testing institutions at Zurich, Eberswalde and Hamburg, and a num- 

 ber of others in Europe, as, for example, in Holland, Norway and 

 Sweden, at any rate for the more difficult kinds of seeds, espe- 

 cially forest seeds. 



At the International Conference on Seed-testing in Hamburg in 

 1906, Dr. Stebler, Director of the Zurich Seed-testing Institution, 

 extolled the Jacobsen Apparatus as the best, especially for the 

 seeds most difficult to deal with. Chr. P. Jacobsen (184195) foun- 

 ded in 1874 the largest Danish Farm-seed Establishment, Mark- 

 fr6kontoret in Copenhagen, which was the first commercial firm 

 not only in Danmark, but probably in the whole world to 

 carry out the principle, that all seed should be tested before being 

 issued to the farmer. This firm was the pioneer of the scientific 

 seed trade, and it still plays an important part. 



During the twenty-five years that have elapsed since the Author 

 entered the seed trade, a large number of reports of the results 

 of seed tests with accompanying notes have been published by 

 him in various brochures and journals, particularly the fol- 

 lowing:

All these twelve reports appeared in the yearly Danish cata- 

 logues of the firm. 



Besides these, the following articles by the Author have been 

 published from time to time: BLidt om Frdanalysers Betydning 

 for Skovfr6et (Some remarks on the importance of Seed-testing 

 for tree seeds) and Brugbarheden af spirede Agern (On the use 

 of Germinated Acorns), in the Tidsskrift for Skovvaesen (Danish 

 Journal of Forestry) Vol. XII 1900, as well as in separate reprints.
