Tandem Monoplane Glider
By George F. Mace
The monoplane glider illustrated has better fore-and-aft stability than the biplane, is lighter in proportion to the supporting surface, simpler to build, and requires very little time to assemble or take apart. The material list is as follows:

| 4 | pieces of bamboo, 14 ft. long, tapering from 1-1/2 to 1 in. |
| 8 | pieces of spruce, 1/2 in. thick, 1 in. wide, and 3 ft. long. |
| 8 | pieces of spruce, 1/2 in. thick, 1 in. wide, and 2 ft. long. |
WINGS
| 4 | main-wing bars, spruce, 3/4 in. thick, 1-1/4 in. wide, and 18 ft. long. |
| 8 | wing crosspieces, spruce, 3/4 in. square, and 4 ft. long. |
