For the first six weeks they were fed an entirely grain ration, dur- 
ing the next four weeks a ration of which corn ‘ensilage formed 
about 50 per cent, and, after a week with both ensilage and com- 
frey, during the last five weeks a ration of which prickly comfrey 
formed over 50 per cent. The rations were almost identical for the 
two pens, except that, when comfrey was fed, the pen receiving salt 
These pigs were fed bran and middlings like those in the first 
experiment, with addition of corn, ensilage, or comfrey. ~ 
During the last five weeks corn meal was fed part of the hime 8 
instead of corn, but as the amount was the same and the composition he. 
very similar, as were also the results, the weights for the whole period are 
averaged together. ‘The average results obtained from these two — 
pens are given in the following table. The data given are not the 
averages of discordant portions; for the weekly averages in this, asin 
the previous experiment, approximated closely to the general results. ‘ 
In calculating the cost of food, prickly comfrey is rated at one 
dollar per ton, the same as ensilage; the manurial value is estimated 
at one dollar and forty-six cents per ton. Fi 
So far as general appearance and actions would indicate, the bh 
animals both with and without salt in their rations were in equally good a 
condition throughout the experiment.
