a great lot of oil to dip with. When you get ready to dip your hogs you 
fill your tank with three or four inches of where you always filled it 
with water, and then put in three or four inches of oil on top, the 
oil rises to the top always. The hog goes down through the oil and 
comes out oiled all over. No one can afford to feed even cheap corn to 
lice and lice live on the very substance of the hog. They do not eat 
the flesh but they drink the blood from which the flesh is formed. Much 
less can a farmer feed sixty-five per cent corn to an innumerable herd of 
vermin and dead beat boarders. 
I think hogs should be fed at regular hours as near as possible, and 
it is a good idea to notice that all come out and that none are off their 
feed. 
To obtain the greatest amount of weight from an economical point 
of view I think a good brick or cement feeding ..oor the proper thing 
to have, as it is simply impossible to feed economically in from one to 
six inches of mud half the year. I prefer a brick floor myself and they 
are in some respects superior to cement, and in my locality it only costs 
about one-half as much to build them and any one can do the work. 
The time of marketing depends on certain conditions. The most 
profitable weight to market is around two hundred and fifty pounds as 
this weight hog is always in demand and will command the top price. 
At the close of this paper Dr. Niles of Ames said: "I would 
like to endorse what he says in regard to the use of santonin for 
worms. It is certainly a satisfactory thing. There is one question 
in connection with feeding that was not brought out very definitely. 
That was the use of self-feeders and the feeding of tankage. I 
have not had much experience in feeding corn in self-feeders but 
I have with tankage and I have foimd that we have good results. 
The first day you fill your feeder the hog will use a good deal. 
After that he will only use as much as the system requires and 
you can use tankage quite nicely. We have had good experience 
and find that Avhen a hog is out of condition we can tone it up 
with tankage." 
Earl Addy of Parnell, Missouri, said: ''I think we have struck 
something down in Missouri in the way of an economical feed that 
is pretty good and that is corn hearts. We first put eighty-five 
head on two hundred pounds of corn hearts and in thirty-eight 
days they had gained a hundred pounds at a cost of a dollar and 
twenty-five cents a hundred." 
L. C. Rose of Prescott, Iowa, to whom was assigned the subject 
of "Young Pigs and Their Ailments," failed to respond. The 
discussion of the question, however, brought forth the following 
remarks :
