tinguish the grass. But when made less green and rather late in 

 the season, it appears either to be entirely freed from any injurious 

 properties or to produce scouring in a very slight degree. It is 

 important to bear in mind that hay from the same unwholesome 

 meadow, according to the condition in which it is made, affects 

 cattle very differently. 



I should have liked to examine the herbage from scouring and 

 wholesome pastures at various stages of growth, but had no oppor- 

 tunity to undertake a series of analytical examinations of the 

 green produce, and was therefore obliged to confine my exami- 

 nations to hay from sound and from scouring pastures. 



Sample, No. 1. Hay from Scouring Land on Mr. Rugg's Farm, Cossington. 

 Dried at 212 F., 100 parjs of this hay gave 



8'94 parts of mineral matter, or ash. 



In the same condition 100 parts were found to contain 



1 707 per cent, of nitrogen, which is equivalent to 

 10'668 per cent, of nitrogenized compounds. 



Sample, No. 2. Hay from Peat-Land at Meare, which does not scour. 



In a perfectly dry state this hay gave on burning 



7*11 per cent, of ash in one determination, and 

 7'14 per cent, of ash in a second determination. 



A considerable quantity was next reduced to ash, which was 

 submitted to a full analysis, when the following results were 

 obtained :

Dried at 212 F., 100 parts of the same hay furnished 



1-414 per cent, of nitrogen, which is equal to 

 8'837 per cent, of nitrogenized compounds.
