Wheat. — The varieties tested Averc: Sibley's NeAv Golden, Ful- 

 caster, Raub's l^liK-k I'rolific, (lermaii Emperor, ^IcCirhee's AVliite, 

 Extra Earl}' Oaklev. The yields i)er acre of grain and straw in 1887 

 and 1888 are stated. German Emperor ga\e the best results both 

 years, and Ivanb's Black Prolific stood next in yield in 1887, and Fnl- 

 easter in 1888. The Extra Early Oakley matured earliest of all in 

 both seasons, but its yield was small. 



Oafs. — The varieties tested were AVhite Victoria, Japan, Wide 

 Awake, Henderson's Clydesdale, Welcome, Harris. The best results 

 were obtained from Japan and AVide AAvake. 



Barley. — The varieties tested were Hulless or Nepaul, and Man- 

 shury. The Xepaul ]jrodnced the heavier grain, but not as many 

 bushels per acre as the Manshury. A letter from Dr. Grunow, of 

 ]\fifflin. Wis., from whom the seed of the Manshury barley was first 

 disseminated in this country, states that the barley was first intro- 

 duced into Germany under the name of Mandschurei or Mandschurey, 

 from the country where it was found (the northwestern' part of the 

 Chinese Empire). 



Potatoes. — 1'he varieties tested Avere Thorburn, Vanguard, College 

 White, Monroe County Prize, Early Ohio, Early Beauty of Hebron, 

 Dakota Eed. None of the others equaled the College White, the 

 variety usually groAvn on the college and Station farms. 



Forage crops. — The varieties tested \\'ere prickh^ comfrey, KaiRr 

 corn. Black Eye variety of cow-pea, teosinte, white mustard, Bra- 

 zilian or flour corn. Only the first three seemed to merit further 

 trial. Samples of the white mustard, Kaffir corn, and prickly com- 

 frey, the last at three stages of develo])ment, Avere analyzed. The 

 actual yields per acre, and the qiiantities of digestible nutrients com- 

 puted by comparison of total yield, composition, and assumed co- 

 efficients of digestibility, are as folloAvs :

Test of varieties of coiix, W. H. Caldavell. B. S. (pp. -Vl-l). — 

 This is a record of experiments in 1888 to study the adaptability of 

 some A'arieties of field corn to this section and to make observations 

 upon the yield of the corn j)lanted. at difFerent stages of its groAvth.
