journal takes a soniv^wiiat more regular footing as a botanical 

 periodical by the adoption ot a subi,:ription price (^.25 per 

 copy). The publication of numbers 4, 5, and 6 was financed 

 by the United Fruit Company. 



Unless the limitations imposed by the issue of only about 

 144 small octavo pages annually are removed by the adoption 

 of a larger format, it will evidently be impossible for this journal 

 to print more than a small fraction of the rapidly increasing 

 output of papers on the botany and forestry of tropical trees. 

 A field of perhaps greater usefulness is open to it, however — 

 that of presenting, in addition to such short original notes as 

 the limits of space may permit, summary reviews of at least all 

 the important items in the current literature of the world 

 relating to its subject. That the editor has envisaged this 

 opportunity is shown by the number and variety of the reviews 

 already printed, which occupy two-fifths of the pages. 



Among the original papers, the following (all by the editor 

 unless otherwise noted) may be mentioned: in no. i, "Lapachol," 

 "Secretory cells in dicotyledonous woods," "Preliminary check 

 list of British Honduras woods" (vernacular and botanical 

 names); in no. 2, "Schizolobium: a promising source of pulp- 

 wood," "Forest conditions in southeastern Bahia, Brazil," by 

 H. M. Curran; in no. 3, "Cystoliths in wood," "Spiral tracheids 

 and fiber-tracheids;" in no. 4, "An enumeration of the Sapo- 

 taceae of Central America," by P. C. Standley (with descriptions 

 of 5 new species of Lucuma and 2 of Bumelid), "Occurrence of 

 intercellular canals in dicotyledonous woods"; in no. 5, "Notes 

 on new cabinet woods from Brazil," by K. Schmieg, "Trees of 

 the Bayano River watershed, Panama," by H. C. Kluge and 

 S. J. Record; in no. 6, "Mahogany in the upper Amazon," 

 "Mucilage cells and oil cells in the woods of the Lauraceae," 

 by H. H. Janssonius, "Some fundamental considerations of 

 specific gravity," by S. J. Record and H. D. Tiemann; in no. 

 7, "New species of trees collected in Guatemala and British 

 Honduras by Samuel J. Record," by P. C. Standley, "Trees of 

 the lower Rio Motagua Valley, Guatemala," by S. J. Record and 

 H. Kuylen, "Native woods used for railway crossties in British 

 Honduras," by G. W. E. Francis. There are also numerous 

 short notes. The journal is well printed and carefully edited.
