 pp. Ii>4-lf>0'). — The tabulated result.s show that superphosphate, steamed l)one dust, 

 and Thomas slag invariably gave the ))est results, while kainit diminished the yield.

 of potatoes grown on unmanured soil is compared with the comi)osition of tul)ers 

 grown on soil which received 20 tons of barnyard manure or an application of 5 (-wt. 

 of super])hosphate, 2 cwt. of muriate of potash, and 2 cwt. of sulphate of ammonia |)er

 iVcsw, 28 (1901), A'o.s. 101, pp. 836, 837 ; 102, pp. 851, ^'■5^-').— These exi)eriments 

 were carried on for years. The results show that this variety of rye is ver\- resist- 

 ant to unfavorable winter weather. The average weight of the rye for the entire 

 period was 71 kg. per hectoliter, and the average proportion of grain to straw was as 

 55: 100. Cooperative tests showed that it was the best variety for many sections, 

 but that in some localities the requirements of soil and climate for its successful culture 

 could not l)e fultilled.

 for this entire series show an average sugar content of 15.61 per cent and a purity of 

 87.49 per cent. The average yield of beets per acre was 17 tons and 495 lbs.
