 shewing the distribution of trees in the district. 



In 1902, the Forestry department of Switzerland initiated 

 an elaborate study of all the woodland plants and forests of the 

 country, the work being directed by Dr. J. Coaz, chief inspector 

 of forests, and Prof. C. Schroter. In connection with this a 

 small booklet was prepared giving suggestions as to the obser- 

 vations to be made, and the nature of the information required, 

 such as habitats, frequency, limits, exposure, and the like, and 

 some hundreds of these were distributed to the foresters through- 

 out Switzerland. All the Swiss forests are under Government 

 control, and an official notice was sent out requiring all foresters 

 to make the required observations and fill up the schedules. 

 The Kanton of Geneva appointed a botanist especially to 

 superintend this work in their area, and the results obtained, 

 together with the special investigations of the authors are now 

 printed. This part * being the first of twenty or more, each 

 illustrated with photographs, coloured maps, etc., the whole 

 forming when complete, a very elaborate work. The cost of 

 preparation and publication is defrayed by the Government. 



Moorlands. — Considerable progress has been made in 

 Switzerland in the study of moorland vegetation and the com- 

 position of peat. The most important contribution to this 

 subject is the large volume ' Die Moore der Schweiz,' 1904, 

 by Friih and Schroter. This splendid volume is the outcome 

 of a Commission appointed and subsidised by the ' Schweizer- 

 ische naturforschende Gesellschaft.' It is probably the most 

 complete account of the moors of a country that has ever been 

 published. It contains over 700 pages, has an excellent map, 

 and many illustrations of the microscopical structure of peat, 

 etc. This work not only summarises the results of previous 

 observers as Lesquereux, Friih, Hebler, Neuweiler, Schroter, 

 Diiggeli and others, but gives the results of special and prolonged 

 observations of the authors. Diiggeli's paper, f is of special in- 

 terest in that he has made a detailed study of an area in the 

 Sihltal, near Einsiedeln, which, in the near future, will be sub-
