160 Improved Mode of Growing the Pear. 



the trellis to within six inches of the ground, is not a common one, 

 though very desirable where the erect mode of training the shoots 

 is practised. The reader will readily perceive that this system 

 combines the advantages of the cordon and the large tree. 



Of course many other forms, or any form, may be used with this 

 system of trellising, with slight modifications to suit different kinds 

 of trees or different forms. The double trellis, shown by Fig. 36, 

 is simply a modification of the preceding, and very desirable where 

 space is limited, and indeed for its economy, for one set of uprights 

 support the two sets of wires simply by using cross bits of iron 

 about 1 8 inches long, and at the desired distance apart. However, 

 the engraving shows this at a glance. This double form is ad- 

 mirable where it is desired to protect the espaliers. I once saw this 

 efficiently done by allowing the uprights to rise a little above the 

 upper cross-bars and then using iron rods so as to form a span at 

 each upright. The iron rods were projected about a foot beyond 

 the line of training wires. Through these rods galvanized wires 

 were strained so as to form a slender framework over the pears, and 

 on this was spread protecting material in spring.
