hard and more or less crystalline, generally of a dai'k-reddish color, hut 

 lighter where freshly broken, and rather heav>-. In its longest dimen- 

 sion, which is nearly along the ol)li(jue I'adial fi'acture, it is 30 cm. The 

 width at right angles to this is 16 cm. The length of the axis running 

 ()l)li(iuely across this face is 15 cm. The maximum measurements over 

 the cm-ved outer surface are 21 cm. by 3(5 cm. A polished section is 

 shown on PI. (TIL (Locality: PI. LXXX, Xo. 59a.) 



PI. LXXXVn, Fig. Ill, 5, is a view of the l)est preserved t)road side 

 of the Carr trunk, W. C, B., Xo. 1463. It shows the terminal bud, but 

 not so well as it is shown on pi. Ix, fig. 8, of the Xineteenth Annual Report 

 of the LTnited States Geological Survey, Pt. II. 



This specimen consists of the upper portion, probably more than half, 

 of a very much laterally compressed cycad. The compression is greatest 

 in the central poi'tions, Init the thinnest place is not opposite the medulla, 

 but on one side of it. The specimen is much worn on all sides, Init enough 

 is left to show that it was originally covered with the usual appendicular 

 organs. The fracture is oblique, so as to make both the sides and ends 

 unequal. The most important feature of the specimen is the smooth-woi-n 

 but still well-preserved terminal bud, which rises nearly 3 cm. above the 

 otherwise flat general surface of the trunk in the form of a small cone about 

 5 cm. in diameter at the base. It is slightly flattened at the apex, which 

 may have been due to injury. Bract scars occur around its base, but not 

 on the rest of the summit of the trunk. This indicates greater wear at a 

 short distance from the bud, and shows that the latter was originally set in 

 a depression or crow's-nest. 



The trunk is of a light color and firm consistence and of high specific 

 gravity. The height, including the terminal bud, is 21 cm. measured on 

 the median line, but one of the lower sides extends 4 cm. lower, making a 

 total of preserved substance of 25 cm. This is also about the length of the 

 longer edge, while the shorter edge is only half as great. The total length 

 of the oblique fracture is nearly 32 cm., but the major axis at the lowest 

 point at which it can he measured is 25 cm. Judging from the rate of 

 contraction, that of the lowest point represented would have been 33 cm., 

 and the maximum might have been somewhat greater than this. The 

 minor axis varies from 7 cm. at the thinnest place to 13 cm. at the summit, 

 where it is thickest. The girth at the lowest place attainable is 74 cm.
