The pecuniary valuation of the nitrogenous substances as 

 compared with that of the non-nitrogenous substances is quite 

 frequently stated as being equal to 5 : 1 (3.4 cents : .6 cents 

 per pound). Fat is valued at a higher price than nitrogenous 

 substances = 6.26* : 5. The price of every one of these three 

 groups changes in different classes of fodder substances. It 

 is counted highest in those substances where the highest rate 

 of digestibility is noticed ; for instance, in grains it is higher 

 than in hay; in the latter, higher than in some kinds of 

 straw materials. I am not prepared, at present, to give defi- 

 nite numerical values based upon our own market-prices, but 

 hope to be able to do so at an early date. The above-stated 

 relative values are based upon German market-prices. 



The varieties of sweet-corns are, on account of their peculiar 

 and superior composition, the most valuable kinds we have for 

 feeding-purposes : they do not enter here into the discussion. 



There is apparently no marked distinction between a good 

 sample of Eastern and a good sample of Western or South- 

 ern corn. The Eastern, cultivated and harvested with better 

 care, as a rule, than the bulk of the Western corn, seems to 

 be the safer article. 



Judging from the above results, it is but reasonable to 

 assume that a more or less careful system of cultivation and 

 harvesting would cause as striking variations in the chemical 

 composition of every one of the above varieties, the West- 

 ern varieties not excepted, as are noticeable in the above 

 analytical statements. A good illustration of this circum- 

 stance may be seen in samples VI. and VII., both being 

 Canada Dutton ; the former contains 12.42 per cent of nitro- 

 genous matter, the latter but 10.85 per cent, — a difference 

 of 1.57 per cent, for which £fn increase of .39 per cent of fat 

 does not compensate. The first sample was raised after a 

 heavy dressing with barnyard manure ; the latter after a light 

 one, and ranks with some Western varieties. 



The addition of the cobs to the kernels, i.e., the entire
