Claim 8

The structural member of claim 3 wherein the upper end of each uppermost tube further comprises cap means for containing the soil within the tube.

Claim 9

A wall comprising a plurality of horizontally-adjacent pillars, each pillar comprising at least one substantially smooth, linear tube, each tube filled with soil, each tube made of a material having sufficient tensile strength to retain the soil in pillar-like configuration, each tube positioned substantially upright having an upper and a lower end, a minor portion of each tube extending downward into the soil immediately surrounding the lower end of the tube, a first of said horizontally-adjacent pillars having a substantially circular cross-section, each pillar immediately adjacent to the first pillar having a waisted cross-section, and each pillar immediately adjacent to any waisted cross-section pillar having a substantially circular cross-section.

Claim 10

A wall comprising a plurality of horizontally-adjacent pillars, each pillar comprising at least one substantially smooth, linear tube, each tube filled with soil, each tube made of a material having sufficient tensile strength to retain the soil in pillar-like configuration, each tube positioned substantially upright having an upper and a lower end, a minor portion of each tube extending downward into the soil immediately surrounding the lower end of the tube, a first of said horizontally-adjacent pillars having a substantially circular cross-section, each pillar immediately adjacent to the first pillar having a waisted cross-section, and each pillar immediately adjacent to any waisted cross-section pillar having a substantially circular cross-section.
