Portieth Ainnual Report of the Prof. Hastings: Yes. You come Into this room, and If material which contains the organism has been thrown on the floor, and we grind it into dust, we may breathe in the organism, but out in the open field we don't do that, because the opportunity for destroying it Is too great. I I .. !1 i Mr. Goodrich: Does the modern barn as built nowadays have a tendency to create disease among animals more than the old-fashioned way of having them around a straw stack in a shed. Prof. Hastings: Well, personally I don't think It has. It we have what we sometimes call a modern barn, one that Is air-tight, I have no doubt, but what it tends to weaken the animal. If we have the really modern barn I think it is a good deal better for the cattle than ii they ran around the straw stack. Prof. Hastings: I don't think there is any doubt about that. I read about a creamery where a fellow had a two-inch pipe for a ventilator and, he thought that was a fine idea. He could not get air through that to ventilate a henhouse with one hen in it. Mr. Glover: It might be added here, that no matter how well the barn is ventilated and lighted, If there are diseased animals in a herd the healthy cows next to them are apt to get the disease. But where the barn is well ventilated and lighted, the chance of spreading the disease is less than in the poorly ventilated and lighted barn. It may be said, that In the poorly ventilated and lighted barn there is no danger of an animal getting tuberculosis, unless the germ is present. There is no such thing as spontaneous generation of life. On the other hand, in a good lighted and well ventilated barn there is danger of spreading tuberculosis if the tubercular germ is present, but not as much danger as in the poorly lighted barn. Prof. Hastings: The disease spreads out-of-doors. It used to be asserted that it was not found among our range cattle, among cows 1 Kept outside, but it does spread among them with wonderful rapidity for the reason of their contact, and the habit of licking one another. If you have a tuberculous cow, and another cow comes along and licks her, there is an opportunity for It to spread no matter under what conditions the cattle are kept.
