 of the commercial fertilizers mentioned in the note below Table 11. 

 With this the case, the manure produced by fattening- lambs is clearly 

 of much more value than many have realized.

Licensed. Inspected and Analyzed During- the Year 1905. Valuations used for nitrogen and phos- 

 phoric acid of manure are those given these fertilizing constituents in tankage; valuation used for 

 potash is as given for potash in muriate of potash. 



It will be observed that the tota* manure from lots 2 



and 3 was higher than that of the manure from lots 1 and 4. No 

 reason is apparent for the lower value of the manure from lot 4 as 

 compared with that from lot 1. The difference is so slight, however, 

 that it may safely be considered that the manure from each of the 

 two lots is of equal value.

Table 12 shows that the extra value of the manure from lots 2 

 and 3 is more than offset by the increased cost of the rations fed these 

 lots, due to the comparatively high prices of the nitrogenous con- 

 centrates used. The market conditions which prevailed during- this 

 experiment are not permanent, however, and it is very possible that 

 there may be times when the difference between the two rations as
