the experimental plot, but came from another part of the held where 

 the growth of the crop was not quite uniform with that of the experi- 

 mental crop. That the crop was not quite uniform within the limits of 

 the ex23erimeutal plot itself is evidenced by the fact that the silage was 

 also shghtly richer in protein than would be anticipated from a study of 

 the losses of carbohydrates in the silo. It is not considered, however, 

 that these circumstances materially affect the main conclusions to be 

 drawn from the experiment, though they illustrate the extra difficulties 

 introduced into work dealing with a mixed crop.

The results again show good agreement between the two sheep. They
