FEEDING. 



The hay used in each of the experiments was run through 

 a hand feed cutter gauged to cut about one and one-half inch 

 lengths. The cut hay dropped directly from the feed cutter 

 into paper sacks of uniform size and weight and of a capacity 

 somewhat greater than the amount of feed required for one 

 wether at one feeding. 



The methods of sampling will be taken up under each 

 experiment, since different methods were used. 



Each experiment was conducted for twelve days, the 

 wethers being fed twice daily during that time, the amount 

 fed for the last ten days of each experiment being equal at 

 each meal. By the end of the second day of the experiment it 

 was determined about what amount of the fodder each wether 

 would eat without leaving much waste, and the contents of 

 twenty sacks were reduced to the required amount. Thus the 

 only work necessary at the feeding hour was the emptying of 

 a sack of feed into the feed box. 



When edible portions of a previous meal were found in 

 the feed box at feeding time, they were left there for a day 

 or two in order to give opportunity for their consumption 

 later. If there was still waste material in the feed box at the 

 end of a day or two, it was removed, weighed, and analyzed. 



FECES. 



At 8 a. m. on the eighth day the feces sacks were attached, 

 and they were removed at 8 a. m. on the thirteenth day. The 

 feces were removed daily and taken to the chemical laboratory, 

 weighed and mixed thoroughly. One-tenth was taken out and 

 dried as quickly as possible to prevent fermentation. After the 

 experiment was finished, a composite sample was prepared by 

 grinding and quartering until the desired amount was ob- 

 tained. This was ground until all would pass a sieve with 

 round openings one millimeter in diameter, bottled in glass- 

 stoppered bottles, and placed in the dark to await analysis.
