| Name | Hackberry (Celtis occidentalis) |
| Type | Hardwood. |
| Other Names | Also known as sugarberry, nettle tree, bastard elm, hoop ash and hacktree. |
| Sources | Grows in eastern half of United States and southern Canada. |
| Appearance | Straight or sometimes interlocked grain and fairly uniform texture. Yellowish gray to light brown heartwood and pale to greenish yellow sapwood. |
| Physical Props | Soft and moderately heavy with low strength, stiffness, shock resistance and decay resistance. Medium movement in service. |
| Working Props | Works easily with machine or sharp hand tools. Good carving wood. Pre-drilling recommended for screwing or nailing. Glues, stains and finishes well - natural finishes especially. |
| Uses | Resembles ash and elm and has similar uses, such as: crates, farm implements, carving, athletic goods, millwork, and interior cabinetry. |

| Sources | APPEARANCE: Uneven, frequently spiral grained with medium to coarse texture. |
| Appearance | Uneven, frequently spiral grained with medium to coarse texture. Buff to light brown color, heartwood indistinguishable from sapwood. |
| Physical Props | Light and soft with low ratings for stiffness, bending and compression strength, shock resistance, and decay resistance. |
| Working Props | Works reasonably well with machine or hand tools although it is brittle. Glues satisfactorily. Pre-drilling recommended to prevent splitting when screwing or nailing. Accepts paint, stains, varnishes, and polishes well. |
| Uses | Used mainly for building construction, as well as boxes, crates, pallets, casks, shingles, siding, and pulpwood. |
| Name | Western Hemlock (Tsuga heterophylla) |

| Sources | Grows in western United States and Canada. |
| Appearance | Straight and even grained with a fine to medium texture. Whitish to light yellowish brown color, heartwood not distinct. |
| Physical Props | Light and soft with moderate stiffness, bending strength, compression strength, and steam bending, low shock resistance and decay resistance. Good dimensional stability. |
| Working Props | Works easily with machine or hand tools (slightly better than eastern hemlock). Accepts paint, stains, varnishes, and polishes well. Glues quite easily. Pre-drilling recommended for screwing and nailing (but less apt to split than eastern hemlock). |
| Uses | Used mainly for building construction. Also used for interior and exterior joinery, doors, flooring, vehicle bodywork, turnery, broom handles, boxes, crates, pallets, cooperage, furniture, ladders, plwood, paneling, veneer, and pulpwood. |
