Ornamental and commercial tree planting {Transvaal Agr. Jour., 1 (1903), 

 No. 2, jy). 22-24). — An interview witli reference to the best method of planting the 

 streets of country towns with suitaltlc trees. 



Tree planting for timber and fuel, C. B. McNaugiiton {Agr. Jour. Cape Good 

 JIt)/)c, 2:> {1903), No. 4, j)}). 415-431). — An exi)eriment in tree planting is being made 

 by the municipal authorities of Oudtshoorn, South Africa. This planting is intended 

 not only for a protection of the watershed on which the water supply is caught, but 

 also for the production of timber and fuel. The scheme is highly commended not 

 only for its economic advantages, but from the indirect benefit which is expected to 

 accrue from the successful establishment of a large plantation of selected timber 

 trees. 



The author rcA'iews the various conditions of temperature, soil, exposure, etc., and 

 gives directions for the sowing of seed and planting out of trees. A considerable 

 lAnnber of trees are described whose value for planting in this locality is believed to 

 be assured and the different species are grouped according to their ])est uses. 



Trees and tree planting in the upper districts of Natal, T. R. Siit {Agr. Jour, 

 ami Min. Ecc. [Natal], 6 {1903), No. IS, pp. 657-663).— Miention is called to the 

 fact that general directions for tree planting over a large area can not be given, as a 

 number of factors must be considered. The different objects for which tree planting 

 is practiced are described and a list of different trees adapted to Natal conditions is 

 given. Most of the species described are of Australian origin, the author stating that 

 European and northeastern American species have not proved altogether satisfactory 

 when planted in that locality. 



Progress report of forest administration in Baluchistan for 1901-2, C. B. 

 Sen {Forest Bept., Balachisian, India, Bpt. 1901-2, pp. ]"I-{-22). — This is a progress 

 report on the management of the reserve forests in Baluchistan, together with the 

 forest administration report of the Zhob Agency. This area amounts to about 203 

 square miles, and the question of reserving further areas is said to be under consider- 

 ation. During the period covered by the report the natural reproduction of the forest 

 was seriously interfered with on account of the extreme dryness of the season. 



Brief rejiorts are given on the artificial reproduction in which the value of walnut, 

 ash, tamarisk, black locust, etc., is commented upon. Comparative tables are given 

 showing the ol^tput from the different forests for the 3 previous seasons, a decided 

 increase l)eing noted in the output of timber and firewood for the season covered by 

 this report. 



The relation between the mountain pine and spruce in Jutland heath cul- 

 ture, P. E. MtJLLER {Naturn: Ztschr. Land- u. Forstw., 1 {1903), Nos. S, pp. 289-306; 

 10, pp. 377-396, figs. 10). — It is claimed that through the mycorrhiza on their roots a 

 sort of symbiosis is established between the mountain pine and spruce, which should 

 be taken advantage of in forest plantings in Jutland, mixed plantations to be preferred 

 over pure stands. 



DISEASES or PLANTS. 



Studies in plant diseases, F. D. Chester {Delaware Sta. Rpt. 1903, pp. 40-46, 

 figs. 3). — Brief notes are given on experiments in the treatment of pear canker, pear 

 blight, a blight of currants, a blight of Japanese chestnuts and peach stock, and 

 spraying tomatoes for blight. During the season covered by the report the author 

 attempted to combat the pear canker, or body blight, by thorough application with 

 a brush of a formaldehyde-glycerin mixture composed of formaldehyde (40 per cent) 

 1 i)art, glycerin 2 parts, and water 17 parts. This mixture was applied to cankered 

 pear trees with such beneficial results that the author is inclined to recommend it as 

 a treatment for pear canker. Continued experiments are to be conducted along this 

 line.
