the 3G lost in weighl during the two weeks. They were on rape, and 
only 4 made gains. The total loss on 36 pigs was 60 pounds, or al the 
rale of 1| pounds per pig. The 6 pigs that had been on an exclusive 
grain diet lost 18 pounds, or 3 pounds each. The 8 pigs thai had been 
on grain and clover lost L9 pounds, an average of nearly 2^ pounds 
each, and the 22 pigs that were taken from a grain and rape diet lost 
3o pounds, or 1| pounds each. 
Soiling. — The Utah Station a reports the results of seven tests of the 
value of green feed to pigs in pens and yards on full grain and one- 
fourth grain rations. In four tests the pigs were in pens and in three 
they were in open j^ards. The green feed was mainly alfalfa, but 
some waste garden products were also fed. 
During the first two years of these tests, embracing four experi- 
ments, the dry matter in the grass was estimated and included in the 
figures for feed eaten; but in the last three tests only the actual 
weight of grain fed was taken into account. The following table 
shows a summary of the results:

These results show a considerable advantage in daily gains for the 
pigs that were soiled and a similar saving in feed. The pigs in pens 
show a very marked advantage for soiling. There was an average 
daily gain of 0.23 pound more for the soiled pigs than for those on 
grain alone, and the feed required for 100 pounds gain was nearly 10 
per cent less. It is suggested that these good results were due as 
much to the healthful action of such feed on the digestive system as 
to their nutrient content. 
The Ontario Agricultural College b conducted an experiment to 
compare pasturing on such feeds as vetches and rape with their feed- 
ing in pens. Disregarding the item of labor, these results show that 
soiling is very economical. The average daily consumption of feed 
by pigs in the pens was approximately -1 pounds of green feed and
