and snl)jected to the usual seed analysis. Tables are given showing the market price 

 of different lots of seed, the percentage of germination, number of weed seeds, and 

 the actual cost of the living seed per bushel. A list is given of 25 of the principal 

 weed seeds found in the different lots of seed and the proportion in which they 

 occurred in tlie different samples. 



Seed-testing- stations in Hungary, J. Speir ( Iraia^. IBgldand and Agr. Soc. 

 Scotland, 5. ser., 15 (1903), pp. 58-62, fig. 1). — An account is given of the organiza- 

 tion of seed-test laboratories in Hungary, their equipment and methods are described, 

 and results of tests shown. Tables are al=o given in which the rate of compensation 

 demanded for making tests, together Avith the form of the report given for all seed 

 testing, are shown.

Influence of the remedies employed in combating smut on the g-ermination 

 of seeds, R. ^Mezextzov {Ynzli. Jiiis.^. SiM\ Khoz. GJia:., 1902, No. 4^; ah.^. in Zhur. 

 Opuitn. Agron. [Jour. Expt. Landw.'], 3 {1902), pt. G, pp. 738, 7.?.9).— The author 

 presents results of experiments carried out on the Derebchinsk experiment field and 

 at the Sobyeshinsk Experiment Station. Seeds were treated with copper sulphate 

 solutions and were soaked with hot water. In one case the following results were 

 obtained: (a) In dry earth there germinated: Nontreated seeds 80 percent, soaked 

 in copper sulphate solution 36 per cent, soaked in vitriol and washed with lime 

 water 46 per cent, dipped in hot water 82 per cent, (b) In moist earth: Nontreated 

 seeds 95 per cent, soaked in copper sulphate solution 75 per cent, soaked in copper 

 sulphate solution and washed with limewater 85 per cent, steeped in hot water 96 

 per cent. Other series of experiments gave approximately the same results. — p.

On the viability of weed seed, O. Rostrup ( TkUslr. Landbr. Planicavl, 8 {1902), 

 pp. 33-35). — A cow was fed freshly cut weeds of different kinds and for 5 tlays the 

 manure was examined for weed seeds. The viability of the weed seeds and other 

 geeds found in 217 gms. of dung was subsequently determined. The total number of 

 seeds and their viability are shown in the accompanying table: 



Viabddy of weed seed from cow dung. 



A large number of other seeds were identified, but being found in only small 

 numlaers the results of the determinations of viability can not be considered of 

 general value. In order to ascertain whether the length of time during whicli the 

 seeds remain in the digestive tract influences the results of the viability determina- 

 tioiv, the germination of seeds of Sobrnum nigrum on subsequent days was deter- 

 mined, with results as follows: First day after feeding, 48 per cent; second day, 53
