Report of the Danish seed control for 1896-97, O. Rostrtjp 



(Copenhagen: 1898, pp. 37). — The report shows that 1,702 samples of 

 seeds were examined from July 1, 1896, to June 30, 1897. Of this 

 number 934 samples were from seed dealers, G9 from seed growers, 508 

 from farmers, and 251 samples for original investigations. Complete 

 analyses were made of 1,184 samples, purity determinations of 243 

 samples, germination tests of 310 samples, and miscellaneous determi- 

 nations of the remainder. A summary of the results of Danish seed 

 analyses made during the period from 1887 to 1897, inclusive, is given. 

 The author states that in testing seed there are usually somewhat 

 more hard seed in legume seed during the fall months than at sowing 

 time in the spring. If all samples examined had been tested in the 

 fall, the percentage of hard seed would have been as follows: For red 

 clover, 8 per cent; white clover, 10.4 per cent; alsike clover, 4.5 per 

 cent; black medick, 4.5 per cent; lucern, G.2 per cent; and Anthyllis 

 vulneraria, 7.1 per cent; or 1.5, 0.3, 1.0, 0.2, 1.0, and 1.1 per cent, 

 respectively, greater than the results obtained in the spring.
