FeeduKj experiments irith soiling cropti (p]>. ."i.VdT). — •• Th«' j;eneral plan 

 of this ])ortion of the experiment was to «livi<le it into several ])m(»(ls 

 and feed the various soilinji' crops [fodder vovn, jrreen rye, ami rlover] 

 and the jiasture <iiass in such aimtunts that the animals should re<*eive 

 equal amounts of total dijiestibh' matter from cacli. The nutritive effect 

 was to be jud'ied of l)y the amount of milk jiroduced, takinji account of 

 its quality as determined by chemical analysis," 



There were ten feediiiii periods, the duration of which is not yiven. 

 Hay and a g,rain ration ]>er animal of 2.2 jMiunds of wheat bran and 2.2 

 pounds of a mixture of ei I ual parts of oats and corn conisely j,nound 

 were fed in ad<lition to each of the soilinji croi)s, an<l liay andjr rain 

 were fed w ithout soiling; during three periods. Two cows were used at 

 the bejjinnini;. Init one be<;imesick and had to l>e drojiped. The results

 The materials tested were each U-i\ alone. 'I'Im- pasture yrass was cut 

 ilurin^' the sprini: months from the colic;:!' campus and consisted 

 laruclN of blue "fass and white clover. It was ilrird Itetbrc l»eino-

 rate ot tw(» thiids bushels per aire, and the thin .seeded from MviX 

 sow u at the rate of one half bushel. I'.oth were fed as the ears were
