4:8 Experiment Station Report. 



In the diagrams which follow, some of the leading facts 

 recorded in the tables are presented in the graphic form, so 

 that the results can be more readily compared. 



The diflferent pigs, and the kind of feed consumed by 

 them, is indicated on all the diagrams as follows : — 



A black line is given for pigs 5 and 6, which were fed 

 corn-meal only. 



A blue line is given for pigs 1, 2 and 8, which were fed 

 corn-meal with cotton-seed meal. 



A red line is given for pigs 3, 7 and 4, which were fed 

 corn-meal witb bran. 



An interrupted line, blue and red, is given for pigs 9 and 

 10, which were fed corn-meal with bran and cotton-seed meal. 



A scale at the side of the diagrams will show the weights 

 indicated. 



On diagram 1, the actual weight of each pig is given for 

 each week, and the gain or loss can be readily traced. 



In diagram 2, the initial weights are reduced to a common 

 standard of one hundred pounds, and the lines show the 

 gain or loss for each week for each one hundred pounds of 

 live weight. 



The dry substance of feed consumed per week, for each 

 one hundred pounds of live weight, is given in diagram 3, 

 and the dry substance of food consumed, required to pro- 

 duce one pound of increase in live weight, is given in dia- 

 gram 4. 



It will be noticed that the weights of pigs 4 and 2 are 

 omitted in the tables and diagrams the last week of the 

 experiment. No. 4 seemed to be in perfect health, when 

 weighed on the morning of December 10, but a ievf min- 

 utes after he fell down in a " spasm," and died within 

 ten minutes of the first attack, apparently of apoplexy. The 

 only post-mortem indications of disease consisted in con- 

 gestion of the membranes of the brain and medulla. 



An examination will show that, in the uniform rate of 

 gain during the experiment, — in the comparatively slight 

 variations in the amount of food consumed in proportion to 

 its weight, — and in the return for feed consumed, he had 

 made one of the best records in the experiment.
