The sample of clover hay was two years old. ' The 
plants were cut when the heads were half turned, and the 
whole plant was cured without the loss of any leaves or 
stems. The sample, as judged by physical properties, is 
somewhat above the average of clover hay in quality. The 
ordinary fodder analysis of this sample was, for the dry matter; 
Per cent. 
Ash .10.63 
Ether extract 2.07 
Crude protein 14.18 
Crude fiber 30 . 52 
Nitrogen-free extract 42.60 
Total 100.00 
The average percentage of nitrogen, as determined in 
the fresh sample, was 2.268, and two years later it was 2.287. 
There is no apparent change in the nitrogen content caused 
by its aging. 
The co-efhcient of digestion, as determined l.)y pepsin 
solution, was found to be 76.43 per cent., which is rather 
higher than the maximum for red clover hay, 71, and even 
higher than that of the green clover, 76. This hay was going 
on three years old at the time the determination was made. 
The amount of xylan found was 16.54 per cent., which 
is materially more than the maximum found in alfalfa hay. 
The average nitrogen-free extract in alfalfa hay is close to 
32 per cent., while the clover has 43 per cent.; and it seems 
probable that the excessive xylan found in the clover, owes 
its origin to the non-fibrous celluloses included in the nitrogen 
free extract. The fuller analysis of the sample was as follows:
