Eucalypts, A. J. McClatchie {Arizona Sta. Rpt. 1902, pp. 252, 253).— \. brief 

 account is given of experiments which have been conducted in the propagation and 

 culture of various species of Eucalyptus. A heavy frost in December, following an 

 unusually warm autumn, destroyed a number of species which had withstood pre- 

 \ious low temperature.. Eticah/ptns roslrata was killed to the ground, but sent up 

 sprouts the following spring. E. salubris and E. corynocalyx were killed entirely. 

 E. rudis, E. poliianthcma, and E. leucoxylon were slightly, if at all, injured by the 

 frost and also endured well the heat of Arizona summers. These 3 species have all 

 proved adajited to the region, the first being the most desirable for general planting. 

 The results of several years' experiments and observations upon Eucalyptus have 

 been previously reported (E. S. R., 14, p. 575). 



Spontaneous groups of seedlings, A. C. Forbes {Gard. Chron., 3. ser., 32 {1902), 

 No. 829, pp. 851, 352). — The writer comments upon the tendencj'^ of different species 

 of forest trees to reproduce themselves by natural seeding. With regard to conifers 

 the only species that can be said to regenerate itself freely in England is the Scotch 

 tir and then only after a clear cutting and under conditions which remove the seed- 

 lings from tlie shade and raw humus about the parent trees. In large pure forests 

 the white pine and silver fir reproduce themselves to some extent, Imt neither the 

 larch nor spruce show any inclination to si^ontaneously restock the ground. The 

 author believes that the white pine would freely reproduce itself under shade, and 

 prove to be one of the most valuable of introduced species, except for the inability 

 of coniferous seedlings to push their way through a thick growth in these places 

 where they are most likely to germinate. The most success in natural regeneration 

 is to be expected with hardwoods, particularly the ash, beech, birch, oak, chestnut, 

 etc. Of the heavier seeds, such as the l^eech, oak, and chestnut, it is necessary that 

 they should get into the soil, and the simplest and one of the most effective methods of 

 securing this is that of cutting a portion of the parent trees as soon after the fall of the 

 seed aa possible. The treading of the woodmen, removal of timber and brusli, etc., 

 force the seeds to enter the ground where they readily germinate. On heavy ground 

 with little or no surface vegetation or humus this condition is almost indispensable. 

 It is stated that young oaks appear in numbers only when coppice has been cut 

 over during or following a year of abundant seed production. In the case of ash, 

 birch, and sycamore the seed are more widely scattered and better adapted to 

 getting worked into the soil before germination. 



The future of our public forest lands, F. Roth {Forestnj and Irrig., 8 (1902), 

 No. 12, pp. 4-)S-50')). — This is a suggestion relating to the future policy regarding the 

 control and management of the public forest lands, in which it is proposed that there 

 be withdrawn from settlement, entry, sale, or other disposition all i^ublic lands 

 which are more vahiable for forest uses than for other purposes. The tim))er and 

 other products upon such lands are to be protected and utilized according to economic 

 principles. 



Review of the lumber trade and forest interests of the South for 1902, 

 D. W. Baird {Tradesman, 48 {1903), No. 9 {24. anmud), pp. 130, 131).— The year 

 1902 is said to have ];)een a highly prosperous one for the owners, handlers, and 

 dealers of forest products in the Southern States, both in regard to the hardwoods 

 and the pines. The production capacity in the hardwood sections has increased in 

 the South in about the proportion that the timber supply of the northern section has 

 decreased. Notes are given on the timber sujjply and the demand for different kinds 

 of hardwoods, some of which are apparently increasing rapidly in favor with con- 

 sumers. The general conditions of the Southern forest region are reviewed, and it is 

 said that the heavy and constant drain upon the Southern forests has given rise to
