Report on the reforestation of waste lands in southern Ontario, 1908. 

 E. J. Zavitz Cioninta: Onldiio Dc/it. Af/r., I'.IU9, />/>. .iS, jif/s. .>l). — In this rejiort 

 the author describes and jjjives maps of the various districts of soul hern Ontario, 

 discusses the present condition of the waste lands, and presents tij^ures to show 

 the financial possibility of artificially reforesting these lands at a i)rofit. The 

 conclusion Is reached that on large areas where no seed trees of commercial 

 species exist, it will be impossible to obtain satisfactory new natural growth 

 within a reasonable time, and the ipolicy of putting these lands under forest 

 management is advocated.

Para rubber cultivation, C. Mathieu (Culture du Caoutchouc dc Para. 

 Pa7is, 1909. pp. 11+201. figs. J/B). — This work, which is offered as a manual of 

 rubber cultivation in Malaysia, is printed both in English and in French. Part 

 1 deals with the problems which confront the prospective settler, such as the 

 selection and acquirement of land, location and construction of dwelling houses 

 and other buildings, methods of living, the labor question, etc. Part 2 dis-

Distribution of [Guayule] rubber in different parts of the shrub, T. 

 WniTTELSEY (.Jour. Iitdiix. and Engin. Clirm., 1 (1909), .Yo. .'/, pp. 2.'/7-2.'/9, 

 dgms. 2). — Analytical methods and data are given of an investigation relative 

 to the distribution of Guayule rubber in different parts of the plant. 



In a previous paper on this subject (E. S. R., 17, p. 257), Endlich reported 

 that the ratio of the rubber found in the bark to that found in the wood is 

 approximately 7 : 2. The data secured from the present investigation indicate 

 that the trunk wood contains no rubber, although it does contain a small per- 

 centage of a rubber-like resin which might be mistaken for rubber when the 

 extraction is made directly with tetrachlorid. Analyses of the whole plant
