bushed at one end, but narrowed about the middle by the shape of the 

 boring-tool, the workman being satisfied with any perforation that would 

 permit a string (commonly a sinew) to pass. An irregularity of perfora- 

 tion in which the two parts are not in line is common in perforated stone 

 beads, and often to such an extent as to forbid the passage of a needle. 

 The smallest of the shell cylinders (about tV inch diameter and li long) 

 has a perforation but little more than a millimetre (or less than tV inch) in 

 diameter, and the difficulty of making it must have been very great. Cut 

 from Tivola. La Patera and Dos Pueblos. 



(9.) Several curious subcylindric beads, cut from Tivola, and exhibit- 

 ing the blue and white coloring. The longest is If inches long, about i 

 diameter in the middle, and tapering to each end except on one side, which 

 is rectilinear. The perforation (of about 1 millimetre) is so small that it 

 would be difficult to pass a thread, and probably on this account a rounded 

 notch occupies the middle, where more than half the thickness has been 

 cut away as if to free the perforation and permit threads to be passed from 

 each end and knotted separately or together at the middle. In a second 

 specimen the notch nearly reaches the perforation ; in the third the notch 

 is quite superficial, and does not reach the centre.* In some cases the 

 notch may be due to the fact that the borings from each end did not meet.

(10.) Slender blue subcylindric shell beads made of Tivola. Plate 

 XIII, Figs. 36, 37. La Patera and Dos Pueblos. 



(11.) Small thin wampum disk beads (Plate XII, Figs 3, 4, 5), from 

 about & to 4 inch in size ; cut from univalve shells, and therefore slightly 

 concave and convex on the opposite sides. One specimen is not completely 

 rounded, and the unfinished perforation has been commenced on one side. 

 A few are flat as if worked from the solid shell. Plate XII, Fig. 6. La 

 Patera and Dos Pueblos. 



* Other examples of this form received since the beads, were examined by Dr. Haldeman show 

 that the notches were subsequently filled with asphaltum even with the surface of the shell. One 

 specimen with the asphaltum filling removed from the notch, and shown under the figure, is represented 

 by Fig. 42 of the plate ; and a second specimen with a bunch of asphaltum in place, the outline of 

 which can be distinctly seen by using a lens, is shown in Fig. 43. Figs. 44, 45, and 46 exhibit the three 

 specimens referred to in particular by Dr. Haldeman, in two of which the notch has been but partly 

 cut to the intended depth. — F. W. P.
