 the concave woody zone on the other, it has a ti'ansverse and a radial

 Smillie. photojiraphei' of the National Museum, of the best j)i'e.sei-ved 

 side of the Link trunk, W. ('., H., Xo. 14S1, and is l)y far the linc'st illus- 

 tration we have of that important specimen. 



The Link ti'unk consists of the uppei' poi'tion, or pei'ha|)s neai'ly 

 the whole, of a mcMlium sized trunk consideral)ly compressed latei'ally. 

 There are some indications that the somewhat even cross section seen 

 from below may have been near the true base. The summit is not 

 depressed, neither is there a conical leaf bud. and the contoui' is nearly 

 regular. Seen from the side the trunk presents a nearly semicircular 

 outline. Viewed in the direction of its longer tliameter it is somewhat 

 conical, but there are depressions of diffei'ent depths on both sides. The 

 color is a light brown, drab, or fawn, the substance is soft and friable, 

 and the specific gravity is low. The maximum height in an erect posi- 

 tion is 25 cm., the major axis measured across the lower end is 39 cm., 

 and the minor 22 cm. The compression, however, is least at this point, 

 and the minimum would not exceed 12 cm., which is slightly increased 

 just below the summit. The girth at the base is 97 cm., while at about 

 the middle part it is 86 cm. (LocaUty: PI. LXXX, No. 62a.) 



PI. XCI is a view from another of Mr. Smillie's platinum prints of 

 one of the broad sides of the type specimen called the Helwig trunk, 

 W. C, B., No. 3328. This is a nearly perfect trunk, which before com- 

 pression was probably a true cone rounded off at the apex. The exterior 

 is generally well preserved, but on one side all the partitions have been 

 In-oken or worn off to the depth of 1 cm. or more, and the lower portion 

 of the other side is still more deeply worn, so as to give a somewhat even 

 surface flush with the remains of the leaf bases. The ti'unk is of a lively 

 pinkish red coloi', rather soft and sandy in its composition, and of medium 

 specific gravity. , 



The trunk stands 33 cm. high. The long diameter at the base is 31 

 cm. and this diminishes gratlually to 23 cm. just below the abrupt contrac-
