though the moisture in the silage ration was six times as much as 
in the contrasted grain ration 16 per ct. more water was required 
under it than under the ration of grain. 
An account was kept of the manure from several pens and the 
analyses made showed the manure from the silage fed pens but little 
inferior in value to that from the other pens. From the average 
records it was estimated, at the valuations then given to the essen- 
tial fertilizing constituents in manures, that the manure was worth 
from $1.80 to $1.90 per year for every 100 pounds live weight fed. 
PRICKLY COMFREY.! 
Two pens of young pigs when fed a ration in which prickly 
comfrey (green) constituted about go per ct. of the total food and 
supplied about 58 per ct. of the dry matter lost steadily in weight 
for three weeks. Two lots of older pigs fed comfrey to the extent 
of over 50 per ct. of the total food, 15 per ct. of the total dry matter 
being supplied by it, gained in weight, but not at a profitable rate. 
Two other lots of larger pigs fed a ration in which comfrey con- 
situted about 35 per ct. of the total food and supplied 12 per ct. 
of the dry matter, maintained a profitable rate of growth though 
inferior to that usually made under ordinary feeding of grain and 
skim milk. 
With the four lots by which gains were made, those having salt 
at the rate of about % oz. per day per 100 pounds live weight 
required less food for the same increase in weight than those with- 
- out salt, 13 per ct. less in one instance and about 34 per ct. less in 
the other. 
CLOVER FOR PIGS.” 
When fresh red clover was fed for several weeks to a pen of 
young pigs to the extent of about go per ct. of the total food the 
increase in weight was so slow that there was a loss from the grain 
fed with it even with no value given to the clover. Four other lots 
of pigs were fed clover to the extent of from 86 to 88 per ct. of 
the fresh food and with two of the lots there was the same slow 
and unprofitable rate of growth. The two other lots, having the 
same ration, with salt added to the amount of % ounce per day for 
every 100 pounds live weight, made much faster growth but the
