Trials at Flora, Odin, and \asbville show a marked inoreaso in yield from nse of 

 barnyard manure; those at Odin and Nashville, some increase from the use of siipt-r- 

 phosphate of lime, but iu general not enough to make its use profitable. At HellevlUe 

 neither barnyard manure nor superphosphate produced any considerable ptrcentago 

 of increase in yield. At Flora the jilats with superphosphate yielded less than those 

 without any fertilizer. In view of the results informer years, trials on a small scale 

 with superphosphate of lime and cattle tankage are recommended for wheat on the 

 light-colored soils of southern Illinois. The value of barnyard manure for these 

 soils can hardly l»e overestimate<l.

Daily vakiations in tiih milk and RrTTKii rK<)Di'<TntN «>f 

 cows, E. II. Farkington, M. S. (pp. lUKJ). — Diajjramsare ^.jiven which 

 graphicidly represent the variations in the yield of milk and in ]M'r- 

 centajie and amount of l)utter fat from «lay to day for each of two cows, 

 the vaiiations in tlie nijiht's and mornin<;'s milk of one cow, ami tlu' daily 

 variations in the mixed milk of three cows for periods of from 40 to 

 <><i days, to^iether with the daily variations in temperature. These 

 diaoframs .show for the cows under trial, the food ami jjeneral conditions 

 remaininji- constant, that, (1) there were usually very considerable, 

 clian«ies in the yield of milk of the individual cows, and the percentage 

 of butter fat in the same from day to day; (2) cows receiving the same 

 food difleied from each other as to the amount of this variation: (.S) the 

 variations from day to day in the mornin;^"s and evening's milk <M>nsid- 

 ered separately were greater tlian in the mixed milk for flie day; (4) 

 the ndxed milk of several cows was more uniform in amount and in (pial- 

 ify than the milk of individual cows; ami (.">) "as a rule the nund)er of 

 pounds of milk was low when the mean daily temperature was high and 

 the nnnd)er was high when the temi>erature was low." It was noticed 

 in the case of one cow that "when she gave a small mess of milk it had 

 a per cent of butter fat l»cl(t\v her average, and the largest nnlkings 

 were of her riclu^st milk.*" The maximum, minimum, and average daily 

 yields of milk and of butter fat from May 1 to August 1 are also tabu- 

 lated for each of six cows.
