It will be understood that these figures are arrived at by 

 assuming that the unit value of the constituents of poultry 

 manure is approximately the same as the unit value of the chief 

 artificial fertilisers.' This point will need further investigation, 

 but the estimated values given above serve to indicate that 

 poultry manure has a considerable money value. 



The percentage of moisture in the fresh samples explains to 

 some extent the variations in value. Goose manure shows 82*6 

 per cent, of moisture, but in addition the fertilizing elements 

 are low, although the sample was taken from adult birds in the 

 month of March. Turkey manure is also not equal to that
