ALFALFA—ITS GROWTH, DIGESTIBILITY, ETC. 
There was no phosphoric acid in the urine. The 
nitrogen in the urine of both animals was the same, 8.6 
parts in 1,000, equal to 1.85 per cent, of urea. 
The total solids of dry dung was 4J times as much as 
the solids of the urine. 
The amount of water drank was, in the case of No. 1, 
3.81 times the hay eaten; in the case of No. 2, 3.33 times. 
The live weight includes the food eaten, the dung, 
urine, etc. 
When the stomach alone will hold 100 to 150 pounds 
of water, and the excretion of the dung and urine is more or 
less irregular, we may expect a variation of from twenty to 
fifty pounds a day. In the experiment this was obviated, 
as much as possible, by weighing the dung and urine at 
noon and the animals at the same time, before they were 
fed or watered. 
The following table gives the live weight and refuse 
hay each day :
