The pear trees for these dwarf walls should be 

 grafted on quince stocks, and trained horizontally. 

 They may be planted five feet apart at first, and when 

 their branches meet they should be interlaced, as in 

 Fig. 10, and if necessary-—*. e. y if the shoots be long

If, owing to the soil being rich, the trees are 

 inclined to grow vigorously and not bear, they should
