FRUIT TREES. Chap. III. 61 



by fitting one end under the coping & placing the hook against the other end, they 

 simultaneously adjust the projection of the hook from the wall & its distance from the 

 coping. When some of the hooks in the row are positioned properly, it's usually sufficient 

 to align the rest of them by eye. 



Nola 1° . The hooks should be staggered; i.e. each hook in a row should be at the 

 mid-point relative to two hooks in another row. 



Nota 2° . On walls only six to eight feet high, where the rows of hooks aren't far 

 apart, hooks in the same row can be placed four feet apart from one another, instead of 

 three feet. 



A series of horizontal laths is set on each row of hooks and secured by binding 

 them with annealed iron wire. The beveled edges of the laths are fitted to one another, 

 joined together, & tied with two or three links. 



On the rows of laths closest to & farthest from the coping, divisions eight inches 

 apart ( i.e. the distance from one vertical lath to the next) are marked with chalk or 

 blackened stone. Initially vertical laths or uprights are placed on every sixth division and 

 are attached to the horizontals. Then the rest of the horizontal laths are run between the 

 wall & these uprights in between the rows of hooks. They're tied onto the uprights nine 

 inches apart corresponding to the divisions marked on the wall, and they're joined and 

 assembled. Finally, the rest of the uprights are put in place, & the vertical & horizontal 

 laths are tied together everywhere that they intersect. 



A trellis can be constructed in a more mechanical way without having to mark any 

 divisions on the wall or on the laths. One takes a small board about ten inches long
