Reports on forest administration in Burma for the year 1905-6, F. B. 

 Bryant et ai.. (Rpts. Forest Admin. Burma lil05-6, pp. iO'y).— This is a report 

 for the year 1905-(! on the constitution and management of State forests in the 

 Pegu, Tenasserim, northern, and southern circles of Burma, together with 

 financial statements and notes on administration. All the important features 

 of the work are presented in tabular form. The area of reserved forests at 

 the close of the year was 20,544 sq. miles. 



Experiments undertaken in the cultivation of mahogany {Swietenia mahog- 

 ani), which have been under way since 1878, are pronounced a failure as the 

 trees do not seem to do well in Burma. The rubber experiments in the Mergui 

 plantation have been successful, and an established concern of some magnitude 

 has been developed. The total expense to date in the work with rubber is 

 given as 229,871 rupees (about $73,558.72), 1,957 acres having been planted. 

 Eubber tapping experiments at the Mergui experimental garden show that 

 trees of from 4 to 5 ft. in girth yield an average of 18.08 oz., and trees of over 

 5 ft. in girth an average of 30.98 oz. of rubber per tree. The average price 

 realized for rubber was $1.30 per pound. 



Suggestions to ■woodlot ow^ners in the Ohio valley region, S. J. Record 

 {U. S. Dcpt. Agr., Forast Sero. Circ. 13S, pp. 15). — This circular is issued with 

 the view of supplying information to farmers and others in the Ohio valley 

 region concerning the proper management of their timber lands. The conclu- 

 sions, based on examinations by the Forest Service of a large number of wood- 

 lots and forest tracts in that region, are embodied in the subject-matter, which 

 treats of the present condition, status, and uses of the woodlot, the protection 

 of the woods from grazing, fire, and wind, and in felling operations, the value 

 of different species, and the model woodlot. Suggestions are given for the im- 

 provement of woodlots of different types, including the dense first-growth 

 forest, mature open stand, dense young stand, and sapling thicket. 



In addition to the Ohio valley region, most of the information contained 

 herein is applicable to southeastern Iowa, northern Missouri, and the southern 

 portions of Michigan and Wisconsin. 



Forest planting in Vermont, L. R. Jones and C. R. Pettis iVermont Sta. 

 Bui. 132. lip. 2'i, figs. 5). — This bulletin contains information relative to the 

 present outlook as to forest planting, the best kinds of trees to plant, the seed- 

 lings, etc., to be offered for sale through the State nursery in the sjiring of 1908, 

 and suggestions relative to securing stock from commercial nurserymen, plant-

"Average log" cruise, W. J. Ward (Forestry Quart., 5 (1907), No. 3, pp. 

 268-277). — An account is given of this method of estimating the volume of 

 standing timber as evolved by the writer during 2 years' experience in exam- 

 ining and purchasing timber lands on the Pacific coast. The underlying prin- 

 cii)les and theories governing the work are discussed, together with their 

 application in the field and office. 



North American gymnosperms, D. P. Penhallow (Boston, 1907, pp. YIII-{-

 gynuiosperms of North America. In its preparation a study was made of 92 

 species from North America, 29 species from Japan, and 4 species from Aus-
