the land as a fertilizer, by the percentages given above, 75.5 per 

 cent of the nitrogen, 89.7 per cent of the phosphoric acid, and 

 potash. Column 4 in the table is the total value of the fertilizing- 

 constituents in the manure. Nitrogen is valued at 18 cents, phos- 

 phoric acid at 4.5 cents and potash at 5 cents per pound.

It will be seen from this table that the high protein feeds, 

 cottonseed meal, distillers dried grains, linseed oil meal, and 

 gluten feed, have a high manurial value per ton when fed to 

 dairy cows. - Objection might be made to these values on the 

 basis that no such values can possibly be recovered with even the 

 very best method of handling the manure. On this point, the 

 writer quotes the following from the fifteenth edition of " Feeds 

 and Feeding '' by Henry and Morrison, page 277 : 



BRITISH PRACTICE 



In Great Britain, where many of the farmers are long-periol tenants, the 

 manurial value of feeding stuflfs is recognized by law in a manner that tends 

 greatly to the betterment and permanence of her agriculture. The Agricul- 

 tural Holdings Act, which is the law governing the relations between land 

 lord and tenant, directs that when a tenant is vacating his leasehold he shall 

 be reasonably compensated for the improvements he has made. Among these, 

 credit must be given for the fertilizing value of feeding stuffs which the 

 tenant may have purchased and fed out, and also, under certain conditions, 

 for the fertilizing value of grains produced on the farm and fed to stock. 

 In order to furnish data to guide the valuers who serve in -settlement between 

 landlord and tenant, after full and extended study, Lawes, Gilbert and later 

 Voelcker and Hall of the Rothamsted Experiment Station drew up the 

 tables showing the compensation to be allowed for the fertilizing value of 

 various feeds. The recommendations, as revised in 1913 and adopted by -the 

 Central Association of Agriculture and Tenant Right Valuers, are that the 

 tenant shall be credited as follows for all manure resulting from feeding 

 purchased feeds to stock on the leasehold;
