 Zimiuerniau, IJiickeye, iiud Rod May varieties were sown aloue and in 

 mixtures of twos and of all three. The tabulated i-esults show that in 

 eai'h case the yield where two varieties were mixed was larger than tlu* 

 average yield of the same two varieties when used alone. Thus when 

 Zimmerman and Buckeye were sown singly the aAcrage jield was 

 38.41 bushels, but when a mixture of the two was used tlie yield was 43 

 bushels per acre, etc. The lowest yield (39..33 bushels) was where a 

 mixture of the three varieties was sown, being lower than the average 

 of these three varieties when sown singly. 



I'lfrcfs of past)! rill (/ irJieot (pp. 11, 12). — Trials of wheat sown Septem- 

 IxT 1."), on tiftccn plats, on five of which cows were pastured in October 

 and November, and on five others in April, showed an average gain of 

 l.."» bushels of wheat per acre on the five ])lats not pastured over those 

 ]>astured. '^ Whether the food obtained by pasturing will equal the 

 value rei)resented by this difference in yield, can not be determined on 

 so small a scale. This pasturing of wheat is an imx)ortant practical 

 question. Many farmers place no small dependence on the food that 

 their wheat fields furnish in fall and spring, and cattle will occasionally 

 even run on the wheat all winter." It is suggested that a wet clay soil 

 would be more liable to injury from this practice than a dry one. 



Contiiiuouii eroppiiui n-itk wheat (pp. 12, 13). — The yields of Avheat on 

 an acre of medium heavy loam land without numure of any kind, are 

 tabulated for each year since 1880, Avhen tbe experiment was com 

 menced. Excluding 2 years when the croi) was wniter-killed, tlie 

 average yield ]>er year Iras been 29.27 bushels. The yield in 1891 was 

 3(^.75 bushels. 



Rotation experiments (pj). 13-19). — The plan is given at considerable 

 length of two series of experiments in rotation, " with wheat as the 

 basis, with a view to ascertain what system of cropping will yield the 

 best returns." The .\ield of wheat for 1891 is tabulated. As this is 

 the first year's crop of one series and the second of the other, ]u> special 

 interest attaches to the results as yet. 



Test of varieties (j)p. 19-46). — Data are given for 240 varieties of 

 wheat tested at the station during the past year. Arrangements ha\e 

 been made by which photographs of the heads of the varieties tested 

 will be furnished to all who may desire them, at a cost of $2.50 for the 

 entire set.
