experiments of this nature made in the Western Mountains with 

 their very varying and trying weather conditions can only give 

 answers in a very long series of trials before conclusions are 

 permissible. Hence, if the germination per cent, of northern 

 seed was the poorest, and if the weakest plants were produced 

 by southern seed, this may be explained by other reasons than 

 the place of derivation. The recommendation, however, to avoid 

 shipments of Yellow Pine seed from one latitude to another 

 may be accepted as a safe one. 



Several other papers on reforestation of Yellow Pine and 

 Douglas Fir add to the great variety of subjects treated on the 

 92 pages. 



The reader is left with the impression that some of these data 

 were not yet ripe for printing; nevertheless, to let the profes- 

 sional world know what trend the investigations are taking is 

 also a desirable object of this publication. B. E. F.

One of the most active and productive stations, doing most ex- 

 cellent work in forest investigations is the Swedish State forest 

 experiment station, now directed by Gunnar Schotte, which 

 publishes its results in the forestry journal, Skogsvardsforen- 

 ingens Tidskrift, one of the best published technical journals, and 

 also in separate volumes, the ninth having just appeared. To 

 make results more accessible, the gist of important articles is 

 given in the German language. 



A triennial report for 1909-1911, shows that the Station does 

 its admirable work with a salary and expense item of little over 

 $4,500 per annum, four to five collaborators being engaged. 

 There are two divisions of the station, the forestal and the 

 botanical. The problems of the first include experimental areas 

 in thinnings, some 67 areas being laid out ; increment areas, some 

 12, to study stem class distribution and production in different 

 forest types; regeneration trials; heath culture (see p. 263 of 

 this issue!); cultures with different spacing; the question of 

 exotics ; the seed question ; time for sowing and planting in Norr- 

 land. Some 800 trial areas are under observation. 



The botanical division studies forest types, especially with
