the vertical tangential fracture was parallel to (lie minor axis. It is 

 IS cm. high and the small diameter is i:-! cm. In the direction of the 

 lono- diameter it now measures the same, indicating that it was 20 cm. 

 Xeidier the base nor the summit is i)erfect. The medulla is wantmg 

 for the lower half of its length, leaving a hollow cavity. (Locality:

PI LXXXVU, Fig. V, 13, is a fairly good view of the Emmons 

 fragment, W. C, B., No. 3346. It comes from a tiunk that was pi'oh- 

 ably large, apparently broken from one side neai- th(> base, and havhig 

 a concave intei'ioi- corresponding to tiie convex surface. It is bi'oader 

 at the irregvilarlv broken upper end, the contracted base appearing to 

 be nearly noi-mal. One side is thicker than the other and probably 

 represents the narrow side of an elliptical trunk. It is of a very light 

 color, almost white in places, and chalky white where freshl>- bruised. 

 It is' also verv light and spongy in structure, resembling bone, and 

 friable. It is IS cm. high and has a maximum tangential width of 21 

 cm. (Locality: PL LXXX, No. 62b.) 



PI. LXXXVII, Fig. V, 14, shows the Odensoss fragment, ^^ . (\, 

 B. No. 3347. This fragment seems to belong to a small trunk which 

 was consideral)lv compressed laterally, and to represent the upper part 

 of one of the narrow sides. It is nearly half of a cone, Ijroken irregu- 

 larly at the top and somewhat obliquely at the bottom. The missing 

 central parts have left a hollow for the entire length. It is of a very 

 light color and ashy appearance, rather soft, and of low specific gravity. 

 Its maximum height is 16 cm., but on one side it is only 1 1 cm. It 

 is 14 cm. in diameter below and 8 cm. at the top. The radial thickness 

 varies from less than 5 cm. to over 7 cm. (Locality : PI. LXXX, No. 31.) 

 PI. LXXXVII, Fig. V, 16, is a somewhat unsatisfactory view of 

 the Anderson fragment, W. C, B., No. 6346, which will be fully treated 



below. 



PI. LXXXNTI, Fig. V, 18, is the only illustration we have of the 

 R. T. Donaldson fragment, No. 4, W. C, B., No. 3326. It is a very 

 small fr'agment, probably from a small trunk. It has the appearance 

 of a piece of a trunk onl>- 9 cm. in diameter, but is more probal )ly f rom 

 the thin edge of a laterally much compressed trunk.
