SCANDINAVIAN SEED-CONTROL STATIONS. 15 



stations employ additional temporary help during the rush of the sea- 

 son. The largest Scandinavian seed station, the Danish seed control, 

 is officered as follows: 1 director, 1 first assistant (bookkeeping and 

 correspondence), 1 gardener, and 9 assistants; the latter and the first 

 assistant are women. 



The larger stations are supplied with Jacobseu's germination appa- 

 ratus; others use that of Strokirk or Nobbe's plates. The Nobbe ther- 

 mostat for seed examinations or larger thermostats are often found. 

 Other apparatus met with are Stjeruquist seed examiner, Stebler dia- 

 phanoscope, Sommer and Eunge liter weight, jSobbe seed duster 

 ("spreufege"), Svalof seed-coat crusher, "seed horn," Maercker seed 

 marker, analytical balance, microscopes, pocket lenses, sieves, etc. 



As important as any of the preceding apparatus are the standard 

 collections of pure seeds of cultivated plants and of the different weeds. 

 These collections are invaluable for identifying foreign seeds in sam- 

 ples received for examination. Mention should also be made of the 

 reference library with which the stations (or the officers privately) are 

 supplied, consisting, first of all, of manuals on seeds and seed testing 

 (Nobbe, Harz, .Settegast), and of works on botany, microscopy, tech- 

 nology, etc. 



Whenever tests are reported by any seed-control station, blanks are 

 furnished stating the results of the examinations. These are generally 

 reported on a printed form in which the percentages, etc., are tabulated 

 so as to show the value of the seed at a glance.
