In 1905, the ewes bred to the Cots wold were bred to 

 the Hampshire and the ewes bred to the Rambouillet were 

 bred to the Cotswold, and so on for each lot changing breed 

 of ram each year for each lot of ewes. This furnished 

 lambs from each lot of ewes each year by ram of different 

 breed. The same ram was not used for the six years in 

 any case, but an average ram of the breed was used. 



The lambs were lambed during the latter part of 

 April and first part of May each year. The lambs were 

 allowed to run with the ewes each year on blue grass pas- 

 ture until early fall, when they were separated and put 

 in a field of rape pasture where they grazed until freezing 

 weather. On January 1, they were divided up as to breeds 

 and fed until April 1st, when they were sheared and ship- 

 ped to the Clay Robinson & Co., commission firm at Chi- 

 cago and sold on their merits.. 



The wool was shippel to H. T. Thompson & Co., 

 Chicago, graded and sold on its merits. 



The grain ration was weighed out morning and 

 evening and each lot was given all it would eat up clean 

 of a mixture of 100 pounds of shelled corn, 100 pounds of 

 oats and 25 pounds of oil-meal. Each lot was given all 

 the upland prairie hay it would eat. 



The experiment of 1908 was not as successful as those 

 for the other five years on account of an accident in early 

 fall of 1907. The number of pounds of feed for a pound 

 of gain was larger on account of the quality of the feed, 

 but the results are similar for each lot during that year. 



The number of ewes diminished as the experiment 

 progressed until in 1910 there were but 35 remaining. 



During the spring of 1910 ten of the ewes died and 

 three affected were turned over to the Veterinarian of the 

 Station for post-mortem examination. The winter of 

 1909-10 was the worst we had during this experiment. 

 The snow was deep and there were feAv pleasant days the 

 ewes would take exercise. The following is a diagnosis by
