S. W. Johnson— Composition of Maize Fodder. 203 



In planting, three bushels of seed were sown per acre, in 

 drills 24 inches apart. When harvested the stalks had an 

 average height of 10-12 feet. Many stalks measured 14 feet 

 in length. Their diameter was very uniform, rarely more than 

 xi inch at the base. 



The corn thus planted and growing under clean tillage was 

 so mature and uniform that it admitted of easy mid perfect 

 curing, and yet at the same time was so tender and palatable 

 that little or no loss occurred in feeding. When harvested the 

 corn- fodder contained a good many imperfectly developed ears, 

 some of them with nearly ripe kernels. 



The corn on cutting was set up in the field in large carefully 

 made stooks, where it remained until Nov. 11, when it was 

 renioved to the barn in good order. The samples were ob- 

 tained by cutting off in each case an area of 10 feet square, 

 including 5 rows and a length of 10 feet on each row. 



The stand of the crop was so uniform, both horizontally and 

 vertically, as to ensure a very accurate result in sampling. 



Each sample was made into bundles which were at once 

 weighed, labeled and set up in the field as parts of a stook. 

 When the crop was housed the samples were again weighed. 

 They remained in the barn until February, 1875, when the use 

 of corn-fodder began for the winter. They were again weighed 

 on February 8th, and immediately were run separately through 

 a straw-cutting machine, which reduced them to half an inch 

 lengths, and in that state were brought to the laboratory. 

 ; Each sample was the i sed and weighed por- 



tions were taken for analysis. The portions were reduced to 

 , iugh a sausage-cutter 

 and by the use of ^heu- unit a tie mti m n » - nntions were 

 further pulverized by triturating with purified quartz sand. 

 The proximate analysis for water and cellulose was conducted 

 as mentioned in the previous paper. "Ether extract" was 

 obtained by the extraol eady described. Ash 



was detenii!! , at a dull red heat in a platinum 



dish. J 



The results of the analyses, calculated upon the material in 

 the different stages of d ' vas weighed, are the
