Pictorial practical tree and shrub culture, W. P. Wright and W. Dalli- 



MORE (Xeic York and London: Cassell d- Co., Ltd., 1905, pp. 152, fifjs. 28). — This 

 book is an illustrated practical manual giving concise directions for the propa- 

 gation, planting, pruning, and general management of trees and shrubs. The 

 subject-matter is chiefly the work of William Dallimore and is edited by W. P. 

 Wright. 



Several chapters are devoted to the use of trees and shrubs for forcing, for 

 the colored foliage, ornamental green leaves, autumn tints, ornamental fruits, 

 ornamental stems, climbing and trailing plants, evergreens, for undergrowth 

 and shade, hedges, and as pendulous plants. Short descriptions are given under 

 each chapter of many of the best trees and sbrubs for each of these purposes. 

 There are also lists of the best trees, conifers, and shrubs in alphabetical 

 order. 



The importance of selecting seed in practical forestry, G. F. Scott-Elliot 

 (Jour. Roy. Hort. Sot: [London], 31 (1906), pp. 1)1-150). — A discussion of the 

 experiments carried out by Prof. Adolf Engler in Zurich, in which seeds of 

 picea, pinus, sycamore, and larch wei'e obtained from trees growing at different 

 altitudes and then sowed in experimental gardens at altitudes ranging from 500 

 or (300 meters to 2,000 meters. 



It was demonstrated from these experiments that trees of very high altitudes 

 have developed the habit of forming their annual growth in a nuich shorter 

 time than trees in lower altitudes and that their seed is not suitable for culture 

 in low altitudes, but is probably the best to plant in the altitudes where the 

 parents were produced. Large seeds, whatever their origin, produce on the 

 whole larger and heavier plants than smaller ones. 



How to transplant forest trees (f7. S. Dept. Agr., Forest Serv. Circ. 61, 

 pp. If. ftg. 1). — This leaflet gives concise instructions for the cai-eful transplant- 

 ing of forest trees, both in nursery rows and in the field, together with the 

 proper season for transplanting. 



How to pack and ship young forest trees (V. *S'. Dept. Agr., Foreftt Serv. 

 Circ. 55, pp. 2, fig. 1). — Detailed directions are given for the careful handling 

 and packing of young forest trees, with the view of affording proper ventila- 

 tion and at the same time preventing the roots from drying out. 



Porest planting leaflets (U. S. Dept. Agr.. Forest Serv. Circs. 56, pp. 3: 

 57, PI). 2; 5S, pp. 3; 60, pp. 3; 62, pp. 3; 63, pp. 3; 6.',, pp. 4; 65, pp. 4; 66, 

 pp. 3; 67, pp. 6; 68, pp. 4l 70, W- S; 71, pp. 4; 72, pp. 2; 73, pp. 4; 7^/, pp. 3; 75, 

 pp. 3). — These are a series of leaflets which treat of the form and size, range, 

 habits, growth, economic uses, methods of propagation, planting, and subse- 

 (luent care of the following s])ecies of forest trees, given in order corresponding 

 to circular numbers above: Bin* oak (Qiierriis niarrocarpa) ; Jack pine (Pinus 

 :livaric(ita) ; red oak (Quercus rubra) ; red pine (Pinus resinosa) ; sbaghark 

 hickory (Hicoria orata) ; basswood (Titia aniericana) ; black locust {RoJjinia 

 pseudacacia) ; Norway spruce (Picea excelsa) ; white elm (dm us aniericana) ; 

 white pine (Pinus strobus) ; Scotch pine (Piinis si/Jrestris) ; European larch 

 (Larix curopaa) ', chestnut (Castanea dcnfata) : western yellow pine (Piiin^ 

 ponderosa) ; red cedar (Juniperus virginiana) : honey locust (Gleditsia triacan- 

 thos) ; and hackberry (CeUis occidental is). 



Eucalypts (/'. S. Dept. Agr., Forest Serr. Circ. 5!l. pp. 6). — This leaflet 

 treats of the blue gum (Eucalyptus globulus), red gum (Eucalyptus i-ostrata). 

 and sugar gum (Eucalyptus corynocalg.r). with respect to their form and size, 

 range, silvical qualities, economic uses, methods of propagation, planting, sub- 

 sequent care, and their use as wind-breaks. The estimated total cost of a 

 eucalyptus plantation, excluding land rent, at the end of 12 years is $36.86 per 

 acre, with a probable gross income of $180.
