Preservation of posts by different methods, C. Seufferheld {Ber. K. Leh- 

 ramt. Weill, Obst u. Gartcnh((u, (ieisenheim, 1900-01, pp. 45, 46). — Posts used in vine- 

 yards were dipped in different solutions to preserve them against rot. The period of 

 the experiment covers 24 years. The best results have been secured with tar. Only 

 9 per cent of fir posts impregnated with tar had rotted at the end of 24 years. At the 

 end of 20 years 33 per cent of those impregnated with copper sulphate had rotted; 

 nevertheless, the ease and cheajmess with which i)osts, particularly green posts, can 

 be saturated with copper sulphate solutions seems to make its use moredesiral)le than 

 that of the tar. 



Wall and water gardens, (tert^ude Jekyll {New York: Charles Serihners' Sons, 

 1901, pp. 177, pis. 133). — The beautifying of the garden and home by the use of rocks, 

 walls, and water is made the special feature of this book. There are named and 

 described some of the rock and wall plants easiest to grow and directions given for 

 their use and culture. The making and planting of terrace and garden walls in sun 

 and shade, the construction of rock gardens, planting of lakes, ponds, small streams, 

 bogs, tubs, stream margins, etc., are discussed in as many chapters and richly illus- 

 trated. Water lilies, their uses, and the varieties best adapted for different purposes, 

 is the subject of the last chapter. The book, while written from the English stand- 

 jioint and illustrated largely from English examples, contains many helps and sug- 

 gestions for American gardeners.

 and the Kentucky blue grass has proved very satisfactory. Kedtop and perennial
