An effective screen for nurseries, E. J. Zavitz (Forestry Quart., 5 (1907), 

 No. Jf, p. 367. pi. 1). — An illustrated description is given of a simple and cheap 

 form of screen used for shade in evergreen seedling work in the government

 This pamphlet is compiled from various periodicals and publications on rubber 

 culture, with a view to assembling in compact form the present information on

A new [ rubber-producing J forest species of Tonquin. I'. Eberhardt (Bui. 

 Econ. Indo-Chine, n. .sr/., W (1907). No. 65, pp. ■')76-58.j. figs. -'/). — A botanical 

 description is given, together with notes on the habitat, methods of exploitation, 

 and production of latex and rubber of a rubber-producing tree occurring in the 

 mountain region of Tonquin and locally known as Teo-Nong. An analysis of 

 the latex gave 67.6 per cent rubber. It is believed that this species, under mod- 

 ern methods of exploitation, may become of great importance.
