These are but a few of the difficulties which I have

 It is built in the following manner: Select posts of

 the posts. Then take No. 16 galvanized iron wire and 

 put it on perpendicularly, twisting it around the lower 

 and upper bar, each wire being placed just where the 

 upright bearing shoots are to grow. It is well not to 

 put on the wires until the vines are ready for training, 

 and then lay down the arms by the side of the lower bar,
