132 MAINE AGRICULTURAL EXPERIMENT STATION. I908. 



As 'noted in the last report,* there is an apparent advantage 

 from the use of stable manure, rather than that of "chemicals." 

 This advantage, however, is not sufficient to warrant the extra 

 expense incident to hauling the manure for long distances over 

 rough roads. The supply of humus, wherein lies the chief 

 advantage of the manure, may be more cheaply applied in the 

 form of straw or meadow hay ; or, on cultivated lands, in the 

 form of green manures and cover crops. The same amount of 

 plant food as is contained in a given amount of manure may, in 

 many cases, be obtained and applied more economically in the 

 form of concentrated fertilizers. Where stable manure is 

 readily obtainable, however, and need not be hauled long dis-
