detection, still they usually approximate sufficiently near to 

 the truth to be of great value to the farmer. Before offering 

 any comments on them, I will proceed to lay some of these 

 before the reader, in connection with a very valuable table of 

 experimental deductions.

To this Mr. Rham adds the following as equivalents of 

 100 pounds of " good hay :" — 102 lbs. latter-math hay ; 88 lbs. 

 of clover hay made before the blossom expands ; 98 lbs. of
