be a timely removal of the old crop of seed-bearing trees. The influence of each of 

 these factors on forest production is discussed at considerable length. The treat- 

 ment required by the regenerated areas is described, and typical examples of natural 

 regeneration of oak, ash, and beech are cited. The regeneration of Scotch fir, rais- 

 ing plantations from seed, recurrence of seed years, means for collecting seed, and 

 cost of sowing plantations are all discussed. 



The natural regeneration of oak and beecli woods, L. S. Wood {Trans. 

 English Arbor. Soc, 5 [1903-3) , pt. 2, pp. '218-290). — The relative merits of the selec- 

 tion and crop rotation systems applied to oak and beech woods in England are 

 discussed. 



The management of public and private parks, J. AVilson ( Tranx. English 

 Arhiir. Soc, .? {1902-3), pt. 2, pp. 271-277). — A discussion is given of the principles 

 of planting and managing pul)lic and private parks. 



Sa'wmills and wood-'working machinery for estates, J. Price ( Trnm^. English 

 Arbor. Soc, 5 [1902-3), pt. 2, pp. 291-306). — A discussion is given of the general 

 subject of the establishment of mills and motive power, and descriptions are given 

 of different kinds of saws and other wood-working machinery. 



Reclaiming and planting bog land, T. Conway (Trans. English Arbor. Soc, 5 

 [1902-3), pt. 2, pp. 307-315). — A description is given of various types of bog lands, 

 and suggestions are given for their draining and planting, together with a list of the 

 most suitable varieties of trees to plant. In planting bogs it is considered of advan- 

 tage to prepare the soil while draining liy composting as much as possible upon it the 

 leaves, W'eeds, grass, and other material, as well as the addition of clay and lime, the 

 latter to reduce the acidity of the soil. Where peat is present this should l)e burned, 

 or if not burned the soil should be fallowed for at least 2 years. In planting, the 

 most suitable trees for preliminary planting are said to be willows, Scotch pine, and 

 spruces. The best time for planting bogs is in the early spring. Trees planted in 

 the autumn in such wet soils generally perish. When the total area is prepared for 

 planting, the trees may be selected from the list given, which includes alders, birches, 

 Scotch pine, willows, poplars, spruces, and larch. 



Revenue from the forest of Compiegne for 1900 (Tra)is. English Arbor. Soc, 

 5 (1902-3), pt. 2, p. 229). — A tabular report is given showing the annual receipts 

 and expenditures of the forest of Compiegne, in which the gross revenue amounted 

 to 1189,218 and the total expenditures to |31,453, leaving a net revenue of $157,765 

 for the forest of 36,072 acres, or about $4.50 per acre. 



Trees on the farm, H. Pye [Jotir. Drpt. Agr. Victoria, 1 [1902), No. 9, pp. 847- 

 852). — Attention is called to the desirability of tree planting, both as wind-breaks 

 and for timber. The methods of planting and cultivation are described and lists 

 given of trees which by their growth have shown that they are adapted to the con- 

 ditions in the region for which the report is prepared. 



SEEDS— WEEDS. 



The acquisition of the germinative faculty in ripening seed, P. Maze 



[Compt. Rend. Acad. Sd. Paris, 135 [1902), No. 24, pp. 1130-1132).— The author states 

 that many experiments have been conducted to ascertain the time at which ripen- 

 ing grains attain their ability to germinate, the results obtained being more or less 

 contradictory. He gives the results of his exjieriments with peas and maize, which 

 were taken from the pod or ear at the time the seed was in the milk and placed 

 immediately one by one in test tubes furnished with 2 plugs of cotton, one of 

 which served to support the seed at the surface of the distilled water and the 

 other intercepted the entrance of micro-organisms. Under these conditions the seed 

 were kept for a considerable time at a temperature of 30° C. The maize finally gave 

 normal plants which developed vigorously, while the seedlings of the peas were dis-
