 Circ. 74. 16 p. Aug., 1919. — Kanred wheat is a hard, red, winter wheat, resembling closely 

 Turkey and Kharkof . It is resistant to winter killing, ripens early, yields more than any other 

 commercial variety in Kansas and is very resistant to leaf rust and some forms of stem rust. 

 It will probably be of commercial value in other states growing winter wheat. — L. E Melchcrs.

 Sta. Special Bull. 5 : 507-517. 1920. — Deals with milling and baking values. There are pre- 

 sented coefficients of flour absorption, and also those for volume, color and texture of loaf. 

 When these coefficients are applied to the data presented the D 5 wheat was found to be 

 worth 23 cents per bushel less than No. 1 Amber Durum, and 38 cents less than No. 1 Hard 

 Red Spring, for the years 1915-1919. The D 5 showed itself inferior in all loaf characters. —

 rotation at the Agricultural Research Institute, Pusa, India, to determine the best methods 

 of working the land of the Pusa farm, and field tests of new and improved varieties of com- 

 monly cultivated plants. A new variety of wheat (Triticum vulgare), "Hard Federation," 

 stands up well in wind and rain, and yields up to 3300 pounds per acre. — W infield Dudgeon.

 Wheat and oats experiments, 1919. Agric. Gaz. New South Wales 31 : 153-164. 1920.— Trials 

 with wheat, also oats and barley, were carried out in three districts with a number of coopera- 

 tors. The experiments dealt with the effect of fertilizing, early and late sowing, crop-harrow- 

 ing, fallowing, rate of seeding and the effect of using graded and ungraded and acclimatized 

 and unacclimatized seed. Yields and bushel weights of grain are given. Working the land 

 after the rain gave growth and returns superior to that worked only prior to the rain and
