shelter, and cold winds, which predominated particularly in 1913; 1914 

 was milder, and consequently the percentage of deaths was lower. 



In the third year the old ewes were sold, and 2-tooth ewes were 

 secured of similar quality to further the experiment. Young rams 

 were also purchased, the old ones being sold with the ewes in December 

 of 1914. 



The mating of 2-tooth ewes and rams naturally resulted in somewhat 

 lower percentages in the third year, and a few weak lambs. Parti- 

 cularly was this the casie in point of the Lincoln cross, where numbers 

 of twins were born and were unable to be supported by their young 

 mothers. 



The low percentage of the Suflfolk cross in the third year can, I 

 think, be attributed to the fact that the stud which this ram was drawn 

 from had only been imported from England a few months before the 

 mating period. 



Crossbred Ewes with Lincoln Ram. 



We hope to be able to show very mucli higher lambing percentages 

 this season (the fourth year of the trials), l>ecause the ewes and rams 

 are now 4-tooths, very strong and vigorous, and the season promises to 

 supply better conditions tliau have been experienced for the past three 

 years. 



Data Recorded During Lambing and Growth of Lamb.^. 



No. L— Lincoln Cross. 



Lambing in this section seemed in tlie first two years to occur re- 

 gularly in the early part of July. In 1915 tlie lambing in this cross 

 seemed more distributed than it was in I hi' two earlier years, but tills 

 was in keeping with the other crosses, and no doul)t has for its ex- 

 planation the fact that both ewes and rams were young.
