A large collection of beautiful bone implements (see fig. 31)—needles, awls, tubes, and dirks—rewarded the work at Spruce-tree House. Some of these show the effects of fire throughout their length, while others are smoked only at one end. When unearthed, one of these dirks was still in the original sheath of cedar bark (fig. 32).

Most of the needles, bodkins, and awls are made of bones of birds or small animals. These were apparently rubbed down and pointed on stone implements or on the sides of the cliff, where grooves are often found (fig. 33).

Several fine bone scrapers (figs. 34, 35) were dug out of the débris covering the floors of the rooms. These are beveled to a sharp edge at one end, the trochanter of the bone serving as a handle.
