Composition of the soils of the Canton of Redon as regards lime, 

 magnesia, potash, and nitrogen, G. Lechaktiek {('omjif. ll<ii<L 

 Acad. >Sci Purls, ISO {1900), No. 1S\ pp. 1163-11G6; abs. in Jour. 

 Chevi. Soe. [London], 78 (1900), No. JtS2, 11, p>. ^J^).— Analyses are 

 reported of soils derived from granite, pre-Cambrian, Silurian, Upper 

 Silurian, and ancient and modern alluvium formations. The average 

 percentages of lirue varied from O.U58 in Angers schist to 0.108 in 

 Armorican sandstone soils; of magnesia, from 0.084 in granite to 0.16 

 in alluvial; and potash, from 0.232 in Angers schist to 0.577 in Poligne 

 schi.st and sandstone. Nitrogen varied from 0.109 to 0.135 percent. 



Remarks on the sand-drift problem, J. H. Maiden (Agr. Gaz. 

 Neu: ^outh Wules, 11 {1900), No. l,pp. li^-lS).—A brief report is given 

 on the attempts which have been made to prevent the drifting of sands 

 in two portions of New South Wales. 



It was found at Newcastle that depositing ashes, cinders, and shale 

 from collieries and tramways served to hold the sand to a marked 

 extent. The addition of soil and manure rendered it possible to grow 

 a number of plants. 



A list of shrubs and trees suitable for seaside planting is given, 

 together with brief notes as to their relative value. Among grasses, 

 which are the most important of sand binders, notes are given on 

 Bermuda grass, Festnca littoralh, carpet or Louisiana grass, marram 

 g\'iiB>>{Psa7n7naa7'enaria), Succharmn arundinaceuvi and S. spmitaneuni, 

 Sjjim'fex hirsutus, St. Augustine grass {StenotapTirxmn americamim), 

 and coast couch grass {Zoysia pungens).
