         with  the  ratchet  wheels  to manually rotate the  ratchet
         wheels and reel, and a spring biased retractable latch plate
         14D for  releasably latching  the ratchet wheels  and reel
         when not being rotated. The free end 11B of the belt 11 is
         gripped and wound on the reel 14A and the belt is tightly
         cinched about the tree trunk by manually operating the le-
         ver 14C. A suitable ratchet buckle is commercially available
         from Ancra International LLC, Erlanger, KY.
           Referring again to figure 1, the preferred cable assemblies
         20 are made of galvanized steel aircraft cable and may be
         coated with clear, white, or orange vinyl. The first end 20A
         of each cable assembly 20 is looped through the lower loop
         eye 12B of each belt loop member 12, respectively, and se-
         cured with a conventional cable clamp 20B. The turnbuckles
         21 are commercially available zinc plated eye and eye type
         turnbuckles with a 3/8" thread diameter.
           Referring now to figures 4, 5, and 6, the second end 20C
         of each cable assembly 20 is secured to a ground anchor 30
         by a cable clamp 20B. A suitable ground anchor known as
         the “duckbill anchor” is commercially available from Fore-

         ground anchors are shown and described in U.S. Pat. Nos.   Bi-42Sn, in accordance with certain aspects of the present
         4,044,513 and 4,802,317, which are hereby incorporated by
         reference to the same extent as if fully set forth herein.
         Therefore the ground anchors are not shown and described
         in complete detail.
           The ground anchor  30 is a rigid metal  tubular member
         having an enclosed cruciform star point leading driving end
         30A and an open trailing end 30B with an out-turned lip
         30C on one side thereof and a cable eyelet 30D intermediate
         its ends on the side opposite the lip side and positioned rear-
         wardly of the center of mass of the member. Lateral ribs or
         wings 30E extend a short distance outwardly along opposed
         sides of the anchor member. As shown somewhat schemati-
         cally in figure 5, a driving rod R is inserted into the ground
         anchor 30 through its open end 30B and the anchor is driven
         into the ground in an upright position to the desired depth.
         As shown in figure 6, the driving rod is removed, and the
         cable 20 is then pulled upward to rotate the anchor 30 about   Figure 7: Cross-structure view of a core-shell solder wire with a core wire.
