.It is alsofto'be stated that the barsshould be made of different weights, the heavier bars to be used at the bottom or forms and said barsdecreasing in weight as they are used at higher altitudes.

I have also found that it is entirely practical to construct a wedge bar by: welding short pieces of angle iron to a steel bar and then shaping the projecting flange of the angle iron as desired. I

This particular structure with a slight modificationcan be employed with equal facility and advantage in connection with wire ties orsheet metal ties- ,7 The embodiment connection with wire ties.
