of 15.2, 14.2, uud 13.6 bu., respectively, iu 1909 to 1912, inclusive. Two winter 

 varieties of barley bave given promising results. Of these 2, Utah Winter 

 (C. I. No. 592) has yielded an average of 19.6 bu. per acre, as against 15.8 bu. 

 for Tennessee Winter (C. I. No. 257). Three spring varieties were practically 

 failures and were discarded in 1910. Black AVinter emmer has shown itself 

 adapted to conditions at Nephi, and probably will prove a valuable crop on the 

 dry farms of the Mountain States. There was no apparent difference during 

 1912 between Buffum Improved Black Winter emmer (C. I. No. 3331) and the 

 ordinary Black Winter emmer (C. I. No. 2337). ... 



" The following data obtained from the head rows are directly related to the 

 results of the plat experiments: (1) The average winter survival of the cereals 

 was about 65 per cent; (2) the tillering of the winter cereals varied with the 

 thickness of the stand; (3) the average number of culms per plant in winter 

 cereals seldom exceeded 25, though favored plants would sometimes have a 

 greater number; (4) the average yields of the head rows gave the winter cereal 

 varieties about the same rank as did the plat experiments; (5) the spring cereal 

 varieties yielded less than the winter varieties, even though a better stand was 

 obtained. . . . 



" Some work has been done with grain sorghums, broom corn, millets, and 

 prosos, but the results obtained have given little promise that these crops are 

 adapted to the dry lands of the intermountain region. 



" In the test of size of seed with both spring and winter varieties of wheat, 

 the large seed was best in number of heads produced per plant and in yield per 

 row. No great difference was observed among the different sizes of seed in the 

 percentage of survival, plants maturing, or length of heads produced. In the 

 test of different seed treatments for smut, the following points were observed : 



(1) The effect of the time of seeding on bunt depended largely on the season; 



(2) the best copper-sulphate treatment was 1 lb. of copper sulphate to 10 gal. of 

 v/ater, the seed soaked 10 minutes and dried; (3) the best formalin treatment 

 was 2.5 parts of formalin to 1,000 parts of water, the seed soaked 10 minutes 

 and kept moist 2 hours." 



Prevention of lodging- of cereals, Ziehe (Illiis. Landw. Ztg., 32 (1912), Xo. 



83, pp. 761, 762, figs. 3). — In a comparison with nitrogen and phosphorus, 

 potash gave the best results in preventing lodging, due, it is believed, to the 

 greater constitutional vigor of plants fertilized with this element. 



The influence of moisture, fertilizer, and firmness of the soil on the root 

 development of barley and wheat in early stages of growth, R. Polle

84, pis. 2). — The experiments here discussed were carried out in 2 sizes of 

 pots of the Biicherhiillen form. Sixty-four pots had a height of 20 cm. and a 

 width of 6 by 30 cm., and 32 were 40 cm. high and 6 by 20 cm. wide. Half of 

 them were filled with clay soil and half with sanely soil. The low" vessels each 

 had 2 plants and the higher ones 1 plant each. To obtain more accurate results 

 each treatment was repeated in 5 pots. Part of the pots were fertilized with 

 3/5 gm. nitrogen as nitrate of soda, 1/5 gm. P2O5 in CaH4 (P05)2. and 1/5 gm. 

 K2O in 40 per cent potassium salt, and the sandy soil received 0.5 gm. calcium 

 carbonate in addition. In a part of the pots the soil was carefully and uni- 

 formly packed in the case of both sandy and clay soils, and in the remainder the 

 2 kinds of soils were left in a loose condition. The barley was planted on June 

 11 and harvested from June 21 to 26. The wheat was planted on July 14 and 

 harvested from July 22 to 28. A unique method is described of securing the 

 roots in a normal position by means of pressing a board, provided with numer-
