silage from 08 to 52°. On opening - the stacks in the early part of Jan- 

 uary, 1896, the temperature in the middle of the Blunt stack was 29° 

 and of the Hermelin stack 27°, and 48.4 per cent of the mass was 

 spoiled in the first and 35.7 per cent in the last case. The gain or loss 

 of the two sorts of silage during fermentation was lecorded. 



A feeding experiment with 20 milch cows, divided into 4 uniform lots, 

 was made to compare silage made as above and clover silage with fod- 

 der beets. The test was divided into 3 periods. In the first and third 

 periods all the lots were fed a ration consisting of 5 kg. of beets and 

 6 kg. of clover silage, with wheat bran, ground barley and oats, ground 

 peanut cake, ground rape seed cake, hay, and cut straw in addition. 

 In the second period lot 1 was fed 5 kg. each of marsh grass silage and 

 beets, lot 2 10 kg. of beets, lot 3 10 kg. of marsh grass silage, and lot 4 

 10 kg. of clover silage; all the lots receiving in addition the same 

 grain, hay, and straw ration as in the first and third periods. The 

 results are shown in the following table:

The results in every case were practically the same, and the conclu- 

 sion seems warranted that the 2 kinds of silage when fed in quanti- 

 ties not exceeding 22 lbs. per head daily have practically the same 

 value as beets.— f. ay. woll. 



Tests of pure cultures for cream ripening, N. Engstrom {18de 

 Allm. SvensTca Landtbruksmotet, Mai mil 1896. Lund, 1896, pp. 69-72). — 

 Sixteen series of trials were made with 4 pure cultures for cream ripen- 

 ing manufactured by 3 different firms. The trials were conducted 

 partly at Alnarp Dairy Institute, partly at the Hor creamery. The 

 cream used had in all cases been pasteurized at 70° C. The butter was 

 scored when a few days old, and again in a week. Only the differences 

 between the scoring of the creamery butter and the experimental lots 

 are given in the table.
