In 1881 some very important additions to the National Museum were made, from the mounds of Tennessee. These include a great wealth of objects in shell. From the McMahan mound at Sevierville, Tenn., there are a dozen shell pins, all made from the _Busycon perversum_. The entire specimens range from three to six inches in length; two are fragmentary, having lost their points by decay. In shape these objects are quite uniform, being, however, as a rule, more slender in the shaft than the average pin. The heads range from one-half to one inch in length, and are generally less than one inch in diameter. They are somewhat varied in shape, some being cylindrical, others being conical above. The shaft is pretty evenly rounded, but is seldom symmetrical or straight. It is rarely above one-half an inch in diameter, and tapers gradually to a more or less rounded point. The groove of the canal shows distinctly in all the heads, and may often be traced far down the shaft. In a number of cases the surface retains the fine polish of the newly-finished object, but it is usually somewhat weathered, and frequently discolored or chalky. These specimens were found in the mounds along with deposits of human remains, and generally in close proximity to the head; this fact suggests their use as ornaments for the hair. Two illustrations are given in Plate XXX. Fig. 1 represents a fine example, six and a quarter inches in length. The head is deeply grooved, and is apparently cut from the middle part of the columella, the shaft being formed from the spine-like basal point. The spiral canal, which is clearly defined, makes but one revolution in the entire length of the pin. In Fig. 5 a somewhat similar specimen is represented. Two fine specimens come from a mound on Fain's Island, Tennessee River. The larger one is made from the columella of some heavy shell, probably the _Strombus gigas_. The head is cylindrical, and the shaft large, but imperfect. The smaller is a little more than two inches in length, the head being small and conical, and the point more than usually blunt. Another specimen was obtained from a mound at Taylor's Bend, near Dandridge, Tenn. The head is almost spherical, and the point broken off; the whole surface is new looking and highly polished. A number of bone pins pointed at both ends were obtained from Fain's Island, besides many perforators and other well-made implements of bone.
