The sheep increased in value at the rate of lojd. 

 per head per week during the time they were being 

 experimentally fed, but one must bear in mind they 

 were revalued at the beginning of the experimental 

 period. These experiments also show that one can 

 purchase store sheep at approximately the same price 

 per pound as one expects to get for them live weight 

 when fattened. The store price has varied from 4d. 

 to 4|d. per Ib. live weight, and the sale price has 

 come out exactly the same in 1903-4, and less than 

 Jd. per Ib. difference in the other two years. The sheep 

 weighed 9 to 10 stones live weight when fat. 



The return for an acre (20 tons) of roots consumed, 

 after paying for hay, cake, and meal at market price,

 with the manurial value of the cake and hay taken 

 into account, 12, iSs. 4d. per acre.
