In considering the composition of Bronius secalinus we find 

 that the sample collected in May has r early 13 per cent more 

 water than that of the June sample, both of the samples being 

 practically the same size. In considering the constituents of 

 the dry matter, the first sample has 6.02 per cent mere fat than 

 the second, and it has also 3.51 per cent more of protein and 

 1.98 per cent more of albumimoids. The crude fiber is present 

 to the extent of 7.01 per cent over the amount in the second 

 sample. As regards the amount of nitrogen free extract, there 

 is 18.26 per cent less in the early than in the late sample. The 

 ash constituents are 2.72 per cent less in the second than in 

 the first. 



For comparison with the work done here, we have selected 

 the following analyses:
