the grant of licenses to cut standing timber without the consent of the Governor-General in 

 Council. These regulations, however, do not prevent any private owner from cutting or 

 destroying the timber on his own land. There are two important administrative matters 

 (1) the conservation of existing forest areas and (2) the planting of poor land now bare of for- 

 est. A recent act has given the power to raise £200,000 for afforestation purposes, none of 

 which has yet been used. Pinus insignis is perhaps the most profitable species but may 

 have to yield first place to Douglas fir. Kauri is valuable, as it grows on poor land. White 

 pine is a valuable species but will disappear in time, as it grows only on land needed for cul- 

 tivation. A report by D. E. Hutchins on New Zealand forests, is mentioned as about to 

 be published. — E. R. Hodson.

 58-65. Mar-Apr., 1919. [Translation from Skogen, Swedish.] — Willows grown on wet 

 ground generally produce coarse, brash wood with much pith. A finer quality of wood and 

 more flexible reeds result when grown on drier ground. Good sites for willow culture are 

 medium deep, moss or grass swamps, ditched if too wet. Even pure sand, somewhat firm, 

 when not overlying gravel can be used. The presence of phosphoric acid and a small amount 

 of potash is beneficial. Frosty sites should be avoided. The sod should be broken 40 to 50 

 cm. deep in fall, fertilized by mixing 300 kgm. of Thomas-phosphate and 700 kgm. of 37 per 

 cent potash per hectare. On distinctly poor ground use 700 kgm. Chili saltpeter per hectare 

 as dressing after the appearance of new vegetation. Cuttings should be secured in December 

 or January, bundled and stored protected from drying out. Before setting out discard 40 

 cm. of the top and about 4 cm. of the bottom. — J. A. Larsen.

 of snow in the Cascade range. Monthly Weather Rev. 46: 324-327. 3 fig., 4 tab. 1918.] Jour. 

 Forestry 17: 47-50. 1919. — Studies in the United States in the last five years show that for- 

 ests retain snow between two to three weeks after the snow in the open has disappeared, and 

 that the snow waters are better absorbed in the soil under forest conditions than out in the 

 open. Further studies are urged for the benefit of the irrigation interests, engineers and for- 

 esters that the public may better understand the forest relationships. — E. N. Munns.

942. Deam, Charles C. Trees of Indiana. Indiana State Bd. Forestry Bull. 3. 299 p., 

 133 pi. 1919. — A revised edition of the 1911 report of the State Board of Forestry, with cor- 

 rections, additional notes and a new introductory chapter. Practically all the botanical 

 drawings in the bulletin were made from the author's private herbarium of trees native to 

 Indiana. He has carried on field investigations on tree distribution in the State during the 

 last fifteen years. The bulletin is of especial value to those interested in the authentic distri- 

 bution of trees in the United States, as it indicates all counties in the State in which each spe- 

 cies occurs. All publications bearing on the distribution of trees in Indiana were consulted, 

 but the author has used his field knowledge of the State in judging the correctness of all 

 reported occurrences of the different species. In the introductory part is given a list and criti- 

 cal discussion of trees reported by various authorities as occurring in the State, but which the 

 author is convinced do not occur at the present time, or never did occur as native. The list 

 of species given as not occurring includes Pinus rigida, Chamaecyparis thyoides, Populus 

 balsamifera, Hicoria aquatica, H. mi/risticaeformis, Castanea pumila, Quercus illicifolia, Q. 

 nigra, Q. phellos, Planera aquatica, Ilex opaca, Acer pennsylvanica, Nyssa aquatica, Halesia 

 di jitera and Fraxinus caroliniana. — The bulletin contains keys to families, genera and species. 

 For each species a plate shows leaves, twigs and fruit, and a discussion is added about dis- 

 tinguishing botanical characters, importance, and range of the tree in the United States and
