the corn stalk in the silo for every purpose except feeding stock for 
market than to have the ears in the crib. The question is, can you 
afford to waste the most valuable part of the corn crop ? Can you 
afford at the present prices of our land to waste by-products? As 
to the cost of putting corn in the silo per acre, Ave have grown corn 
that cut twenty tons to the acre and other that cut only eight. But 
to answer the question, it would cost from fifty to ninety cents per 
ton to put it in and an acre of our Iowa land will cut about twelve 
tons to the acre. About the cost of silos. They run from $115 to 
$1,500, owing to the kind of a silo you put up and how large. A 
good stave silo to hold ten acres of corn would cost you about $260. 
Some men put up their silo in an open lot where they can get all 
around it and others have them near the barn. The only thing to 
do is to put it where you think it will be most convenient for you. 
I have known men to buy two silos and put them up because they 
had two barns. It is rather bulky to handle if you have to carry 
it to the cows but it is not heavy. It would take about a bushel 
and a half to feed two cows, sheep eat about three pounds a day, 
horses fifteen, and hogs four." 
At this point Dr. J. H. McNeill of Ames, Iowa, took up the 
subject of "Cholera Investigations and Tuberculosis,"" and made 
the following address. 
I have been lost in the discussion of silage and almost got away from 
the subject assigned me. The time is late, the subject is broad, and T 
have enough material to talk for an hour or two, but I will simply 
drop a few facts and hints that will probably do you some gocd in the 
future. 
I have talked at different times on the subject of tuberculosis and 
you have read in the farm journals and elsewhere a great deal about 
this subject. It is an old subject, but still a new one and one that you 
as swine breeders and stock raisers will have to deal with or meet in 
a short time. 
There are several points that I want to make in the relation of tuber- 
culosis to the swine industry. We usually take up the subject and discuss 
it from the viewpoint of a cattle man, the man that is breeding pure 
bred stock, the dairy man or the man who is simply dealing in common 
cross bred stock. There is a relation existing between the swine breed- 
ing industry and the cattle breeding industry. You may say, "Well I am 
not interested in that; I am simply breeding fine stock, and we have no 
cattle on the farm." But I think it is the practice of a good many 
of the stock breeders to feed some of the best animals a little milk and 
just along that line I will say that within the past year a pedigreed animal 
was purchased and taken to the college to be used in the herd. The ani- 
mal became unthrifty, showed evidences of tuberculosis. He was killed 
and proved to be tubercular. He had tuberculosis in the worst form.
