entirely to an increase in the yield of timothy. Although the manure 

 when applied had been lying in a pile for two years and was well 

 rotted, it subsequently developed that it contained considerable 

 quantity of live red clover and alsike clover seeds. It is estimated 

 that upon these plats clover made up three-fifths to two-thirds of 

 the weight of the crop. It is evident, however, from the table on 

 page 282 that the financial returns from the use of stable manure are 

 eminently satisfactory, provided it does not cost more than 50 cents 

 a ton to apply the manure. Neither upon the oats nor upon the

timothy did the lime show any effect. It is true that in general the 

 north end of each plat on which the lime was applied seemed to pro- 

 duce better hay than the south end. This, however, is believed to 

 be due to the application of remnants of fertilizers (see page 277). 

 Since there was no line of demarkation in the growing crop between 

 the two ends of the plat, it was not deemed necessary to weigh the 

 crop from the two ends separately.
