428 EXPERIMENT STATION RECORD. 



Dining- the past year 501 lots of seeds, an increase of 221, were 

 examined, recjuiriuy 7(55 experiments. The seeds were grouped as fol- 

 lows: Lcgnininofia' ol5, (irain'nu'cv 99, other Held crop seeds 4."), for- 

 est-tree seeds 11, and miscellaneous, oo. 



As compared with the report for the previous year (E. S. R., 5, p. 333), 

 the intrinsic value of the following more important seeds showed a 

 higher ])ercentage: TrifoHiun praiensCf Medk-iKjo Jxpullna, M. satira, 

 OrniiliopHK satirus, Loiium perenne, L. italicnm, Fcxtncd ovina, Phlcum 

 pr((icii.se, and Po^r|>/'<</ry/.s'/.v,- while TrifoUum repens, T. hyhridum, Aitthyl- 

 lis vulneraria, Onohrychis sativd, Arrhenatherum elatins, Festuca duriua- 

 cula, DactyUs f/lomcrdta, and Alopeciirus prate)i.sis showed a falling off 

 in value. 



The investigation for dodder seed showed that out of 122 of red 

 clover samples, 83 were absolutely free from dodder, of 13 samples of 

 white clover 11 were free. Of lucern 3 out of (5, and timothy 4 out of 9 

 samples were dodder free. 



The probable origin of 101 specimens of seeds, mostly red clover, was 

 investigated, and it was found that in many instances native and 

 American seeds were mixed in the proportion of 2 to 1. Furthermore, 

 what was claimed as IMienish, Bohemian, and French seed proved on 

 examination to be American. There was no French seed in the market 

 owing to the drought. 



Tabular information is given showing the results of fariiiometer tests 

 of 11 samples of wheat and 4 of rye Hour, A microscopic examina- 

 tion of samples of oil cake showed that Indian species of mustard 

 had been substituted as follows: Sinapi.s ramosa, S. dichotoma. and S. 

 chinensis. 



The author has continued his study of American clover seed, endeav- 

 oring to determine by means of the weed seed the part of the country 

 in which it was grown. xi ])revious article on this same subject 

 has already appeared.' 



Culture experiments with Lespedeza striot<(, TrifoJivm alexandriniim, 

 and T. resKpinatton are reported. T. <(Je,r(indrinutii seems little adapted 

 to the region of the station, while the other two i^lants are to be 

 investigated further, they being now considered as rather promising. 



A statement of the activity and ])ublications of the station completes 

 the contributions. 



Report of the seed control station, E. Hotter {Sta. Fruit 

 Groicos^ Assn. Middle Sfyria, 2d Rpt..^ pp. So-Ss). — During the past 

 year there were examined 105 samples of clover seed, 18 of grass seed, 

 3 of beet seed, and 5 of miscellaneous seeds. Tests were made as 

 follows: For dodder seed 98, germinative ability 34, genuineness 10, 

 and purity 27; making a total of 109 experiments performed. There 

 were inspected and sealed (RKi sacks of red clover seed. 



Investigations lor admixtures showed, in the case ol 1 lot of white
