As a fitting supplement to Prof. Kedzie's analysis of corn given last week, we add the following results of the analysis of corn fodder by Prof. S. W. Johnson, director of the Connecticut Agricultural Experiment Station : The result of these and some other analyses are summed up in the table given below: I -Sweet corn fodder, cut August 9. II.- Sweet corn fodder, cut September 25. III.- Field corn stover, erop of 1877. IV.- Field corn fodder frora thu same farm, erop ot 1874, average of two samples V.- Composition of corn stover as giitn by Wolfl'in 1874. VI. - Swett corn, kernel. VII.- Field corn, kernel, average of flve rarietles. VIII.- Field corn, kernel, average of thirleen samples, including ten varieties, cro of 1877, growu in Michigan and anal yzed by Prof. Kedzle. IX. - Cob of sweet corn. X. -Cob of field corn, average of aix varieties ■ é r f i &á 5 2 'I " i s ■ Ut O u. J Q T.. 11.2 1.4 49.1 27-5 10.6 1: B.

The thor oughly air-dried corn-fodder containt1 7 to 10 per cent of water ; the fíele cured fodder of the erop of 1874 con tained the remarkably large propoi tion of 27 per cent of water, whic rose during the warm and damp "Win er that followed, in the fodder utored n the ham, to more than 54 per cent, r, in other words, five tons became ibont eight tons. We need only to remember that fleld-cured hay contains only about 15 per cent of water in order to realize the unusual power of ,he corn stalk to retain hygroscopic moisture, and to absorb it from the itmosphere. The kernel in the several ampies analyzed contained about 11 er cent of water and the cob about 8 er cent. The digestible nutiitive atio in the sixth column, estimated rom the proportion of digestible albuminoids on the one hand, and the dijestible carbohydrates and fat on the jther, as detei mined by Germán experments furnishes a fair means of comariiig the relative feeding value of lie different articles ; the larger or the wider this ratio the less valuable the 'odder; in the case of the corn fodder, ïowever, the ratio can hardiy be considered as satisfactorily established, since but a single trial has been made, ind that was with green fodder. rbe&a rooput analyses oi corn lodder !ut it in a tnuch better posltion aruun feeding stuffs than could be accorded to it on the basis of the older analyses, as will be seen on comparing the nutritive ratio given by Wolff with the new ratio.J
