it

 trees were planted according to the direc-

 quence to trench; for to make even a very 

 mallow trench there muft be a good deal of 

 clay thrown up. If the earth be mixed 

 with the clay it will be loft ; if laid in the
