"In collecting the excreiuent duck bags 6 by 12 in. in size were used. The bottom 

 of those bags was so coiistriicted as to l)e closed by means of one side extendin"- 

 longer than the other and buttoning up over the opening; thus furnishing a means 

 of c(dletting the excrement of the day without removing the bags from the sheep.''

An experiment was also made with 2 lots of 5 and C sheep to test the 

 relative digestibility of hairy vetch (fed green) and hairy vetch hay. 

 The methods followed were in general those described above. The 

 results are briefly summarized in the following table:
