The crop this year has been oats, of the Early Race-horse 

 variety. Tlie soil was well prepared, the crop sown May 6. 

 The growth was, so far as could be seen, unaffected by acci- 

 dental conditions. There were, however, more weeds on 

 plots 3 and 4 than elsewhere ; and, as it was impossible to 

 separate these completely in handling the crop, some of 

 them Avere weighed with the straw. The figures represent- 

 ing weights of straw for tliese plots, especially for plot 3, 

 on which weeds were most abundant, are therefore without 

 doubt to some extent misleading. The several plots pro- 

 duced yields at the following rates per acre : — 



Representing the yield of grain on plot 1 by the number 

 100, the relative standing of the other plots is shown by
